ANALYTICS FOR PEAK EFFICIENCY

Green Proving Ground (GPG) leverages GSA’s real estate portfolio to evaluate innovative sustainable building technologies and provide recommendations on their deployment.

GPG SUPPORTS DEVELOPMENT OF INNOVATIVE TECHNOLOGIES

GPG assumes first-use risk and accelerates market acceptance by objectively assessing innovative sustainable building technologies in real-world environments.

HOW DOES GPG WORK?

Identify promising technologies at the edge of commercialization

Pilot technology installations within GSA’s real estate portfolio

Partner with Department of Energy national laboratories to objectively evaluate real-world performance

Recommend technologies with broad deployment potential

GREEN PROVING GROUND, 2011-2015

Received 450 technology applications

Selected 48 technologies for M&V

Published 24 DOE laboratory assessments

Identified 14 broad deployment potential

Deployed 5 technologies with broad deployment potential
