Estimates of energy consumption by building type and end use at US Army installations

This report discusses the application of the Lawrence Berkeley National Laboratory (LBNL) End-use Disaggregation Algorithm (EDA) to 12 U.S. Army installations nation-wide in order to obtain annual estimates of electricity use for all major building types and end uses. The building types include: barrack, dining hall, gymnasium, administration, vehicle maintenance, hospital, residential, warehouse, and miscellaneous. Up to 8 electric end uses for each building type were considered for EDA application. These electric end uses include space cooling, ventilation (air-handling units, fans, chilled and hot water pumps), cooking, miscellaneous/plugs, refrigeration, exterior and interior lighting and process loads. Through building simulations, we also obtained estimates of natural gas space heating energy use.

The average electricity use by end use for these 12 installations and For Hood are as follows. HVAC, miscellaneous, and indoor lighting end uses consumed the most electricity, with 28, 27, and 26% of the total use, and 3.8, 3.5, and 3.3 kWh/ft², respectively. Refrigeration, street lighting, exterior lighting, and cooking end uses consumed 7, 7, 3, and 2% of the total electricity use, and 0.9, 0.9, 0.4, and 0.3 kWh/ft², respectively.
