EFFECTS OF MULTIPARAMETER CHANGES ON ENERGY USE OF LARGE BUILDINGS

We describe the development of a methodology for predicting the effect s 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 b uilding was coded for energy performance simulation by the DOE-2 compu ter program. A database of simulation results was created from which t he coefficients of the Taylor series expansion were derived. Test resu lts using this energy predicting methodology provided reasonably accur ate estimates of the total and cooling energy of a generic building in Singapore.
