Annual Report and Accounts 2012/13 - Royal Devon & Exeter Hospital

2. Our Trust Royal Devon and Exeter NHS Foundation Trust 57
Annual Report and Accounts 2012/13
Absorption chillers
It is anticipated that the current
cooling load of the hospital will rise
significantly over the coming years.
Absorption chillers use heat to drive
a refrigeration process and are ideally
suited to run in conjunction with
waste heat recovery system boilers as
described above. Absorption chillers
provide a chilled water supply at a
constant rate and would be used to
maintain the base load of the hospital
cooling system.
Action – To carry out a feasibility study
in conjunction with the CHP project
mentioned above. No estimated cost at
this stage.
LED and low energy
lighting
District heating
system schemes
The Trust is currently participating in an
initiative with Exeter City Council and
the University of Exeter looking at the
potential for both the Wonford and
Heavitree hospital sites being part of,
or hosting, a district heating scheme. A
feasibility study has been commission
by the Council and the outcome looks
favourable towards a scheme that
would result in massive cost savings to
the Trust and a carbon saving of circa
16000tCO2.
Water Consumption
The Trust is actively tackling water
leaks and has recently stopped leaks
losing 4.5m3 of water per hour.
Most of the Trust’s fluorescent lighting
will be replaced by LED lighting
wherever possible.
As well as reducing the electrical
load, the emergency light fittings
are maintenance-free, so will reduce
revenue costs.
Action – The first priority is E-link
corridor. Refurbishments and new
builds will be specified to have low
energy lighting and controls as
standard.
