Renfrewshire Council Estate – 88 Sites

Renfrewshire Council have in place a Carbon Management Plan, which sets out their target to reduce carbon emissions by 19,389 carbon tonnes by the end of financial year 2019/20, which equates to a reduction of 36%. To meet this target, the Council looked for ways to lower carbon emissions across their property portfolio.

An initial trial was carried out at Langcraigs Primary School, where the CircoSense device successfully reduced hot water costs and lowered carbon emissions at the site.

For this trial installation, CircoSense collaborated with the Strathclyde Eco Innovation Unit (SEIU) at the University of Strathclyde, who carried out an independent and rigorous testing regime to verify the level of energy savings made.

Following this successful trial period, additional installations were carried out at another five sites, where the CircoSense device continued to provide significant savings.

These installations then led to a larger order for 77 units across the Renfrewshire Council Estate. This roll-out occurred across April and May 2016, with the non-invasive installation completed in less than a day per unit.

Using externally verified measurements, it was determined that there had been an average of 38% savings on hot water costs across the sites, with an average payback of 3.8 years.

In addition, there was an average reduction of 12.3 tonnes per annum per site, which equates to a total of 1,082 tonnes of carbon reduction across the portfolio per annum.

Craig Thorpe, Corporate Asset & Energy Manager at Renfrewshire Council, stated:

“I’m delighted to say that we can see the reduction in the gas consumption reflected in the bills, and that we’ve had that reduction in pounds and pence, which we’re absolutely delighted at.”
