  3. Demystifying low carbon retrofit • Existing/operational buildings • Why optimising energy performance is relevant • Low carbon retrofit process • RE:FIT initiative for public sector low carbon retrofits • Optimising performance within private sector

  4. Energy performance is becoming increasingly tangible and increasingly valuable Energy price rises Employee productivity and satisfaction Climate Change Act 2008 80% reduction GHG by 2050 Green Construction Board’s Low Carbon Routemap www.greenconstructionboard.org CSR Energy Act 2011 2018 minimum energy performance targets Customer demand The direction of travel is clear… toward low carbon retrofit!

  5. What cannot be measured cannot be managed • The first step…Data is key • Benchmark performance – gap between current and potential performance • Set target energy savings (carbon or financial led) • Understand potential investment costs • Build the business case • ‘Bundle’ buildings across a portfolio

  6. Low carbon retrofit measures • Heat recovery • Meters • Voltage optimisation • Lighting & controls • BMS controls • Loft insulation • Insulation to pipework • Cavity/solid wall insulation • Draught proofing • VSDs on pumps and fans • Radiator reflector panels • Secondary glazing • District heating • CHP • Solar thermal • Photovoltaic panels • How to begin the retrofit project… 1E Nightwatchman software for PC auto shutdown

  7. RE:FIT is a public sector initiative that guarantees energy savings through low carbon retrofit

  8. The RE:FIT Building Energy Efficiency Programme Energy Performance Contracting approach: The public sector building owner identifies a portfolio of buildings to retrofit, sets a target percentage energy savings and a payback period Insulation Building management technologies Run a mini competition to select an Energy Service Company (ESCo) to carry out the works and guarantee the resulting energy savings Cooling equipment Payback of the investment is guaranteed with the delivery risk transferred to the ESCo with the delivery risk transferred to the ESCO. Low carbon heating RE:FIT allows public bodies to make substantial cost savings, reduce energy bills and the carbon footprint of their buildings

  9. RE:FIT Benefits • An easy to use, free to access framework that is OJEU compliant • Opportunity to make substantial energy and carbon savings, average 28% p.a • Savings are guaranteed • Low payback periods typically <7 years • A tested, readily accessible and constantly updated and improved approach • No access fees and no shared savings • There are no royalty or other costs associated with accessing the RE:FIT Framework, and no sharing of the energy savings benefits it will bring you.

  10. RE:FIT Successes Retrofits completed/near completion on 111 buildings including: • Schools • Fire stations • Police buildings • Hospitals • Universities • Cultural Centres • Office buildings £13.3m investment £2.1m energy bill savings pa The framework is available to all public sector organisations around the UK.

  11. RE:FIT Finance Options • Range of financing options in new Framework • self funding using own budgets or reserves • supplier funding • 3rd party funding • Salix • Public Works Loan Board • Banks • Other public or private sector sources • A mix of the above

  12. Ealing Council RE:FIT • 4 buildings identified including listed town hall and main civic centre • 29% guaranteed energy saving p.a. • Over 1,000 tonnes carbon saved p.a • £1,100,000 investment • 5 year payback – savings remain with Council after this period • 10 month project

  13. Optimising energy performance in the private sector • Some EPC approaches already available • Encompass backlog maintenance issues • Life Cycle Costing provides full evidence to support business cases • Logical and proven process • Supports tenant retention • Enhances reputation, business positioning

  14. A call to action for us all… “With this foundation, we call on the private and public sectors to use their collective knowledge and strength to move the green building agenda forward, knowing that it benefits people and the environment - and their bottom lines” World Green Building Council, The Business Case for Green Buildings, March 2013 http://www.worldgbc.org
