Overview
The facility management team at California State University Dominguez Hills (CSUDH) is driven by a core commitment to continually reduce campus energy usage through modern technology. To this end, they have partnered with facil.ai to improve their chiller performance.
Before facil.ai’s involvement, the three chillers operating in the CSUDH central plant were achieving roughly 0.7 kW/ton energy efficiency. After a two-week ramp-up period for facil.ai, CSUDH started consistently seeing chiller energy efficiency of approximately 0.3 kW/ton, while improving zone temperature comfort in the spaces and equipment served by the chillers.
Nine months later, the chillers are performing better than imagined at record lows of 0.19 kW/ton (almost 20 Coefficient of performance). These results happened while Kenny Seeton, the Director of Central Plant Operations at CSUDH was on vacation, because facil.ai runs quietly in the background with little to no facility intervention required.
For reference, ASHRAE 90.1 standards define “best performance” at 0.45 kW/ton — beyond that
was previously unheard of.
