Heating & Cooling
HVAC—heating, cooling, and ventilation—is responsible for more than a third of energy use in commercial buildings in the U.S. Smart designs can easily save upwards of 40% of that energy, often with strategies that offer instant or short payback. And good design that focuses on thermal comfort supports healthier, more productive occupants.
