With the increase in the interest in low-carbon design technique development, there are active studies on development of energy performance-based design techniques using BIM. However, there is yet an inadequacy of clear standard for design quality evaluation to perform energy performance analysis using BIM at each stage of design. For this reason, development of low-carbon design techniques, which rely on insulation performance and HVAC system, is dominant rather than energy performance evaluation that is based on design including the size and shape of building. This result comes from a shortage of linkage between expression of cooling and heating load-oriented energy performance analysis result per unit area and design techniques. In particular, quantitative development was dominant due to rapid industrial development and urbanization in the 1970s to 80s and performance evaluation per unit area was commonly used due to legal and institutional problems. Besides, there was a lack of awareness of energy performance evaluation for design quality evaluation, in addition to simple design forms. But in the 2000s, construction design qualitatively developed and there was a rapid rise in the interest in performance-based atypical and eco-friendly design. In this situation, performance analysis per unit area and facility performance quality evaluation have limits in expressing or solving this. On the other hand, energy performance analysis was part of construction facility for HVAC system installation in the past. But currently, it is an important area of construction and environmental engineering and a core technology to consider maintenance of building at the initial stage of design. Nevertheless, it is hard for architects to simulate and understand analysis results, since energy engineering, mechanical engineering and electrical engineering-based analysis methods are applied and in energy performance-based design, they still should put emphasis on plans that depend on facility performance, not design. Therefore, this study aims to develop a visualization technique for energy performance-based design quality evaluation, which is easy for designers to understand, by applying various design elements and design techniques. It is anticipated that breaking from insulation performance and HVAC system-dependant energy performance-based design techniques, this methodology for performance-based design would make a contribution to development of BIM-based low-carbon design techniques.
