  1. Sustainability Impacts of theBuilt Environment Research Collegium in Coastal EcoCities – Session 1 Paul Ciniglio - Sustainability & Asset Strategist, First Wessex

  2. Presentation will cover About me About First Wessex Sustainability and climate change as a driver Environmental impacts – Construction Adaptation to Climate Change The UK / EU retrofit and nZEB challenge First Wessex sustainability strategy – ‘The Choice’ Case studies of low carbon retrofit & new homes Overview of Whitehill & Bordon Ecotown

  3. About First Wessex: Hampshire and Surrey based HA Formed 2007 19,000 existing homes Build around 500 new homes each year Part of Wayfarer consortium of HA’s £25m pa RR&PM spend Customer groups My role

  9. Construction impacts – EnergyUK Energy consumption 1995

  10. Construction impacts – Water Effective rainfall and licensed abstraction People in Hampshire use more water than anywhere else in the UK On average 157 litres/person/day!

  11. What it takes to build 100 houses 1,200m3 Spoil 156,842 Blocks 694,500 Bricks 14,811m2 Plasterboard 2,700m2 Glass 576m3 Timber 300m3 Mortar 2,600m Reinforced Beams 7,500ltrs Paint 5,200m Roadway Construction impacts – Materials

  12. Construction impacts – Waste • The UK produces approx 360 million tonnes of waste (6 tonnes per person per year). • The construction industry accounts for approx120 million tonnes. -10 million tonnes of which are unused materials! -3 million is packaging!

  13. Construction impacts • Pollution • Ecology • Transport • Health & Well-being • Land Use

  14. The ‘strip’ city

  25. New proposal for 2016 • Partnership project with Zero Carbon Hub, Gosport • Helping to inform the new 2016 housing energy standards (Zero Carbon) • Sophisticated testing and monitoring • FW also contributing to Design v As built, Overheating and Comfort • Small development site in Aldershot • Partnership with ZCH & St Gobain linked to DvAB to find optimum solution

  26. Closing the Performance Gap

  27. The ChoiceAn overview of First Wessex’snew sustainability strategy and current projects Paul Ciniglio - Sustainability & Asset Strategist, First Wessex

  28. First Wessex Sustainability Strategy • Strategy and action plan 2013-15 • ‘The Choice’ • Launched in May - linked to Green Office Week • Six headline themes – plus sub policies • MANAGEMENT, MEASUREMENT AND COMMUNICATION • ENERGY EFFICIENCY AND CARBON REDUCTION • RESOURCE AND WASTE MANAGEMENT • TRANSPORT • PROCUREMENT • CONSTRUCTION DEVELOPMENT AND MAINTENANCE • SHIFT status

  29. Green Office Week • Used national GOW 13-17th May to launch ‘The Choice’ to staff. • Road-show between main offices • Over 220 staff attended

  30. Office energy monitoring • Display Energy Certificates (DEC’s) • EDD:E office electrical energy monitoring • Display screens • Environmental Audits of FWPS depots

  31. The UK retrofit challenge • 80% reduction in CO2emissions by 2050 (Climate Change Act) • 26 million existing homes • 85% still in existence2050 • 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

  32. 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

  33. 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

  34. 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

  35. 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

  37. 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 • Work commences in July

  38. Heronwood energy modelling

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

  40. ‘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:

  41. 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

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

  43. 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.

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

  45. 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.

  46. 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!

  47. 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
