Green Proving Ground



Request for Information

GPG and DOE’s High Impact Technology (HIT) Catalyst have issued a joint RFI calling for innovative emerging building technologies that can cost-effectively transform the operational efficiency of federal and commercial buildings. The RFI is now closed.

Published Findings

GPG has recently completed assessments of the following technologies:

Low-e Window Film

Linear LED Retrofits

Smart Ceiling Fans White Paper

Control Optimization System for Chiller Plants

Honeycomb Solar Thermal Collector

LED Downlight Lamps for CFL Fixtures



NOTE: GSA has found substantive issues with our test-bed evaluation of Variable-Speed Direct-Drive Screw Chiller technology, Report # GPG-031. Our paramount concern is to ensure that GPG test-bed evaluation outcomes are accurate, objective and credible. We have therefore withdrawn this report, findings and other summary material, pending revision. We apologize for any inconvenience caused.
