Influence of thermal bonds when evaluating the energy performance of buildings can be included in the calculation approximately by means of a surcharge on the effect of thermal bonds or precisely by using specific linear heat transmission coefficient for thermal bonds between structures. The article presents a comparison of the two options in the energy performance of a particular building, the specific amount of heat for heating the building of a brick passive house based on the foam glass.

Composite Walls

Two thermal experiments of light gauge steel-framed composite walls with slotted studs and with external thermal insulation layer were carried out in the lab of combined energy consumption test board for components of building envelope in school of municipal and environmental engineering at Harbin Institute of Technology (HIT). The lab is one of the key laboratories of Ministry of Housing and Urban-Rural Development of the P.R.China. The method of thermocouple temperature measurement has been used. The heat transmission coefficient and the measuring point temperature of composite wall have been deeply investigated, which is finely compared with the FEA model results at the same time. Two conclusions can be drawn from the test: web slotted studs can reduce heat loss of the light gauge steel-framed composite walls obviously, thus it can weaken the thermal bridge effect of the location in stud part, so it can improve the thermal insulation properties of the composite walls significantly; the composite walls’ heat transmission coefficients of the two test schemes go to: 0.315W/(m2·K)and 0.250W/(m2·K), which can meet the residential building envelope heat transmission coefficient limit value in the cold areas of China well.
