| Abstract |
As contemporary design gets more sophisticated and the policies of environment-friendly design have been established, the use of BIM (Building Information Modeling) technology is widely spreading in the current AEC industry. For instance, PPS(Public Procurement Service) announced that public projects that are larger than 50 billion won in total construction costs should apply BIM from the year 2012, which is expected to be applied for large scale projects like super-tall buildings in the future. Unlike the conventional process of making a blueprint, BIM technology is a concept that includes additional information as well as the shape information of a building. However, there are few researches conducted for alternative assessment through open BIM-based energy assessment in the initial planning stage. Eventually, it requires much effort and time to understand energy efficiency to come up with the optimal building alternative in super-tall buildings design. Therefore, this study suggests an open BIM-based design method of super-tall building's envelopes through energy performance analysis. When creating building envelopes of a super-tall building from the initial planning stage, the users can efficiently select the most suitable alternative. |
