We can measure the efficiency of the home and then plug a ‘basket of average weather, thermostat & heating system timer settings’ through that model to give a kWh heat demand over a year. ![]() Raw data collected via small sensor boxes is worked on by an algorithm to create multiple real performance metrics: one being kWh pa heat requirement in averaged conditions. In short, the EPC said our works wouldn’t materially impact home running costs or comfort.īefore the results, a short description on what’s being sensed. The EPC didn’t recognise the improved quality of the replacement measures while the desktop software (SAP) underpinning the EPC didn’t value the only ‘new’ insulation measure – party wall insulation – as having an impact. The details are here but key was the works barely changed the dial on the EPC home efficiency rating. The retrofit was ‘light’ – taking out existing insulation to re-install with attention on quality. Through the deployment of sensors collecting real world data, we measured the pre and post retrofit efficiency – how quickly heat leaked out – in 12 homes in Manchester. So what energy bill & energy security benefits can sensing homes offer? ![]() As useful feedback goes, imagine a Doctor waving a doll at a critical care patient asking ‘where does it hurt’? Not completely useless, but hardly deploying all available tools. Smart meters sense energy flows into the home but nothing senses the speed at which heat leaks out or how well heating systems convert gas or electricity to heat. Granular feedback from sensors & data processing helps make sense of the modern world. Emergency hospital entry will see your heart & oxygen levels tracked while sensors will go to work divining signals hidden in various bodily fluids. ![]() The average car has 50+ sensors, a phone 14 and a plane 10,000. First up – accept a single core principle: we now live in a ‘sensed world’.
