Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Our Common Future - Brundtland Commission - 1987 People Planet Profit
Construction impacts – Energy UK Energy consumption 1995
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!

Paul Ciniglio - Sustainability & Asset Strategist, First Wessex The Choice An overview of First Wessexs new sustainability strategy and current projects
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 1.MANAGEMENT, MEASUREMENT AND COMMUNICATION 2.ENERGY EFFICIENCY AND CARBON REDUCTION 3.RESOURCE AND WASTE MANAGEMENT 4.TRANSPORT 5.PROCUREMENT 6.CONSTRUCTION DEVELOPMENT AND MAINTENANCE SHIFT status
Green Office Week Used national GOW 13-17 th May to launch The Choice to staff. Road-show between main offices Over 220 staff attended
Office energy monitoring Display Energy Certificates (DECs) EDD:E office electrical energy monitoring -Display screens Environmental Audits of FWPS depots
The UK retrofit challenge 80% reduction in CO 2 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

Paul Ciniglio - Sustainability Strategist, First Wessex 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 SMEs. 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

Modelled a 77% – 90% reduction in regulated CO 2 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. Environmental strategy

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 tCO 2 /year could be saved, –Equivalent of 211,000 new homes.
Resident feedback: Its 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. Its so much better now. Ive 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 Ive 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 1970s 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 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 at www.sunpowerCO2ttage.co.uk
