Per the Building Technologies Office (BTO), US Dept of Energy: "...Successful implementation of high-performance control has been shown to reduce HVAC energy use in commercial buildings by 30%. Nationwide deployment would correspond to an absolute reduction of >3% of total U.S. energy consumption. That is roughly equivalent to the energy produced by all U.S. solar and hydro power combined in 2021".Â
