An Analysis of Electrical Consumption at Representative Army Installations.

This report describes analysis of monthly and daily electrical energy consumption data collected over 2 years from 8 electrical feeders at Fort Carson CO, and 20 different Army buildings at Fort Carson and at Fort Belvoir, VA. The work was conducted to determine why electrical energy consumption has been increasing at Army installations, and to provide a basis for determining methods to reduce consumption. It was determined that many Army buildings have a high minimum electrical usage (minimum demand) that amounts to up to 75 percent of total annual consumption. Tables and graphs are provided which amplify the significance of this minimum demand. It was concluded that a shift from emphasizing a reduction in occupant usage of electrical energy to a concentrated effort to minimize the continuous electrical usage caused by building operation and heating, ventilating, and air-conditioning (HVAC) systems should reduce electrical consumption at Army installations.
