Post completion and early occupation building performance evaluation
Closing the gap between design aspiration and as-built performance in a Code level 5 housing development in the UK.
The study aims to broaden our understanding on the energy performance of low-carbon homes and close the feedback loop between design aspiration and post-construction performance.
The study will focus on three basic objectives:
To identify any deviation from the design intent and map the initial occupants’ reactions, the BPE study was organised in two key stages covering the Design and construction phase as well as the Post-construction and early occupancy phase of the new homes.
The difference between design aspiration and as-built performance was highlighted by most of the study elements and the findings were found to be correlated to each other and passed through the different construction phases. The main findings were mostly related to the difficulty of the contractors to engage with new materials and technologies, complications in the communication between the different project parties, lack of proper system commissioning and inadequacy of the induction process.
It is vital that these evidence-based lessons on the as built performance of new low carbon housing are taken on board on an iterative basis and embedded into knowledge management systems of councils, developers, house builders, designers and equipment suppliers.
