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 exer- cise 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.

facility. Following analysis of the building’s consumption data, an energy reduction pro- posal was produced to outline the scope of works. Devising a bespoke solution,
the team carried out the scope of works, decommissioning equipment that was identifi ed as ineffi cient and retrofi tting upgrading technology where effi ciency could be enhanced. Integral to any energy reduc- tion plan is the installation of the appropriate metering, which allows monitoring of consumption. An auto- matic meter reading system was introduced to provide accurate data. The scope of works included the installation of a new building manage- ment 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 light-
ing was installed in the main sports hall, including dimmable settings and sophisticated absence detection tech-
The energy reduction strategy is predicted to result in annual savings of £83,160
nology 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 consump- tion helped further reduce water use. As a result of these changes, the centre benefi ted from electricity sav- ing of 15.29 per cent, gas saving of 11.3 per cent and water savings of 15.5 per cent, equating to a pre- dicted annual saving of £83,160.
