End-Use Consumption by Principal Building Activity

Tables 2, 3a, and 3b show national-level end-use consumption for natural gas and electricity by principal building activity. For most building types, natural gas consumed for space heating greatly exceeded natural gas consumed for other end uses (Table 2). The two exceptions were food service buildings and lodging buildings. Natural gas consumed for water heating and cooking exceeded that for space heating in food service buildings; natural gas consumed for those two end uses plus “other” end uses nearly equaled space heating in lodging buildings.

Three building activities (food service, office, and warehouse) have notable departures in electricity end-use consumption compared with commercial buildings as a whole (Tables 3a and 3b). Electricity consumed for two end uses—refrigeration and cooking—exceeded half of total electricity consumed in food service buildings. Office equipment consumed about one quarter of electricity used in office buildings; and in warehouses, nearly 40 percent of electricity was consumed by lighting equipment.
