Development of a Simulation Toolkit for the Selection of High-Performance Systems for Office Buildings in Hot and Humid Climates (Phase I: Calibrated Simulation of the Case Study Building)

摘要

This paper reports on the development of an easy-to-usetool for the selection of high-performance systemsin office buildings in hot and humid climates. In thispaper, the preliminary results of a calibrated simulationof a typical large office building are presented for theJohn Connally building (124,000 sq-ft) in CollegeStation, TX. To calibrate the DOE-2 simulation model,measured data were retrieved from permanentlyinstalled data loggers in the building, which measuredwhole-building electricity use and sub-metered coolingelectricity use, lighting and miscellaneous equipmentuse, as well as thermal energy measurements forchilled water and hot water use. Also used in thecalibration process were portable data loggers forcomparing the performance of the building?s air-handlingunits with the simulated performance. For thecalibration of the DOE-2 model, several calibrationmethodologies were used, including manual & iterativecalibrations, graphical & statistical analysis, andsignature analysis. This calibrated simulation modelwill be used as a base-case model for the developmentof a easy-to-use simulation tool for the selection ofhigh-performance systems in office buildings in hotand humid climates. This paper presents the calibratedsimulation results of the office building and outlinesthe additional steps for the development of the high-performancesystems selection tool.
