Water usage in commercial buildings accounts for nearly 10 percent of all water used in the United States, according to the U.S. Department of Energy. Buildings that use cooling towers for evaporative cooling can reduce water usage by employing more efficient water treatment technology.
The GPG program, working with federal laboratories, has tested the following building envelope technologies in GSA buildings.
Advanced Oxidation Process for Cooling Towers, January 2019*
Catalyst-Based Scale Prevention for Domestic Hot Water Systems, February 2015*
Monitoring & Partial Softening for Cooling Towers, October 2020*
Salt-Based & Chemical Inhibition for Cooling Towers, February 2019*
Wireless Soil-Moisture Sensors for Irrigation Control, April 2015
*M&V results demonstrate broad deployment potential.
