Abstract
A sensitivity analysis was carried out for 27 input parameters of a building energy performance simulation model. This research aims at providing useful design guidelines for architects to devote more attention to the design factors that have more influence in energy performance. The guidelines can be used in both energy-efficient designs for new buildings and effective energy retrofit for existing buildings. The simulation analysis was conducted for office buildings located in Seoul metropolitan area utilizing DOE-2.1D. The ranges of input values utilized in the analysis were set according to the practical information acquired from the survey research of existing buildings. Varying values for 27 input parameters, magnitude of affected output values was scrutinized and subsequent sensitivity coefficients were derived. Two types of input parameters, i.e., building design parameters and building operation parameters, were distinguished for heating and cooling loads.
