Policy EN9

Ensuring Energy Efficient and Low Carbon Development

Major development proposals will be required to demonstrate how the need to reduce carbon emissions has influenced the design, layout and energy source used, subject to viability. A design and access statement will need to consider the following:


Development proposals, including refurbishment, will be supported where they demonstrate the following, subject to viability:


1. How effective use has been made of materials that have been reused, recycled, are renewable, locally sourced, have been transported in the most sustainable manner, and have low embodied energy;

2. How the design optimises natural sunlight and solar gain, and prevents overheating including providing non-mechanical means of ventilation and opportunities for cooling from tree planting and landscaping.

3. How heat loss from all elements of the building envelope will be prevented;

4. Water efficient measures to reduce demand on water resources, including through the use of efficient appliances, rainwater recycling, water butts and underground storage tanks, where technically feasible; 

5. How developments (dwellings and non-dwellings) have considered on-site renewable, low carbon or de-centralised energy provision, including connection to existing networks, where feasible, in accordance with Policy EN10. 

6. Space for a home office in new homes;

7. Space for cycle storage in new homes and employment sites and, where appropriate showers and changing facilities.

8. Charging points for electric cars.


A site waste management plan which emphasizes waste minimization, re-use and recycling during demolition and construction will be required for major development proposals;


Development should be phased to ensure sufficient waste water treatment capacity is available before development is complete;


The retrofitting of existing buildings so as to maximise opportunities to prevent heat loss from all elements of the building envelope will be supported where it:

  • does not harm heritage assets or their significance; and

  • protects the character of conservation areas.
