Lightweight Secondary Windows Simplify Installation
A cost-effective and efficient way to improve thermal performance and occupant comfort of older windows
Lightweight Quad-Pane Windows Contribute to Net-Zero Goals
Same thickness as double-pane but with 24% more energy savings
Low-Cost Submetering for Tenant Billing
Accurately tracks energy consumption, <2% measurement error.
Monitoring and Partial Softening Saves Cooling Tower Water
The supplemental system reduced blowdown by 52% and overall cooling tower water use by 15%.
AWT has Potential for Deployment Throughout GSA
Alternative water treatment systems were shown to maintain water quality, save water, and reduce cooling tower cleaning, with payback under three years.
The Center for Emerging Building Technologies' two programs — Green Proving Ground (GPG) and Pilot to Portfolio (P2P) — enable GSA to invest wisely in next-generation building technologies.
Green Proving Ground (GPG)
Test-bed measurement and verification (M&V) — published reports, infographics and summary documents in the following categories:
All Technology M&V InfographicsPilot to Portfolio (P2P)
Deployment support — resources for GPG-proven technologies:
- Overview of P2P
- GPG-Validated Technologies for GSA
- On-Demand Webinars
