Dalkia has designed and installed a solar thermal array at St Martin’s Junior School in Worle, Weston-Super-Mare.
The work is part of North Somerset Council’s Local Structure Plan, which will see all new buildings generating 15 per cent of their energy requirements using onsite methods of microgeneration.
Further measures carried out by Dalkia include replacing the 40-year old oil-fired heating system with a condensing gas boiler. The firm has also insulated all pipework and installed a Building Management System.
Steve Hodges, energy, policy and project officer at North Somerset Council, said: “When we were looking for alternatives to the school’s old oil boiler system, we knew that we needed to find a strategy that would be environmentally friendly and keep costs down at the same time.
“Dalkia provided us with a variety of options on how to achieve this and we settled on the gas boiler and solar hot water integrated system. This has helped to save money.”
Dalkia claims the array will provide a third of the system’s monthly base load. It also claims the gas heating will deliver carbon dioxide (CO2) savings of over 36,000kg, while an additional saving in excess of 4,000kg is delivered through the solar thermal array. The total potential savings equate to over 41 tonnes of CO2 per year.
