The UK retrofit challenge • 80% reduction in CO2 emissions by 2050
(Climate Change Act)
• 26 million existing homes• 85% still in existence 2050• 27% total carbon emissions• 500,000+ whole house refurbishments
each year to 2050 (Existing Homes Alliance)
• 100 advanced retrofits during presentation• As much as £10,000,000 business per
working hour• But, economic, social and environmental
barriers need to be overcome…• Green Deal
Green Deal & ECO• Government flagship policy
– now live!
• Key retrofit financial barriers: – up front capital & repayment of work /
return on investment
• Assessment > GD provider & finance > Installation > repayment > Moving on
• Golden rule• Energy Company Obligation
– £1.3bn ECO / pa (3 funding streams)
– Measures / hard to treat
Green Doctor project– Partnership with Groundwork– Engaging up to 500 households
• Retrofit cost effective measures & current cost meters• Provide energy behaviour adjustment advice• Taking 3 sets of meter readings in 12 months • Train resident champions to leave project peer legacy
– New First Wessex Green Living Team• To be brought in house this summer• 1,000 households in programme per annum• Existing homes, retrofit projects, new build• Energy and water efficiency• Communication of strategy
Interactive show home• Partnership with PUSH & Bioregional• DECC fully funded project• 3 multimedia interactive ‘behaviour
change’ and Green Deal homes• Open to public• Using void homes moving from
community to community• FW will rotate one expo for 2 yrs• Opened 14th June in
Eastleigh
Major solar photovoltaic (PV) project˗ Estimated 2.5MW (1,000 homes /
offices / community centres). ˗ Paid for by FIT income over 20
years (pay back year 13).˗ Strong link to social outcomes
e.g. employment. ˗ Average annual electricity bill
saving to residents £150.˗ Annual CO2 savings estimated at
1,250+ tonnes.˗ Tender process complete, Dulas
Ltd. successful.˗ Commencing summer 2013
lasting for 2 years (subject to final budget approval)
˗ Selection of homes.
Insulation projects• Loft & Cavity Wall insulation
– >600 free measures completed in 2012– Now addressing ‘hard to treat’ cavities & lofts– Energy performance Certificates for 100% stock
• Solid Wall Insulation – Relates to >900 pre fab homes in Aldershot (EWI)
and 300 solid wall (IWI) in Portsmouth – Prepare approach for low carbon retrofit zone
in Aldershot (aim for EPC band ‘B’)– Framework for ECO and contractors
• Partnership with LA’s and RSL’s private sector housing • Bridging the financial gap (over ECO)• Employment opportunities!
• Mitre Court, Fareham– 28 leasehold flats requiring over-cladding
Advanced retrofit pilot - Heronwood
20 flats at Heronwood Aldershot•External Wall Insulation•New condensing boilers•New roof with semi integrated PV•Improved air tightness & MVHR•Loft insulation top up•Low energy lighting

Retrofit South East Project
• First use of 4% European Regional Development Funding (ERDF) for retrofit of social housing in 2009.
• £421,000 grant secured for programme of research to build low carbon retrofit capacity.
• ERDF project outputs related to retrofit business assistance provided to 85 SME’s.
• Partnership project:
‘Retrofit South East’ project
To retrofit or build a new community?
“An Ideal setting for a Council estate. This aerial picture of part of the Cranford Road estate shows the neat and airy spacing, with pleasant greens between the rows of houses. Although in complete contrast to the old town, with its splendid examples of Georgian architecture, this essential development is probably as tasteful as a Council estate can be”.
Local newspaper 1950
‘Retrofit South East’ project centrepiece (14 homes)
Solar street community + show home
• Modelled a 77% – 90% reduction in regulated CO2 emissions post retrofit.
• Water efficiency improved by average 16% to 92 l/p/d.
• 85% of waste was recycled off site under SWMP.
• BREEAM domestic refurbishment pilot project.

Working with residents
• 8 months lead in time / consultation period with residents.• Full time community liaison officer appointed.• On-site drop in office available throughout refurbishment.• Decant period was 10-12 weeks.• Community energy efficiency training and 1:1 home visits.
Regional retrofit benefits study • Establish a market worth £460-850m/yr, on top of current RMI.
• Create 4,100 - 33,000 jobs in installation, supply and support.
• Enhance the asset value of regional homes by up to £22.4 billion.
• Liberate over £1 billion a year in energy savings.
• Take at least 360,000 people out of fuel poverty.
• Save up to £80 million on healthcare and up to 3,700 winter deaths.
• Save 3% of total regional water consumption.
• Future-proof homes against climate change impacts.
• Improve regional energy security.
• And cut regional carbon emissions by one fifth!
Through life emissions report release Retrofit v demolition and new build• Comparison analysed over 50 year period.• Advanced retrofit compared with:
– Traditional and timber frame construction– Building Regulations Part L 2010, Code 4 & ZCH 2016
• Emissions considered:– Embodied energy associated with new and existing
materials (‘locked in’), construction processes– The ‘in use’ emissions for heating and power

Through life emissions report key findings
• Advanced retrofitted homes have lower emissions than a new home built to CfSH level 4 and ZCH 2016.
• Considering ‘all in’ costs for similar energy performance:
– Advanced retrofit costs almost 40% less
– A saving of approx £53,000 per dwelling
• Around 20,000 UK homes are demolished every year. If we retrofitted instead:
– 422,500 tCO2/year could be saved,
– Equivalent of 211,000 new homes.
Resident feedback:
“It’s like having a new home on the same plot of land, they are so much warmer, before they were so cold and damp, we even had mould growing. It’s so much better now.”
“ I’ve been running on solar again all day today!”
“The bills are so much cheaper. Bearing in mind what sort of winter we have had, I was really surprised how much I’ve saved.”
• BREEAM domestic refurbishment pilot - Very Good rating
• 75% reduction regulated emissions• Measures applied:
– 500mm loft insulation– Cavity + 32mm IW insulation– MVHR– 2 x 1.35kWp PV (East & West)
• £30,000 on energy efficiency
1970’s End of Terrace, Fareham
• Cost: £30,000 for energy efficiency related works.
• Year 1 & 2 feedback on my home.• Over 400 visitors, many taking action!• Total emissions = 545kg year 1, 270kg

Issues: the town today
• Economic decline• Poor town centre• Disconnected town• Poor public transport links• Poor range of house types & tenure• Lack of employment and business opportunities• Need to protect habitats and species• Population
Future economic roles?
Whitehill Bordon needs to plan for economic growth following withdrawal of MoD by 2014/15.
Potential roles for Whitehill Bordon to focus on:
•Sustainable development & green industries
•Innovation and technology
•Tourism and leisure – South Downs National Park
•Technical skills training
•Employment
£12million DCLG funding received for quick win projects
Revised master-plan proposal map
4,000 new homes
New town centre
Employment
Preservedgreen space
Enhanced areas
High level objectives
• Carbon Neutrality - By 2036 the whole town should be carbon neutral.
• Biodiversity – The target is a net increase in biodiversity.
• Water neutrality – By using existing boreholes and wells and by reducing water usage and wastage we plan a completely water neutral development.
• Transportation – Our target is to reduce car trips to 50% by 2036 in the entire town.
• Economic Development – One local job per new household and jobs to replace those lost by the MoD withdrawal (5,500 in total).
