Since in the 1990s, architects have begun to apply sustainability to building design and to minimize the effect of buildings on the environment. despite these efforts, in actual application on design, the solution to reduce building energy consumption was only limited in mechanical equipment system or insulation performance of building envelope, but it forced up the cost of design definitely. The sustainable architecture couldn't widen its territory. Furthermore, it was limited on large public projects. Green BIM is the other way to achieve the sustainable architecture. BIM-based energy simulation tool in the Green BIM is a method to measure the energy consumption which influenced by a architectural elements : envelope, form and plan of building fixed in the early design stage. In the early design stage, by achieving the more efficient counterplan through BIM-based energy performance analysis, it will be able to realize the effective low-energy building design. This study aims to develop application method of BIM-based energy performance analysis tools in practice. Solar radiation, solar exposure and thermal loads are compared between each alternative, by using the energy simulation tool on existing buildings. Finally, this application method helps architect's design decision in the early design stage. |
