The International Code Council’s Steve Thorsell presented a program on the new IgCC which publishes in March. This new code is the first attempt at stating green construction requirements in mandatory language rather than options.

“The IgCC Code objective is to reduce the negative impacts of the built environment on the natural environment. The approach means

more predictable results than rating systems,” stated ICC-ES’s Thorsell. The code covers a full range of sustainability topics including: Natural Resource Preservation; Material Conservation; Energy Conservation; Water Conservation; and Indoor Environmental Quality.

The code, once adapted by a municipality, is consistent with the ICC Family of Codes and is intended to be primarily enforced by building officials as an “overlay” code. All other building codes as well as structural and other codes still apply. The Green Code adds requirements that make the building “greener,” and go “beyond code minimums.”

The code is intended for private and government buildings raising the sustainability for all commercial buildings. “This positions the IgCC to achieve environmental benefits on a massive scale…not possible with voluntary rating systems,” said Thorsell.

Chapters of the code deal with sustainability topics and require choices to be made by the jurisdiction and the building owner/registered design professional.

New International Green Construction Code (IgCC) PrimerIn roofing, that means insulation R-values jump 30% from

existing 2012 IECC Code requirements in Illinois of R-25 to about an R-33. Chapter 5, Material Resource Conservation and Efficiency mentions that there must be a material and waste management plan.

The code states that 50% of construction waste diversion is the minimum bar, with options to increase to 65% or 75%. Secondly, 55% of total materials used on projects must consist of: Used; - Recycled; Bio-based; and Indigenous Materials.

There are also regulations for mercury limits in fluorescent lamps and moisture control.

Chapter 6, Energy Conservation & Atmospheric Quality, applies to new buildings and additions to existing buildings, offering both a prescriptive and performance path to compliance.

A new term, Zero Energy Performance Index (zEPI), has been defined in this chapter. The zEPI sets an average benchmark metric for efficiency/performance of buildings at year 2000 with similar occupancy operation schedule and climate.

Chapter 7 requires and encourages the conservation of water used indoors, outdoors and in wastewater conveyance. “Chapter 7 encourages use of lower quality water whenever possible.”

Chapter 8’s Indoor Environmental Quality and Comfort brings requirements for a “management plan” for building construction, features, operations and maintenance facilitation, HVAC systems, pollution control and restrictions on prohibited materials.

Chapter 9’s Commissioning, Operations and Maintenance was a big debate during the IgCC Code development process. The Commissioning follows the special inspection criteria in Chapter 17 of the International Building Code and

CRCA’s 2012 Roofing Industry Kickoff Breakfast brought industry leaders such as CRCA’s Rod Petrick, NRCA’s Mark Graham and Hendrick Phillips’ Stephen Phillips to a packed house, setting the tone for another big show.

Phillips, the legal consultant to the National Roofing Legal Resource Center, presented AIA’s B141-1997 document that states that “The architect shall review laws, codes and regulations applicable to the architect’s services….and respond in the design…to requirements imposed by government authorities having jurisdiction (AHJ).”

A201-2007 states the “architect...incorporate into the Construction Docu-ments the design requirements of AHJ.” However, A201-2007 also states that the contractor has “visited the site, become familiar,” “and corre-lated personal observations with requirements of the Contract Documents.”

It also states in 3.2.3 that the contractor is not required to ascertain that the contract documents are in accordance with applicable laws, statutes, ordinances, codes, rules and regula-tions, or lawful orders of public authorities, but the contrac-

tor shall promptly report to the architect any nonconformity discovered by or made known to the contractor as a request for information in such form as the architect may require.

While the A201-2007 document points liability to the contractor, case law has shown that the contractor may not

be liable for code violations where it is working to architect-prepared construc-tion documents.

All this points out that code compli-ance takes place when construction docu-ments are prepared by registered design professionals. This is most applicable during new construction.

However, where the contractor is working directly with a building owner, the case may be different. Visit your personal

attorney for clarifications to protect yourself from liability. For Mark Graham’s portion of the presentation, see the

article about his program in this publication. Attendees came from Chicagoland, Illinois, Indiana, Iowa,

Michigan, Wisconsin and more to take part in CRCA’s yearly event. Watch www.crca.org for 2013’s CRCA Trade Show & Seminars programs. n

Some communities require above R-25 Insulation. Cities close to O’Hare or Midway Airports may require higher R-values for the sound transmission characteristics of the insulation. Some communities require close to R-30.

CRCA has submitted a comment to the state of IL to bring relief to the building owners and managers in reroofing situations. We’ve requested that the R-value remain at R-20 for these projects.

Why? According to NRCA’s Project Pinpoint, roofs last around

17 years. In 1995, the R-value required was about R-15. It is conceivable that a roof installed in the late 1980s, early 1990s, is going to need reroofing soon. That means the existing roof insulation of R-10-15 increases to R-25 due to the new code. That means adding 2-1/2 – 3 in. of new insulation. The additional insulation means thicker perimeter wood nailers, raising HVAC units, access doors and hatches, skylights and windows to accommodate minimum flashing heights. Older buildings typically don’t have the extra available flashing heights to accommodate that increase in insulation thickness.

CRCA believes building owners and managers will be shocked by the extra cost to install that much insulation. As a result, they may choose to not reroof, but rather patch continuously. This would negate the intent of the energy conservation code…to save energy.

Mark Graham reported key points from the new 2012 I-Codes (see page C 8).

Anyone can submit a code change proposal. CRCA is participating to affect change at the national level because building departments are deferring to the “nationally developed” code. Watch CRCA.org for reports on how we do at the Committee Action Hearings in May. n



CRCA heard from many building officials in Illinois, “to change code get involved at the International Code Council Hearings so we don’t have to amend a national publication.”

NRCA’s Mark Graham and CRCA’s Bill McHugh have attended several International Code Council Hearings to participate in the hearings that result in the published code. CRCA welcomed Mark to CRCA’s Trade Show & Seminars and he delivered a roofing summary of the 2012 International Codes (I-Codes).

“Illinois is a home rule state. Local municipalities review their building code periodically and adapt versions of the International Family of Codes,” stated Graham, NRCA’s Associate Director of Technical Services. Most of Illinois uses the 2006 or 2009 versions of the I-Codes.

For CRCA members, the International Building, Residential, Energy, Fire and Plumbing Codes affect what building owners and managers demand for new construction and reroofing. Chapter 15 of the International Building Code sets mandatory minimum requirements for and is titled, “Roofing and Rooftop Structures.”

In Illinois, the State is in the process of adapting the 2012 International Energy Conservation Code (IECC). This will affect the amount of roofing insulation required in both new construction and reroofing situations.

The current 2009 IECC requires R-20 insulation on commercial building occupancy roofs. The 2012 Code jumps to R-25. The State of Illinois passed a law mandating that 12 months after the ICC publishes a new version of the IECC, it becomes State Law. ICC published the 2012 IECC June 1, 2011. Therefore, roofing projects permitted after June 1, 2012, will have to comply with 2012 IECC unless something changes during the adoption process in the next few months.

Roofing Building and Energy Codes are Changing

Reflective roofs, ballasted and garden/vegeta-tive roofs meet Chicago’s 2009 Energy Code.

commissioning criteria found in the International Energy Conservation Code.

At this point, the building official is charged only with verifying that the special inspection or commissioning reports have been provided to the building owner. The building official is not responsible for report review and approval. Also, post-occupancy reporting may be mandated as a “jurisdictional choice.”

ASTM and other organizations are currently debating the minimum certifications, knowledge and experience required to become a commissioning agency or commissioning inspector.

Chapter 10 has provisions for existing buildings similar to Chapter 34 of the International Building Code while Chapter 11 deals with existing building site development. This is a new concept in the code, as it addresses building landscaping, site hardscape and surface vehicle parking.

Chapter 12 covers referenced standards with appendices finishing the document and is adapted by jurisdictions or projects to suit local needs.

A “jurisdictional requirement” is a mandatory requirement under the IgCC at adoption of the code. “Project electives” en-courage implementation of green practices which are difficult or impossible to mandate (e.g., brownfield remediation). This allows building owners and designers a degree of flexibility.

The new International Green Construction Code is coming. While at the IgCC Final Action Hearings in Phoenix last year, we heard many major jurisdictions adapting the IgCC Code either optionally or as mandatory. Even if it is not adapted by local jurisdictions, green code concepts will most likely appear in specifications as “best practices” for green construction.

Regardless of adoption by local jurisdictions, the IgCC Green Code has impact for the design, construction and building owner and manager community for the complete building life cycle. n

Fire Classifications – Roof Assemblies shall be tested in accordance with ASTM E 108 or UL 790. Typically, a class C or B is acceptable by the I-Codes.

Edge Metal Flashings … shall be designed and installed for wind load for resistance in accordance with … ANSI/SPRI ES-1, Test Methods RE-1, 2, 3…with wind speed determined from Figure 1609A, B, C… this means that even shop fabricated sheet metal must be test proven to resist the wind speeds as published.

Vegetative Roofs – in the last code development cycle several proposals from the national association of State fire Marshals (naSfM) brought new rules for roof gardens and landscaped roofs.

In Chapter 15, structural fire resistance for roofs topped with roof gardens shall be in accordance with table 601…reflecting the roof as possibly greater risk with this overburden and surfacing.

In the Fire Code, rooftop gardens are to be no larger than 15,625 sq ft, with max. dimension of 125 ft in length or width. A minimum 6-ft width of ASTM E 108 or UL 790 Class A Rated roof system shall separate adjacent roof gardens and separate combustible surfaces and the building perimeter.

Most important, the new i-fire code regulations require that supplemental irrigation to maintain hydration levels to keep green roof plants alive and dry foliage to a minimum. Dead foliage shall be removed at regular intervals, no less than twice per year. The fire code official may require a maintenance plan for vegetation placed on roofs due to size, materials used, or fire hazard. plus, standpipes are now required to be extended to the roof level where the vegetative covered rooftop garden is located.

Rooftop Photovoltaic Panels - energy harvesting of the rooftop continues with photovoltaic panels starting to be installed on rooftops. the naSfM also submitted proposals to develop code language regulating these rooftop accessories.

Fire classifications of panels need to meet testing required for the roof system. Wind resistance must also be demonstrated through testing of the system. Structural

Chicago’s City Hall was the first high-profile vegetative roof.

fire resistance refers the user back to Table 601. And, construction permits are required to install or modify a solar photovoltaic power system. Labels on the panels are also required on interior and exterior DC conduit, enclosures, raceways, cable assemblies, junction boxes, combiner boxes and disconnects; “warning: photovoltaic power Source”. this helps the fire department identify pv systems disconnects and components obviously and intuitively during an emergency or fire event.

Roof Surface Reflectivity – the city of chicago requires reflective roof surfaces to reduce rooftop temperatures in summer providing the city with urban heat island effect relief. roof surfaces need to have a reflectivity of either .72 new or .55 aged after 3 years. alternatively, roof system weight of 15 lb/sq ft also meets the Chicago Energy Code under an exception. consult the 2009 chicago energy code for complete details and applicability. the 2012 i-codes do not require a reflectivity value in northern climates.

another new requirement is IECC Chapter 4’s Air Barrier Requirement for the building envelope. the good news is that to comply, many common materials qualify as air barriers. Built up roof, fully adhered single ply, modified bitumen materials all are listed by name in the code as air barriers. consult the code for specifics.

International Building Code Steep Slope Ice Barriers in Reroofing - in Section 1510.3, a new 2012 exception for reroofing states…where the existing roof assembly includes an ice barrier membrane that is adhered to the roof deck, the existing ice barrier membrane shall be permitted to remain in place and covered with an additional layer of ice barrier membrane… this allows contractors to leave the ice barrier membranes which do not come off and add another layer.

Photovoltaic Panels – Residential structures shall be designed so that each array is no greater than 150 ft x 150 ft. there is a lot more about roof shape and layout of panels to allow safe access to the roof for firefighters to cut into attics during firefighting operations. refer to section 605 of the 2012 international fire code for complete information. n

Thanks to NRCA’s Mark Graham for this summary.

INTERNA LEAK DETECTION

EAGLE VIEW TECHNOL



The U.S. Dept. of Energy’s Roofing Science Program Manager Andre Desjarlais brought new research about building energy use being large and growing. He presented stats that 40% of the U.S. primary energy consumption and 39% of U.S. carbon emissions come from buildings. Buildings use 73% of U.S. electricity, 34% of natural gas directly for operations. Of the big consumers of energy, building usage is growing fastest.

In 2011, the DOE’s key tasks and milestones included a Field Study on Attic performance, hot climate roof and attic design guidelines, advances in “cool roof” technologies, impacts of radiant barrier systems, and photovoltaic roof integrations.

The “cool roof roadmap” is an upcoming project that DOE is working on, including study at building, urban and global levels. The draft can be found at www.eereblogs.energy.gov/buildingenvelope .

At the “building level,” DOE has assembled a cool roof selection guide, calculator, and a cool roof policy. Upcoming work includes an aged cool roof rating protocol and testing of advanced materials for cooling roofs off.

The cool roof policy advocates cool roofs and also high insulation values, unless not economical based on life-cycle costing. The policy includes the following directives:

• A low-sloped roof (pitch less than or equal to 2:12) must be designed and installed with a minimum 3-year aged solar reflectance of 0.55 and a minimum 3-year aged thermal emittance of 0.75 in accordance with the Cool Roof Rating Council program, or with a minimum 3-year aged solar reflectance Index (SRI) of 64 in accordance with ASTM Standard E1980-01. Steep-sloped roofs (pitch exceeding 2:12) must have a 3-year aged SRI of 29 or higher.

• Requires R-30 Insulation• Required unless determined to be not economical by life

cycle cost analysisThere is a new cool roof calculator developed by Oak Ridge

National Laboratory (ORNL) and Lawrence Berkeley National Laboratory with funding by the DOE and CEC that provides cool roof assessments and roof options through simulations. To see it in action, visit RoofCalc.com.

DOE is also studying the Urban Heat Island Effect and urban pollution abatement. ORNL is also researching for validation of global cooling models.

ORNL performed research on cool roofs in 2010 using reflective coatings with and without ceramic particles. According to sample data for a sunny April 2010 day, a coating with no ceramic beads has an initial solar reflectance of 0.88. The coating with ceramic beads has a solar reflectance of 0.80. Chicago’s 2009 Energy Code requires reflectivity of .72 new and .55 solar reflectance aged after 3 years.

Andre concluded, “Working in partnership with industry, DOE is undertaking both development and enabling research in the roofing market to make available to building owners more energy-efficient and affordable roofing system choices.”

DOE research combined with NRCA and CRCA resources provide the best of both worlds, scientific and practical. We are very thankful for DOE sharing Andre’s knowledge with CRCA’s Trade Show & Seminars attendees. Contact a CRCA Member to understand what is best for roofs in Chicagoland and beyond. n

Roofing work is difficult and requires a high degree of training and professionalism. The CRCA Member Contractors’ workforce job is to work with materials at one or 100 stories and return home each night safely.

At CRCA’s Trade Show & Seminars, contractor foremen and superintendents spent time learning about safe roofing practices from the best. CRCA’s Safety Committee including Safety Consultant Frank Marino and OSHA’s Jacob Scott together presented “Fall Restraint vs. Fall Arrest.”

CRCA Safety Consultant Frank Marino started, stating “According to the definition in the Federal OSHA standard, a personal fall arrest system means a system used to arrest an employee in a fall from a working level.”

Fall arrest consists of an anchor point, connectors, a body belt or body harness and may include a lanyard, deceleration device, lifeline, or suitable combinations of these.

The entire system must be capable of withstanding the tremendous impact forces involved in stopping or arresting the fall. The forces increase with the fall distance due to acceleration (a person without protection will free fall 4 ft in 1/2 second and 16 ft in 1 second!).

CRCA and Safety

A fall restraint system consists of the equipment used to keep an employee from reaching a fall point, such as the edge of a roof or the edge of an elevated working surface.

The most commonly utilized fall restraint system is a standard guardrail. A tie off system that “restrains” the employee from falling off an elevated working surface is another type of fall restraint

Jacob Scott’s presentation covered steep slope fall protection and compliance. Steep slope roofs have new rules that eliminate the use of “slide guards.” Want more info? Check out www.CRCA.org 2012 CRCA Trade Show & Seminars pages. n

Gary Auman, Esq., Dunlevey, Mahan and Furry has specialized in safety and law for decades. He’s been active in safety associations volunteering.

According to 1926.501(b)(10), conventional fall protection or a combination of: 1. Warning Line System & Guardrail System; 2. Warning Line System and Safety Net System; 3. Warning Line System and Personal Protective Equipment; 4. Warning Line System and Safety Monitor System.

“Nowhere in standard documents has it stated that a safety monitor is only needed when an employee is between the warning line and roof edge...But, OSHA has issued some interpretative letters which draw this requirement into question,” stated Auman.

For steep sloped roofing, OSHA issued the following rules: June 18, 1999 – STD 03-11-00 Interim Fall Protection

Guidelines for Residential ConstructionDec. 16, 2010 – Dr. Michaels announces rescission of STD

03-11-001June 16, 2011 – STD 03-11-002 – rescission documentSept. 15, 2011 – Rescission effective for enforcementWhy did OSHA rescind the “slide guard rule”? Mr. Auman

brought statistics that showed falls from roof accounted for almost 50% of total falls in 2009, up from about 25% in 2005. Secondly, he presented that the interim guideline in

Fall Protection for Steep Sloped and Low Sloped Roofs

1999 was not meant to be permanent. OSHA also received a recommendation from a trade group to rescind the directive.

The NRCA is appealing this through legislative means and conversations with OSHA directly in Washington.

For the immediate future, the alternative is for contractors to develop a written fall protection plan for each project showing that the conventional fall protection is infeasible or creates a greater hazard. “OSHA does not consider economic infeasibility a basis for providing conventional fall protection, as they presume it is feasible.”

At the seminar, Mr. Auman provided information about how contractors can comply with the new regulations. CRCA appreciated Mr. Auman’s program on safety. Regardless of what role a person plays in the construction process, safety is taken seriously by CRCA. n
