CASE STUDY
COVENTRY SPORTS TRUST
I
n 2010, Coventry Sports Trust,
which manages Coventry Sports
and Leisure Centre, appointed
Pureworld Technology Ltd (technology
partner to The Energy Desk) to commission
an energy reduction strategy
to help achieve its target of saving
12 per cent of the complex’s electricity,
gas and water consumption.
With over 900,000 visits per year,
Coventry Sports and Leisure Centre
consumed an estimated 3,127,069
kWh in 2010, equating to 1,679
tonnes of CO2 emissions.
Built in 1966, Coventry Sports
and Leisure Complex comprises two
complexes: one wet-side including
an Olympic size pool, leisure and
teaching pools, two gyms, two exercise
studios, a health suite and a
crèche; and a dry-side complex with
a 10-court hall, a bowls hall, squash
courts and changing rooms.
Pureworld Technology completed an
initial site survey of plant equipment
to establish inefficiencies across the
The energy reduction strategy is predicted to
result in annual savings of £83,160
facility. Following analysis of
the building’s consumption
data, an energy reduction proposal
was produced to outline
the scope of works.
Devising a bespoke solution,
the team carried out the scope
of works, decommissioning
equipment that was identified
as inefficient and retrofitting
upgrading technology where
efficiency could be enhanced.
Integral to any energy reduction
plan is the installation of the
appropriate metering, which allows
monitoring of consumption. An automatic
meter reading system was
introduced to provide accurate data.
The scope of works included the
installation of a new building management
system, optimising the facilities'
boilers and air handling units. Variable
speed drives were also installed onto
the site’s motors to control frequency
and control electrical supply to its air
conditioning systems.
Economical high frequency lighting
was installed in the main sports
hall, including dimmable settings and
sophisticated absence detection technology
to ensure the lighting is on
only when the facilities are in use.
A variety of water conservation
measures were also implemented
including Save-a-Flush bags in WC
cisterns, estimated to save 4,000
litres of water annually. Upgraded
water management controls including
aerated showers and the installation
of a water meter to monitor consumption
helped further reduce water use.
As a result of these changes, the
centre benefited from electricity saving
of 15.29 per cent, gas saving
of 11.3 per cent and water savings
of 15.5 per cent, equating to a predicted
annual saving of £83,160.
