ComStock Measure Scenario Documentation: Reduced Thermostat Setbacks for Heat Pumps

Summary

Commercial buildings frequently use significant thermostat setbacks during unoccupied hours, which can hinder the efficiency of heat pumps, leading to reliance on supplemental heating and increased demand. This report from the National Renewable Energy Laboratory (NREL) documents a ComStock model scenario that explores the effects of implementing a milder 2°F unoccupied thermostat setback for heat pump rooftop units. The analysis projects substantial national annual savings in natural gas, utility costs, and carbon emissions from this approach.
