The National Oceanography Centre in Southampton is conserving energy and reducing its carbon footprint – by harnessing the cooling power of seawater.

The centre has unveiled a unique seawater cooling system, exploiting its dockside location to help reduce its electricity consumption.

The system, the only one of its size and design in the UK, was developed by Reading-based Peter Brett Associates, and was shortlisted for a 2009 Edie Environmental Excellence Award. Only a handful of similar schemes exist across Europe.

Seawater is pumped from Southampton's Empress Dock to the NOC's energy centre where it pre-cools water that feeds into the central chiller plant. This is used to support air conditioning systems within the 1,500-room building which houses over 100 laboratories, cold stores, computer server areas and research aquaria. The water is then pumped back into the dock at a temperature no more than two degrees centigrade higher than on intake.

The process will be most effective in the winter months and will reduce the annual electricity demand of the chiller plant by approximately 20 per cent, saving an estimated 117 tonnes in carbon dioxide emissions a year.

The scheme is funded by the NOC's owners, the Natural Environment Research Council. The NOC received the ISO14001 environmental accreditation last year and the sea water cooling system is among several projects aimed at reducing energy consumption at the centre.

NOC Director, Professor Ed Hill, said: "As a major institution in environmental science, it is important that the National Oceanography Centre shows leadership in trying to operate in a more sustainable way. The seawater cooling system is one of a number of measures we are introducing to reduce our environmental impact."

The National Oceanography Centre (NOC) is a new, national research organisation that went live from 1 April this year. The NOC will work in partnership with the UK marine research community to deliver integrated marine science and technology from the coast to the deep ocean.

The NOC brings together into a single institution NERC-managed activity at the National Oceanography Centre, Southampton and the Proudman Oceanographic Laboratory (POL) in Liverpool. The NOC will work in close partnership with the wider marine science community to create the integrated research capability needed to tackle the big environmental issues facing the world. Research priorities will include the oceans' role in climate change, sea-level change and the future of the Arctic Ocean.

The University of Southampton and the University of Liverpool are hosting partners of the National Oceanography Centre. The University of Southampton's School of Ocean & Earth Science shares a waterfront campus with the NERC-operated elements of the NOC, and a close collaborative relationship is maintained at both Southampton and Liverpool. http://noc.ac.uk/
