The Building Regulations Approved Document L: ‘Conservation of fuel and power’ has been amended. From October 2010, work to existing stock, new build, domestic and non-domestic buildings have to significantly improve their energy efficiency standards and reduce their carbon footprint.

What is the 'flat' and 'aggregate' approach; how is a design stage TER/BER carried out; how are shell and core buildings dealt with; what is the effect of solar gain or the energy loss through a party wall?

Presented by the main authors of the Approved Documents and leading experts in the field, this programme explains the key issues and explores methods of compliance.
