GSA Low-Embodied Carbon Standard

The United States General Services Administration announced that Vitro Architectural Glass, an NGA member company, was awarded a project for American-made sustainable glass for the Virginia courthouse.This project is part of GSA’s six-month pilot program applying interim Inflation Reduction Act Low Embodied Carbon Material Requirements for 11 GSA construction projects, three including glass.

Legislative advocacy

NGA provided input and responded to requests for information on several legislative proposals at the federal and state levels.

Glass & Glazing Advocacy Days

NGA hosted the second annual Glass & Glazing Advocacy Days March 27-28 in Washington, D.C., to advocate and educate about glass in the built environment. NGA staff and members met with legislative representation from several states, and with representatives from the U.S. Environmental Protection Agency and U.S. Department of Energy to discuss five policy priorities and the vital role glass plays in the built environment.


Introducing NGA’s newest goal: To advance the industry as a viable, thriving and exciting career path. Labor—specifically a lack of skilled labor—continues to challenge installing companies and glass fabricators, with both Top Glaziers and Top Fabricators citing it as their biggest obstacle in 2023, following inflation and the economic slowdown. NGA’s workforce development efforts fall into three areas: raising awareness, recruitment, and training and apprenticeship.


Once aware of the trade, the goal is to convert interested people into employees, and NGA is exploring ways to help connect potential employees with industry companies. In 2023, NGA participated alongside member companies at the Associated Builders and Contractors Inland Pacific Chapter Construction Trades Night and Technical Glass Products’ (TGP) Manufacturing Day events to help recruit high school students interested in a career in glazing or glass fabrication.

Raising Awareness

While the glass industry is not alone in the labor shortage—the construction workforce shortage tops half a million in 2023—it does face the additional challenge of educating the public about the glass and glazing trade. Raising awareness of the glass and glazing industry, particularly among high school students and second-chance career candidates, remains key to eventually easing the labor shortage. This year, NGA launched the “Become a Glazier” webpage to educate the public about the glazing trade and the opportunities it offers.

The NGA Foundation

This year, FHC | Frameless Hardware Company committed to continue and increase its generous support of NGA’s workforce development efforts. FHC remains the largest contributor to the NGA Foundation and has covered the curriculum costs for more than 273 glazier apprentices throughout the country, in addition to funding the development of new training and recruitment initiatives. “Our business and this industry only work if we have glaziers in the game to keep glass in buildings,” says Chris Hanstad, president, FHC. “They are our livelihood and we’ll spare no efforts in equipping them to grow. We grow when they grow, and NGA’s education platform is the most impactful solution for us to get behind, support and realize that goal.”

Training + Apprenticeship

Ensuring member companies and the industry have access to training resources remains a top priority for NGA, and it continues to invest in the and MyGlassFAB platforms. The association also offers the NGA Glazier Apprentice Curriculum for organizations and companies that want to establish a glazier apprenticeship program approved by the U.S. Department of Labor. Students who complete the NGA Glazier Apprentice Curriculum will earn a jointly endorsed NGA/NCCER credential indicating a journeyman-level minimum competency reached through knowledge and performance.
