Building energy saving has been one of our greatest concerns due to the energy crisis and global warming. In this respect, building energy code is gradually getting stricker than that in any other time. As the thickness of the insulation required to satisfy the reinforced regulation is getting larger, the existing resistive insulations such as polystyrene foam board or fiberglass matt could barely be used in a single material constitution. This study presents the possibility of complex insulating wall combination using reflective insulation. Reflective insulation works when it faces air spaces and its surface has low emissivity under 0.05. In this study, the variables affecting the thermal resistance of reflective insulation were investigated. and the calculating methods for the thermal resistance of reflective air space and the solid wall structures were studied through literature survey. This study shows the possible complex insulation wall combinations suitable for the reinforced exterior wall insulating regulations. The configuration contains exterior insulation using reflective insulation in addition to the existing interior insulation.

From Jan. 1, 2020, public buildings above overall area of 1,000m2 should get the Zero Energy Building Certification. The building energy saving design code was reinforced on Sep. 1, 2018 and the building fire safety code was also reinforced on Aug. 6, 2019. This study investigated the recently reinforced building energy saving design code and building fire safety code and presented the required thickness of various insulations to meet the reinforced building insulation and fire safety code. The result of this paper also presented non-combustible insulations which can be used as exterior insulations for the buildings above 3 stories. Non-combustible Glass wool 48K, Mineral wool, Phenol Foam, Low-Emissivity Hybrid Insulation and Vacuum Insulation Panel for the exterior wall of apartment buildings in central 1 region can be used as thick as 220mm, 255mm, 130mm, 100mm and 20mm, respectively.
