The London Plan – Zero Carbon

The Mayor of London has committed to run London on 100% clean energy by 2050, outlined in Chapter 5 of The London Plan; this has led to a number of developments to Building Regulations Approved Document Part L.

The London Plan – Zero Carbon

Policy 5.2 of The London Plan requires all major development proposals to submit a detailed energy assessment, and seeks to reduce the built environment CO2 emissions, in accordance with the following Energy Hierarchy:

Be Lean

The ‘Be Lean’ stage requires buildings to use less energy, for example, improving fabric efficiency, air permeability and to ensure adequate levels of daylight are sustained.

Be Clean

The ‘Be Clean’ stage requires that energy is supplied through efficient methods, such as investigating opportunities for connecting to existing district heating networks and utilising combined heat and power (CHP) systems.

Be Green

The ‘Be Green’ stage relates to renewable energy, and the use of innovative technology in buildings. These should be appropriate to the building and function efficiently in the real world.

How can Stroma help?

Stroma Tech provides a fully supported service to assist in achieving the Zero Carbon requirements of The London Plan, and to help to comply with climate change policies. With in-depth knowledge of the differing requirements of each borough, we can advise on the best approach to minimise carbon offset payments.

Energy Statements and Feasibility Assessments

Our Energy and Sustainability Statements outline the most suitable and cost effective solutions for reducing carbon dioxide emissions and the integration of low and zero carbon (LZC) renewable energy technologies.

A typical statement includes:

  • Predicted annual baseline energy consumption and CO2 emissions
  • A review of the energy efficiency of the building fabric
  • A technical appraisal of the heating, ventilation and lighting
  • LZC feasibility – impartial advice and predicted contribution and cost savings
  • Projected savings against each stage of the Energy Hierarchy

  • Air Tightness Consultancy

Carbon Offset payments

Carbon Offset Payments are a cash in-lieu payment for the remaining CO2 emissions for the development.

The London Plan stipulates a cost of £60 per tonne over a 30 year lifetime for each dwelling: (£60 x 30 years = £1,800 per t.CO2)

Cost calculated at planning stage will likely be incorporated into Section 106 agreements.

There is some variance between boroughs and they can stipulate a local rate – Borough’s own policy will apply.

Zero Carbon Targets

From the 1st October 2016, all major new-build residential developments in London will need to achieve a ‘zero carbon’ standard, followed by non-residential by 2019. Between the 1st October and the introduction of the Zero Carbon targets, major non-residential developments will still be required to achieve a 35% reduction in CO2 emissions.

Carbon dioxide emission reduction targets are set as minimum improvements over the Target Emission Rate (TER), outlined in the Building Regulations.

Residential Buildings

Year Improvement on 2010 Building Regulations
2010 – 2013 25% (Code for Sustainable Homes Level 4)
2013 – 2016 40%
2016 – 2031 Zero Carbon (> 35% & Carbon Offer

Non-residential Buildings

Year Improvement on 2010 Building Regulations
2010 – 2013 40%
2013 – 2016 As per Building Regulations (Retaining 35%)
2016 – 2031 Zero Carbon (> 35% & Carbon Offer
