GSA Shares More "Green Proving Ground" Experience

With lessons learned from its own buildings, GSA reports conditions under which high-performance window panels, mag-lev compressors, and onsite PV are viable.

The U.S. General Services Administration (GSA) has shared results on three more technologies as part of its Green Proving Ground program. High-performance window panels and variable-speed chillers produced substantial efficiency gains in two of the latest case studies, and a comprehensive survey revealed some best practices for getting the most from solar photovoltaic (PV) installations.

These studies join six other published GSA evaluations of sustainable technology (see “Two Technologies Proven Effective in GSA Test Beds”), with 22 more selected to study next.
