Imtech and Harrogate District Hospital have recently unveiled a new Energy Centre, following a programme of improvements to the mechanical and electrical infrastructure. The enhanced systems will deliver guaranteed savings of over £15m in the next 25 years (approx. £635,000 per annum) directly benefitting frontline care for the hospital.
Over the last 18 months Harrogate’s Estates Team and Imtech’s engineering teams have been working within the Carbon Energy Fund (CEF) framework to identify, design, specify and install numerous improvements to the mechanical and electrical systems across the hospital, with the guaranteed savings providing not only financial and carbon benefits to the Trust but also a significant reduction in the Trust backlog. These initiatives include:
• Installing a new electrical infrastructure consisting of High Voltage substation and generator network. This has improved the resilience of the electrical systems on site and created more capacity.
• Replacing expired boilers with new high efficiency dual fuel steam boilers combined with a CHP and waste heat composite boiler. With the introduction of a new absorption chiller, the heat can be used during the summer months when less is required, thereby improving the system’s energy efficiency. The CHP system also provides the ability to export electricity back into the Electrical Distribution Network at peak times to maximise savings.
• Replacement of old light fittings for energy efficient LED lighting throughout the site. This provides annual electricity cost savings and patients have benefitted from a more natural, stable light. Also, through taking time to discuss requirements in various locations, the team were able to make 20% of light fittings redundant, as some wards were deemed to be too bright. This project is maintenance free for the next five years due to the lifecycle of approximately 9,000 LED light fittings.
• Imtech’s innovative approach was realised in a solution to utilise waste heat, created by the main system. Usually lost into the atmosphere, this heat is rerouted to the top deck of the hospital car park and reused within the underfloor heating system to de-ice the surface, eliminating gritting costs.
Ensuring the new infrastructure successfully delivers on its guarantees for the next 25 years is the responsibility of Imtech Inviron, the technical facilities management arm of Imtech. Imtech Inviron’s experienced engineers will ensure the continual optimisation of the systems through the implementation of a planned preventative and reactive maintenance regime across the Harrogate Hospital site.
The savings will be monitored constantly over the 25 year period to prove that the savings have been achieved, with continual independent monitoring and verification by the CEF all for the Trust’s benefit.
Phil Sturdy, Deputy Director of Estates, Harrogate & District NHS Foundation Trust commented: “This scheme will support the Trust in continuing to deliver high quality patient care supported by robust engineering infrastructure, capacity to support future clinical developments, reduced backlog maintenance obligations and reduction in energy costs and emissions in line with its Carbon Management Plan.”
Noel Clancy, Managing Director, Imtech Inviron said: “It is extremely rewarding to be involved in this project that will make such a difference to NHS funds for frontline care. Low carbon solutions are a key sector for us and following the successful installation of the new infrastructure services at Harrogate, we look forward to delivering the maintenance regime for the next 25 years. I am confident our specialist team will continue to innovate and ensure the systems are fully optimised to deliver the guaranteed savings.”
Peter Fairclough Director of CEF said “We are also delighted with the success of this scheme, which we see as a template for how significant backlog issues can be addressed by using the CEF financial model and contract, and we look forward to proving the savings work for the term of the contract.”
