Investigating the Thermal and Energy Performance of Advanced Glazing Systems in the Context of Hail City, KSA

Most new housing designs in Saudi Arabia are created to meet the client’s needs with minimal regard for environmental or energy-related considerations, resulting in buildings’ poor thermal performance and a growing reliance on artificial means. Polycarbonate windows have recently acquired popularity. Yet, there is a rising interest in combining polycarbonate windows with nanomaterials to reduce energy consumption, especially during the summer months when air conditioning use is at its peak. To improve building insulation, this research concentrated on the use of polycarbonate windows with nanogel, which has a low U-value. This study utilized polycarbonate windows with nanogel (two layers of polycarbonate panes filled with nanogel) in Hail City, Saudi Arabia, using DesignBuilder simulation software, resulting in a 14.3% reduction in annual energy consumption. The low U-value of nanogel compared to argon or air may be the cause of these savings, which are roughly double those gained by using double-paned polycarbonate windows. The incorporated nanogel layer between two layers of argon and two layers of polycarbonate panes decreased annual energy consumption by 29% compared to utilizing only one polycarbonate layer. Moreover, compared to a single 3 mm polycarbonate pane, the nanogel layer placed between two layers of argon and two layers of single polycarbonate panes demonstrated the lowest level of CO2 emissions, with an improvement of around 22.23%. This study reveals a method for insulating buildings that cuts energy use and CO2 emissions. This study’s conclusion supports the notion that sustainable design is the future. Sustainable construction can dramatically reduce building cooling costs and thermal loads.
