Abstract

The purpose of this study is to compare the energy performance of the existing case using a conventional rectangular pipe frame and alternatives using double and single truss-shaped insulation frames and insulation pads to reduce linear and point thermal bridges in a stone-finished exterior insulation system. Annual heating and cooling energy use was estimated by performing a dynamic building energy simulation. In the building energy simulation, the thermal bridging effect was reflected by the linear and point thermal transmittance obtained from the 3D steady-state heat transfer simulation. Annual heating and cooling energy cost was estimated together. The results showed that the annual energy use of alt D and alt S with insulation frame decreased by 15.4% and 16.6%, the annual energy cost decreased by 14.6% and 15.7%, respectively. The annual energy use of alt D-P and alt S-P with insulation frame and pad decreased by 15.5% and 16.8%, the annual energy cost decreased by 14.7% and 16.0%, respectively.
