4A.4 Energy assessment

The Mayor will and boroughs should support the Mayor’s Energy Strategy and its objectives of improving energy efficiency and increasing the proportion of energy used generated from renewable sources.

The Mayor will and boroughs should require an assessment of the energy demand and carbon dioxide emissions from proposed major developments, which should demonstrate the expected energy and carbon dioxide emission savings from the energy efficiency and renewable energy measures incorporated in the development, including the feasibility of CHP/CCHP and community heating systems. The assessment should include:

• calculation of baseline energy demand and carbon dioxide emissions
• proposals for reduction of energy demand and carbon dioxide emissions from heating, cooling and electrical power (Policy 4A.6)
• proposals for meeting residual energy demands through sustainable energy measures (Policies 4A.7 and 4A.8)
• calculation of the remaining energy demand and carbon dioxide emissions.

This assessment should form part of the sustainable design and construction statement (Policy 4A.3).

The Mayor will explore with the government and boroughs the means of extending assessments to include all greenhouse gases.

All development should contribute to improving the integration of land use and transport policy and reducing the need to travel especially by car (see Policy 3C.1). Such issues will not be part of the energy assessment.
