CBRE installed the CircoSense technology at the Tower of London as a ‘proof of concept’. The device resulted in 32.5% savings on the cost of heating hot water at the site, with a payback period of 2.75 years. In addition, the CircoSense unit reduced the annual carbon emissions by 9.2 tonnes. Since then CBRE have rolled the technology out to other sites including a Post Office site, a University and are looking at further installations.
