Case Study: CCC Buildings

County Council Owned Buildings

Cambridgeshire County Council sets out to lead by example by adopting the Re:fit framework to increase energy efficiency, reduce CO2 emissions and improve the condition of its buildings. 

The estimated potential of this scheme is to deliver 1.2 million tonnes of CO2 savings over the lifetime of the project. Cambridgeshire County Council’s Re:fit project is available to schools and public sector buildings across the county. 

The Council commissioned Local Partnerships in May 2014 to develop an energy performance contracting programme, which provided guaranteed energy-efficiency savings.

 Local Partnerships is supporting the Council in delivering its Re:fit project:

  •  It helped to scope the project through the tendering phases to appoint the energy service company Bouygues Energies & Services via the national Re:fit procurement framework
  • It is providing quality-assurance reviews of the technical documentation produced by Bouygues and the analysis of the Investment Grade Proposals to help deliver the next phase of the installations.

“Local Partnerships gave us confidence . . . by guiding us through the Re:fit procurement process, offering professional support and advice and asking challenging questions about issues we hadn’t even thought about. Without their support, the procurement process could have been a lot more stressful and we may not have achieved the goals we set for ourselves.”

CCC encompassed a number of Energy Conservation Measures (ECMs) across seven of its buildings.

Solar PV arrays: A comprehensive engineering investigation concluded that they could install seven solar arrays, at a capacity of 183kWp, creating financial benefits of more than £30,000 per year.

LED lighting upgrades and controls: There was a significant amount of inefficient lighting within the buildings, particularly within the building’s circulation areas, such as stairwells, toilets and corridors (both front of house and back of house), and office and staff rooms. The light sources in these areas consisted of various types of fluorescent fittings and in most circumstances have been replaced on a one-for-one basis with a more efficient LED equivalent. There are rooms, however, where fittings have been rationalised to allow for sufficient light levels at lower energy use. Savings of more than £10,000 and over 43 tonnes of carbon per year are expected.

 Insulation: Exposed uninsulated pipework can generate high surface temperatures. This wastes energy and cost, via wasted utilities, and can have detrimental maintenance effects on other plant equipment (shortening the design life of electronic components). This is also a health and safety risk if touched, therefore a range of valve jackets and pipework insulation have been retrofitted to exposed plant.

 Building Management System (BMS) optimisation of controls and monitoring: Issues were identified with the setup of the previous systems. The buildings have been set up to operate at optimum energy efficiency and controls established so that these optimum conditions persist throughout the payback period.

Energy efficiency and financial savings through Re:fit

Re:fit is a procurement framework and support service available to all public sector organisations in the UK. Since 2009 it has been helping organisations to deliver “spend-to-save” environmental retrofit projects that both improve their buildings and, importantly, make substantial guaranteed financial savings.
