Today, the demand of sustainable buildings is getting higher. The main purpose of buildings is to provide a comfortable living environment to their occupants, considering different aspects including thermal, visual and acoustic comfort as well as Indoor Air Quality. Decreasing carbon foot print and energy consumption rates while increasing comfort level can help to achieve better living and working environment for building users. This research proposes a framework that aims at improving environmental concerns and evaluating building systems energy using building information modeling during buildings{u2019} design stage by evaluating different alternatives for the installed systems in buildings. The building systems are evaluated considering four main criteria; operating cost savings, total energy consumption per year, Lifecycle cost savings, and carbon emissions. A Multiple Criteria Decision Making (MCDM) technique is applied using Superiority and Inferiority Ranking (SIR) to study different alternatives behavior. Sensitivity analysis is performed to detect the criticality and effectiveness of the different defined criteria that influence environmental concerns and systems energy performance in buildings. A case study is presented to demonstrate the use of the proposed framework
