As of 1st January 2023, all GLA-referable planning applications are required to follow their 2022 energy assessment guidance and spreadsheet.
The main changes are:
The ‘Be Lean’ (i.e. energy efficiency) targets remain at 10% for residential developments and 15% for non-residential, with overall targets at 35%, but the baseline is much improved over Part L 2013 meaning these targets could prove challenging to meet at this point in time. Consideration for further enhancing fabric performance and MEP system efficiencies will be required.
The EUI and space heating demand values are taken largely from LETI’s Climate Emergency Design Guide (a performance specification guidance for achieving Net Zero Carbon buildings) and expressed using GIA.
|Energy Use Intensity (kWh/m2/year)
|Space heating (kWh/m2/year)
|All other non-residential
(Table 4 from the GLA Energy Assessment Guidance June 2022_0)
While the GLA acknowledge that their CO2 reduction and EUI targets will be hard to meet, at least initially, this new guidance will drive London towards its 2030 Net Zero Carbon ambition. This information must be submitted at the planning application stage within the Energy Statement, not submitted post planning. This means there could be implications on the pre-planning programme and Scotch recommends that additional time should be allocated to allow for undertaking the additional modelling and analysis.
