International Journal of BIM and Engineering Science IJBES 2571-1075 10.54216/IJBES https://www.americaspg.com/journals/show/3502 2021 2021 MSc. in Building Information Modeling and Management, Syrian Virtual University, Damascus, Syria Mary Mary Lecturer Professor, Building Information Modeling and Management Master, Syrian Virtual University, Damascus, Syria Naoras Khalil Lecturer Professor, Al-Rasheed International Private University, Damascus, Syria Alaa J Kadi This study addresses the impact of modeling building materials on improving building sustainability by analyzing a case study of a residential building in the Baselia area of Damascus, which has experienced the removal of orchards, leading to negative environmental impacts. The research focuses on evaluating the carbon footprint of the building materials used in the structure and cladding, utilizing Autodesk Forma to analyze life cycle and energy efficiency. The study includes an analysis of the impact of five different building materials on carbon emissions during the stages of production, transportation, installation, use, and disposal. Results show that composite steel has the highest carbon emissions compared to other materials, while wood materials, such as timber frame and mass timber, have the lowest emissions. For internal cladding, the differences between materials were relatively minor. The study recommends selecting building materials with lower environmental impact and enhancing energy efficiency, which contributes to reducing carbon emissions in the construction sector and supports achieving sustainability goals. 2025 2025 48 54 10.54216/IJBES.100205 https://www.americaspg.com/articleinfo/22/show/3502
