The Building Research Establishment (BRE) has been appointed to carry out a major new research project to understand heat losses in the 7 million solid-wall homes in Great Britain.

The project, funded by the Department of Energy & Climate Change (DECC), will consider how these walls are performing before and after insulation. The energy-use behaviour of occupants and the accuracy of techniques for measuring heat losses will also be examined.

John Riley, BRE’s director of housing stock performance, said: “Solid-wall homes may be significant consumers of energy and this project will allow more accurate predictions of the energy consumption of these homes and identify the potential for energy savings from solid-wall insulation.”

The study includes a series of laboratory tests and surveys on real homes. These will aim to identify the reasons for differences between the energy savings predicted and those actually achieved.

The project is expected to run for around two and a quarter years.
