Determination of building envelope is imperative in assessing the energy performance of the buildings. However, determining building envelope has been manually conducted, which contains the possibility of misjudgment that lead to low reliability and which deteriorates productivity. This research proposes an algorithm based on BIM to determine the envelope of buildings automatically when conducting assessment of buildings’ energy performance. To accomplish the objective, first, this study sorted out cases of parts of buildings that can be determined as building envelope. After sorting out, this study analyzed on each case. Second, this study established criteria for selecting parts in need of insulation to determine their possibility as building envelope and criteria for deciding whether the parts are exposed to the open air directly or indirectly. Finally, this study proposed a BIM-based algorithm for wall, roof, slab, window and door respectively to determine each’s possibility as building envelope. Applying the result of this research when determining building envelope can enhance the productivity as the manual analysis is replaced by automated calculation. Free from being biased, it will also improve the reliability.
