A new calculation method for deriving easy-to-use equations for the simplified calculation of non-repeating thermal bridges is presented and tested on several constructional variants of a common Central-Europe building type. Through the identification the main parameters affecting the difference between the one- and multidimensional heat transfer coefficients of facades their number is reducible. The method’s accuracy compares favorably to current calculations. A new formulation is introduced for the calculation of the total heat transfer coefficient of the external thermal envelope incorporating the proposed simplified thermal bridge calculation method and the window’s in-situ heat transfer coefficients.
