Weather Station for Irrigation Control

Weather-based irrigation controls use local weather data to measure and respond to irrigation water needs in real time. 

GSA embarked on a pioneering effort to tie this irrigation control system to the building automation system at the Hart-Dole-Inouye Federal Center in Battle Creek, MI. 

GPG and researchers from the Pacific Northwest National Laboratory (PNNL) found potential water savings of up to 66%.
