Lecture explores housing energy performance
The lecture, which took place on Wednesday 19 November in the Rose Bowl, was entitled ‘Bridging the building fabric performance gap’ and saw Professor Johnston examine the concept of the building fabric ‘performance gap’ – the difference between the predicted and actual measured performance of the building fabric of a home (the roof, ground floor, external walls, windows, and doors).
Professor Johnson proposed that it is possible to bridge this performance gap when constructing new homes in the UK. However, this is likely to require careful, well-thought-through and detailed design, coupled with a highly-skilled and educated workforce, alongside appropriate quality control systems.
David Johnson is Professor of Building Performance Evaluation in the Leeds Sustainability Institute at Leeds Beckett University. He has more than 20 years’ experience of applied and theoretical research and consultancy in low carbon housing and is a leading expert in coheating testing and building performance evaluation.
David has secured more than £500,000 of funding from the Technology Strategy Board (TSB) as part of their Building Performance Evaluation Programme to carry out further practical studies in houses after construction and whilst in use by occupants.
The findings from his work are being used by clients, contractors and developers to inform their design and construction practices and help them understand how they can begin to close the gap between design intent and performance.
