BSRIA has been involved in many recent projects including an independent assessment of the realised performance of low energy / environmentally conscious buildings. This includes projects associated with the Technology Strategy Board’s Building Performance Evaluation (BPE) programme.
The emerging results for more than 50 non-domestic buildings have now been analysed by BSRIA to look at what works well, and when things don’t, why this is the case. It’s always difficult to generalise based on such a diverse building stock, ownership profile, procurement route, supply chain capabilities, and operational approach, but its clear that in many of the buildings there is a significant performance gap between design intent, and realised performance. Analysis of such data is always a challenge. How does one attribute, for instance, any shortfall in performance between the specification, design, construction, commissioning process, and to operational issues such as sub-optimal energy management and / or changes in operating regime such as an extension in occupancy hours.
