Research project The project will contribute to a new method for measuring the heat flux on the building envelope. To better measure the energy performance would significantly improve the quality and contribute to energy efficiency measures.
The project goal is to develop thermography into a method for imaging measurement of the heat flow rate (W/m2) from the building envelope surface. The method enables on site measurement of the heat energy loss (kWh) from the envelope, and its thermal transmittance (U-value). Presently, only single point measurement of the heat flow rate is possible, while no reliable imaging method exist. For this reason, field measurements are rarely performed, and instead one relies mainly on computer simulations. It is well known that computed and measured results often differ significantly.
