Abstract

A simplified method for measuring the current thermal transmittance is suggested in this paper. First, temporal changes of the sectional temperatures of the building envelope were simulated by the Finite Difference Method. By using these results, the method for measuring the thermal transmittance in a state that closes to steady state was found. The accuracy was examined by comparing with the true values. Finally, the proposed method was used to measure the thermal transmittance of exterior wall of an existing house to confirm the usefulness of this method.
