Proceedings. Calibration methodology for retrofit projects using short-term monitoring and disaggregated energy use data. Symposium on Improving Building Systems in Hot and Humid climates [10, 13-14 may 1996, Texas].



This paper present an improved methodologic to calibrate energy simulation models to better represent the actual energy use breakdowns in existing buildings. The goal of this methodologic is to help architects and enginners accurately determine the current energy used and identify any energy-related problemsin the building before proposing the retrofit desing solutions, without conducting long-term monitoring. The methodologic includes procedures to conduct sistematic data collection, on-off test to determine the power densities of the electrical loads, up to four weeks of building energy monitoring to derive the energy use profiles temperature settings, and disaggregation of the measured energy use data. The procedures also utilize the monthly utility billing records and site weather data. The calibration tothe measured data is done on both houly and mounthly basis. the procedures are built into a computer program and integrated with previously developed simulation software. The user interface of the program includes guidelines to help the user decide wich simulation input variables has to be altered in orderto match the measured data. It also produces graphical outputs to help in visualizing the results, and several guidelines to help study different retrofit strategies after the model has been calibrated..
