Optimal Design of Zero Energy Buildings Considering Weather Uncertainty in Subtropical Regions

Hangxin Li, Shengwei Wang, Howard Cheung

Abstract: The actual performance of buildings in operation can differ significantly from their design performance because of various uncertainties throughout their life-cycle. However, current design practice seldom considers uncertainties. In this paper, a holistic method integrating sensitivity analysis and probabilistic optimal design is proposed for zero/low energy buildings. A comprehensive objective, integrating energy consumption and winter discomfort degree, is defined for design optimization in subtropical regions. A case study is performed using Hong Kong Zero Carbon Building as the reference building. Results show the key envelope design parameters in subtropical regions as well as their probabilistic optimal design.
