DRAFT Sustainability Appraisal Report for the Emerging Local Plan ...

11.99 As stated in paragraph 5.102 above given the spatial extent of the areas of influence over
which the identified potential cumulative effects could originate from, it is not considered
appropriate for the CEA to go any further. To do so would be to place a disproportionate
burden on the Council.
Mitigation/Enhancement Recommendations
11.100 This section should also be read alongside Section 11 – Air Quality Mitigation/Enhancement
Recommendations. The following paragraphs supplement Section 11 by specifically
addressing reduction of greenhouse gas emissions.
Climate Mitigation
11.101 Additional reductions in carbon emissions can be delivered using higher ratings of the Code
for Sustainable Homes (CSH) – as shown in Table 3 of Appendix 15. Carbon emission
reductions under Building Regulations and different standards for the sustainable design and
construction are shown in Figure 1 of Appendix 15. Affordable housing is funded by the
Homes and Community Agency that requires homes to be built to code level 3. In addition,
the 2010 Building regulations already include CSH level 3 energy standard. Level 4 of the Code
will be required from 2013 under the new Part L of Building Regulations; therefore
developers could be required to achieve level 4 rating in 2012.
11.102 Developers can be required to provide 10‐15% of the development’s total predicted energy
requirements from renewable energy sources. This 10‐15% requirement will ensure that 10‐
15% reduction in carbon dioxide emissions from the development is achieved through the
supply of onsite renewable energy. Suitable technologies are described in (‘Renewable
Energy’ Interim Advice Note (2010). It is worth to note that some heating technologies,
although beneficial in terms of carbon reductions, can have potentially adverse effects on air
quality (increase emissions of NO x and PM 10 ). It is considered that requiring CSH Level 4 and
encouraging heating technologies like solar hot water or heat pumps will ensure optimal
results in terms of both carbon and air pollution emissions reductions 67 .
Climate Adaptation
11.103 New development will have to adapt to the potentially negative effects of weather patterns
caused by climate change. Design measures to be potentially required from new
development will include:
Sustainable drainage systems to be applied where practicable to reduce the risk
of flood downstream of the development;
Passive building strategies, for instance passive ventilation and appropriate
orientation of buildings to reduce risk of overheating;
Planting trees and shrubs in and around developments at locations where the
vegetation may help reduce overheating in the summer and reduce heat loss in
winter;
Installing water efficient systems and appliances to help conserve water. Also
installing equipment that increases on site self‐sufficiency in water.
