Carbon and energy reduction
Trust following competitive tenders. As well as providing the required technical expertise, the company guaranteed minimum savings for the duration of the 15-year contract. CHP systems are at the heart of NDHT’s strategy, and Kevin Ward believes the potential for CHP systems is ‘huge’, as the energy savings benefits ‘can and do make a dramatic difference for Trusts moving away from steam’.
Solar panels and new lighting At the North Devon District Hospital (NDDH) in Barnstaple an 800 kW CHP system is currently being installed, along with 250 kW solar panels on the roof. A lighting replacement programme is also underway, and so far some 2,000 LED light fittings have successfully been installed, and a further 1,000 LEDs are now being fitted. At the process’s outset, the Trust had some concerns over logistics, and the impact upon patients, but work has gone very smoothly, with minimum disruption. At the three other sites biomass boilers, solar panels, and replacement lighting programmes, are also underway. With no gas supply, Holsworthy Community Hospital is solely reliant on electricity and oil. The new biomass boiler will mark a significant step change, and offer a more resilient solution. The Trust
About Cynergin
Founded in 2000, Cynergin is ‘one of the UK’s leading consultants and energy services companies’. It specialises in delivering ‘performance-based contracts that offer guaranteed reductions in energy consumption, and carbon emissions, and improved operational performance, on the estates of large public sector organisations’.
also ensured that the pellets for the boiler could be locally sourced.
Holsworthy Community Hospital is also installing 35 kW of solar panels, and renewing its oil fired boiler, to give it an emergency back-up. A similar project is underway at South Molton, where, in addition to a biomass boiler, the hospital is installing 50 kW of solar panels and replacing lighting. The NDDH Trust has already started to see the benefits. Since January, across the four sites, the lighting replacement programme has saved £46,000, and 174 tonnes of carbon, and the solar panels, £15,000. The biggest savings are, however, yet to come. When the CHP system at the NDDH site – currently two-thirds of the way through the installation process – is commissioned, Kevin Ward expects the hospital to realise annual savings of £300,000 to £400,000.
Enhanced reliability
He added: “Not only do we have a more reliable and efficient addition to the infrastructure for each site, but when all the technologies have been installed we will have more resilient systems thanks to Cynergin, and expect to be saving £600,000 to £700,000 annually on our energy costs.” Logistically, the lighting programme has been the most challenging, but Kevin Ward is complimentary about the collaborative working practices, and Cynergin’s project management, as well as the work of the Trust’s own Capital and Facilities Team.
Meanwhile, of the importance of internal communication to the replacement programme, with the Trust communicating to staff the reasons for the lighting replacement, its benefits, and how it would put the hospital ‘on a more solid footing’ for the next 10-15 years, he said: “It was important that everyone bought into the lighting project and understood the benefits. The nursing staff helped with

access, particularly in ‘live’ areas, and patients were moved only when necessary, so as to minimise disruption.”
Data capture
The project partners worked with Salix Finance to secure funding for the energy- saving projects, and found Salix’s compliance tool useful in capturing data and information on the savings that could be generated, the associated technologies, and the paybacks. The estimated savings were calculated by Cynergin, with an assessment of the project business case and savings calculation methodology undertaken by Salix Finance. Finance of £2.8million was sourced from Salix Finance, with the Trust funding the balance; the total capital outlay for the EPC projects was £4.6 m. The projects at NDHT are all on schedule. Kevin Ward says he attributes this to the Trust’s strong relationship with Cynergin, which supplies regular reports and holds weekly meetings. NDHT is considering further projects for the future, and says it and hopes to continue working with Cynergin.

Yeovil Hospital Yeovil District Hospital in Somerset is an excellent example of what hospitals can do proactively to optimise their energy management. Keen to significantly cut its energy bills and reduce the hospital’s carbon footprint, by ‘spending to save’, Yeovil District Hospital NHS Foundation Trust entered into a 15-year EPC contract with Cynergin to introduce new technologies. These both ensured that it could meet its operational and environmental obligations, and delivered more robust systems. Like many hospitals, Yeovil District
