Savings potential of dual fuel heat pump rooftop units and energy recovery ventilators in Minnesota

This report provides an analysis of energy and bill savings achievable through the use of dual fuel heat pump RTUs and energy recovery ventilators (ERVs) in Minnesota’s commercial buildings. The primary goal is to quantify the potential savings across eight common commercial building types, which represent 72% of the commercial buildings in the state. By focusing on Minnesota’s cold climate and building stock, the study evaluates the performance of these technologies both individually and as a combined system.

The model developed by CEE examines how dual fuel heat pump RTUs and ERVs can reduce energy consumption and utility bills. It assumes RTUs have a switchover temperature of 30ºF as recommended by manufacturers.

Minnesota's Efficient Technology Accelerator is funded by investor-owned utilities and administered by the Minnesota Department of Commerce, Division of Energy Resources.
