Abstract
Natural energy sources are being ceased, due to the drastic development of various industries, along with the utilization of technology. Energy, related to the building sector has accounted for almost 23–50% of the world’s energy demand. Besides, reinforced concrete roof slabs have potential to contribute to this operational energy demand, acting as a heated body in the daytime. Therefore, our primary objective was to develop an energy-efficient slab system for low and middle-income families by adopting cost effective roof insulation. Accordingly, this study was directed in small scale physical models to investigate insulation characteristics of the EPS (Expanded Polystyrene) based concrete panels combined with NERD (National Engineering and Research Development) slab system. A parametric study was carried out using energy models, calibrated using the field results. Moreover, the thermal characteristics of this composite slab have displayed better results compared to prevalent roofing systems. The structural performance was assessed, in comparison to the conventional NERD slab system. This novel slab system performs well in tropical climatic conditions when it is installed with passive features. The overall decrement factor and the optimum insulation thickness were obtained as 0.6 and 75 mm respectively. Furthermore, the production of these insulation panels is an efficient way to dispose of non-biodegradable polystyrene waste.
