RE:FIT LONDON – Making London a resilient, sustainable and resource efficient city.
RE:FIT, or the retrofitting of London’s public sector buildings, is one of the pillars of the Mayor of London’s strategic approach to climate mitigation in London. It is a programme designed to help public sector and charitable organisations achieve substantial financial savings, improve the energy performance of their buildings and reduce their CO2 footprint based on the principle of Energy Performance Contracting (EPC).
The Re:fit programme is a procurement initiative for public bodies wishing to implement energy efficiency and local energy generation measures to their buildings or their estate, with support to assist you in the development and delivery of the schemes. These measures improve the energy performance of buildings. As a result, carbon emissions are reduced and substantial guaranteed annual cost savings are achieved.
The Re:fit framework uses a robust, flexible and tested Energy Performance Contracting approach. Initially developed by the Greater London Authority in 2009, use of the framework is growing, with dedicated teams now supporting organisations across England and Wales. The programme helps by enabling organisations, such as local authorities, schools, universities, hospitals, leisure centres and museums, to implement retrofit projects and achieve large financial savings.

Resources needed

RE:FIT has been funded by ELENA (2,4M £) and the Greater London Authority (0,27M £).
Projects are being funded by the building owners and in some cases by the ESCO.

Evidence of success

By April 2016 the RE:FIT programme has achieved the following:
- 440 buildings retrofitted or in the process of being retrofitted.
- 68,6 Mio £ achieved capital investment (Summer 2015).
- 5Mio £ per annum of energy savings.
- 34,5K tonnes CO2.
Investment amounts range from less than 0,1M £ to over 6,0M £ and energy savings range from 7% to 47% with the bulk of energy savings between 15% and 30%.

Potential for learning or transfer

The RE:FIT programme has won a number of awards in the fields of government and sustainability.
Building on the success of the existing Re:fit programme, the Greater London Authority (GLA) and Local Partnerships (LP), working in partnership with Crown Commercial Service have now launched a third iteration of the Re:fit framework. The new national energy performance contracting framework is intended for use by public bodies throughout the whole of the UK, providing the means to improving the energy efficiency of public buildings and assets through the implementation of energy efficiency, and/or energy generation measures.
The Framework is an integral part of Re:fit and by combining an EPC framework with expert advice and support to public sector organisations, Re:fit cuts costs, achieves substantial guaranteed energy savings, reduces carbon emissions and ensures best practice within the EPC market.
