<p>The BIM (Building Information Modeling) approach represents a systemic and holistic transformation in the development and management of construction projects, requiring significant changes in processes, behaviors and use of related technologies. Behavioral adaptation is a challenge, as there is a human tendency to resist change. However, BIM technology facilitates integration and collaboration between teams and significantly increases control over project development. This article presents a natural and artificial lighting simulation interface for complete projects developed using information models (BIM), promoting interoperability and involving multidisciplinary teams and users. The interface uses game engines, software with high graphics power for architectural and lighting simulations. Its distinctions from existing simulators are in the technical accuracy of its information from projects developed in BIM and in the efficiency of photorealistic rendering in real time in the simulated environment. The application’s initial development focuses on simulating lighting with georeferencing and bioclimatic data, but in the future it may evolve and cover ventilation, air conditioning and people flow. The goal is to promote behavioral changes (both among designers and users), optimizing the use of the BIM platform using game engines and virtual reality to improve understanding, analysis, collaboration and communication, resulting in more efficient and well-functioning projects and works.</p>
