Comparison of Thermal Performance of Newly Produced Lightweight Wall and Roof Elements for Energy-efficient Buildings

Abstract

T he building sector is responsible for the enormous amount of total energy consumption in the World. Most of this energy is used for the provision of heating and cooling applications. The main objective of a cooling or heating system is to maintain the thermal comfort conditions to the occupants of the building that are required for indoor products and processes. The heat ratio that must be removed from a room to maintain a stable temperature at the comfort level is defined as a cooling load [1]. The heat gain through the building envelope, which includes roofs and walls in most buildings, constitutes a significant partition of the overall cooling load of space due to its large area [2]. If the structures having appropriate thermal properties are selected, also accurate cooling load calculation is performed, and then suitable HVAC system components can be selected. Therefore, estimation of the cooling load through the building envelope is an essential task in the selection of proper components of an HVAC system that influences the building's performance. However, an accurate calculation of the cooling load is quite complicated
