Building Performance Evaluations (BPE) consists of a whole building assessment, following a Post-Occupancy Evaluation (POE) survey, to identify the performance gap between the design aspirations and the actual operating performance of a building. The evaluation considers multiple aspects of the asset, covering energy efficiency, maintenance, occupant health and well-being, safety and public liability. The results of the BPE can be used to inform building management policies and procedures, as well as potential remediation measures, resulting in improved efficiency and reduced operational costs. Further to the increased efficiency, enhancing building health can benefit occupants through improved indoor environmental quality, leading to increased productivity, reduced incidences of Building Sickness Syndrome and overall improvement in occupant comfort and satisfaction.
To comprehensively assess the existing condition and performance of a building, a Post Occupancy Evaluation (POE) is conducted at the outset of any BPE. The POE includes an evaluation of occupant behavioural patterns, such as hours of occupancy, as well as gathering feedback from occupants themselves to highlight any recurring issues. Occupant feedback surveys are used to gather large data sets covering occupant satisfaction, with subsequent interview style surveys providing a deeper insight into observed trends. Surveys and interviews cover topics such as thermal comfort, productivity, Building Sickness Syndrome (recurring headaches, itchy eyes etc.), light Levels, acoustic comfort and access to facilities.
