| Abstract |
Building energy performance evaluation is required in the design stage to ensure a target energy consumption for a proposed design. However, in an early design stage, a building performance evaluation is very limited due to insufficient building data for systems and constructions. The aim of this study is to develop an energy performance evaluation method for a building with twisted shape in early design stage. This study utilizes parametric modeling and BIM based interoperability between an architectural model and a building energy analysis model. This study develops a geometry simplification method for a building with a twisted shape based on parameters in early design stage. The simplified geometry information is transferred to an analysis model through interoperability protocol, e.g., gbXML. Iterative simulations are conducted based on specified design parameter with a range. This study established a building energy performance evaluation process in early design stage and could derive the best building shape for energy performance. |
