by 2050
Zero carbon by
2016
30% less CO2

programme
More numbers…
Buildings = 60% / Homes = 30% of the UK’s CO2 emissions
Work and homes determine much of our impact on the
environment:
waste we generate & resources consumed
55% of timber used in the UK goes into homes, much of it
from unsustainable sources
Water: average 150-180 litres/person/day
Sustainability & Social Housing
•
Soc/Aff Hsg - Still significant numbers – easier to influence
•
Concentrations of poverty in affordable housing – affordable warmth
•
RSLs often operate in communities where poverty and other social problems are
huge issues – community development
•
RSLs often have considerable asset base

What can be done…..
•
by 2020 a 26% reduction
in carbon
•
80% reduction by 2050
•
Housing accounts for 30%
of these emissions
New build
•150,000 Soc Hsg target in 4 years
Refurbishment
•4m + Existing affordable/social units
•25m + Existing homes total
Organisational Footprints
How………?
•
Resource use
• Energy
• Travel
Green new build – planning frameworks
Through their strategic housing, planning, regeneration and transport
roles, local authorities can encourage developers to build houses:
– With high, preferably carbon neutral, energy standards
– With low carbon / renewable energy sources or community energy
schemes
– Using materials with low embodied energy
– In locations and with infrastructure that will encourage walking,
cycling and public transport use
New Build - Sustainable Location
•
•
•
•
•
•
•
•
•
•
Brownfield site/ Empty commercial
Near transport
Near shops
Near Doctors / Dentist
Near jobs (local
employment/investment)
Near Hospital
Flooding issues
(Schools)
Local waste recycling
Local green recreation
New Build - Well Designed & Well Built
Code 3 – 25% CO2 (2006 BR)
Based on points, many options..eg:
• Onsite micro-generation (PV,
Solar thermal)
• Green materials
• Water run off
• Drying space
•
•
•
•
•
•
•
•
•
•
•
•
Radiator TRVs
UPVC windows & doors
Good insulation
Solar Panels
Green transport – eg: cycle racks
Good lighting in house & street
Safe environment
Water meters, spray taps
Low flush cisterns
Drying lines
Tree shading
Use local features

Retrofit measures - Policy
National – “Warmer Homes,
Greener Homes”
By 2015:
Range of energy saving
measures – including solid wall
insulation where possible
Smart meters
Replace fossil fuel heating –
where feasible with renewables
and/or low carbon district heating
Micro gen - Supported by FITs
Preparation for climate change water use, flooding etc
Our sustainability strategy
•
•
•
•
•
•
•
•
•
Reduce environmental impact
Source locally and/or sustainably
Improve awareness
Work with partners
Actively pursue the feasibility of
retrofitting District Heating
Apply Code for Sustainable
Homes principle to refurbishment
Develop Fuel Poverty policy
Adopt cost effective water
management measures
Manage (minimise) waste
sustainably
Retrofit measures - potential
As New Build….
Reduce Demand for the energy through
good design and fabric upgrades.
Increase efficiency of all the machines or
equipment in the house.
Reduce carbon intensity of the energy
you do need by integrating renewable
energy

The full length window replaced by low wall & double glazed window
Existing cavity fill replaced
Internal drylining
Loft - 60mm of spray foam insulation and insulated loft hatch
Solar thermal panels and domestic energy management system
Water efficiency - dual flush toilet, low flow taps, small bath
Energy efficient kitchen appliances
Flood risk mitigation - raising the level of electric sockets to 1m
Sustainable urban drainage, permeable paving enables surface
water drainage
Wildlife garden - shrubs provide protection, nesting sites, food
sources, and flowers to provide nectar and pollen.

current building
regulations
LED Lighting
• Common Areas at Ladybank
• Part funded by the Energy Savings Trust (70% of
materials cost)
• Installation carried out by our own electricians –
completed 2 weeks ahead of programme
• Positive feedback from residents – “brighter and
safer”
• Lamps have very low running costs and guaranteed
for 50,000 hours
Landscape Improvement
Programme
• Total funding of £120,000 split
between 2009/10 & 2010/11
• Designed to shadow the Estates
Improvement Programme
• 8 sites covering all major areas in
Bracknell, and including Harmans
Water, Little Sandhurst & Owlsmoor
Landscape Improvement
Programme
Works include:
• Removal of overgrown shrub borders
• Use of colour in the form of new wave plantings of
perennials
• Mass planting of bulbs for autumn and spring effect
• Sowing of floral meadow on edges of lawn
• Planting of suitable trees (e.g. multi-stemmed birch
• Putting in benches and litter bins
Advantages
• Well being – colour &more welcoming estate entrances
• Reduction of problems caused by littering
• Lower maintenance
• Move towards self-management (e.g. at High Fields)
• Use of plantings which respond to climate change
Landscape Improvement
Programme
Consultation has included:
• Setting up Landscape Forum & discussing
details
• Presentations to all January Estates
Meeting
• Presentation to CIG
• Discussions with adjoining residents &
distribution of information leaflets at all
sites
Signage (estate)
•
•
•
•
•
•
Replacement directional signage in Great Hollands (commencing with
Ringwood, Ullswater, Underwood and Wordsworth) and Ladybank.
Replacement block signs.
Started April 2010.
Notice boards being provided in 82 blocks.
Programme to be completed by November 2010.
Will be maintained by NEAT Team.

Final thoughts…
 Thames Gateway
 2050 goal, 26million homes need to be refurbished to near
zero carbon
 625,000 homes / year …………. 12,000 a week - if we had
started on January 1 2010
 fewer than 100 homes in the country which have achieved this
 Chief Scientific adviser to Government has stated that; “the

retrofit challenge is the most difficult engineering challenge
this country has faced since WWII
Reached the limit of standard measures
Social landlords are leading
Camden - Victorian home, built in 1850, 80% less carbon
(9500 other similar units)
Hyde Housing Association refurbished a terraced house to
80% less carbon (retrofit and replicate)
While these exemplar projects are useful these types of works
are needed on a grand scale
Existing Homes Alliance - 60% less currently costs £20,000 80% less £40,000.
Some potential funding mechanisms – FITs and Pay as you
save
Focus – and Retrofit - is key
Thank you
