Lawrence Berkeley National Laboratory found 29% average perimeter HVAC savings compared to clear single-pane glass. Savings were found across climate zones.Learn More: Low-e Film >
GSA’s Proving Ground (GPG) program and DOE’s High Impact Technology Innovation Catalyst (HIT Catalyst) program have issued a joint request for information (RFI) calling for innovative pre- and early-commercial technologies in two categories: Behind-the-Meter Load Optimization and Improving Overall Building Operations and Maintenance. Technologies selected will receive third-party measurement and verification in tenant-occupied, operational buildings. Read more about this year's RFI.
GPG has recently completed assessments of the following technologies:
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 We have therefore withdrawn this report, findings and other summary material, pending revision.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. A final report will be released July 2017. Meanwhile, the overall recommendation from the M&V assessment remains unchanged. Both the variable-speed screw chiller and the magnetic bearing chiller should be considered for either new construction or end-of-life replacements. Both chillers performed effectively, offered similar integrated part load values (IPLV) and have rated energy consumption that is more than 35% better than FEMP standards for water-cooled chillers.
What Is GPG? The GPG program enables GSA to make sound investment decisions in next generation building technologies based on their real world performance.
