Thermal performance testing enables you to receive an accurate measurement of whole house fabric heat loss which is known as heat transfer coefficient or HTC. Using real-world measurements, we can accurately measure the energy performance of any building.
Testing process
Before the measuring can be carried out our testers gather basic building information such as location, floor area, attachment type, heating system and window type. Current energy consumption data is also collated usually through manual meter readings or smart meter data.
Temperature sensors are then located around the house to measure the internal temperature and humidity over a 3-week period. Where smart thermostats are already installed in the property, it may also be possible to retrieve the temperature data directly from the device.
Once the data is collated at the end of the 3-week measurement period, the temperature sensors are retrieved and readings are downloaded.
All the gathered building information, energy data and temperature readings are uploaded to a BTS secure online system from where a Heat Transfer Coefficient will be calculated along with an energy rating. We can also generate a report that can be presented to the homeowner or resident.
Showing the benefits - Where a baseline test was performed prior to energy-saving works being carried out, any rating improvement will show the performance improvement and quality assurance of the works that have been carried out.
