GSA announced that it will test and evaluate 16 emerging sustainable building technologies and practices in select federal facilities under its Green Proving Ground program. Testing will determine the most effective technologies that may then be replicated on a wider-scale basis throughout the GSA inventory, with the goal of transforming markets for these technologies.

"GSA is leading the way in sustainable design and construction operations," GSA Administrator Martha N. Johnson said. "By using our real estate portfolio as a test bed for new technologies, we can then provide further innovation in energy efficiency standards and implement best practices that will lead the market."

The technologies selected were from a pool of approximately 140 projects across GSA's national portfolio that are currently implementing innovative or underutilized sustainable building technologies. The 16 technologies and practices were selected for evaluation because they have the greatest potential to meet GSA's sustainability goals. Examples of the technologies chosen include wireless temperature sensors, electrochromic windows, high R-value windows, integrated lighting systems, thin-film photovoltaic panels, solar water heating with integrated photovoltaic panels, chilled beams, and non-chemical water treatment systems.

With support from the Department of Energy's National Laboratories, the Green Proving Ground program will perform enhanced testing, monitoring and evaluation on these selected technologies. Notable findings from all of the projects will be used to support the development of performance specifications for GSA's real estate portfolio and other federal agencies. Additionally, testing these technologies will assist industry in deploying the technology and practices studied.
