An exhaustive parametric study on major passive design strategies of a typical high-rise residential building in Hong Kong

Abstract

This paper presents a comprehensive sensitivity analysis (SA) of the typical High-rise residential building in Hong Kong. A generic building model is constructed with proposed natural ventilation strategies subject to the examination of thermal comfort criteria. The numerical modelling exhaustively investigate the thermal and energy responses based on the variation of different passive design parameters. The parametric studies with respect to multiple output indices are able to prove that the window solar heat gain coefficient is the most influential architectural design factor. Different thermal comfort models including the Adaptive Comfort Standard (ACS) and Predicted Mean Vote (PMV) are compared in estimating the indoor environmental quality (IEQ) for the generic building. It is believed that sensitivity analysis benefit the identification of important inputs to facilitate further optimization of the building performance in initial plan stages.
