Occupancy-Responsive Adaptive Thermostats for University Residence
Halls• Improved control and facilities managemento Excellent on-board algorithms
• Can achieve substantial savings (20% or more, but not always)o Savings is sensitive to application, climate, occupancy
patternso Thermostat needs to have full control over space to achieve
savingso Interactive effects between rooms diminish savingso HVAC sequence of operations can essentially void control
• Recommended simple tests to determine if a building will achieve savings
• Simple models tend to over-predict savings
