Starting with the Industrial Revolution, there has been a change and development in world history at an unprecedented speed. As a result of the developments in the last fifty years, the emerging needs and the solutions implemented; global warming problem affecting the world globally, significant climate changes, ozone depletion, the danger of depletion of underground resources, increased energy consumption, and environmental pollution have emerged. Researches show that this situation is directly related to the field of architecture and particularly architectural design. To overcome this situation, new architectural design tools and approaches started to be developed. In this context, design tools for massing have been developed for Building Information Modeling environments and the conceptual analysis and simulations have been provided. Thus, the designers have been offered the environment to test their designs with certain conceptual and presumptive inputs and to evaluate their work in the context of sustainability even at the early design stage. From this perspective, the primary aim of this study is to examine the impact of new design tools presented by Building Information Modeling environments on early design decisions in the context of sustainability and to examine the findings. The research questions identified to achieve this aim are as follows: What intensity of physical and cognitive design actions occur in protocol studies? Is it possible to identify any similarities or differences in the context of the distribution of design actions the participants have undertaken within the scope of these working processes? In this context, how do feedbacks provided by the Building Information Modeling environment contribute to or influence early design decisions?
