Legislation & external links

Improving the energy performance of buildings and cutting carbon emissions has been a key focus for the Government in recent years. The target is to build zero carbon homes only by 2016 and achieve a national 80% reduction in carbon emissions by 2050. Changes to Part L Building Regulations came into effect in 2010 and required windows to have a U-value of no more than 1.6, the equivalent to a ‘B’ energy rated window.
