Some significant global problems, such as global warming, depletion of the ozone layer and natural resources depletion, point out that sustainable solutions are critical in the construction sector, as in many other fields. In this context, the Life Cycle Assessment (LCA) method, which enables the determination of the environmental impacts of buildings, comes to the fore. In addition, due to the negative environmental impacts caused by the building sector, the tools developed to create sustainable designs have started to be used. The Building Information Modelling (BIM) method, which uses these tools and is becoming increasingly important, can produce solutions in different ways in design, construction and use processes from an environmental perspective. The decisions, especially in the early stages of building design, are effective for sustainability goals, and the analysis and simulation functions provided by the BIM help the designers to make sustainable design. In this study, it is aimed to to explore and analyse the potential of using LCA in an early design stage using design tools. It was focused on researching and defining the most important aspects of LCA and BIM through a literature review. Thus, the importance of the decisions taken at the early design stages for sustainable designs and the necessity of innovative methods that the BIM method provides to the designer while making these decisions are revealed. The studies highlight the potential of integrating LCA and BIM to make sustainable design decisions early on also indicate the importance of LCA data, level of development (LoD) of the BIM model, and the knowledge of designers on the topics of LCA and sustainable design.
