Thermostat Setting Recommendations

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)

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

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.

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

KEEPS Thermostat Settings Tool: Instructions

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.

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
