London Plan – Key implications of new energy policies
The Intend to Publish London Plan is expected to be adopted imminently. Here we summarise the key implications of the new energy policies:
- Energy efficiency
- Residential: 10% CO2 reduction over Part L 2013;
- Non-Residential: 15% CO2 reduction over Part L 2013;
- Using SAP10.1, instead of SAP2012, enables a slightly relaxed specification.
- Heat Networks
- The heating hierarchy remains where connecting to existing or planned heat network should be prioritised;
- New heat networks should be developed with a single energy centre and be designed with connection points for external connections.
- Solar PV will continue to be encouraged even where buildings achieve the 35% CO2;
- Heat pumps are expected to be the primary energy source for the majority of energy strategies: both for heat networks & individual homes.
- Carbon offset payments
- Increases to £95 per tonne from £60/T and now applies to non-residential as well as residential;
- Use of the SAP 10.1 carbon factors & some heat pump strategies can mitigate this increase.
- Metering and monitoring
- Increased emphasis has also been put on the metering and monitoring of buildings once developed to ensure buildings perform to design standards.
