Quantitative ITT methodology to obtain the thermal bridge heat flow rate in buildings presented. Methodology suitable for determining Ψ-values of any existing building envelope. Excellent agreement found while testing the methodology in the hot box device. Relative deviation in Ψ-values from ITT and from hot box measurements varied from −5% to −36%.
