Passivhaus Post Occupancy Evaluation and Proposed BIM-Based Intelligent Model

Passivhaus has been gradually adopted worldwide as the main voluntary building performance standard. While numerous governmental policies and environmental initiatives have promoted the use of low-carbon housing in the UK, the value of Passivhaus has not been fully realised. This paper focuses on UK Passivhaus homes through the perceptions of end-users living in large-scale developments. Case studies are used to obtain feedback on the buildings’ performance in the use phase via questionnaire. All surveyed Passivhaus properties were perceived to be very comfortable during the winter, autumn and spring seasons; however, residents were less satisfied with thermal comfort in the summer. This suggests that the standard needs to continuously evolve to address occupant needs. Digital tools can play a role to achieve this. The study concludes a BIM-based process for post occupancy evaluation to overcome heating and thermal discomfort issues.
