HRH The Princess Royal officially opened the
new £19m Malvern Community Hospital recently.
The new-build hospital uses advanced renewable
and energy efficient technologies, making it one of the greenest
buildings in the country.
Capita Symonds provided building services
engineering and BREEAM consultancy services on the 24-bed hospital
which utilises renewable geothermal energy for heating, cooling and
hot water, and ground source heat pumps to harness solar energy
absorbed by the earth. It also generates low carbon electricity
using highly efficient combined heat and power (CHP) that will meet
a significant proportion of the building’s needs.
By generating its own green power, the
hospital is projected to save £8,700 per year on its energy bills,
and reduce its carbon emissions by 15 tonnes per annum, equating to
the environmental benefit of 1,500 trees.
The new hospital, at Seaford Court, Malvern
Link, includes in-patient and out-patient facilities, x-ray and
ultrasound, day rehabilitation and therapies, palliative care and
visiting mammography and MRI scans. A minor injuries unit will
transfer from the existing hospital, offering increased
The ground source system involves 25 boreholes
and two heat pumps with combined capacities of 125kW for both
heating and cooling. The combined heat and power (CHP) system is a
reciprocating gas engine rated at 33kW of electrical output that
will generate 55kW of useful thermal output for the building and
the ground loop for the heat pump.
Peter Grove, Capita Symonds, says: “The NHS is
responsible for approximately 3% of England’s total carbon dioxide
emissions and has an annual energy bill of over £500 million. To
raise both environmental and cost performance, there is a powerful
need to implement effective carbon reduction strategies such as CHP
and ground source heat pumps. CHP reduces greenhouse emissions
drastically by capturing the heat output that is wasted in
conventional power generation (CHP electricity is around one third
of the price charged by conventional UK suppliers and cuts carbon
by around 20%).”
