What is an Energy Statement?
When submitting plans for a new development, whether it is residential or commercial, you may be required to submit an Energy Statement alongside your planning application to your Local Planning Authority (LPA) at the very start of the project process.
These statement submissions, which can also be referred to as Energy Strategy Reports, should demonstrate how specific local energy efficiency targets will be met and, as they are governed locally by your LPA rather than nationally, you will need to research into your LPA’s Carbon Emission and Renewable Energy Targets.
As a generalisation most LPA’s requests a 10%, 15% or 19% reduction in Carbon Emissions or energy use, in addition to the nationally set Building Regulations, with exception of the Greater London Authority (GLA) which set out strict new rules, recently updated in October 2016.
Energy Statements within London
The GLA have set out more stringent targets under the ‘London Plan’, which is the overall strategic planning framework for London. This sets out an integrated economic, environmental, transport and social framework for the development of London over the next 20–25 years. Recent revisions to the London Plan dictate that all major developments within GLA will be required to be ‘zero carbon’.
Planning submissions for large projects must include an energy strategy report to comply with a number of policies within the London Plan which cover a range of topics, including the minimising of Carbon Dioxide Emissions.
If ‘zero carbon’ cannot be achieved then a cash in lieu contribution will be sought. The amount due is based on £60 per tonne of carbon dioxide for a period of 30 years based upon The Mayor’s Housing Standard’s Viability Assessment, although this figure can be decided at a borough level.
What should an Energy Statement include?
As the Energy Statement or Strategy Report should be a detailed calculation report on how a development will achieve the Local Authority’s Emissions Target, it should include a calculation of the predicted energy/ CO2 emissions of the development and demonstrate how potential improvements could reduce energy consumption and emissions.
The following information should be included:
Energy efficiency of the building fabric
Baseline annual predicted energy demand of the development (regulated and unregulated)
Baseline annual predicted carbon emissions of the development (regulated and unregulated)
The contribution of each proposed renewable energy technology
Cost information of technically feasible LZC/ renewable technologies incl. CHP
Feasibility of district or community heating
Summary of the benefits of various low energy technologies
The total estimated reduction in the development’s baseline carbon emissions and/or energy demand.
