Abstract
This paper explores the challenges and opportunities in integrating Building Performance Simulation (BPS) in the the design of the built environment. While the complexity of building performance and the challenging sustainability target would benefit from a more systematic adoption of BPS, some limitations are still evident. Process-based changes and new business approaches should complement BPS tools technical innovation to better equip practitioners to contribute to addressing future challenges. The paper addresses the barriers to integrating BPS into professional practice, such as the complexity of simulation tools, the need for specialist knowledge and education, and the lack of a shared participative approach to design and building. The potential of BPS to support integrated performance analysis and its role in transforming design practices to meet national and international carbon reduction targets are examined. Recommendations are suggested for overcoming these barriers and promoting a wider adoption of BPS in professional practice.
