Energy Use by Building Type


Total Major Fuel Consumption by Building Type

  • Commercial buildings in the U.S. used a total of approximately 5.7 quadrillion Btu of all major fuels (electricity, natural gas, fuel oil, and district steam or hot water) in 1999.
  • Office buildings used the most total energy of all the building types, which was not a surprise since they were the most common commercial building type and had an above average energy intensity.

Major Fuel Consumption per Building by Building Type

  • Because there were relatively few inpatient health care buildings and they tend to be large, energy intensive buildings, their energy consumption per building was far above that of any other building type.

Major Fuel Consumption per Square Foot by Building Type

  • Buildings types that are more likely to contain specialized, high energy-consuming equipment—food service (cooking and ventilation equipment), inpatient health care (medical equipment), and food sales (refrigeration)—were the most energy-intensive types, all using at least twice as much energy per square foot as the average commercial building.

Major Fuel Consumption per Square Foot per Hour by Building Type

  • When the hours of building operation were taken into account, building types that are characterized by long working hours had a lower energy intensity than those that are normally used for shorter periods of time.
  • Inpatient health, which used the most energy per square foot, became relatively less intensive when operating hours were taken into account, since hospitals are typically open around the clock.
  • Education buildings, on the other hand, which are in use for shorter periods of time, become relatively more intensive than when looking just at energy use per square foot.
