Building Envelope

The Green Proving Ground program has commissioned Department of Energy National Laboratories to perform real-world measurement and verification of the following technologies in pilot installations in federally-owned buildings. Preliminary technology assessments are available below as PDFs.

Preliminary Technology Assessments

Dual Zone Indoor Shades [PDF - 246 KB] Dual zone indoor shades integrate two separate daylight control strategies into a single unit—an upper louvered blind that maximizes daylight harvesting and a lower roller shade that controls glare and reduces window heat gains and losses. Findings available in 2018.

Phase Change Materials [PDF - 215 KB] Phase change materials can be integrated into wall, roof, ceiling, attic and floor assemblies to improve the thermal performance of the building envelope and reduce air conditioning load. GPG Regional Project. Findings available in 2018.

The GPG program enables GSA to make sound investment decisions in next generation building technologies based on their real world performance.
