CS17: Energy and CO2 Reductions

All new residential developments will be required to achieve the following levels of the Code for Sustainable Homes (Code) as a minimum as and when successive updates to Part L of the Building Regulations become mandatory:

2010 - Code level 3
2013 - Code level 4 once updates to Part L come into effect.
2016 - Code level 5 once updates to Part L come into effect.

All new non-domestic development will be expected as a minimum to achieve CO2 emissions reductions in-line with the Building Regulations Part L. This requirement will not come into effect until successive updates to Part L of the Building Regulations become mandatory:

2010 - 25% reduction in the Building Emission Rate compared to the Target Emission Rate defined by Part L of the Building Regulations (2006).
2013 - 44% reduction in the Building Emission Rate compared to the Target Emission Rate defined by Part L of the Building Regulations (2006) (reductions above 70% can be delivered using allowable solutions).
2019 - Zero Carbon - no additional requirement.

The Council will further encourage all new development or major refurbishment to incorporate energy from decentralised and renewable or low carbon sources. All large scale development will be required to incorporate on-site renewable energy generation, unless it is not feasible or viable or alternative decentralised and renewable, low carbon sources can be identified. The Council will also permit new development of sources of renewable energy generation subject to:

local designated environmental assets and constraints, important landscape features and significant local biodiversity;
minimising any detriment to the amenity of neighbouring residents and land uses; and
meeting high standards of sustainable design and construction.
