초록

Today, there is a growing recognition of environmental pollution worldwide and green buildings and energy saving buildings for green growth are collectively being developed, according to the recent architectural trend. For those reasons, many countries in the world are establishing laws for green growth and modifying design guidelines and green building certification systems,currently. Korean government also announced the national strategies for green growth and set ‘Green Building Certification Systems' and 'Energy Saving Design Standards of Buildings' by establishing the Green Growth Committee directly responsible to the President, according to this global trend. In the domestic green building certification systems, energy performance of buildings are being verified and assessed based on the 'Energy Performance Index Review' of 'the Energy Saving Design Standards of Buildings', but the current verification method is being carried out based on overall heat transfer coefficient of thermal insulators, walls, roofs, slabs, windows and doors and thickness and scale. It is therefore inappropriate to verify energy saving plans from the beginning stage of building design. To get over them, we need to assess alternatives directly using BIM-based 3D Modeling and Simulation and remedy the current verification methods, according to changes in design elements and energy performance. This experiment was designed to model business Facilities using BIM-based Revit Architecture and analyze energy performance of buildings, depending on changes in geography, weather information, direction and facade plan which have been insufficiently verified so far, even though they are closely related to energy performance of buildings, after extracting information of buildings modeled by a building energy performance analysis program, Ecotect Analysis using gbXML extension. After investigating the possibility for simulation verification methods through BIM-based modeling, in this study,change aspects of the energy performance index were analyzed, according to changes in building design elements. Based on the analysis results, this study will suggest supplement points and appropriate verification methods for the future BIM-based green building certification.
