Abstract:
Steady-state heat transfer of built-in composite insulation walls close to column had been investigated in this paper by using finite element analysis (FEA). Firstly, the thicknesses of the wall and the thermal insulation were determined according to energy saving requirement of 75%. The heat transfer of the wall with the commonly used details was studied and it was found although adding local insulation on the outside of the column can improve the heat flow concentration, there is still a thermal bridge at the junction of the wall and the column. Then the influence zone of the thermal bridge was investigated and a construction measure of extending the local insulation width was proposed based on the analysis results. Lastly, the partial thermal insulation extended widths for different column sections and thermal insulation were suggested to break thermal bridge completely, which can meet the energy saving requirement of Beijing government. © Published under licence by IOP Publishing Ltd.
