Despite the increasing interest in BIM and energy saving, research on developing BIM-based design techniques for analysing the energy performance has a long way to go. Therefore, difficulties in the analysis of energy performance relative to the size, geometry and other aspects of buildings hinder an objective assessment of design. Also, the analysis of energy performance has been separated from the environment-friendly design techniques, and thus the development of low-carbon design techniques relying on insulation and HVAC system is considered to override the genuine design technique per se. To address the challenge, the present paper sets up the goal to develop a design technique based on energy performance for supporting the Green BIM design in the initial design phase. For designers to intuitively understand the results of energy performance analysis using a BIM tool in the earliest design phase and reflect them in design, only the basic building design components of mass-shaped buildings are used to analyze their correlations with energy performance. The proposed method allows the mass design to be freely implemented considering the energy performance even when the design and primary structures are not determined, and subdivides the phase into the energy performance analysis for design and that for details and HVAC system. The clarification of the purposes of energy performance analysis is deemed to maximize the energy performance and efficiency in comparison to invested time and resources.
