BIM SIMULATION A hierarchy of architectural design elements for energy saving of tower buildings in Korea using green BIM simulation By Kweonhyoung Lee and Seungyeon Choo, Kyungpook National University, Daegu, Republic of Korea Academic Editor: Geun Y. Yun Abstract There is a great interest in building information modelling (BIM) and energy saving worldwide. In reality, however, insufficient studies have been conducted on the development of design methods to perform energy performance analysis. Thus, there is a problem that it is difficult to objectively obtain reliability in energy performance assessment of architectural designs such as scale and size of buildings. them in design. To this end, this study analysed the correlation with energy performance using only basic architectural design elements with mass buildings. This has the advantage of establishing more free mass design mass design considering energy performance even if design and main structure are yet to be determined. In addition, the energy performance analysis is considered as a different field from eco-friendly design methods. There is also the problem that low-carbon design methods are more dependent on thermal insulation performance and heating ventilation and air conditioning (HVAC) systems than on original design methods. Introduction Currently, there is a growing awareness of environmental pollution in the whole field of architecture, and there is a continuously increasing interest in green building and low-carbon design methods. According to the World Energy Statistics (Enerdata), it is a fact that the Republic of Korea is urgently required to reduce energy consumption across all industries as the world’s eighth largest energy consumer in 2015. In order to solve this problem, this study aims to develop design methods capable of considering energy performance from the early design stage. Designers are required to intuitively understand the results through energy performance analysis using BIM tools and to reflect Moreover, according to the Korean Statistical Information Service (KOSIS) in Statistics Korea, buildings account for approximately 9.5% of the overall energy consumption. Although the increase in energy consumption showed a decreasing trend from 2010 to 2015, AFRICAN DESIGN MAGAZINE © 41
