EDITORIAL
4 September 2011 | LD+A www.ies.org
Over the past several years, there has been any number of “holy grails”
related to lighting. One was LEDs for general illumination (we’re there). The
most recent is optimal LED color rendering/appearance (we’re not there yet).
I have my own, personal holy grail for lighting: hard data that can be used
to link end-user benefit (whatever it may be in a given application) to good lighting.
No question, there have been sporadic examples over the past few years. The most
well-known is research by the Heschong Mahone Group that showed the benefit of day-
lighting in classrooms, retail space and offices (LD+A, July 2004). Among the findings:
students exposed to more daylight scored better on tests; stores with more daylight
reaped higher sales; and in office environments, better access to window views was
linked to productivity and better self-reported health and wellness among workers.
Another study linked lighting to pleasure, not business. Research in Germany showed
that the color of a room’s ambient lighting influenced the flavor of the same white wine
during three experiments (LD+A, April 2010). The Riesling wine tasted better under blue
or red light than under green and white light.
Most recently, a study released by Philips UK indicates that a “tailor-made classroom
lighting system fitted to improve the learning environment for pupils” has resulted in
improved test scores and concentration levels for these students. The system has four
dedicated settings that the teacher can select using a touchpad. The settings combine
different levels of light intensity and color tone/temperature to create a particular ambi-
ance that matches a specific task or time of day. Philips has conducted a similar study in
Tupelo, MS, and results will be released soon.
More of these application-based research studies would go a long way toward raising
lighting’s profile with consumers and decision-makers in the board room or public sector.
To put it bluntly, “what’s in it for me?” Mark Rea had it right in an article he wrote for LD+A
in 1997. He was speaking of retail sales specifically, but the sentiment can be applied to
any market served by lighting professionals: “Our customers who run retail businesses
want their socks and bologna to look good. . . . Their professional lives are defined by
socks or bologna, not by lamps and ballasts. . .”
What’s in it for me?—a succinct tagline for the next holy grail.

Short and SweetWe thought your July Editorial [on
the acronyms of LIGHTFAIR] was ter-
rific. We were even flattered that A.L.P.
made the article. I do believe that OLEDs
and LEDs are in the future, but take my
word for it, more than 85 percent of the
industry is still other than LEDs and it’s
important to give balance to the various
presentations.

I received my July issue yesterday and
as I always do, read your Editorial first.
What a great statement about what’s
happening to our culture on so many
levels. I found your effort to be very cre-
ative and humorous while also thorough.
Thanks for the entertainment.

Article of FaithI just read Jim Brodrick’s article “Can
Museums Measure Up?” (LD+A, July).
Since it highlights my research, and I have
been reported upon for 40 years, I was
keenly interested in how well it repre-
sented the concerns of the museum field.
Although the compliments must flow freely
to Brodrick’s staff, I’d be remiss in not tell-
ing you that this is the most accurate, well-
balanced and sensitive treatment I’ve ever
seen. Congratulations.

CorrectionThe Standards column in LD+A, June
(“Working Out the BUGs”) stated that
the Model Lighting Ordinance was “cur-
rently under review.” When the article
appeared, the MLO, had, in fact, already
been finalized. The article also refer-
enced the use of IES RP-20 when design-
ing security lighting in parking lots. RP-20
was withdrawn as an official IES docu-
ment several years ago.

The New Threat to Your Lamps? ChinaIncandescents may be hogging mainstream news headlines, but for many in the lighting industry a different breaking story is hitting closer to home. Last month, a host of major lighting manufacturers raised the prices of their fluorescent lamps by notable margins. GE, Philips and OSRAM Sylvania each hiked prices on their fluorescent products—including linear fluorescents and CFLs—by an overall average of 25 percent.
What’s to blame for the sudden increase? The rising cost of 17 rare-earth elements, alternately called rare-earth oxides or rare earths, which are essential to the production and operation of some of our most commonly used products, such as cell phones, magnets
and rechargeable batteries. Rare earths also comprise 85 percent of the phosphors used in fluorescent lamps.
Many of these chemical elements aren’t actually rare. In fact, some are as geologically abundant as copper or nickel. However China, which currently extracts more than
95 percent of the world’s supply, has significantly reduced its rare-earth export quotas over the past five years, causing prices to increase by up to 4,500 percent. According to the National Lighting Bureau, the world demand for the elements is set to reach 180,000 tons per year in 2012, while the world supply for next year is estimated to be less than 160,000 tons. China’s 2010 export quota, meanwhile, was only 30,000 tons.
The most staggering cost increases have occurred over the past year. For instance, lamp manufacturer Halco claims that the cost of tri-phosphor powder—a rare-earth based product used to produce T5 and T8 lamps—rose 1,000 percent from April to June. As a result, Halco and many others have raised prices for these products and will continue to re-evaluate fluo-rescent pricing on a monthly basis as material costs rise. Investment firm Sterne Agee & Leach predicts that fluorescent product prices will continue to climb for the rest of the year or longer.
In an effort to stave off cost increases, the World Trade Organization ruled in July that China broke international law by limiting the exports of raw materials like rare earths. China is expected to appeal the ruling this month, which could delay alterations to its current rare-earth quotas for several years. In the meantime, the U.S. government is hoping to stimulate its own production of the elements: last year the House of Representatives passed the “Rare Earths and Critical Materials Act,” which allows the DOE to support domestic rare-earth production through com-mercial loans.

descending into a coal mine while they are 13 stories above ground. The 41 angled steel frames
of the half-mile-long bridge suggest the support cribs used to hold up coal mine walls. RDG

A new white paper by the Institute for Electric Effi ciency shows that utilities and their customers can expect positive net benefi ts from
advanced metering infrastructure (AMI) investment over the next 20 years. For a service area of 1 million households, IEE found that the total cost for a utility to invest in AMI and associated home energy
management technologies will range from $198 million to $272 million. The AMI investment will produce operational savings between
$77 million and $208 million, and customer-driven savings between $100 million and $150 million.

Some things are worth waiting for. Nearly two years after sub-
mitting its 60-W LED replacement bulb to DOE’s Bright Tomorrow
Lighting Prize (L Prize) competition, Philips is finally getting its
reward—last month the manufacturer won the $10 million prize
in the 60-W LED
replacement cat-
egory. The DOE
established the L
Prize competition
to replace today’s
most widely used
and inefficient tech-
nologies: the 60-W incandescent bulb and the PAR38 halogen bulb
(the PAR38 portion of the competition is temporarily closed).
Submitted for the L Prize in September 2009, the Philips bulb
underwent 18 months of required performance testing conducted
by independent laboratories, field assessments, and long-term
lumen maintenance testing and stress testing under extreme con-
ditions before receiving the DOE’s seal of approval. The winning
bulb exceeded the competition’s rigorous requirements—it has a
luminous flux of 910 lumens (DOE required at least 900 lumens); 93.4
lumens per watt efficacy (90-plus required); 2,727K CCT (2,700-
3,000K required); a CRI of 93 (90-plus required); and uses only 9.7
watts (less than 10 watts required).

The lightning speed with which LEDs
have dominated the buzz in light-
ing is just amazing. There are start-
up companies promoting the use of
LEDs inside glass tubes for the replace-
ment of fluorescent lamps. Some of these
LED tube lamps are not UL listed and may
not meet the claims made for their life
expectancy. They will burn out in time, and
when they do, will those same manufactur-
ers be around to replace them? There is
no industry standard for compatibility and
those LED tube lights are not interchange-
able. The lure of this new light source is
such that caution is forgotten.
On the other hand, by using LEDs to
replace fluorescents, designers are no
longer constrained to using 2-ft or 4-ft
linear fluorescents. If a site lends itself
to a building column-spacing that is not
a multiple of 2 ft, a recessed troffer with
LEDs can be any length, width, diameter or
shape. There is a 100-story building under
construction in Shanghai with a cross sec-
tion similar to the logo of the Infinity auto-
mobile that is entirely lighted with LEDs.
The long term goal of the U.S. DOE is to
achieve zero net energy (ZNE) in buildings
in stages of 10, 20 and 30 years from now.
Reaching this goal will require enormous
efficiency improvements in building con-
struction and appliances, and vigorous
energy conservation and sophisticated
controls. However, new power genera-
tion through nuclear fuel appears to be
off the table based on what’s happened
in Japan, and the U.S. EPA’s new clean
air regulations will result in the retirement
of many old, dirty, coal-generating plants.
Pretty soon we’ll have all-electric vehicles
requiring battery recharging, which adds
to the increase in energy demand for larger
appliances and air-conditioning. Where
will all this capacity come from? There’s an
Engineering 101 adage: “Before you build
a new bridge for taller ships to pass under,
consider lowering the river.” Before we
build new generating plants, let’s consider
every possible conservation measure by
employing sophisticated technology.
JUST AROUND THE CORNERThose of you who are still enjoying elec-
tricity rates of 10 cents per kilowatt hour or
less are in for sticker shock. “Time of use
billing” is how we will soon be paying for
electricity. Home owners should be encour-
aged to install local generation, probably
photovoltaics, in order to provide distrib-
uted generation to shave peak demands
and reduce costs. Once LEDs reach the
efficacy (lumens per watt) of fluorescents
they will displace linear fluorescent and
HID sources for general and outdoor appli-
cations, as in China. The recent 20 percent
price increase for linear fluorescent lamps,
with more increases promised in the near
future, will accelerate that crossover.
We think of lighting as being on a par
with HVAC loads, each consuming about
30 percent of the total usage of electricity
in buildings, but new lighting codes are
bringing us into parity with plug loads, at
only 1 watt per sq ft, or 10 percent for each.
All lighting usage will have to be controlled
by occupancy or vacancy sensing, and will
be subject to being dimmed or disconnect-
ed during peak demand surges. We used
to think of ambient lighting as the dominant
form of illumination, but every time you use
a computer, that’s self-illuminated task
lighting. As electric car battery technol-

ogy advances, batteries will be used for
computer energy storage by recharging all
night off-peak and running all day on bat-
teries, not the grid.
There are desk-mounted task lighting
systems that can meet recommended illu-
minance levels with half the watts per sq ft
that ceiling units can provide.
THE CHERRY ON TOPAnother step toward conserving lighting
energy would be an energy code require-
ment for light room finishes. Ceiling tiles of
90 percent reflectance or higher should be
mandated along with light colored walls,
floors and even furniture. We’ll be able
to light spaces adequately with 0.5 watts
per sq ft, and all lighting will be occupant
controlled. Why waste energy warming up
dark room surfaces with light? Ultimately all
light winds up doing so, but we ought to let
it bounce around the room first. Get ready,
“white is the new beige.”
Codes should mandate that all high-rise
commercial buildings use bi-level lighting
in stairwells, where occupancy averages
around 2 percent, and in addition, all hotels,
motels and multi-story residential build-
ings should be required to use bi-level
lighting in corridors, where occupancy
averages around 30 percent.
Generating electricity with fossil fuels
(preferably natural gas) is at best about 37
percent fuel efficient. After transmission and
distribution losses you end up with a net fuel
efficiency of 30 percent. You can heat a build-
ing on site with fossil fuels with a net fuel effi-
ciency of 85 to 90 percent. Using both local
electric generation and waste heat with
combined heat and power is a mechanical
engineer’s nirvana. Finding a way to balance
an electric host, like lighting, with an equal
host for steam, like domestic hot water, will
offset peak demand and reduce cost in half.
We’ll also have to adopt a measure that
industrial facilities have been using for years,
which is to employ controls that delay the
onset of certain electric loads to times when
utility rates are off-peak, and we all will have
to participate in utility demand response
programs to avoid rolling blackouts.
The “Brave New White World” we are
facing may be an anathema to architects
and interior designers, but we have to
brighten the future for mechanical engi-
neers, who have been stuck with the same
HVAC designs for decades.

Like Pinocchio, lighting education
is not yet fully formed, but it is
evolving. Today it is driven by an
ever-maturing lighting industry in
need of an infusion of qualified young pro-
fessionals, and a plethora of promising
lighting research and technologies that
are reshaping the industry. Today’s light-
ing students must absorb a considerable
body of knowledge in order to become
relevant and contributing lighting profes-
sionals. Three recent events offer hope
for surmounting these challenges and
transforming lighting education into a liv-
ing, breathing, established field of study
that is nurtured by our industry.
In my last article I mentioned two of
these events: the IES Teachers of Lighting
Workshop (TOLW) held at the Litecontrol
facilities in Plymouth, MA, and the Lighting
Educators Summit in Milan, Italy, hosted
by the Professional Lighting Designers
Association (PLDA). I was also inspired by
the industry effort to reach out to lighting
students at LIGHTFAIR in Philadelphia
through the Student Outreach Program
and Student Design Competition. In total,
these events represent a global effort by
the industry to aggressively address the
challenges that confront lighting educa-
tion and acknowledge its critical role in
the evolution of the lighting profession.
MEETING IN MILANThis spring’s PLDA Lighting Educator
and Researcher Summit in Milan was
an energizing reset for academic-based
lighting education. Lighting educators and
researchers from all over the world met to
discuss the state of lighting education and
to help develop tools to advance academic
lighting education worldwide. More than
50 key educator delegates were in atten-
dance, representing 17 countries and
associations including IES, IALD, PLDA,
APIL, CIBSE, LET/UK and others. This
effort was led by Jean Sundin, a principal
at Office for Visual Interaction, Inc. (OVI),
and director of education for PLDA.
The goals for this two-day conference
were ambitious—to draft bachelor’s
and master’s level lighting design syllabi
through working groups and to discuss
the current state of the lighting research
landscape. The syllabi would be based on

the Architectural Lighting Fundamentals
(ALF) as mentioned in my previous article
(“Taming the Beast,” March 2011).
There were some spirited discussions,
yet at the conclusion of the conference
there was a consensus around a frame-
work for developing lighting syllabi that
addressed core competences at the
undergraduate and graduate levels. In
addition, a developed presentation was
made for a universal, and independent,
lighting research database that would
unite lighting design and lighting research
communities. But more importantly, a
dialogue between lighting educators was
started that will be strengthened through
workgroups and future conferences.
One extraordinarily useful tool that was
introduced at this summit was the Lighting
Education Wiki (https://pldaeducation.wiki-
spaces.com/ ). Like any Wiki, this site will
serve as an information cooperative that is
editable, expandable and serves as a valu-
able resource for lighting educators world-
wide. Finally, there’s an Internet-based tool
that allows the lighting education commu-
nity to share its knowledge and resources.
I guess next we will have an app for that.
ON TO MASSACHUSETTSThis year’s IES Teachers of Lighting
Workshop was a big success. It had 21
participants who were taught by nine light-
ing educators and industry professionals
(mentioned in my last article) and included
two guest instructors, Keith Yancey of Lam
Partners and myself. The camaraderie and
commitment demonstrated by these par-
ticipants was evident in the superb final
projects they produced.
This year’s participants represented
an assortment of college design pro-
grams from across the U.S. and around
the world. These attendees are not the
tenured research professors nestled in
established lighting programs, but are usu-
ally practitioner/part-time instructors who
teach a class or two within an indifferent
department. They are the most passionate
advocates for lighting at many of these
institutions and in their communities. Their

one day of the week-long workshop, yet
I was impressed by the focus and drive
that these participants, along with their

DOWN TO PHILADELPHIAThe last event that gave me hope that
lighting education is being supported by
our industry was at this year’s LIGHTFAIR
in Philadelphia. Over the last several years
LIGHTFAIR has committed to hosting light-
ing education and student events. Elly
McCloud, LIGHTFAIR executive director,
marketing conference & attendee rela-
tions, states that LFI “understands the
importance of further educating these stu-
dents and offering them access to the best
in lighting, design and education. This is
why we have established the LFI Student
Outreach program—to groom and partner
with tomorrow’s lighting future.”
This year, LIGHTFAIR sponsored the
Student Outreach Program and a lighting
fixture design competition. By partnering
with the Philadelphia Sections of the IES
and the IALD, LFI has created a competi-
tion that was open to all undergraduate
and graduate students majoring in lighting
and illumination design, architecture, engi-
neering and interior design. In addition to
the design competition, the LFI Student
Outreach Program offered a variety of other
educational and volunteer opportunities on
the trade show floor and at the conference.

meets many challenges and hardships along
the way, but overcomes them with the help
of friends. Lighting has grown up as an out-
come of the electrification of our nation into
a multi-billion dollar industry. Lighting design
started as a modernist craft to enhance
architecture, and has grown into a multi-
faceted essential building system. But it is
at the nexus of art and science, engineering
and craft that lighting education can grow
our industry into an established profession.
The Lighting Educator Summit, the Teachers
of Lighting Workshop and the LIGHTFAIR
Student Outreach program are heartening
signs that this industry is growing up, and
willing to take decisive steps to cultivate the
next generation of lighting professionals.

In case you haven’t had enough of
this subject, the activity continues in
the seemingly endless debate about
the upcoming incandescent lamp
phase-out. Since my last column on this
subject earlier this year, here is what’s
happened:
• On March 1, Representative Michelle
Bachmann (R-MN) introduced HR.429,
the Light Bulb Freedom of Choice Act.
This bill would repeal the incandescent
lamp standards in EISA 2007 unless
three criteria are met: proof of energy
cost savings claimed through the use of
the new lamps, proof that the phase-out
will reduce overall CO2 emissions by 20
percent by the year 2025, and proof that
the phase-out will not pose additional
health risks due to mercury in CFLs.
As of this writing, this bill is sitting in the
House Energy and Commerce Committee.
• Representative Joe Barton (R-TX) re-
introduced his Better Use of Light Bulbs
Act, now designated HR.2417. In addi-
tion to the repeal, two sections have
been added to the bill. Sec 3 prohibits
the use of mercury-containing lamps as
the only compliance option (which never
was the case anyway); Sec 4 prohibits
state and local jurisdictions from enact-
ing their own regulations for energy effi-
ciency or energy use of medium screw-
base, general service incandescents
(basically prohibiting states’ rights).
The Barton bill was brought directly to
the House floor on July 11, circumvent-
ing the normal committee process and
thereby requiring a two-thirds majority to
pass. The vote on July 12 did not get the
two-thirds majority; therefore, the bill is
dead, at least in its present form. By the
time you read this, there may have been
yet another attempt at repeal, in some
other form or procedure.
The debate on July 11 was broadcast
on C-SPAN. I think this is the first time I
have ever watched C-SPAN for more than
seven seconds. It was quite amazing to
see and hear light bulbs being discussed
by one of the most powerful legislative
bodies on the planet.
While all this was going on, the print
media, TV news and the blogosphere have
all been in “light bulb frenzy” mode. If
any of you have been wishing that light-
ing would get more attention with the
American public. . .well, be careful what
you wish for. Most of the stories contain
content and opinions along political lines,
with much misinformation. And, if you
really want to be amused, try reading the
responses listed below the articles and
blogs on the internet. Yikes!

other legislative subjects, please refer to

WHAT’S A CBECS?Unless you are part of the energy code
development world or involved in building
energy performance modeling, you may
not be familiar with the term “CBECS”
(pronounced “See-bex”). It stands for
Commercial Building Energy Consumption
Survey and plays an important, almost
mandatory, role in the field of building
performance evaluation.
CBECS is part of the Energy Information
Administration (EIA) which is under the
DOE. From the EIA website: The U.S. Energy
Information Administration (EIA) collects,

analyzes, and disseminates independent
and impartial energy information to promote
sound policymaking, efficient markets, and
public understanding of energy and its inter-
action with the economy and the environ-
ment. The EIA has an amazing amount of
statistical information available and is an
interesting website in and of itself.
But what about CBECS? From the
CBECS website (www.eia.gov/emeu/
cbecs) : The Commercial Buildings Energy
Consumption Survey is a national sample
survey that collects information on the
stock of U.S. commercial buildings, their
energy-related building characteristics,
and their energy consumption and expen-
ditures. Commercial buildings include all
buildings in which at least half of the floor-
space is used for a purpose that is not
residential, industrial, or agricultural, so
they include building types that might not
traditionally be considered “commercial,”
such as schools, correctional institutions,
and buildings used for religious worship.
The CBECS was first conducted in 1979;
the eighth, and most recent survey, was
conducted in 2003. CBECS is currently
conducted on a quadrennial basis. How
is the CBECS used? Information from
CBECS is the basis for many federal and
private sector energy efficiency and sus-
tainability programs, including the Energy
Star Buildings program, Leadership in
Energy and Environmental Design (LEED)
for Existing Buildings, and other building
energy labeling platforms. For example, if
one wants to benchmark a particular build-
ing’s energy consumption against similar
buildings to judge relative performance,
the CBECS data provides that benchmark.
The CBECS is also used to check computer
modeling programs against real world data.
Recently, the U.S. EIA announced that
the 2007 edition of the Commercial Building
Energy Consumption Survey would not be
released due to statistical errors and that
the 2011 edition is suspended due to lack of
funding. This is basically a disaster—while

it is possible to use 2003 data, a lot has
changed in the last four-to-eight years as
pertains to building energy consumption
due to the continuing pace of energy-
reducing retrofits and, to a lesser extent,
the construction of new buildings with
inherently lower energy consumption.
A coalition of stakeholders (including the
IES) sent a letter to several high-ranking
Congressional members to explain the need
for continued CBECS support. The amount of
money needed to continue the program this
fiscal year is $4 million—pocket change rela-
tive to the stratospheric budget numbers to
which we have become accustomed. At the
time of this writing (mid-July), several House
members have taken up the cause and deliv-
ered a wonderful colloquy on the House floor
in strong support of funding and resuming
work on the 2011 CBECS. In the meantime,
we are developing “Plan B” just in case
Congress (specifically, the Appropriations
Committee) does not save the day. Plan B
involves a public/private partnership solu-
tion. More to come . . . stay tuned.

SHEIKH ZAYED BRIDGE
28 September 2011 | LD+A www.ies.org
Call Abu Dhabi, UAE, the land of the bold gesture. Why
simply build a hotel when you can build a hotel with a
Formula 1 racetrack encapsulated by an illuminated steel
and glass shell, as was the case at the Yas Marina? When
a mammoth new mosque rises, the lighting design, alone, requires
six years, the construction lasts 15 years and the fi nished product
becomes a national icon.
Another bold gesture follows in 2011: After eight years of con-
struction, a striking new bridge—with colored light that fl ows
across its arches—creates a new eight-lane gateway from the
Dubai mainland to the island of Abu Dhabi.
The hallmark of the 842-meter (2,762-ft) long Sheikh Zayed
Bridge are the three curved steel arches of differing heights that
spring from concrete piers. The arches’ undulating shape has
been likened to that of a desert sand dune. The main arch soars to
a height of 60 meters above water level, with the road crowning
to a height of 20 meters above mean water level. In an unusual
architectural twist, the bridge’s wave-like structural form—or
“spine”—splits and diverges under the deck to the outside of the
roadway at one end of the bridge.
The lighting strategy, developed by Hollands Licht and Arup, re-
lies on subtle color-changing light that fl ows smoothly across the
bridge’s silhouetted spine both over and under the deck. This system
is complemented by linear fl uorescent luminaires tucked into “light
cells” embedded under the bridge deck, which provide white light.
FLUID SITUATION
The design scheme is steeped heavily in symbolism: “It is a met-
aphor for energy fl owing across the water [the Maqta Channel],
visualized by colors of light cross-fading from one to another while
simultaneously moving along the bridge’s spine,” says Hollands
Licht lead designer Rogier van der Heide (now chief design offi cer
and vice president at Philips), who was contacted by world-re-
nowned architect Zaha Hadid in 2000. As the sun sets, the bridge

structure appears to dematerialize due to this fl uid movement of
light. At night, the lighting renders the spine three-dimensionally
by projecting different colors on horizontal and vertical surfaces.
For its part, the roadway lighting (Philips Lighting) consists of
asymmetric metal halide luminaires that offer precise beam con-
trol so as not to interfere with the thematic lighting. By integrating
the roadway and theme lighting, van der Heide ensured that they
didn’t disturb each other and instead strengthened the overall
concept. With that goal in mind, van der Heide, in collaboration
with Hadid, designed the masts that support both the roadway
lighting and architectural lighting positioned along the deck.
More than 300 metal halide luminaires (two different fi xtures
from Martin Professional) provide the colored illumination. Along
with the pole-mounted fi xtures at deck level are luminaires that
sit under the bridge, at water level, and uplight the steel spine as it
curves under and over the deck. Dust-proof and waterproof equip-
ment was essential, says van der Heide, and both metal halide lu-
minaires used have an IP65 rating.
TELLING THE TALE
To bare Abu Dhabi’s “soul” through light, Arup’s Simone Collon
programmed 13 artistic lighting scenarios, which celebrate Abu
Dhabi’s religious traditions, festivals and other public events. In
addition, when there is a new moon, the bridge lighting comple-
ments the lighting of the nearby Grand Mosque, whose façade il-
lumination is based on the lunar cycle and seven color shifts. Once
a month, both architectural landmarks are tinted in deep blue. The
lighting scenarios “go far beyond simple color changes,” says Col-
lon. “They tell the story of a very special culture and city.”
Also helping to tell the Abu Dhabi story are fl ashes of white light
that emerge from rectangular light cells beneath the bridge deck.
This kinetic light is generated by 956 linear fl uorescent luminaires
(Martin Professional) fi tted inside these light cell compartments.
“The cell lighting is carefully integrated into the artistic concept of
the color fl ows,” says Collon. “Sometimes the light pulsates, trav-
els fast from one shore to the other or shows random patterns.”
The vibrant bridge is not only an architectural touchstone and
physical gateway to the city but is also being trumpeted as a po-
tential catalyst for economic growth in Abu Dhabi. Fortune may
literally follow the bold. ■

Mandarin, Tagalog, Spanish and Samoan—these are
just a few of the languages you might hear on any
given day at Sound Transit’s new Link light rail sta-
tion in Tukwila, WA, a Seattle suburb that boasts one
of the state’s most culturally diverse populations.
“A good number of these riders don’t speak or read English. But
even if you can’t read English, you can fi nd your way,” says Susan
June Olson, principal of the Seattle fi rm Light by Radiance, which
designed the lighting for four stations along the new light rail sys-
tem’s 13.9-mile Central Link, including the 100,000-sq ft Tukwila
International Boulevard Station. That’s because the station uses
a language all cultures understand: light. In both the exterior and
interior of the station, the lighting systems serve as wayfi nding
devices that direct patrons to and from vital areas of the com-
plex—the parking lot, connecting transportation pick-up and
drop-off points, and ticket windows.
The lighting also meets the needs of Sound Transit, the region-
al agency that owns and operates the light rail system. Primary
among its concerns was creating stations that were safe, highly
energy effi cient and easy to maintain. Olson addressed these ob-
jectives by producing light fi xture standards, which outline the
lamp and fi xture types to be used in all light rail stations. Though
they were created in 1999, the standards comply with the state’s
contemporary energy code—which mandates an LPD of 1.0 watt
per sq ft or less—without using today’s technology du jour: LEDs.
Instead, Olson selected pulse-start metal halide as the primary
lamp type for both exterior and interior lighting. At Tukwila, 3,200K
pulse-start metal halide was used for all outdoor and ground-fl oor
lighting and the majority of the interior lighting due to its energy
effi ciency and color-rendering properties. “A lot of transportation
projects use high-pressure sodium for effi ciency, but the color ren-
dering isn’t great,” says Olson. Given the area’s diverse population,
Olson wanted a source that would properly render a range of skin
tones, which “is an incredibly important element in identifying indi-
viduals, as well as rendering them on the security cameras.”
Designed to the agency’s light fi xture standards in 2003, the
$35 million Tukwila station opened in 2009 and received three
IES Illumination Awards of Merit in 2010: the Waterbury Award
for Outdoor Lighting Design, the Guth Award for Interior Lighting
Design and the Energy and Environmental Design Award.

WALK-N-RIDE
Even before visitors set foot on the complex, lighting guides
the way. Situated just off of a major highway, the glowing station
beckons riders from the road. Within the complex, exterior light-
ing directs riders to and from the station, as well as to connecting
transportation nodes within the complex. “It was a critical com-
ponent for safety. A ton of people use the station, and during rush
hour there is a lot of vehicular traffi c,” says Olson.
For example, in the 600-space park-n-ride lot, a hierarchy of fi x-
tures helps to distinguish the main spine that leads visitors from
the lot to the station. Here, the hierarchy consists of two differ-
ent fi xtures with varying pole heights: 250-W fi xtures mounted
on 40-ft-tall poles line the perimeter of the lot, while 100-W lu-
minaires on 12-ft-tall pedestrian-scale poles call attention to the
spine that runs through its center.
Luminaire location identifi es circulation routes in the open-air
ground level, where buses and cars drop off and pick up riders.
Wall-mounted area lights (Kim Lighting) defi ne the entrance of the
drive-through and 100-W luminaires mounted on custom, bright
yellow arms mark the location of waiting areas to the left of the
drop-off and pick-up lane.
INSIDE TRACK
Lighting serves as wayfi nding in the station’s interior as well. On
the second level, a row of 3,500K fl uorescent pendants guides rid-
ers to ticket vending machines, while 3,200K metal halide downlights
provide ambient illumination. The fl uorescents’ cooler color tempera-
ture makes them pop against the warmer colored downlights.
Fluorescent also highlights architectural details throughout the
complex. In the stairwells, 4-ft, linear T8 luminaires are vertically
mounted at each corner to graze the X-shaped structural metal
beams. Similar structural members on the third fl oor platform area
are revealed by fl uorescent accents mounted overhead.
Elsewhere, pulse-start metal halide illuminates the interior of
the station. Across from the fl uorescent accents on the third fl oor,
100-W, truss-mounted metal halide area lights illuminate the train
A hierarchy of lighting fi xtures helps riders navigate the outdoor complex. Pedestrian-scale luminaires line the central spine, while taller parking lot lights defi ne the site’s border. On the open-air ground level, fi xtures with custom yellow arms mark waiting area locations.

platform and tracks. The escalators that lead to the platform are
indirectly lighted by metal halide luminaires (elliptipar) that throw
light onto a 45-ft-tall white ceiling. Since all fi xtures were required
to be accessible by a 12-ft ladder for maintenance reasons, Ol-
son created a custom arm that allows “people on the third-level
platform to pull the luminaires in and relamp them.” Metal halide
likewise lights art—PAR lamps accent the sculpture that hangs
above the escalator depicting an oversized drop of milk.
The interior lighting is also notable for what it doesn’t use. Dur-
ing the day, photocells installed on each of the three levels turn the
electric sources off when there is suffi cient natural light. Designed
to consume 0.56 watts per sq ft with the lights on, the interior actu-
ally uses far less thanks to copious daylighting, an achievement that
earned it a $45,000 rebate from the local utility, Seattle City Light. ■

Round and round it goes in Toronto, but this circu-
lar story has a happy ending.
The story begins with an old circle—an un-
sightly “black hole” in the form of an abandoned
building that had marred the downtown landscape since
1988. The building in question is an historic steam train
roundhouse used for repairing and housing locomotives.
Today, a new circle has taken shape, as the roundhouse
has been transformed from an urban eyesore into a vibrant
retail center/railroad museum. And for good measure,
one more circle has been added to provide the fi nishing
touch: new façade lighting on the roundhouse that cleverly
evokes the wheel of a steam train—spokes and all.
That lighting of the 82-year-old building by Deborah
Gottesman, Gottesman Associates, Toronto, packs all
the visual impact of, well, a perfectly placed roundhouse

punch. “I love heritage lighting. I fi nd it very inspiring. If you listen
to the narrative of the building and pay attention, the design be-
comes a natural extension of the story,” says Gottesman.
Gottesman’s design, which earned a 2011 IES Illumination
Award of Merit, also includes the lighting of four historic buildings,
which were moved to the site to create the museum, the walk-
ways surrounding these buildings, railway artifacts such as tracks
and steam trains, and an old coal and sanding tower. Sensitive to
how the roundhouse and the other structures would mesh with
the urban fabric, Gottesman says the project team didn’t want
lighting that was “garish or too attention getting. We didn’t want
to blow it up; it had to be elegant and subdued.”
The historic nature of the site demanded such subtlety. Built in
1929 by Canadian Pacifi c Railway, the John Street Roundhouse
was in continuous service until 1988, able to service over 60
engines and train cars a day. Its central steam plant and 120-ft
turntable allowed engines to be moved without fi ring them up.
The 100,000-sq ft roundhouse has 32 engine repair bays and was
unique for its time in its use of daylighting: continuous clerestory
windows extend along both sides of each repair bay. In 1991, the
roundhouse was designated a Federal Heritage Building.
Today, it’s not steam trains being serviced but the general pub-
lic. Three tenants occupy the refurbished roundhouse: a brewery/
bar; a furniture retailer that caters to the downtown condo mar-
ket; and the railway museum.
With the site located in the heart of downtown, next to the Rog-
ers Centre, home of Major League Baseball’s Toronto Blue Jays, the
goal was “to give the site a presence at night,” says Gottesman.
However, this had to be accomplished without poles or any other
structural manifestation of lighting. “There were existing pathways
within the site so for liability reasons, there were to be no poles and
nothing people could play with, trip over or climb on,” says Gottes-
man. As a result, most of the luminaires on the project are discreetly
hidden. And with the city as part owner, cost control was essential;
the project ultimately came in 10 percent below budget.
EVERYTHING IS BLACK AND WHITE
Gottesman’s concept for the roundhouse was to use the idea of
a wheel of a steam train to create visual interest on the black build-
ing canvas. Since no luminaires could be mounted on the building, in-
ground 18-W LED luminaires (Beta Calco) were positioned between
each pair of doors, to highlight the building form, create rhythm and
suggest the wheel. Uplight is shielded by the soffi t above. The ground
here can settle and shift over time, so the luminaires had to be easily
accessible and adjustable for aiming and alignment of the light pat-
tern. Almost 800 linear ft of façade is illuminated consuming only 700
watts of light. The clerestory windows (which were replaced during
the renovation) are illuminated from interior lights only, highlighting
the roundhouse’s curvature.
With its large doors and glass curtain wall, the roundhouse
takes on one appearance when it’s open for business (i.e., when
the doors are open) and a different look when it’s closed. “When
the doors are open, white dominates over black in that there are
When the roundhouse doors are closed, the in-ground LED luminaires fi xtures built into wood poles (inset, left), which cast light away from the

black stripes [the open doors, themselves] on a white building [il-
luminated from within],” says Gottesman. “When the doors are
closed, black dominates over white in that there are white stripes
of light from the embedded LEDs on a black building.”
The façade is the wheel, but what about the spokes? To cre-
ate the spokes, a sharp-beam LED optic from an existing lumi-
naire was designed into 4-ft-high custom wood post luminaires.
Approximately 3 ft above the ground, the light source faces away
from the façade and is aimed at the ground, resulting in the soft
stripes of light that symbolize the spokes.
The choice of LEDs for the roundhouse was dictated in part by
Toronto’s participation in Cree’s LED City program, but they were
the most logical source, regardless. “Today LEDs would absolute-
ly be used. This project was designed two years ago. LEDs are
good in the cold and they worked well at the time; we did a mock
up and they did make sense,” says Gottesman.
ROLLING INTO TOWN
Gottesman was also responsible for deftly lighting the four or-
phan buildings (a ticket booth, cabin, shed and station) as well as
various “rolling stock” artifacts that were trucked over to the site
from around the city. After the four buildings were meticulously re-
(inset, right) create white stripes on a black building, calling to mind the wheel of a steam train. Meanwhile, the “spokes” of the wheel are created by LED façade and on to the ground.

stored, LED cube downlights (Beta Calco) were tucked under sof-
fi ts to highlight building features and create an illuminated walkway
around each one. Simple metal refl ector heritage-style luminaires
(TMS Electrical) were also used inside and outside the buildings,
lamped with long-life, low-watt, cold-temperature cold cathode
lamps. The screw-base cold cathode lamps can be switched out
for other sources such as screw-base LED lamps, which were not
available at the time of the design.
Another centerpiece of the site is a coal and sanding tower,
which represented the only use of fl oodlighting on the project.
A steam train is displayed under the tower—”we wanted the
tower to be a bit of an attraction,” says Gottesman—and the ce-
ramic metal halide fl oodlights (elliptipar) are discreetly positioned
where the tower’s legs and underside meet. The CMH wide-beam
and vertical optics capture the details of the train for visitors.
The meticulous nature of this project extended to rigorous
mock-ups and product testing. . .weather be damned. “The mock-
ups and aiming were done a year apart in February,” says Got-
tesman. “Picture this—we’re out there by Lake Ontario and it’s
15-20 deg F. We wanted to test everything and we had about 60
Four and 9-W LED downlights tucked under the soffi ts of the historic buildings highlight the building features and create illuminated walkways around each one.

over two nights, from 6:00 p.m. to midnight, and ranged in locale
from the snow-covered ground along the façade to an 80-ft lift de-
ployed to test signage lighting above the coal and sanding tower.
The team bundled up in layers, says Gottesman, knowing there
would be “a lot of standing around and looking around.” A small
price to pay, however, for a chance to make history. ■

Change of Heart
The façade of a new Tijuana building pumps with blue and red light—an emblem of new life in a troubled city

Outfi tted with a high-end restau-
rant, an elevated running track
and an attention-grabbing, color-
changing LED façade, VIA Corpo-
rativo is hardly the type of contemporary
mixed-use building you’d expect to fi nd in
Tijuana, Mexico. And that’s precisely the
point. “People think of Tijuana and they
think drug wars,” says architect Ramón
Guillot Lapiedra, EstudioARG, Tijuana.
“We wanted to transmit something else by
creating a building that would shed a dif-
ferent light on the city and help its image;
we wanted to make a statement.”
The building’s façade lighting does just
that. Designed by Guillot Lapiedra and light-
ing designer Ron Neal of Ron Neal Lighting
Design in Carlsbad, CA, it comprises static
blue LEDs that illuminate a seven-and-
a-half-story aluminum architectural skin,
static red LEDs that light the eighth-story
roof, and color-changing LEDs that switch
between blue and red in the eight-story air
chamber that punctuates the middle of the
building’s north side.
LEDs also illuminate the adjacent
150-ft-tall concrete tower that houses
the elevators and restrooms, and is con-
nected to the main building by a 5-meter-
long bridge, as well as the building’s lobby,
which sits at the base of the tower. The
lighting not only gave the building a rec-
ognizable identity, it also helped VIA Cor-
porativo become the fi rst building in the
region to earn LEED Gold certifi cation.
BLUE SHOWS THE WAY
The Spanish word “via” translates to
“the way,” a term that inspired the design.
“The concept was based on a ‘way’ to in-
crease the quality of life for the occupants
by integrating things that would make peo-
ple comfortable, and that includes lighting.
We wanted lighting not only to be function-
al, but to inspire people,” says Neal.
Lighting also served as a way to alter
the perception of Tijuana through use
of color, specifi cally blue, a color that
connotes safety and peace, says Guillot
Lapiedra, who used blue LEDs to illumi-
nate the perforated aluminum skin that
shrouds three sides of the building.
During the day, the skin acts as an in-
sulation device that lowers the building’s
radiant heat while preserving views to the
outside. (Thermally separated, double-pane
windows further cool the building; Guillot
Lapiedra estimates that it uses only natural
ventilation for three-quarters of the year.)
The curved, wavy skin protects the build-
ing by blocking winds, including the strong
Santa Ana winds which are defl ected by the
convex portion of the skin.
At night, more than 400 blue LEDs mount-
ed on the inside edge of the scrim refl ect
onto the building’s glass-and-metal façade
and back onto the exterior aluminum skin
to transform the façade into a glowing lan-
tern. Red LED luminaires mounted outside
of the eighth-story parapet wash the un-
derside of the roof for an interesting color
contrast. (All LED façade lighting used on
the project is Philips Color Kinetics with
the exception of the blue LEDs, which were
sourced by EstudioARG.)
A HEART BEATS AT THE CORE
The north-facing side of the building—
which is exposed to less sunlight—is the
only portion of the façade not covered
by aluminum skin. For colorful nighttime
lighting on this side of the building, Neal
suggested LEDs to illuminate the air
chamber, a main artery that connects the
lower-level parking garage with the main
eight stories of commercial space above
and the adjoining concrete tower. Topped
with a low-e glass-coated skylight, the
chamber brings natural light to the offi ce
Punctuating the northern façade, an air chamber is illuminated by RGB LEDs. The magenta LEDs incorporate 50 percent of the two static façade colors—the blue that lights the architectural skins on the other three façades and the red that washes the roof overhang. Inside the chamber (left), light is refl ected off of the glass.

areas on each fl oor. What’s more, “it’s a
vein, a heart, a sculpture that helps com-
municate between all the spaces within
the building,” says Guillot Lapiedra.
Positioning the LEDs to achieve the right
effect was a challenge given the air cham-
ber’s complex shape. In the center of the
north side, the air chamber sits half out-
side, half inside the building. The outward-
facing half of the chamber is fi tted with a
perforated metal scrim inside the green-
tinted glass. On each fl oor, six LED lumi-
naires were mounted to the exterior ceiling
outside of the chamber glass “to wash the
building scrim. We knew we’d be able to
get light through that scrim onto the refl ec-
tive glass spaces within the chamber. The
light gets telegraphed into other spaces
through the refl ections,” says Neal.
Rather than adding a third color to an al-
ready bold façade, “we dialed in precisely
50 percent of the red and blue colors to
create magenta, which is an amalgam of
the roof and façade,” says Neal. Turned on
from dusk to dawn, the RGB LED luminaires
change color approximately every 15 min-
utes, shifting from red to magenta to blue.
LIGHTING THE VOID
On the opposite side of the building, the
lighting for the 150-ft-tall concrete tower
makes a different statement. “It’s a solid
structure with a void of light [to demon-
strate] the idea that ‘within a void there is
the light,’” says Guillot Lapiedra. The “void”
is represented by an eight-story recession
in one of the tower’s four sides. The nega-
tive corner was then fi lled with light, us-
ing only one high-output LED fl oodlight to
uplight the void. A warm-white color was
selected “to keep it neutral. We wanted to
distinguish that element and to identify it
as its own form, but we didn’t want to in-
troduce another color to the façade light-
ing scheme,” explains Neal.
At the base of the tower is the two-
story lobby. Here, white LEDs reveal a
colorful architectural element—translu-
cent red glass panels that line the lobby
wall. As in the air chamber, Guillot Lapie-
dra wanted the lobby panels to have an
asymmetrical shape, so randomly posi-
tioned, 10-deg LED luminaires graze the
panels from behind to create an abstract
pattern. Visible through the green-tinted
lobby doors, the interior panels are a sign
that the building’s commitment to color is
more than just skin deep. ■

sole-source listing will lead to them paying
more than they should.
While this approach seems prudent,
quite a few municipal specifi ers that I’ve
spoken with share the frustration of not
ending up with the product(s) they want-
ed, even after some comprehensive re-
search prior to issuing their RFP. It’s clear
that the three-name approach often has
the result of nullifying this research, and
the city ending up with an inferior product.
One reason for this is that it is very diffi -
cult to identify three LED luminaires that
are truly equal, particularly when it comes
to decorative street lighting.
More so than other bid items, outdoor
street lighting is a complex landscape of
variables that is very diffi cult to navigate.
While announcing the results of last year’s
Next Generation Luminaires competition
at the Strategies in Light conference, the
judges shared that next year’s competition
might not include outdoor street lighting
products, due to the inherent diffi culty in
judging that particular family of luminaires.
This diffi culty is what leads to the prob-
lem of constructing a proper RFP. What of-
ten happens is that the specifi er (municipal
employee or contract engineer) will gather
education on various LED products and
technologies. This may come from lighting
agents, other lighting specifi ers or municipal
contacts, or straight from the websites of
lighting authorities such as the Department
of Energy and/or IES. Armed with an under-
standing of LED technology, a specifi cation
begins to take shape around a product that
the specifi er feels meets their particular
needs (both performance and budgetary)
and is built and engineered appropriately.
Then, usually just before the RFP is issued,
the city will require that two more names be
When it comes to issuing an RFP, municipalities face a common challenge: how
to get the product(s) they want, while providing for fair and healthy competi-
tion that results in getting the best price. One of the more common approaches
taken by municipalities is to mandate that three names (or products) be listed
on the specifi cation or bid document. Sometimes this is mandated as part of the state or fed-
eral monies tied to the project. In other cases, the city is concerned that a one-name spec or

added to the RFP in order to satisfy its (often
unwritten) rule of a three-name spec. While
the intent is to create “equal ground” or “fair
market competition,” what the city is actu-
ally doing in far too many cases is watering
down or negating the requirements that its
specifi er spent months deciding were im-
portant. This approach to selecting an LED
fi xture fl ies in the face of the LED education
that the DOE and IES strive to put forth. This
can be particularly frustrating to the speci-
fi er, who is aware that the other products
are not what their research led them to, but
they’re unable or unwilling to “fi ght city hall.”
Once a product is listed on the RFP, the
low-bid contractor can supply it as pre-
approved, even though in many cases it
is inferior to the primary product being
specifi ed. Pointing out any inequities or
issues with the fi xtures is a moot point.
Even if the city becomes aware of these
issues, it would face a legal challenge
from the low-bid contractor and/or dis-
tributor because the product was already
listed on the legal document, i.e., the RFP.
A BETTER MOUSE TRAP
A better approach to issuing a specifi -
cation for LED street lighting is to gener-
ate a performance specifi cation, listing
no manufacturer names or catalog num-
bers. By taking this approach, you keep
the focus where it belongs, on the perfor-
mance required from the fi xture. You also
avoid the aforementioned pitfalls.
Obviously the criteria should come pri-
marily from the DOE and IES, rather than
from any one manufacturer’s literature.
When the project is being privately fund-
ed, the specifi er generally has the free-
dom to lock in on any product he selects
(within the project’s budgetary guide-
lines). However, when dealing with public
monies, the specifi er takes a signifi cant
risk by inserting verbiage into the RFP
taken directly from one product’s specs,
or building a specifi cation that is clearly
designed to disguise a sole source inten-
tion. Few specifi ers are willing to take
this risk, knowing the long-term battles
that are likely to ensue and the potential
to jeopardize their credibility on future
projects. If they take the more prudent
route suggested here, then it doesn’t mat-
ter how many manufacturers or contrac-
tors bid the job. All will truly be on equal
ground, and the city will be in a much
stronger position to get a product that will
do everything that’s expected.
Here is an example of boilerplate per-
formance criteria around which an RFP
can be built, incorporated with the spe-
cifi c requirements of an individual project.
• Lumen data should be generated per
diode testing that meets IES LM-80-08.
• IES fi les should be generated per ab-
solute photometry, as described in IES
LM-79-08. Note that the current itera-
tion of the LM-79-08 standard does not
call out the CCT, nor the drive current
of the sample tested. These should be
identifi ed. In addition, the RFP should
stipulate that the LM-79 testing was
conducted with the light engine inside
the desired style of fi xture.
• Lumen depreciation should be defi ned
in terms of IES TM-21-11. Likewise, a
minimum L70 rating should be specifi ed,
using a drive current consistent with
the drive current used for the LM-79
photometry testing.
• The desired range of acceptable CCT
should be identifi ed.
• Any LED photometric layouts or iso-
lines that are provided, must call out
the LLF that was used so that they can
be equally compared and trusted to be
realistic.
• If the municipality is converting from
high-pressure sodium, low-pressure
sodium or mercury vapor to a broad
spectrum white light source (LED,
metal halide or induction), the RFP
should specify whether or not any
photopic/scotopic multiplier may be
applied, so that everyone is competing
on an equal basis of comparison.
• Minimum luminaire effi cacy should be
specifi ed, which translates to energy
savings. This must be generated by di-
odes using the acceptable range of CCT,
and should only apply to the downward
delivered lumens actually being utilized.
Typically, uplight is considered wasted
energy that contributes to sky glow,
and should not be counted. Note also
that in many cases, effi cacy will vary
depending on the IES distribution type.
Just before the RFP is issued, the city will require that two more names be added to the RFP. While the intent is to create ‘fair market competition,’ what the city is actually doing is watering down or negating the specifier’s requirements, which took months to develop

STREETL IGHT SPEC
48 September 2011 | LD+A www.ies.org
• When relevant, as in the case of a
decorative fi xture, acceptable and/or
unacceptable lens styles should be
specifi ed. You want to avoid achieving
higher delivered lumens at the cost of
higher glare and may prefer an opaque
or diffuse lens.
• Any/all required uniformity ratios should
be clearly stated, and the municipality
should be prepared to provide prospec-
tive bidders with an AutoCAD fi le of the
streetscape so that proper layouts can
be provided for review and comparison.
• Minimum warranty terms should be
specifi ed that include both the LED ar-
ray and the driver. In addition, the RFP
should require any bidders to clarify
what triggers their warranty.
• The driver should be UL or ETL recog-
nized, and minimum driver effi ciency
should be specifi ed.
• The RFP should specify a minimum lu-
minaire surge protection level, such as
IEEE/ANSI C62.41.2.
If the RFP is structured around perfor-
mance criteria in this way, then there is no
need to require three names, or even to
list any specifi c luminaire. The document
can include a simple line drawing or pho-
tograph in order to identify the desired
style or design. In addition, the RFP can
descriptively identify the preferred de-
sign style (suspended, four-sided lantern;
post-top, six-sided lantern; cobra-head
luminaire; shoe-box style, etc).
Another measure that can be taken in
order to confi rm the quality of the low-bid
fi xture is to require three or four samples
for mockup, so that less tangible variables
can be reviewed for any red fl ags. These
might include ease of access to the LED
array and/or driver in the case of main-
tenance or an upgrade; reviewing the
sturdiness of hinges or other hardware;
reviewing the quality of castings, specifi c
aluminum alloys, and/or the paint fi nish.
Understandably, some federal and
state grants may mandate the three-
name approach. But as LED technology
and new adaptive controls permeate the
lighting market, hopefully that approach
will shift and allow all of us to approach
the bid process in a more effective way.
As a secondary benefi t, the adoption of
performance specifi cations like this will
entice manufacturers to design and engi-
neer their luminaires to a higher standard,
making more effi cient and cost-effective
options available in the marketplace. ■

50 September 2011 | LD+A www.ies.org
The Integrated Design Labs at the
University of Washington in Seattle
and University of Idaho in Boise in
partnership with New Buildings In-
stitute have developed a free web-based
design resource for the implementation
of proven daylighting design strategies in
commercial buildings. The Daylighting Pat-
tern Guide (http://patternguide.advanced-
buildings.net/ ) provides building designers,
owners and students a platform to explore
the relationships between sky, site, build-
ing aperture and space planning. This
interactive resource uses a combination
of real-world built examples, including of-
fi ces, schools, libraries, laboratories, mu-
seums and industrial facilities (Figure 1),
and advanced simulation to set the stage
for substantial reductions in lighting power
density and overall building energy use.
Over the past decade the Integrated
Design Labs have provided daylighting de-
sign and technical assistance to architects,
engineers and lighting designers in the Pa-
cifi c Northwest and nationally. Much of this
work has been funded by the Northwest
Energy Effi ciency Alliance as part of a com-
mercial building conservation program. This
practice has revealed recurrent themes,
key variables and architectural principles,
which were demonstrated by daylit spaces
that had proven to be successful over time.
Building upon this knowledge, we have built
a series of daylighting patterns that identify
and visually represent these successes and
lessons-learned in an intuitive and visually
oriented online resource. The Guide illus-
trates successful daylighting design pat-
terns by placing an emphasis on creating
visually comfortable spaces because our
experience suggests this will help ensure
that that occupants accept energy-effi cien-
cy measures associated with daylight such
as automated electric lighting controls.
A recent study by the Heschong Mahone
Group revealed that less than 25 percent of
the predicted energy savings are realized in
spaces with daylight delivered from the side
(Heschong et al., 2005). Even more reveal-
ing is that more than 70 percent of the rea-
sons identifi ed for failure relate directly to a
lack of human satisfaction with the overall
daylight performance, with less than 30
percent explained by failures due to hard-
ware components. This follows our experi-
ence, which suggests that poor daylighting
performance stems primarily from the fact
that many spaces with daylight fail to meet
the visual satisfaction expectations of oc-
cupants either due to insuffi cient daylight,
imbalanced distribution of daylight, or chal-
lenges maintaining visual comfort with such
a highly variable light source.
As a starting point, we developed a
list of daylighting design strategies and
principles and prioritized the most critical

variables to overall daylighting success.
We then developed a matrix including
daylighting design variables and possible
design approaches or “daylighting pat-
terns.” We contacted daylighting experts
from around the country to supply candi-
date buildings for site visits and inclusion
in the Guide. Site visits consisted of col-
lecting illuminance and luminance data
of the spaces of interest. High Dynamic
Range (HDR) photography techniques
were used to document the luminous con-
ditions of the spaces and were later used
to create luminance maps of the scenes.
Next, digital models were created us-
ing site measurements, photography and
architectural drawings. These models
were processed in the Radiance simula-
tion program where detailed rendering
parameters and material properties were
input. Rendering cameras were specifi ed
to match the fi eld of view of the photo-
graphed space. Then a simplifi ed accura-
cy check was conducted on the Radiance
simulations using the HDR photographs of
the built spaces to fi ne tune material prop-
erties and simulation parameters.
After the as-built simulations were fi -
nalized, a series of test conditions were
developed in order to explore successful
and unsuccessful compositions of day-
light distribution. These test conditions
were choreographed into a series of “pat-
tern steps” (Figure 2) that combine to
make up an individual pattern sequence il-
lustrating an important daylighting design
variable. This allows us to demonstrate
the relationships between good built ex-
amples of daylit space, the information
generated by design tools and the kind of
“rule of thumb” guidelines that designers
commonly apply. We felt that beginning
with successful built spaces was critical
to support meaningful interpretation and
increase confi dence in the results. Our
highest priority was given to qualitative
data, essentially via color renderings,
with supporting quantitative data such as
luminance distribution diagrams.
In order to support navigation, an instru-
mented dashboard indicates simulation
parameters for time of day, time of year and
sky condition. A consistent key was made
for illumination plots, and the percent of
fl oor area that achieved a specifi ed illumi-
nation criterion is called out for each pat-
tern step. A “fi lmstrip” reveals the different
geometric variables explored throughout a
given pattern and is commonly illustrated
with architectural section icons and occa-
sionally other widgets.
Four of the 19 patterns in the Guide are
outlined here to provide an introduction to
the content available in the online resource.
EXHIBITS A-D
Pattern A-Work Station Partitions: This
pattern sequence (Figure 3) is based on
the Banner Bank Building in Boise, ID. It
includes a 40 percent window-to-exterior
wall ratio with a window head height at 9 ft,
6 in., a sill height at 3 ft and a ceiling height
at 10 ft. Interior refl ectances are roughly
80 percent-50 percent-20 percent for ceil-
ing, walls and fl oors, respectively. The pat-
tern reveals the signifi cant interaction be-
tween daylight penetration from perimeter
glazing and interior offi ce furniture design.
The selection and design of open offi ce fur-
niture, especially workstation partitions,
requires care to ensure the preservation
of daylight and views. Even in the most
carefully considered daylighting solutions,
effective workstation design can be the
difference between realizing daylighting
goals and unintentionally compromising
design intentions. This pattern illustrates
the challenges associated with providing

THE AUTHORSdaylight from one side when interior fur-
niture partitions exceed 42 in. parallel to
daylight glazing.
Pattern B-Glass Area Ratios: This pat-
tern (Figure 4) is based upon NBBJ Ar-
chitects’ New York City offi ce space at
2 Rector Street. The pattern sequence
highlights the implications of different
degrees of glass-to-wall area ratios (20
percent, 26 percent, and 30 percent) while
also revealing the effect of glazing located
on one, two and three sides. The pattern
demonstrates how important it is to have
daylight from multiple sides and how one
can provide substantial daylight using a 30
percent glazing-to-wall area ratio as long
as windows are provided on multiple sides.
Pattern C-Blinds and Shades: Blinds
and shades provide a range of methods
to control direct sunlight and redirect
diffuse daylight (Figure 5). Assuming a
reasonable relationship between section
depth and window head height (does not
exceed 2:1), suffi cient daylight can be
provided by windows on just one side of
a space. However, blind systems and their
use (or lack of use) by occupants can be
the single largest determinate of realized
daylight performance in many building
types. This pattern examines multiple
blind types and positions given various
weather conditions to illustrate an often
overlooked, but absolutely critical aspect
of effective daylighting design. While
fi xed external shading can provide signifi -
cant benefi ts, it is rare that glare control
can be entirely solved without some form
of blinds or internal shades.
Poor design that results in blind closure
for long periods can make an otherwise
well-daylit space virtually non-daylit.
Specifi cally, this pattern illustrates that
inadvertently leaving blinds deployed
during an overcast day results in only 21
percent of the space as “daylit” whereas
on a sunny day, 89 percent of the space
is “daylit” with the blinds deployed at
the same position. To solve this problem,
some buildings incorporate automated
roller shades or louver blinds. This allows
blinds to be adjusted based on time of day
or sky condition or simply repositioned
open after a preset time.
The case study example used here is the
Genzyme Building at 500 Kendall Street in
Cambridge, MA, designed by Behnisch
Architekten. It is important to note that
the Genzyme building uses automated
motorized daylight enhancing blinds with
weather station and astronomic time
clock control and allows for user over-
rides of the system. However, to illustrate
important points about blinds use, several
other types of blinds and blind control as-
sumptions are included.
Pattern D-Toplighting (Small Building):
This pattern provides a model for effec-
tive daylighting design in small-scale, sin-
gle-story commercial construction. This
building type constitutes the vast major-
ity of new and existing buildings in North
America. These buildings represent a
tremendous daylighting opportunity—
which is applicable to retail, offi ce, light
industrial and other small-scale building

typologies—through the use of skylights
and vertical glazing. This is primarily be-
cause the entire fl oor plate, regardless
of orientation or section depth, has day-
light access from overhead. In this case
(Figure 6), we explore a range of skylight
distributions, transparent vs. diffusing
skylight glazing, the inclusion of view
windows and the role of wall-washing
skylights.
This case study example is the IDeAs
Offi ce Building in San Jose, CA, designed
by the EHDD Architecture and Integrated
Design Associates (IDeAs). The building
is a renovation of an existing single-story
retail bank building. Through the use of
daylighting, along with an innovative me-
chanical system and rooftop photovoltaic
panels, the IDeAs offi ce building achieves
net-zero energy use on an annual basis.
THE GUIDE’S GOOD INTENTIONS
Our intention with the Daylighting Pat-
tern Guide is to provide a resource that
designers can consult to generate ideas
for initial concept design and to show-
case the range of critical considerations
inherent in a broad range of daylighting
designs. By beginning with existing highly
regarded daylighting projects we provide
both a level of “proof of concept” and a
measure of real-world feasibility. We
hope that the Guide will be informative to
design teams as they work with owners
and users in making the case for daylight
illuminated buildings. The Guide can also
be useful in promoting collaboration and
discussion about possible design alterna-
tives among architects, engineers, light-
ing designers and interior designers. We
also think the Guide will be useful to stu-
dents exploring daylighting alternatives
in architectural studios.
The Guide cannot be a replacement for
the rigorous testing of specifi c design
ideas—in fact we consider the appropri-
ate use of simulation tools to be critical
to effective daylighting design. We do
however feel that by illustrating high-per-
formance daylit buildings and the design
iterations possible within their typologi-
cal context, that designers might begin
at a point closer to a successful daylight-
ing outcome and that any simulation time
and effort will be applied toward the most
meaningful lines of design inquiry. ■

SUSTAINABILITY & ECONOMICS
In an age when the hot topic is
decreasing our impact on the earth, how
do sustainable design solutions impact
the economics of the client, the region
and the nation? Sustainability fi rst costs
can be an overwhelming obstacle—but
can the economics work to encourage
sustainability pursuits beyond simply
achieving the feel-good label of “Friend
of the Environment”? See the discus-
sion unfold as our experts describe the
extreme considerations and present a
balanced business case for the econom-
ics of sustainability.
ARCHITECT & ENGINEER
The two disciplines work together
all the time, but how do they really feel
about the needs of one another? Is the
siting and fenestration of the building
more important than the lighting and
energy impacts the site and windows
yield? Integrated teams are standard
today, but the question actually is
whether or not there is a best-case solu-
tion to a balanced approach to daylight,
electric light and energy consumption.
The experts will provide you with facts
and opinions for consideration as you
embark on your next integrated design.
Monday, October 31
Sparring SpeakersThere are fl ashpoint topics in the
lighting industry that provoke strong
feelings on both sides. During four
separate 90-minute “sparring sessions,”
our combatants will be asked to argue
the “extreme” side of their respective
topics . . . but then come to a meeting of
the minds at the close of the session and
offer a joint solution. The four topics and
sparring partners are:
HEALTH & ENERGY
Usually the debate over which lighting
technology to use comes down to quality
and watts per sq ft, but does anyone ever
think about how the technologies affect
the health and well-being of humankind?
Is the use of energy-saving technolo-
gies more important than decreasing the
harmful effects of energy saving tech-
nologies on people? Can the two ideals be
integrated into one lighting solution?
EDUCATION & ENERGY
Educational facilities today are a
magnet for trying out sustainable design
features and practices. But what is the
impact to the educational environment
and its purpose when watts per sq ft
is the primary consideration of codes
and standards? These positions can be
worlds apart, so sit down, pull out your
pencils and fi nd out if our experts can fi nd
a common ground.
Of Sparring and Sketching
The structure of the 2011 IES Annual Conference, “Lessons in Sketching: From Mas-
ter Classes to Global Lighting Solutions,” is designed to help every attendee learn the
benefi ts of sketching—the idea of getting something on to paper that you may simply
be mulling in your head. At fi rst, attendees will watch how experts resolve technical
confl icts and fi nd solutions, but as the conference progresses, they will be challenged to
think independently and develop (and sketch) their own solutions and ideas.

Arrive in Austin a little bit early, or carve out
some time post-conference to see the best of both
lighting design and art at Arthouse. The lighting
design by Nelson Jenkins, Lumen Architecture,
captured a 2011 Lumen Award of Excellence from
the IES New York City Section and an IES Illumination Award of Merit.
Both a theater and department store in previous incarnations, Art-
house blurs any distinction between art and architecture. Its lighting
dazzles and embraces modernity through light and form. Despite a tight
budget and strict energy allowances, Jenkins and his team focused on cre-
ating functionality and strong visual elements. The signature architectural
components are the building walls, now artistically punctured by LED illu-
minated green glass blocks that accentuate the interior and exterior during
both the day and at night.
If You Have Time...
Sketch as You GoThe one constant throughout the
three-day event will be the sketchpad.
Every attendee will receive a sketch-
book with their registration and are
encouraged to “sketch as they go”
during the various sessions and IES
Illumination Awards presentation. Bring
crayons, colored pens, colored pencils,
watercolors—whatever helps your
brain work best—and don’t feel that
these sketches are limited to drawings
(doodles, notes and other visual expres-
sions of ideas are equally valuable).
There will be scanners in the circula-
tion areas of the conference so attend-
ees can scan their sketchbook pages to
share them with other attendees. There
will be prizes for participation, and a
PowerPoint presentation will display
this grab bag of sketches during the
Gala dinner on Tuesday evening.
Monday, October 31
Research AppliedOftentimes, when practitioners attend presentations on lighting research, they sit
there listening attentively but leave the room asking what does it mean for me and my
everyday design work?
Ask no longer: Four “Research Applied” sessions will consist of researchers (who
will discuss key fi ndings on a specifi c lighting topic) paired with an “application special-
ist” (who will discuss how these fi ndings can be translated into design solutions for
a real-world project). The structure of these sessions represents a new format for
researchers at the IES Annual Conference and is meant to help both the research and
design communities gain a better understanding of the other.
Leading off the “Research Applied“ sessions will be Prof. Ron Gibbons, Virginia Tech
University, and lighting designer Nancy Clanton, Clanton Associates, who will pres-
ent on how LED sources measure up against high-pressure sodium and low-pressure
sodium on roadways in three U.S. cities: Anchorage, AK, San Diego and San Jose, CA.
The evaluation of each lighting system considered both public acceptance and driver
visual performance.
Tuesday, November 1
FuturecastingThe educational program closes on the afternoon of November 1
with a “futurecasting” presentation by Hans-Peter Loock, a profes-
sor of chemistry at Queen’s University, Kingston, Canada, who will
discuss the development of a fi ber-optic guitar—and other instru-
ments such as a violin and cello—to record sound. What does this
mean to the future of lighting design? If we can really use light to create music, what
other non-visual, sensory, applications might be possible?

One is the magic number for Glen Cove,
NY—in just one month, a one-for-one
lighting replacement with a roughly
one-year payback made one big impact on the
city’s Brewster Street Parking Garage. Tired of
sending maintenance crews out to relamp the
three-story garage’s 100-W high-pressure so-
dium fi xtures, the city selected LED luminaires
from RAB Lighting to replace the existing 264
fi xtures, which operate 24/7.
The luminaires’ light engines have a 50,000
hour-rated lifetime and are expected to provide
fi ve to six years of maintenance-free operation.
Each luminaire features two 13-W LED light en-
gines, for a total of 26 watts, a 77 percent reduc-
tion in energy compared to the previous HPS
fi xtures. Based on energy savings alone, the city
expects to use 240,000 kWh less and save more
than $46,000 per year. What’s more, it received
a $250 energy-effi ciency rebate per fi xture from
local utility Long Island Power Authority that off-
set $68,000 of the initial project cost.
Beyond energy and maintenance savings, the
new luminaires “delivered a much brighter and
whiter light to the parking garage than the previ-
ous technology,” says Glen Cove mayor, Ralph
Suozzi. The 5,000K color temperature light
“helps improve people’s sense of security [be-
cause] they have higher visual acuity with the
cooler light,” explains Nathan Drucker, applica-
tions engineering manager for RAB Lighting.
While the 2,128-lumen LED luminaires techni-
cally deliver fewer lumens than the HPS lights,
their fully shielded, full-cutoff design “directs
light where we want it,” says Drucker. “The
mounting height was ideal for the performance
characteristics of the fi xture, as opposed to fi x-
tures with an uncontrolled uplight component
that throw light all over.”Elizabeth Hall
The Challenge: Reduce lighting energy use and maintenance in a 24/7 park-ing garage

“The Handbook is the most thorough and comprehensive revision in the past forty years. Not only is the format completely new, but the scope and depth of the subjects are unprecedented. This new edition is both an authoritative source of data and an eloquent explanation of the ‘how’ and ‘why’ of the IES recommendations. It is quite simply the best Handbook ever.”

September1973
» Up in the Air : The main article in this wide-ranging theme issue on “air-
ports, aeronautics and astronautics” was a comprehensive eight-page
story on the new $250 million Kansas City International Airport. “By 1980,
the airport is expected to handle 10 million passengers and 800 million
tons of cargo a year.” The article dissected the indoor and outdoor lighting
used for the parking lots, roadways and terminal, all the way down to the
aircraft parking apron. Outdoor fi xtures on the market at that time were
not viable for the project, so custom units fi tted with mercury lamps were
installed on the roads and parking lots. Mercury vapor fi xtures were also
deployed on parking lot stairways and walkways. The centerpiece of the
project, though, was the 6,000 custom rectangular luminaires enclosed in
coffers that were used to highlight the terminal’s roof structure and fl ood
the building with light. Metal halide lamps (175-W) were the solution here.
» Incandescent on the Ropes : For all of today’s nostalgic talk of “Edison’s
miracle,” lighting professionals were phasing out the incandescent
bulb as far back as 1973. The article “Relighting a Hangar”—one of the
aeronautic theme stories in this issue—described how the Minnesota
Air National Guard’s maintenance hangar transitioned from a 5-10 foot-
candle mercury and incandescent system to a 1,000-W high-pressure
sodium layout offering 100-plus fc using the same grid spacing.
LD+A’s “In Focus” section chronicled the relighting of the 570-ft-
high San Jacinto Monument (“the world’s tallest masonry column”). An
“obsolete pole-mounted incandescent layout” was jettisoned in favor
of metal halide fl oodlighting to accentuate the spire’s fossilized buff
limestone surface.
» Homespun Yarn : What’s true in 2011 was true in 1973: Home builders
often don’t give lighting enough attention. Hoping to remedy this, mem-
bers of the IES Residence Lighting Committee traveled to Atlanta, GA, to
exchange ideas with home builders and Georgia Power Co. personnel.
Each of the three builders requested “comments and criticism” from
committee members concerning the lighting used in their respective
projects. One builder remarked, “Today, I suddenly discovered there is a
whole group of people who specialize in this fi eld.”
