Advanced Rooftop HVAC Unit Controls Pilot

The Advanced Rooftop HVAC Unit Controls Pilot determined the expected energy savings and cost effectiveness of two market-ready advanced control strategies that were not previously implemented or evaluated on a large scale. CEE researchers field monitored 60 units on four Minnesota buildings to verify real building savings potential. They also assessed non-energy benefits including reliability, maintenance costs, and occupant comfort. In addition, the research team tested the optimization packages on rooftop units serving CEE’s main downtown office using wireless communication technology.


This project supported in part by a grant from the Minnesota Department of Commerce, Division of Energy Resources through the Conservation Applied Research and Development (CARD) program. And with co-funding by CEE in support of its nonprofit mission to advance research, knowledge dissemination, and program design in the field of energy efficiency.
