A Study on the Model of a Building-Envelope Structural Modification System to Increase Energy Efficiency at the Schematic Design Stage

The purpose of this study was to create a building-envelope structural modification system (BESMS) and an accompanying algorithm that could be used to improve a building's energy efficiency. The proposed system is capable of deciding the optimal structure of a building-envelope. Methods adopted in the study include a review of previous studies and reference literature and, interviews with relevant industry experts. As part of creating the BESMS and algorithm, a five-stage building-envelope design process (BEDP) offering a basis for the BESMS was established. A model using BIM-based design software programs as platforms was proposed as well. The decision-making system for designing the proposed model was developed by combining the FLSs (AI technique) and AHP (decision-making method). Based on these outcomes, components of the BESMS were defined, an inference-deciding structure was determined for each decision-making item as required by the BESMS, related design factors were identified, and the degree of importance was calculated. Lastly, using these results, the model for the BESMS was created.
