Abstract

Reducing energy consumption and greenhouse gas emissions to combat global climate change has become an international necessity. A large portion of energy consumption is attributed to old buildings, with increased operational costs and decreased occupational comfort. These buildings require renovation measures that can be viewed as an opportunity to implement sustainable construction and create traditionally designed buildings based on sustainable construction. This study proposes a combination of building information modeling (BIM) with Design Builder and Meteonorm software to evaluate the environmental impact of renovating buildings during the operational phase. The process involved is demonstrated in a case study application to a typical two-story single-family residential building in Tehran city, in which the building’s materials, weight, and volume are determined using Revit software, and Design Builder is used to simulate the renovation effect on various building components – showing that, by combining the most effective insulation, glass, heating system, and doors, a 15% reduction in energy consumption and 44% reduction in CO2 emissions could be achieved. The study significantly advances knowledge in sustainable building practices by introducing a practical framework for decision-making in environmentally conscious building renovations, focusing on such crucial elements as insulation materials, window glass types, heating systems, and door materials. It also provides valuable insights into the practical implications of weather data for accurate environmental forecasting, emphasizing the methodology's applicability and adaptability to similar contexts, as evidenced by its successful application in a real-world case in Tehran.
