Stanford Medicine Children's Health cuts HVAC energy 30%
How a 521,000 sq. ft. hospital deployed occupancy-driven ventilation across 4 floors — with zero operational disruption.
Stanford's administrative wings sat empty every evening and weekend, but the HVAC kept running full blast. So their facilities team integrated R-Zero’s AI Energy Efficiency directly into their existing Alerton BMS – no rip-and-replace, no downtime, no disruptions. The result: one of the largest children's hospitals in the country is now saving energy in real time, with comfort scores untouched.
