Evaluation of Building Energy Performance Based on Settlement Scale Design Parameters Using BIM Tools

After the settlement textures were designed and constructed, they continue to exist without any change for years, and they have considerable effects on building energy consumption and the natural environment. With the changes in our lives following the COVID-19 global pandemic, employers have adopted working from home in many sectors, and energy expenditures in residences are increasing even more. The decrease of energy usage is a top objective in the design of the settlements from an economic and environmental standpoint. Also, while known energy modeling methods require extra expertise, labor and time in the integration of energy efficient design strategies into design processes, BIM systems have a significant potential in the evaluation of building energy efficiency. In this study, for the comprehensive evaluation of design parameters, different settlement texture alternatives, have been developed and building design parameters determined. These settlement textures were interpreted based on their annual energy consumption. By comparing the results, optimum values were sought for the settlement texture design parameters which are H/W, orientation, building height, and form factor. In addition, energy modelling and simulations were carried out with BIM software, and the use, advantages and capabilities of BIM systems were tested in the energy efficient design for reducing energy consumption. As a result, energy consumption in buildings get changes greatly in regard to combination of settlement scale design parameters. Alternative with form factor 3.00,10 storey, directed to east-west, and H/W 0.5 showed best performance and provided 7% to %17 energy reduction according to different parameter combinations.
