GPG Outbrief webinars are presented by national laboratory researchers and include results from real-world evaluations, as well as feedback from facility managers at test-bed locations. Attendees are eligible to receive 1 continuing education credit from the American Institute of Architects for attending webinars.Recordings of past webinars and a schedule of upcoming webinars can be found here.
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 We have therefore withdrawn this report, findings and other summary material, pending revision.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.
