Comparison of empirically measured end-use metered data with DOE 2. 1 simulation

This paper examines how well a DOE 2.1B simulation which has been calibrated for a 20,000 square foot building reflects actual end-use energy consumption. Empirically measured data are compared with simulation results for end-use energy consumption, heating and cooling loads by thermal zone and month, monthly energy use, and monthly peak demand. The limitations of the DOE 2.1 code with respect to modeling the heat pump system are discussed and implications analyzed. An examination of schedules used to model the building highlights the importance of accurate information about building operation and its impacts on the simulation results.
