Effects of Building Physics Form on Energy Consumption for Buildings

Abstract

The building sector plays an important role in urban energy conservation and CO2 emissions reduction. Therefore, it is necessary to fundamentally explore the influencing factors and mechanisms of building energy consumption. This study aims to explore the impact of building physical form on energy consumption for buildings. Firstly, this study uses different types of buildings as research objects. And method of combining EnergyPlus and GIS is used to calculate building energy consumption. Then adopting regression analysis to evaluate the impact of six building form indicators on building energy use. The results show that building coverage ratio (BCR) has a positive relationship with point-type building energy consumption. And among mix-type buildings, sky view factor (SVF) has a positive impact on energy consumption, and building coverage ratio (BCR) has a negative impact on it. As for slab-type buildings, total wall surface area (WSA) has a positive effect on energy consumption, and building floor (BF) has a negative effect on energy consumption. However, the indicators are not enough to explain the building energy consumption, and further exploration is needed.
