In-Situ Measurement of Building Thermal Resistance with a Plane Heater (OR-16-C053)

In this paper, a new methodology for the field measurement of thermal resistance of building envelope is proposed. A plane heater such as electric blanket is applied to heat one side of the test wall and heat flux transducers are fixed on the other side of wall to measure the heat flux through the measurement section. This could reduce the equipment size significantly and make the installation more easily compared to the traditional hot-box method but still can create enough temperature difference and one-direction heat flux to calculate the thermal resistance of the wall in a relatively short period.
