Energy Utilization Index Method for Predicting Building Energy Use. Volume I. Method Development.

摘要

This report describes development of the Energy Utilization Index (EUI) method for manually calculating monthly and annual energy consumption for buildings on military installations. The method uses basic building parameters such as U-factors, dimensions, occupancy, type of HVAC equipment, and average monthly weather conditions to arrive at a prediction for a building's monthly and annual energy use. Procedures for aggregating individual building consumption data into facility and installation consumption predictions are provided. The method for correcting the predictions to account for actual weather conditions is also described. Volume I describes the development of the EUI method, tells how the method is used, and compares predictions generated by the method with actual consumption data. A comparison of + or - 4 percent was shown for one building type.
