Abstract
This study aims is to compare the energy performance and economic feasibility of outer wall insulation systems using conventional rectangular pipe frames as the base case with double and single truss-shaped insulation frames intended to reduce the thermal bridging effect of alt 1 and alt 2. Annual heating and cooling energy use were estimated by performing a dynamic building energy simulation. The thermal bridging effect was modeled by applying the linear thermal transmittance obtained from the three-dimensional steady-state heat transfer simulation to the building energy simulation. The annual energy cost, construction cost, and life cycle cost for 30 years were estimated together. The results indicated that the annual energy use of alt 1 and alt 2 decreased by 12.5% and 13.9%, the annual energy cost decreased by 11.8% and 13.2%, the construction cost decreased by 1.4% and 6.8% and the life cycle cost of alt 1 and alt 2 decreased by 2.6% and 7.5% respectively. © 2022 Architectural Institute of Korea.
