Part L England 2013 - A summary of the changes (Version 1)

TRADA image

The Government has a legally binding commitment under the Climate Change Act (2008) to achieve significant reductions in greenhouse gas emissions by 2020 and 2050. Carbon dioxide from buildings, domestic and non-domestic, makes up around 45% of the total UK emissions, primarily from sources which are covered by Building Regulations e.g. space heating and cooling, water heating and lighting. The Regulations therefore, are a primary mechanism for driving a reduction in emissions, by shaping the design of new buildings and affecting improvements to the existing building stock.

This Construction Briefing summarises the changes made in Part L England 2013 (which comes into effect on the 6th April 2014) and explains how they affect TRADA members.

This sheet identifies some of the potential problems which may occur as a result of the transition and the provisions that have been made to make the process smoother, it also examines a number of the criteria which will now be applied to new builds, including CO2 and fabric energy efficiency (FEE) targets.
