Knowing Systems Capabilities Every building is unique, and some thermostat setbacks/setups may not be applicable. Work with facility manager, and make adjustments accordingly. Setbacks/setups depend on: Building usage Equipment s recovery capability Avoidance of building damage (pipe freeze/mold) KPPC Kentucky s Resource Center for Environmental Sustainability
Establishing Setbacks/Setups Schools can be setback/setup for up to 2/3 of the year Condition the building during greatest occupancy Consider initiating system setback/setup 1-2 hours before the majority of occupants exit KPPC Kentucky s Resource Center for Environmental Sustainability
Establishing Setbacks/Setups (cont.) What setpoints should building be set at when occupied by only a few people? Not recommended to set thermostats below 55 F to prevent pipe freeze or above 83 F to prevent excessive humidity. KPPC Kentucky s Resource Center for Environmental Sustainability
Thermostat Settings Data Collection KPPC Kentucky s Resource Center for Environmental Sustainability
KEEPS Thermostat Settings Tool Helps determine proper thermostat setpoints for school buildings/facilities Based on varying building usage patterns Calculations based on 1% heating and cooling savings per degree, per 8-hour setback See U.S. DOE s Energy Savers website KPPC Kentucky s Resource Center for Environmental Sustainability 9
KEEPS Thermostat Settings Tool: Instructions KPPC Kentucky s Resource Center for Environmental Sustainability
KEEPS Report Input Locate HVAC & Controls in the KEEPS Assessment Report and modify respective figures and other necessary words/sentences for your specific school. Modify the inset box with the results calculated from the KEEPS Thermostat Settings Tool. KPPC Kentucky s Resource Center for Environmental Sustainability 11
Managing Thermostat Settings Building Automation System (BAS) Gives control to only energy manager, facility manager, superintendent Programmable thermostats Gives occupants control and responsibility Limited-adjustment thermostats Gives occupants limited control within 1 3 degrees Dummy thermostats Gives occupants no real control, only psychological feel of control Lockout covers Gives occupants no control 12 KPPC Kentucky s Resource Center for Environmental Sustainability
