DECC commissioned BRE to undertake research to improve understanding of the performance of solid wall properties in the UK housing stock and the effect on energy post-insulation.

The first output of this research project is a literature review of existing research and knowledge on Solid Walls and Solid Wall Insulation in the UK and other countries, where relevant. The literature review considers:

• Heat loss measurement and calculation methodologies
• Predicted performance compared to actual energy savings
• Occupant behaviour
• Unintended consequences of solid wall insulation
• Heritage and conservation
