THE THERMAL ANALYSIS OF LIGHT STEEL-FRAME DWELLING HOUSES

Abstract

Charting the loss of heat due to the heat bridge effect of cold-formed steel sections constituting the load-bearing structure is an important part of the thermal analysis of the building system of light steel-frame dwelling houses. The linear heat transmission coefficient, which serves as a numerical definition of the heat bridge effect, may be calculated on the basis of thermo-photos obtained from in situ thermovisual measurements. The parts of the building under examination have also been modelled through computer simulation, which also provided a value for the linear heat transmission coefficient. The satisfactory coincidence of the results of the two test methods served as a basis of the thermal development of the building system with the aid of simulation models.
