Abstract

Thermal efficiency, often known as U-value, is an important statistic that is used to estimate the amount of heat that is lost via the various components of a building as a result of heat transfer. The ability to estimate it is provided by the thermal characteristics of the building's components. By increasing the thermal properties of composite walls, it is conceivable to reach high energy and environmental performance objectives for buildings, such as essentially zero-energy structures. This would be possible if it were possible to achieve these goals. Despite the benefits of this form of construction, thermal bridges may still be present in wall elements. This is because structural materials have a high thermal conductivity, which makes them susceptible to heat transfer. The purpose of this study is to evaluate how the functionality of composite walls is affected by the presence of layers of thermal insulation. In order to accomplish this goal, several different types of composite walls are assessed in each of the four main temperature zones. The only two pieces of information needed to calculate thermal transmittance using this method are the temperature of the surrounding air and the properties of the wall material. The newly established method known as MCDM generates three distinct groups of results, which are as follows: (a) the heat burden of the composite material; (b) the overall cost of the utilized wall composite materials; and (c) the ranking outcomes. An comprehensive statistical research reveals thatthe climate in this method has a direct influence on the amount of heat that a structure must bear as well as the effectiveness of various types of insulating materials
