Nottingham Tennis Centre – Nottingham City Council

Nottingham Tennis Centre, operated by Nottingham City Council, is the largest community indoor tennis centre in the UK, hosting events such as the ATP and WTA international Tennis Events. A previous “Proof of Concept” was completed at a nearby site, which resulted in significant energy and carbon savings. Nottingham City Council decided to roll out the CircoSense device across a further 10 sites, including Nottingham Tennis Centre.

The unit was installed at the Tennis Centre in July 2017. The hot water is generated by two Andrews water heaters feeding into a calorifier tank. To allow for accurate measurement of savings, a Bell Flow System BFU-100M Ultra-Sonic heat meter was fitted to the primary pipework of the calorifier tank to assist the measurement and verification process. After the trial period concluded, it was established that the CircoSense3000 had resulted in savings of 41.71% on the fuel used to heat the hot water at the site. In addition, annual savings of 14.38 tonnes were made in carbon savings, with a payback period of 3.26 years.

James Kirkwood, Energy Projects Officer at Nottingham City Council, stated

“Following a successful trial at Victoria Leisure Centre, we decided to install a further 12 units across 10 sites to
replicate the savings achieved during the trial installation.”
