BIM tabanlı BEM Süreci ile Yüksek Enerji Performanslı Bina Tasarımının İlk Aşamasında Üretken Tasarım Yaklaşımı

Nowadays, the design of buildings with high energy performance has increased the importance of decisions made in the early design phases and, in this context, has encouraged the adoption of Building Information Modelling (BIM) based Building Energy Modelling (BEM) approaches. This study investigates the productive design approach integrated with BIM (Building Information Modelling) based BEM (Building Energy Modelling) in the process of high energy performance building design. The proposed method, developed for cold-dry climate conditions, enables architects to generate different building forms, analyse these forms in terms of energy performance, and identify optimised solutions in the early design phase. Using algorithms developed in the Revit-Dynamo environment, firstly, building forms are generated according to form factor and floor area criteria; then, window placements and WWR (Window-to-Wall Ratio) ratios are parametrically defined for facade design. The obtained alternatives were subjected to energy simulations with Green Building Studio and evaluated according to EUI (Energy Use Intensity) values. The design alternatives were visualised so that they could be ranked according to the architect's objectives, and the decision-making process was supported. The findings show that compact forms with low form factor and facade-based window optimisations have a decisive impact on energy efficiency. In this context, the developed framework is an effective tool for sustainable and data-driven building design in the early design phase.
