The paper’s main goal is to analyze the efficiency of roof and wall systems based on varying insulating material layers in the tropical climatic region of Vijayawada, Andhra Pradesh, India. This research is carried out on “e-QUEST” software for energy analysis which is determined on monthly basis and the results gave evidence about energy consumption of building envelope and its operational life cycle costing. The wall and roof system have been studied for computation of the operating energy requirements and its subsequent carbon footprints which comes under concept of sustainability of building. The materials identified for insulating roof are vacuum insulated panels, wool glass, phenolic foam, expanded polystyrene, polystyrene, and for wall are cellulose, fiber glass, mineral wool, polystyrene, aero gel. Due to both have insulation of wall and roof systems the passage a source of heat minimized because of which the cooling demand is reduced on building and ultimately leads to lowering of energy consumption. Hence this study is crucial to understand the resident indoor air comfort, environmental and long-term economic benefits.
