Abstract. This paper considers the application of accelerated thermal resistance measurement to typical constructions of multi-layer walls of buildings with thermal insulation. It is shown that it is possible to reduce the measurement time considering the results of preliminary modelling. The required calculations for some typical constructions of building walls were made. The examples of simulation results shown in this paper allow to reduce the thermal resistance measurement time by 15-20%. There can be made calculations for other structures of building walls, following the presented method.
