This guide will help architects and builders understand the energy performance requirements in the 2006 edition of Part L of the Building Regulations. It explains:
- the background to the changes
- the EU Energy Performance of Buildings Directive (EPBD)
- the Regulations and approved guidance that implement the changes
- designing buildings to meet the new carbon dioxide emission targets
- new standards for work in existing buildings.
It is presented in a concise and accessible format to help you understand the major changes in the Regulations and approved documents, and get up to speed without delay. It draws on BRE's close involvement in supporting the government work in drawing up the new Regulations.
"The changes to Part L are radical and far reaching. This guide is designed to help designers and builders through the maze and to provide clear guidance in achieving cost-effective compliance with the new requirements." From the Foreword by Professor David Strong, MD of BRE Environment and Chairman of UK advisory group on implementation of the EBPD
