The architectural, engineering, and construction industry is one of the major contributors to global carbon emissions and consumes large amounts of resources. A transformation is needed to minimize the environmental damages associated with the industry. This transformation can be realized with the help of environmentally friendly design concepts and sustainable materials. Life cycle assessment can help architects and engineers to determine sustainable solutions. This study investigates the building life cycle assessment, with a focus on building information modeling-based life cycle assessment. It involves analyzing and comparing global warming potential indicator at a different level of detail, specifically, 200, 300, and 400. This research utilizes Autodesk Revit to create and develop models for each stage, and uses two different life cycle assessment tools: One Click LCA and Tally, and three different life cycle assessment databases: generic database of One Click LCA, Ökobaudat database in One Click LCA, and Tally database. The purpose of these tools and databases is to conduct analyses and comparisons of tool behaviors and databases. In this thesis, a kindergarten located in Böblingen, Germany, is used as a case study to perform life cycle assessment analysis. Building elements of the kindergarten have a variety of different building materials, such as concrete, plywood, gypsum board and diverse types of insulation materials. The results of this study show that the change in level of detail does not result in a significant difference in global warming potential indicator. The highest change between level of detail 200 and 400 is 13.53%. Moreover, one of the main findings is the cruciality of the life cycle assessment tool and database selection, since tools and databases demonstrate varying outcomes. Therefore, it is recommended to utilize regional databases and tools.     «
