Study refines air conditioning saturation in U.S. homes
Saying there are 100 million housing units in the United States hasn’t helped researchers distinguish between the hvac systems in a 3,000-sq-ft colonial house and those in a 750-sq-ft apartment.
Now, however, the study by Lawrence Berkeley National Laboratory divides the country’s housing sector broadly between 67 million single-family detached homes (including manufactured housing) and 33 million housing units in multifamily buildings.
