Thermal Resistance of Insulated Precast Concrete Sandwich Panels

Abstract Many nations are already working toward full implementation of energy efficiency in buildings known as Green Building. In line with this perspective, paper aims to develop a thermally efficient precast concrete sandwich panels (PCSP) for structural applications. Therefore, an experimental investigation was carried out determine the thermal resistance proposed PCSP using Hotbox method and results were validated finite element (FEM) COMSOL Multiphysics Software. The designed staggered shear connectors avoid bridges between successive layers. spaced at 200 mm, 300 mm 400 on each layer, while control panel is direct connection. test, four (4) 500 × 150 thick subjected Test resistance. result shows that connection increases increase spacing. indicates best ( R value) 2.48 m 2 K/W. performance verified by FEA which less than 5% error coupled precise prediction surface temperature gradient. This that, conventional materials, path approach can be used building better resistant properties. Hopefully, stakeholders green industry would find alternative load bearing towards sustainable greener buildings.
