HVACR Technology Can Boost Supermarket Energy Efficiency

Over the last two decades, advances in HVACR technologies have produced significant improvements in energy efficiency. During that time, residential HVAC systems in the U.S. have gone from 10 SEER to 15 SEER, a 25 percent efficiency improvement. For commercial buildings, the source and site-energy-use efficiency improvements in ASHRAE 90.1 standards have increased more than 40 percent, with corresponding reductions in CO2 emissions.
