Enhancing Energy Efficiency in Hot Climates via Wall and Roof Insulation Techniques

In last two decades, energy consumption worldwide has increased by more than 30%. The limited thermal conductivity of thermal insulation materials is currently receiving significant attention in hot-weather countries where temperatures reach high levels. This leads to a significant decrease in the demand for energy in HVAC systems and reduces the negative effects on the environment. The purpose of current study is to define the optimum construction techniques for buildings to enable energy savings while occupying minimal space. This research dedicated on the role of wall and roof materials in the energy efficiency of a building by exploring different options, including variations in materials and construction methods. The study employed mathematical calculations to determine the U-value of wall and roof insulating materials. The results indicated that cavity walls with insulation material and cavity roofs with an air gap and insulation material are optimal solutions for improving energy efficiency in buildings. This study recommended considering long-term energy savings to substantiate the effectiveness of these materials in conserving energy for buildings.
