With facilities totaling 1,000 buildings, achieving the University of California Davis’s goal of net-zero emissions by 2025 required ingenuity, innovation, and advanced data tools like the PI System™ and PI Vision™ from AVEVA. Three main sustainability initiatives—optimizing the chilled water system, improving HVAC scheduling, and switching from steam to low temperature hot water heating system—led to massive energy and monetary savings and ensured UC Davis is on track to meet its goal.
“We've achieved some of the more obvious efficiencies, but to reach our 2025 goal we need to go deeper. That increasingly requires things like user engagement, campus engagement, and optimization. In the last five years the use of real-time data and the PI System has become increasingly integral to our operations and our goals.”
David Trombly, Engineering Supervisor, UC Davis
