Advocacy

Glazing advocacy for the industry

Your industry advocate, NGA promotes and defends the use of glass in the built environment.

We are:

  • working with domestic and international standards and codes bodies

  • providing education on the benefits of glazing and glass building products

  • representing the glass industry’s best interests on key issues

NGA’s advocacy and technical initiatives respond to the relentless, ever-changing challenges to our industry. We thank our volunteer members, industry partners and expert consultants who work tirelessly to ensure glass and glazing is at the forefront of all discussions impacting building regulations and innovation in construction.

Review current activities

NGA is actively involved with standards and codes bodies including the International Codes Council, ASTM International and ASHRAE, among others, to promote and defend the use of glass in the built environment. Recent activities include:

ASHRAE 90.1-2019

For the last three years, the NGA advocacy team has worked with other industry associations and public officials to successfully work new performance requirements for windows, doors and skylights into the ASHRAE 90.1 energy standard for buildings, which were approved in Spring 2019. Read more.

ASHRAE 90.1-2019, published in October 2019, includes the following revisions: 

  • Updated commercial fenestration criteria  
  • No reduction in window area 
  • Increased daylighting controls  
  • Cleared barriers for use of VIG in walk-in coolers and freezers 
  • Commissioning requirements including more focus on air leakage  

UPDATE: ASHRAE 90.1 SSPC 90.1 Energy Standard for Buildings Except Low-Rise Residential Buildings held their Spring Interim meetings in April 2021, where the NGA Advocacy Technical team represented the glass and glazing industry.

ASTM

ASTM Committee E06 on Performance of Buildings and Committee F12 on Security Systems and Equipment work group topics include Design of Glass Railings, Guards and Balustrades, Sealed Insulated Glass, Security Glazing, Glass Floors & Stairs, and Impact Resistance. Several security standards and glass strength standards will be going out for ballot by summer 2021. 

CSA A460 Bird Friendly Building Design

NGA has submitted comments designed to promote and protect new and current glass technologies in Canada’s CSA A460 standard, which covers bird-friendly building design in both new construction and existing buildings. Learn more

DOE Building Energy Codes Program 

NGA’s Energy Code Consultant, Dr. Tom Culp, Birch Point Consulting, Co-Vice Chair ASHRAE Std. 90.1, presented at the virtual DOE Building Energy Codes Program in the panel discussion “Looking to the Future - What's in Store for ASHRAE Standard 90.1.” Tom’s presentation focused on the onsite renewable energy requirements in 2022 ASHRAE 90.1. Other topics covered in this session are thermal bridging, envelope back-stop and HVAC metrics. Watch a recording of the session. See the full program and download presentation slides at energycodes.gov.  

ICC Procedural Changes to the Code Development Process 

The International Code Council (ICC) is considering changes to the code development process based on issues presented to the Board Committee on the Long-Term Code Development Process (Blue Ribbon Committee). The board has approved two updates so far- cost impact and assembly consideration. Watch this page for further updates as they develop.   

International Standards Organization

ISO International Standards Organization Technical Committee 160: Glass in Buildings held a meeting of the Chairman Advisory Group (CAG) on April 12. The CAG discussed updates to ISO TC 160 standards for Glass in Buildings including BIPV, dynamic glazing and glass strength.

School Security

While current building codes do not require security glazing in schools, a growing number of school districts nationwide are looking to meet voluntary security glazing standards to provide additional protection for their buildings. NGA is participating in a multi-industry effort with the National Fire Protection Association, ASTM International and ICC to provide guidance in this effort. In addition, NGA presented this topic as part of its Thirsty Thursday webinar series and published a glass technical paper on school security in February 2021.

California AB262

NGA’s Forming Committee issued public comments on California AB262, voicing concerns about the bill’s technical flaws which will affect the flat glass manufacturers and the industry. NGA also responded regarding facility specific data for the implementation of CA AB262.

On January 1, 2021 the California Department of General Services (DGS) established maximum acceptable Global Warming Potential (GWP) limits for flat glass and other materials covered under CA AB262.

  • The CA DGS GWP limit for flat glass is 1.72E+03 kg CO2-eq.
  • This limit matches the request made by NGA’s Advocacy and Forming Committees for 20% above the industry wide flat glass GWP.
  • The established limit ensures that all North American flat glass manufacturers have the opportunity to supply glass products to government works projects in California.

See our GWP one-pager on this topic.

Known as the Buy Clean California Act, AB262 asks bidders on public works projects in California to submit an EPD, or Environmental Product Declaration, for specified flat glass products. NGA continues to work with supporters of the bill to clarify the language, ensure they understand the effects, and educate them about the glass and glazing industry.

To learn more about EPDs and their potential impact on your glass company, watch “The Why, How and Business Value of LCA and EPDs.”

NYC’s “Green Deal”

In April 2019, the glass industry witnessed this jarring headline coming out of New York City: "NYC’s ‘Green New Deal’ to Ban Glass, Steel Skyscrapers." And while research revealed the mayor was not actually announcing a ban on glass and steel buildings in New York City, his anti-glass statements and over-simplistic labeling of glass as a poor energy performer were harmful to the glass industry. Since then, the NGA, relying on voices from the code, architect, and glazing contractor communities, has addressed how initiatives like the Green New Deal can hurt the glass industry, and educated the industry on what glass companies can do to comply with this requirement. Read, “What You Need to Know about the Green New Deal.”

NGA provides advocacy one-pagers to format advocacy requests related to glass industry issues into a quick-reference format to help stakeholders and legislators easily understand issues at hand. Download NGA's advocacy one-pagers below.

GICC works directly with NGA’s code consultants to build greater knowledge and acceptance of architectural glass, glazing materials, and glazing systems as safe, efficient, effective, and economical construction products. GICC seeks to educate model code, standard-setting, and building code organizations and officials, as well as the general public.

The GICC met virtually on November 5, 2020 to discuss updates to the ICC Building Code and the Canadian Model National Building Codes. GICC welcomed new leadership to the Executive Committee:

  • GICC Chair - Devin Bowman of Technical Glass Products replaces Greg McKenna of Kawneer Company
  • GICC Vice Chair - Steve Thomas of Guardian Glass replaces Darrell Smith of IWFA
  • GICC Secretary/Treasurer - Ron Hull of Kuraray continues his service in this role

Thanks again to our GICC leadership for their time and dedication to serving the glass and glazing industry interests in the building codes.
