Measured Thermal Performance is powered by our SmartHTC technology. SmartHTC is a new, non-invasive method of accurately measuring the actual thermal performance of a home in a highly cost-effective manner and without the need to vacate the property. Residents can simply go about their daily lives with no effect whatsoever.
It operates through small temperature sensors which are strategically positioned, almost unseen, about the property. They need to remain in position for a minimum of three weeks at any stage over the winter period when the house is being heated (normally between October and April). Alternatively, it may also be possible to collect also collect this temperature data through certain smart home technologies. SmartHTC then gathers hundreds of measurements on internal temperature and energy use, cleverly accounting for variations in weather and the actions of residents themselves.
This comprehensive data is then uploaded to the SmartHTC web interface from which an accurate measurement of the property's true energy performance is produced and a report can be downloaded.
As for cost – each report can cost as little as just £10 per property. Measured and predicted (from energy models) HTCs can be directly compared to assess if a building is performing as expected. A difference between predicted and measured energy performance is known as the "performance gap". HTC measurement should be a key part of any building performance evaluation (BPE).
This means that now, following more than 10 years of development, accurate thermal performance measurement is now affordable and accessible... and that can really drive efficiencies to any retrofit program.
