Financing and delivering the retrofit revolution ‘ Retrofit South East’ project Paul Ciniglio - Sustainability Manager, Radian
First use of 4% European Regional Development Funding (ERDF) for retrofit of social housing in £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

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 weeks. Community energy efficiency training and 1:1 home visits.
Research and dissemination Retrofit pioneers group established. SME retrofit network set up. Mapping of regional retrofit exemplars. Conferences, seminars and workshops.
Regional retrofit benefits study Establish a market worth £ m/yr, on top of current RMI. Create 4, ,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 cont’d…
Through life emissions report key findings Advanced retrofitted homes have lower emissions than a new home built to CfSH level 4 and ZCH 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.
Project Summary Report release Key learning points and findings Advanced retrofit is expensive but brings significant environmental, economic and social benefits over demolition and new build. Scaling up retrofit regionally has potentially massive benefits. Understand the home, select correct whole house strategy. Follow energy design hierarchy and use proven innovation for more positive carbon value / abatement outcomes. Energy modelling and targets: –rdSAP is inadequate to model true benefits of advanced retrofit. –kg/m2/yr or CO2/m2/yr makes a better target and gives fairer comparison than % emissions reduction targets against baseline.
Project Summary Report Key learning points & findings cont’d… A community liaison officer is essential. Briefing residents on energy efficiency requires a sustained campaign approach. Running cost savings of up to 60% post advanced retrofit are possible (be circumspect on predictions given to residents). Always evaluate the social, economic and environmental aspects of the project. The construction industry needs to up skill and gain knowledge to sell new services - but where is customer demand?
Project Summary Report Key learning points & findings cont’d… Continuity of air tightness and insulation is key – detailing! Ensure good Project Management –sequencing of work, integration of trades and on-site quality control. Beware the hidden costs of retrofit –not only capital costs of work. ERDF / EU project management is very demanding. The Green deal won’t work for C80 advanced retrofit –What proven alternative financial mechanisms are available? Improved resident comfort, well-being and satisfaction is rewarding - Here’s what they said…
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.”
