projects start….

Save Money - Electricity and Maintenance

Metal Halide

• 175 watt, 215 w total draw

• 15,000 hours rated lamp life– Less than TWO years

• $30 per lamp

Vapor-tight Fluorescent

• 104 watt total draw

• 45,000 hour rated lamp life– Nearly FIVE years

• $4 per lamp

50+% reduction in electricity costs

60+% fewer lamp replacements

75% reduction in total maintenance costs

With utility incentives project payback can be less than

two years, in some instances

Improve Safety

A well-lighted environment dramatically reduces the potential of liability from incidents of

crime or injury

• Improvements to lighting color, quality and uniformity

….the security guards were thrilled.

Illumination Guidelines

• IES Recommended Minimums for Parking Areas (RP-20-14)– Minimum of 1 foot-candle everywhere (on the floor)

– Maximum / Minimum Uniformity ratio of 10:1

– Previous Recommended Practice included designing average illuminance to greater than 5.0 f.c.

• Recommended Practice for High Security Areas have increased foot-candle recommendations– 6.0 f.c. average, 2.0 f.c. everywhere

Is a parking garage a place where we

should care about safety and security?

• Uplight - avoid the “cave effect”

• Uniformity - even distribution of light throughout

• Color – closer to daylight

Technology Differences

FLUORESCENT TECHNOLOGYFluorescents

• Lowest initial cost and best long-term total cost of ownership of the primary technologies

• Good light distribution with quality products

• Maintenance is cheap and easy

• Long lamp and fixture life

• Quality of components and build can be an issue, leading to loss of vapor-tight seal

• Is there an uplight contribution?

LED TECHNOLOGYLEDs

• Efficient, but still quite costly on a per lumen basis

• Illumination performance is a mixed bag across designs

• Relatively newer technology with multiple points of catastrophic failure

• Most designs are “rip-and-replace” at end of rated life leading to poor total cost of ownership, despite short paybacks

• Glare can be problematic

• Reliability is questionable in less expensive fixtures

“Surprisingly to many, the true reliability and lifetime of light-emitting

diode (LED) lighting systems is generally not known.”DOE Report: LED Luminaire Lifetime

June 2011 Introduction

Induction

• Many great characteristics– Energy consumption, lamp life, color

• Still high initial costs

• Light levels are too low, so higher wattages are required in typical garage lighting layouts

• Non-dimmable, limited options

• Some imported fixtures are of low quality

• Questionable long-term market viability of the technology

Five key questions for fixture selection

Does it have enough lumen output to meet IES recommended minimums?

Does it have uplight to illuminate the entire garage, including vertically?

Is it low glare so that driver temporary blindness isn’t an issue?

Does it have good light distribution and uniformity?

Is it field-serviceable?

Keep in mind…

• Lumens, not watts

• What’s cool, is not warm

• Cheap can be expensive

• Light is everywhere, not just on the floor

Are you getting what you’re paying for?

“LED Luminaire Reliability”

“An LED luminaire manufactured

in a manner that cannot be

repaired in the field will “fail” upon

failure of any part (drivers, engine,

optics, chips or wiring cables) and

will require complete replacement

which is contrary to current

expectations about lighting.” DOE Report: LED Luminaire Lifetime , p.12

Make It Happen

How to get it right – Re-lighting Richmond

• Utilized existing layout to reduce installation costs

• White-painted walls allow for “light bounce”

• Illumination doubled in most areas, eliminating dark zones

• More than 40% in electricity savings

7th & Marshall – Existing Conditions

• Older garage with 70 watt High Pressure Sodium fixtures– Dark, unappealing color

– Three-across layout

– Tremendous maintenance costs for lamps, ballasts, and lenses.

The City worked with Standard

Parking, the City’s parking

management company, to identify

potential vendors with a track

record and proven technologies

7th & Marshall – Results

• Utilized existing layout to reduce installation costs

• White-painted walls allow for “light bounce”

• Illumination doubled in most areas, eliminating dark zones

• More than 40% in electricity savings

A Checklist

Make sure…

See them “in the Wild”, not on the computer

Know your why

An investment for now and the future

Actual results, not technology, is the priority

The after has to look better than the before

Good lighting is a long-term investment

A clean, well-lighted garage is safer, more cost-effective, and more appealing to customers.
