Map of wind speed variation and wind turbine restriction zones across the Adur District. Solid red lines indicate 100m exclusion zones around buildings (dotted red lines indicate 400m exclusion zone). Red shaded blocks are exclusion zones due to Shoreham Airport flight paths. Note that the majority of high wind speed areas (green shaded) are located within the Sussex Downs AONB, where planning restrictions will apply.............................................................................................................................. 25 Figure 8, Proposed amendments to the CO 2 emissions standards in forthcoming revisions of the Building Regulations (expressed as percentage reductions from current Part L).................................................. 29 Figure 9, hierarchical approach to CO 2 savings favoured by UK government ......................................... 31 Figure 10, Minimum CO 2 emissions reduction standards (reduction on current Part L2006 regulated emissions) defined at each level of the Code for Sustainable Homes ..................................................... 33 Figure 11, Capital cost effectiveness of a comprehensive range of low carbon technologies for a typical domestic property.................................................................................................................................. 37 Figure 12, CO 2 capital cost effectiveness of low carbon technologies for a typical non-domestic property .............................................................................................................................................................. 37 Figure 13 - Mechanically ventilated office used for modelling ................................................................. 41 Figure 14 - Large retail building simulated.............................................................................................. 41 Figure 15 – Energy efficiency improvements required under progressively rigorous improvement scenarios............................................................................................................................................... 44 Figure 16- Improvements in heat loss parameters for progressively rigorous energy efficiency scenarios44 Figure 17, Estimated additional capital cost implications of each of the domestic energy efficiency packages (costs are given per dwelling)................................................................................................. 44 Figure 18, Additional capital cost of delivering CO2 emissions reductions by improvements in the building fabric alone...........................................................................................................................................
