Comparison of thermal bridges calculate method through typical details in low energy designing

摘要

There are several studies that have investigated transmission heat transfer losses, through building envelopes including thermal bridges. Most of the studies investigate the effect of different calculation and simulation methodologies, such as static/dynamic and 1D/2D/3D. It is essential to minimize heat losses in designing phase in accordance of building energy efficiency. Building envelopes with high thermal resistance are generally typical for low-energy buildings. In this sense thermal bridges impact increases by using of greater thickness of thermal insulation, s mentioned earlier, different measuring methods may be used to quantify building elements. This paper is focused on comparison of thermal bridges calculate method through typical systems details in buildings. The impact of thermal bridges was studied by comparative calculations for a case study of building with different amounts of thermal insulation. The calculated results represent a percentage distribution of heat loss through typical building components in correlation of various thicknesses of their thermal insulations.
