Leeds Beckett University sets new heat loss measurement standard

Leeds Beckett University has defined new standards to measure the aggregate heat loss from housing.
Leeds Beckett University has defined new standards to measure the aggregate heat loss from housing.

Two new European Standards have been published – and adopted in 34 countries – as a result of work from Professor David Johnston and Professor Richard Fitton at the University of Salford, in collaboration with European experts.

The standards cover work carried out in a new and existing real-life homes rather than a lab testing environment. The unique approach which allows the pioneering Leeds Sustainability Institute at Leeds Beckett to consistently define global standards for measuring housing performance.  The standards are based upon a testing method (the Coheating Test) that Professor Johnston and colleagues developed at Leeds Beckett University.

The new European Standards will make sure that the thermal performance of housing can be measured and understood in the same way.

“These standards are the result of a decade’s work. It’s a long process but the impact will be incredibly important as governments and housebuilders rise to the challenge of the climate emergency and Net Zero targets,” said Dr David Johnston, Professor of Building Performance Evaluation within Leeds Sustainability Institute, “Leeds Beckett has long set the standards and protocols that the rest of the world follows to assess the aggregate in situ thermal performance of housing. It enables the performance of the building fabric to be tested under the pressures of real-life, revealing any gaps between what designers intended and what was actually built.”

Professor David Johnston has also been accepted as a Committee Member of B/540/8 the Mirror committee for ISO/TC 163 – Thermal Performance and Energy use in the Built Environment.
