Effects of multi-parameter changes on energy use of large buildings

Abstract

We describe the development of a methodology for predicting the effects of multi-parameter changes on the energy use of large buildings. The methodology is based on the third-order Taylor series expansion whose coefficients are evaluated for several key building parameters. The building was coded for energy performance simulation by the DOE-2 computer program. A database of simulation results was created from which the coefficients of the Taylor series expansion were derived. Test results using this energy predicting methodology provided reasonably accurate estimates of the total and cooling energy of a generic building in Singapore.
