The Carbon Trust has enabled us to have an exchange of information with other participants in the Carbon Management programme, see what they have done and pick up ideas. It’s been extremely useful and we’ve acquired a lot of helpful information.
Reducing emissions
When the Medway NHS Foundation Trust decided to improve its focus on energy efficiency, its first move was to sign up to the Carbon Trust’s Carbon Management service. From a baseline rate of 13,000 tonnes per year in 2007 the Medway Maritime Hospital aims to reduce its CO2 emissions by 15% by 2010.
The approach
The hospital’s most important project is the installation of a combined heat and power (CHP) system, supported by the installation of a Reverse Osmosis water filtration system. The CHP system is expected to provide a significant proportion of the heating and hot water demand for the hospital and generate sufficient power to cover 75% of the site’s total electrical load. The resulting 1160kW plant, which will cost the Trust £2.9 million to install, is expected to result in annual cost savings of £350,000. It will therefore pay for itself in approximately eight years, and will reduce energy consumption by 11.7%.
The hospital has also fitted dimmable lighting, and installed daylight and motion sensors on lights where appropriate.
Medway plans to spend a total of over £3 million on its combined projects, which are predicted to lead to annual savings of £390,000 by 2011.
Savings at a glance:
- Target: 15% reduction in emissions over three years
- Expected annual cost saving: £390,000 by 2011
- Expected CO2 saving: 5,070 tonnes
- Areas focused on: CHP, lighting, employee engagement
