Summary Report of Building Energy Compilation and Analysis (BECA). Part V. Validation of Energy-Analysis Computer Programs.

摘要

BECA-V compiles and reviews comparisons of building energy-analysis techniques to measured building energy use. Preliminary results are summarized for the 12 studies reviewed to date. For commercial buildings, detailed computer programs were accurate to within about 10% when correct input data were available. For residential buildings, accuracy of building energy analysis programs was generally better than 1% when the buildings analyzed were intensively instrumented and monitored to eliminate errors in input. Two simplified programs suitable as building energy efficiency rating tools were, on average, accurate to within 15% for submetered and for less intensively monitored occupied houses.
