Leeds Beckett sets new global standards to reduce heat loss in housing

Leeds Beckett University’s ‘real-world’ research has defined new standards to measure the aggregate heat loss from housing – a crucial lever to meet the challenge of Net Zero.

Two new European Standards have been published - and adopted in 34 countries - following work led by Leeds Beckett’s Professor David Johnston, together with Professor Richard Fitton at the University of Salford, in collaboration with a wide range of experts from across Europe.

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.

Dr David Johnston, Professor of Building Performance Evaluation within Leeds Sustainability Institute, said:

“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.  

“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.

The Leeds Sustainability Institute is a unique multi-disciplinary team which combines an understanding of building science, the way people behave, field work and analysing big data.

The unique team and approach informs sustainable building policy on a local and global scale. The institute has won 10 Government projects worth over £4 million over the last 8 years, relating to energy in buildings.

The strength of Leeds Beckett University’s partnership work has been recognised by the fourth national Knowledge Exchange Framework – with the University placed in the top 20% of universities in three categories.

Notes to editors

The two standards are as follows:

  • EN 17887 1:2024 Thermal performance of buildings — In situ testing of completed buildings — Part 1: Data collection for aggregate heat loss test.
  • EN 17887 2:2024 Thermal performance of buildings — In situ testing of completed buildings — Part 2: Steady-state data analysis for aggregate heat loss test.

The purpose of these two new European Standards is to provide a test method (Part 1) and an analysis method (Part 2) for measuring the aggregate in situ heat loss from a building.

The test method is applicable to both newly built and existing domestic scale buildings.

The test and analysis method can be used as a sample confirmation methodology for large volume production, confirmation of prototypes, confirmation of the performance of particularly significant buildings and potentially as a diagnostic tool to identify the indicative performance of individual elements within a building and inform further investigation and action.

In addition, Professor David Johnston also contributed to the development of the following two new related European Standards (EN), which have just been published:

  • EN 17888 1:2024 Thermal performance of buildings — In situ testing of building test structures — Part 1: Data collection for aggregate heat loss test.
  • EN 17888 2:2024 Thermal performance of buildings — In situ testing of building test structures — Part 2: Steady-state data analysis for aggregate heat loss test.

The Standards will be implemented by the national standardisation bodies of the following 34 countries: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
