5. KPPC Kentucky’s Resource Center for Environmental Sustainability Knowing System’s 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)

6. 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

7. 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.

9. 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 9

10. KPPC Kentucky’s Resource Center for Environmental Sustainability KEEPS Thermostat Settings Tool: Instructions

11. KPPC Kentucky’s Resource Center for Environmental Sustainability 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. KEEPS Report Input 11

12. 12 KPPC Kentucky’s Resource Center for Environmental Sustainability 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
