This study emphasizes the necessity of sustainable buildings in order to protect environmental resources and reduce pollution by using technological developments. With the building information modeling, which is one of the contributions of developing technology, a three-dimensional simulation of a building project can be created. The annual energy and carbon emissions of the building can be calculated by means of analysis tools. Within the scope of the study, it is emphasized that the effects of carbon emissions on window thickness, window wall ratio, and window shades can be predicted by using Building Information Modeling analysis tools.
