Energy and carbon reduction

The development will need to meet the requirements of Part L of the Building Regulations 2013. It will also need to secure 40% carbon dioxide emissions reduction in buildings as compliant with the London Plan. The development should include a detailed energy assessment to demonstrate how the 35% carbon dioxide emissions reduction is to be met within the framework of the energy hierarchy.

  1. Be lean: use less energy
  2. Be clean: supply energy efficiently
  3. Be green: use renewable energy

The development should take account of layout, building orientation, massing, materials and construction techniques to minimise energy consumption.

The energy assessment should include the following details:

  • calculation of the energy demand and carbon dioxide emissions covered by the Building Regulations and, separately, the energy demand and carbon dioxide emissions from any other part of the development, including plant or equipment, that are not covered by the Building Regulations at each stage of the energy hierarchy.
  • proposals to reduce carbon dioxide emissions through the energy ef cient design of the site, buildings and services
  • proposals to further reduce carbon dioxide emissions through the use of decentralised energy where feasible, such as district heating and cooling and combined heat and power (CHP)
  • proposals to further reduce carbon dioxide emissions through the use of on-site renewable energy technologies.

Evaluate the feasibility of Combined Heat and Power (CHP) systems and, where appropriate, examine the feasibility of extending the system beyond the site boundary.

Hounslow Town Centre has been identi ed as an opportunity location for local heat and power networks by the Carbon Reduction Evidence Base for the Local Plan. As the centralised energy networks do not currently exist in the area, the development should make provision to connect to any potential future decentralised energy network in the vicinity of the site if the development does not include a decentralised energy system.

The carbon dioxide reduction targets should be met on-site. Where it is clearly demonstrated that the 35% carbon reduction target cannot be fully achieved on-site, any shortfall may be provided off-site or met by making a nancial contribution to an agreed borough-wide programme.

Flood risk and surface water management

The development site is located in Flood Zone 1 (area with lower ood risk). As the site is of less than 1 hectare a ood risk assessment (FRA) is not required. However the development should incorporate necessary ood resistance and resilience measures, including ensuring that adequate flood defences are in place and maintained through the lifetime of the development.

Air Quality

An air quality assessment is expected and ensures that the development does not exacerbate existing air pollution “air quality neutral” and whenever possible improves air quality. The council’s Air Quality Supplementary Planning Document sets out the information required or air quality assessments and further guidance on air quality consideration.

Enhancing local Skills

We expect the development will deliver construction training and apprenticeships.
