On-site Power and Renewables

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

Honeycomb Solar Thermal Collector > A solar thermal collector generates hot water, which can be used for service water heating (SWH), space heating, or process heat. This product employs a ‘honeycomb’ design that promises greater heat gain on the energy-collecting surface and thus higher efficiencies than traditional flat-plate or evacuated tube collectors. Findings available in 2016.


The Green Proving Ground program leverages GSA’s real estate portfolio to evaluate innovative sustainable building technologies.
