Identifying future climate risks and extreme weather in your area How developments and buildings can be adapted so that they are resilient to climate change and extreme weather Principles: — Use local plan evidence base and assessments undertaken for strategic sites — Existing areas affected by extreme weather could be affected more in the future — Areas not currently affected could be in the future, for example: — Flood risk: low lying coastal areas and areas near rivers — Water availability: in catchments that are highly urbanised, have lower than average rainfall and rely on ground water — Subsidence: areas with clay soils — Overheating / Urban Heat Island: buildings in large urban areas, community buildings occupied during the day, south facing buildings (in particular those with only one aspect)

Implementation of adaptation measures in the planning process - opportunities How developments and buildings can be adapted so that they are resilient to climate change and extreme weather There are opportunities to promote adaptation of buildings and developments through: — Planning policy in Local Plans and Supplementary Planning Guidance — Neighbourhood Planning — Influencing design of development during pre-application discussions — Use of planning conditions and enforcement — New build development and refurbishment / change of use Sustainable construction standards include adaptation measures – some developments are required to or voluntarily build to these standards.

Implementation of adaptation measures in the planning process – key players How developments and buildings can be adapted so that they are resilient to climate change and extreme weather When considering how to adapt buildings during the planning process it is important the following parties work together: — Local authorities — Developers — Project Design Teams — Community Groups — Statutory Bodies including EA, Water Companies, Highways Authorities

Promoting Green Roofs in Developments What the benefits of green roofs are in supporting adaptation to climate change, illustrated by Sheffield City Council’s planning policies to drive this agenda locally. CASE STUDY

What is a green roof? Green Infrastructure Source:

Benefits of Green Roofs Wider benefits — Reduce surface water run-off — Improve air quality — Reduce need for heat / cooling — Visual improvement to area — Increase biodiversity Green Infrastructure In Sheffield the topography means that roofs in valleys are highly visible and can make a striking visual improvement Image courtesy of: The Green Roof Centre

Green Roofs in Sheffield – Planning Conditions Green Infrastructure Green roofs are promoted through Climate Change & Design SPD and are applicable to larger developments (10 dwellings or more than 1000sq m internal floor space) — Subject to viability — 80% of total roof area Image courtesy of: The Green Roof Centre

Making the business case for adaptation

Use of UK Climate Projections Making the business case for adaptation UKCP09 scenarios used to prepare for future climatic conditions. Building comfort conditions calculated for predicted conditions in the years 2020 and If the internal temperature exceeds 25°C, it will always remain 2°C less than the external temperature. Conditions will be maintained at required level in 2020 with only a 2% increase in carbon emissions. The building's lowest floor level is set above the 100 year predicted flood level with an additional allowance for anticipated climate change.

(C) Treefellers.co.uk The Hive: Heating 550kw biomass boiler. Regional wood supply source. Back-up gas boilers. Thermal mass. Making the business case for adaptation Why? 1 / 3 of the energy used compared to mechanical cooling. The Hive: Cooling Piped water from River Severn. Used water returned to river with no impact on environment. Why? Biomass only emits around 6.5% CO 2 emissions compared to gas. Estimated that installation of biomass boiler saves £6,043 per year compared solely to gas heating.

The Hive: Emissions Making the business case for adaptation Why? 50% reduction in CO 2 versus Part L 2006 building regulations kg CO 2 / m 2 emitted less per year compared to an average library… That equals approximately £779 saved per year in total. A combination of measures will help to reduce carbon emissions. The building also exceeds building regulations... (C) Free Radio

The Hive: Water Management Rainwater harvesting. Sustainable Urban Drainage System (SuDS). Making the business case for adaptation Why? Reduction in potable water use and cost by 40% compared to an average library. Preventing financial damage to the building by minimising flood risk. (C) Worcestershire County Council
