Policy 5.2 of the London Plan requires each major development proposal to submit a detailed energy assessment.
The purpose of an energy assessment is to demonstrate that climate change mitigation measures are integral to the scheme’s design and evolution, and that they are appropriate to the context of the development.
The GLA provides guidance for developers and their advisers on preparing energy assessments to accompany strategic planning applications. Each assessment is required to demonstrate how the targets for regulated CO2 emission reduction over and above 2013 Building Regulations will be met using the Mayor’s energy hierarchy.
As outlined in the Sustainable, Design and Construction SPG (to be published in April 2014), from 6 April 2014, the Mayor will apply a 35 per cent carbon reduction target beyond Part L 2013 of the Building Regulations - this is deemed to be broadly equivalent to the 40 per cent target beyond Part L 2010 of the Building Regulations, as set out in London Plan Policy 5.2 for 2013-2016. This target will apply to all Stage 1 applications received by the Mayor on or after 6 April 2014.
To allow developers time to transfer to the new SAP / SBEM modelling software, Stage 1 applications received by the Mayor between 6 April and 5 July 2014 (inclusive) can demonstrate compliance with either the new 35 per cent target beyond the 2013 Building Regulations or the 40 per cent target beyond 2010 Building Regulations.
This update to the last version of the energy planning guidance (published in September 2013) reflects the new Part L 2013 of the Building Regulations which comes into force from 6 April 2014.
