    As we advance towards high-performance buildings, it is becoming necessary to reinforce and extend the role of building information modelling (BIM) to better support performance-based design. To achieve an optimally functioning building that fulfils the need of the end-user and is designed in an environmentally conscious manner necessitates considering energy performance, environmental performance, indoor air quality, lighting, and acoustics. To consider these multiple criteria, use of computer-based modelling tools and comprehensive simulation methods becomes essential. These criteria are typically assessed after the main phases of architectural design of the building, and the knowledge is passed on to the engineers for development of the technical design. During the technical design process, the exchange of data between the design model and a selected building performance aspect may occur. This paper investigates the potential of BIM-based models at the core of providing input data required for performance-based simulations (BPS) to enable iterative multi-criteria assessment towards high performance buildings. A comprehensive literature review of 249 documents was conducted to identify the current state of knowledge and provide future directions for design and simulation tools to better quantify and evaluate the performance aspects. Furthermore, it explains and clarifies stakeholders' current ability, needs, barriers, and potentials in using BIM for assessing building performance through nineteen expert interviews of key BIM stakeholders in Finland.
