  27. 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

  28. 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

  29. 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

  30. 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.

  34. Retrofit South East Project Paul Ciniglio - Sustainability Strategist, First Wessex

  35. ‘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:

  36. 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

  37. ‘Retrofit South East’ project centrepiece (14 homes) Solar street community + show home

  38. Environmental strategy • 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.

  39. Continuity of insulation & air tightness Before After Air pressure test Before, REEMA panels After retrofit EWI -100mm

  40. 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.

  41. 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!

  42. 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

  43. Through life emissions report cont’d…

  44. 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.

  45. 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.”

  46. 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

  47. 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 yr 2. Running costs = £319 year 1, £274 yr 2. ASHP £230 year 1, £190 yr 2. Credit with FIT income +£511 year 1, + £658 yr 2.  Water consumption 68 l/p/d. Further details atwww.sunpowerCO2ttage.co.uk
