Suggestions on the definition of building shape in national standards–simulation of typical building models with EnergyPlus

Abstract: Building shape coefficient is defined as the ratio of building superficial area which contacts the outdoor air and the building volume. Smaller building shape coefficient helps save energy. High-rise buildings are very easy to meet the national standard limits for the shape coefficient of 0.4 or 0.3. The purpose of the thesis is to explore the impact of high-rise public buildings shape coefficient of energy consumption and put forward some suggestions to refine the request in national standards about the shape coefficient. Energyplus is used to simulate the energy consumption of high apartment and high office building in China's typical climate areas and to study the impact of building shape on building energy consumption. It is found that the present definition of building shape coefficient can not reflect building energy consumption correctly. Then this paper analyses how building energy consumption varies with shape coefficient. Finally, this paper puts forward some different difinitions of building shape coefficient and compare with the original to find the most reasonable one.
