MODEL STUDY OF DESIGN COMPONENTS FOR ENERGY-PERFORMANCE-BASED ARCHITECTURAL DESIGN USING BIM LOD 100

One of the biggest global issues at present involves the search for measures to conserve energy and to combat climate change.Because of an increase in natural disasters and energy use,architects and engineers have been focusing more on creating green buildings with low-carbon designs.Building information modeling(BIM)is used to record all of the data related to buildings from the early design stage.This information can be used to respond to energy simulation feedback and to accommodate changes that may be necessary during the design developments.To mitigate greenhouse gas emissions and to conserve energy in the buildings,the application of a BIM-based low-carbon design technique is required from the early design stage.However,the existing research is limited to sub-segmented topics;therefore,it is difficult for designers to establish a rank grade for a low-carbon design technique that is required for application in design planning.In this study,we attempt to analyze the rank grade and the correlation among design components that affect a building’s energy performance.We selected tower buildings for the experiment,as they consume a massive amount of energy and have a large impact on the surrounding environment.We analyzed the values that resulted from different shapes,scales,slenderness ratios,window-to-wall ratios,and solar orientations of the tower buildings.Then,we identified a correlation and rank grade among different design components.Architects can maximize energy performance efficiency by considering and applying the rank grade of a low-carbon design technique during design planning.In addition,the development of guidelines for green BIM would reduce confusion in the decision-making process and design modification during the stages of design development,which would then minimize the cost.Furthermore,it is expected that this study can be used to create a database for the realization of green buildings.

An Approach to Share Architectural Drawing Information and Document Information for Automated Code Checking System

The purpose of this study is to suggest a way of optimized managing and sharing information between standard architectural drawings and construction documents in Korea architectural industry for automated code checking system by linked STEP and XML. To archive this purpose, the authors have analyzed current research and technical development for STEP and XML link and developed a prototype system for sharing information between model based drawings and XML based construction documents. Finally, the authors have suggested practical use scenario of sharing information through linked STEP and XML using test case of automatic code checking. In the paper, the possibility of constructing integrated architectural computing environment through exchange and sharing of drawing information and external data for the whole building life-cycle, from the conceptual design stage to the construction and maintenance stage has been examined. Automated code checking through linked STEP and XML could be enhanced through col-laboration business, more completed code, improved building performance, and reduced construction costs.
