Abstract: This paper reports on the development of an easy-touse tool for the selection of high-performance systems in office buildings in hot and humid climates. In this paper, the preliminary results of a calibrated simulation of a typical large office building are presented for the John Connally building (124,000 sq-ft) in College Station, TX. To calibrate the DOE-2 simulation model, measured data were retrieved from permanently installed data loggers in the building, which measured whole-building electricity use and sub-metered cooling electricity use, lighting and miscellaneous equipment use, as well as thermal energy measurements for chilled water and hot water use. Also used in the calibration process were portable data loggers for comparing the performance of the building's air-handling units with the simulated performance. For the calibration of the DOE-2 model, several calibration methodologies were used, including manual & iterative calibrations, graphical & statistical analysis, and signature analysis. This calibrated simulation model will be used as a base-case model for the development of a easy-to-use simulation tool for the selection of high-performance systems in office buildings in hot and humid climates. This paper presents the calibrated simulation results of the office building and outlines the additional steps for the development of the high-performance systems selection tool.
