This study provides guidance for energy usage by primary cooling and heating equipment in commercial building and an overview of the factors contributing to energy use.

This study analyzes the national energy use in generating heating and cooling for commercial buildings to better understand where efficiencies can be improved and where research should be directed. The data is segmented by region of the country, type of building usage, type of equipment, and amount of floor space.

About half of the cooling energy used in the US is associated with Packaged AC (mostly Rooftop units), which also consumes approximately 25% of all heating energy. The Packaged AC contributes to much of the national HVAC energy use primarily because it is used in a majority of the buildings. However, the efficiency of the Packaged AC is lower on average than those of other equipment types such as water-cooled chiller systems. Other cooling equipments representing high energy use are centrifugal and reciprocating chillers.

The major user of energy-using category is Office, Mercantile and Service, and Public Buildings due to the large floorspace of the commercial sector. Of the other categories, education has a large floorspace but relatively modest HVAC use, while food services and health care categories are critical categories with high energy use. As far regions of the country, the South region represents the largest geographical energy use, in part because of large floorspace but also because of high energy use for cooling.
