resilient to climate change and extreme weather
Identifying future climate risks and extreme weather in
your area
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
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.
How developments and buildings can be adapted so that they
are resilient to climate change and extreme weather
Implementation of adaptation measures in the planning
process – key players
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.

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

Green Roofs in Sheffield – Planning Conditions
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

Making the business case for adaptation
Use of UK Climate Projections
• UKCP09 scenarios used to prepare for
future climatic conditions.
• Building comfort conditions calculated for
predicted conditions in the years 2020 and
2050.
• 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.
Making the business case for adaptation
The Hive: Heating
Why?
• 550kw biomass boiler.
• Biomass only emits around
6.5% CO2 emissions
compared to gas.
• Regional wood supply source.
• Back-up gas boilers.
• Thermal mass.
• Estimated that installation of
biomass boiler saves £6,043
per year compared solely to
gas heating.

The Hive: Cooling
Why?
• Piped water from River Severn.
•
• Used water returned to river
with no impact on environment.

Making the business case for adaptation
The Hive: Emissions
• A combination of measures will help to
reduce carbon emissions.
• The building also exceeds building
regulations...
Why?
• 50% reduction in CO2 versus Part L 2006
building regulations.
• 45.2 kg CO2 / m2 emitted less per year
compared to an average library…
• That equals approximately £779 saved per
year in total.

Making the business case for adaptation
The Hive: Water Management
• Rainwater harvesting.
• Sustainable Urban Drainage System
(SuDS).
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
Making the business case for adaptation
The Hive: Roofscape
• Pyramid structure; each cone made from
sustainable sourced softwoods.
• Brings in natural daylight and ventilation.
(C) The Hive
• Spatial character.
Why?
• The change from
steel/concrete design to
timber has saved 2,000
tonnes CO2.
