The Department of Athletics, Physical Education, and Recreation (DAPER) operates 69 buildings on the Stanford campus, totaling almost 800,000 square feet. In 2015, DAPER completed energy efficiency projects in six of the buildings consuming the most energy. In total, the projects are estimated to save DAPER over 800,000 kilowatt-hours, 5 million kBtu of hot water, and 180,000 ton-hours of chilled water, or over $400,000, per year. They will receive over $1 million in Energy Retrofit Program rebates. The projects were as follows:

  • Arrillaga Family Sports Center: Installed new variable air volume units along with a state-of-the-art direct digital controls system that will allow better scheduling and other efficiency strategies
  • Stadium: Added a new split system control to maintain the critical loads in data rooms while the air-handling unit maintains an occupancy-based schedule; exhaust fans are programmed to run only during occupied hours
  • Avery Aquatic Center: Installed chemical controllers to modulate pool chemical and temperature levels as well as schedule the variable frequency drive; installed controls equipment to schedule the locker room heating loops based on occupancy
  • Maples Pavilion: Upgraded controls system in 16 existing air handlers, installed demand-controlled ventilation, and reduced simultaneous heating and cooling
  • Ford Center: Optimized economizer operation on the four air handlers and scheduled selected heating, ventilation, and air conditioning (HVAC) equipment to run only during occupied hours
  • Arrillaga Center for Sports and Recreation: Increased ventilation and installed demand-controlled ventilation in the fencing and weight rooms; programmed certain HVAC equipment to run only during occupied hours; installed lighting occupancy sensors in the fencing room
