Energy Statements

The New London Plan is expected to launch in late 2020 and the sustainable infrastructure section was discussed in the Examination in Public at the end of March. Blewburton will be keeping a close eye on progress, but for now we have summarised the key areas to be aware of in relation to energy and emission in construction.

The policy will still only apply to major developments (over 10 dwellings or 1,000m²), however this doesn’t mean LPAs won’t apply this target to minor dwellings, and the overall onsite reduction in emissions required has not increased from 35% but there are some areas of change.

Zero Carbon Homes and Buildings

  • Residential developments are still required to achieve zero carbon homes
  • Zero carbon buildings will also be introduced meaning non-residential developments will also have to comply
  • As before this only applies to regulated emissions
  • Once the onsite 35% reduction has been achieved, zero carbon homes or buildings targets can be met through a carbon offset payment
  • The GLA recommended carbon offset payment amount will increase from £60 to £95 per tonne of CO2. Some local planning authorities may implement a different price

There may be occasions where exceeding the onsite target of 35% will be feasible, in these circumstances Blewburton can advise on the options available and how these compare to the carbon offset payment.

Be Lean targets

New targets have been introduced to ensure that energy demand is reduced through energy efficient design before the implementation of low and zero carbon technologies.

  • Residential developments will now be expected to achieve a 10% reduction on Building Regulations at the Be Lean stage
  • Non-residential developments will be expected to achieve a 15% reduction, although the GLA has stated that there are some building types where this will not be possible

Blewburton can work with architects, developers and design teams to find the most effective and low cost ways to ensure the new Be Lean targets are met.

Carbon Factors

As of January 2019 the GLA require energy strategies to include SAP 10 carbon factors as well as current figures. This will have a number of impacts:

  • The amount of carbon dioxide associated with electricity will decrease drastically
  • As a result of this CHP will become less favourable
  • And heat pumps will become a much more effective solution

Our energy assessors are experienced in modelling a range of technologies and can provide advice regarding the best way to achieve targets using these new carbon factors.

Other issues

  • The draft plan proposed the introduction of annual monitoring and reporting
  • There will be an increased focus on air quality
  • Energy strategies will need to address demand side response
  • Risk of overheating will continue to require attention
  • Strategies will need to address how developments will be future proofed for zero carbon
  • The expected cost to occupants should be reported
  • Embodied carbon in construction will need to be covered in energy strategies

With further changes to the draft plan likely we will provide further updates before it launches and will be keeping up to date on progress so when it goes live Blewburton will be well placed to help ensure your development meets the requirements in the most effective way.

To get ahead and ensure your developments will be able to meet the new requirements get in touch now.
