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.

Wireless Moisture Sensing Irrigation System > This technology measures the actual soil moisture directly at the plant root level in real time. Captured information is transmitted wirelessly and aggregated in the cloud. Based on algorithms, fault detection and business rules, irrigation is applied in the precise amounts needed, and leaks and broken sprinkler heads can be detected. Findings available in 2015.


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