Abstract
Nowadays, Building Information Modeling (BIM) is the leading technological advance in project management life cycle of constructions. Being able to see post construction phase is one of the non-conventional benefits of BIM of which provides the user to proactively plan the projects. In this study, a retrofit and a reconstruction project were handled in their post construction process to assess their energy efficiency in terms of carbon dioxide emissions and embedded energy results. Generally, structural retrofit basically traces on two principles such as the reliability of the structure and the cost of retrofitting. However, in this study, structural retrofitting was investigated in terms of its energy efficiency compared to a reconstructed building. In this context, a structural retrofit and a new construction with same conditions and dimensions were created with a BIM software and carbon dioxide emission and embedded energy results of these two projects were evaluated. The analysis results indicated that the proportion of carbon dioxide emissions and embedded energy in new construction is higher than retrofitted structure. Consequently, the main factors that cause to higher embedded energy and carbon emission difference between new structure and retrofitted structure were found as concrete and reinforcement steel.
