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

Nonchemical Water Treatment for Cooling Towers> This technology is designed to reduce wastewater associated with typical scale prevention equipment and to reduce operation and maintenance costs associated with scale prevention, especially where water is untreated or insufficiently treated. The process does not use chemicals, power, or additional water. Rocky Mountain Regional Project. Findings available in 2015.


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