Abstract
A computer simulation tool, named "CHAMPS-Multizone" is introduced in this paper for analyzing both energy and IAQ performance of buildings. The simulation model accounts for the dynamic effects of outdoor climates (solar radiation, wind speed and direction, and contaminant concentrations), building materials and envelope system design, multizone air and contaminant flows in buildings, internal heat and pollutant sources, and operation of the building HVAC systems on the building performance. It enables combined analysis of building energy efficiency and indoor air quality. The model also has the ability to input building geometry data and HVAC system operation related information from softwares such as SketchUp and DesignBuilder via IDF file format. A "bridge" to access static and dynamic building data stored in a "virtual building" database is also developed, allowing convenient input of initial and boundary conditions for the simulation, and for comparisons between the predicted and measured results. This feature will also potentially enable on-line calibration of the simulation model parameters, and improve the prediction accuracy for intelligent control of building energy and environmental systems. This paper briefly summarize the developmental history of the program, the mathematical models used, assumptions adopted, method of implementation, and preliminary verification and validation results. The needs and challenges for further development are also discussed.
