Abstract

This research paper investigates the role of enclosing structures, specifically walls, in reducing thermal loads on buildings situated in dry-hot climates. Such climates, characterized by intense solar radiation and significant temperature fluctuations, pose unique challenges for maintaining indoor thermal comfort and minimizing energy consumption. The study evaluates the thermal performance of various wall types, including double-wall construction, insulated cavity walls, Trombe walls, ventilated facades, and Structural Insulated Panels (SIPs). Through a combination of computational simulations and experimental validation, the effectiveness of these wall systems in mitigating heat gain and reducing cooling loads is assessed.

The findings reveal that Structural Insulated Panels (SIPs) and insulated cavity walls offer the highest levels of thermal insulation, leading to significant reductions in peak indoor temperatures and cooling energy demand. Ventilated facades also demonstrate strong performance, particularly in reducing heat gain through natural ventilation. Trombe walls, with their high thermal mass, are effective in stabilizing indoor temperatures over a 24-hour cycle, offering a balanced approach to managing daytime heat and nighttime cooling needs.

 The study concludes that the selection of appropriate wall systems is crucial for enhancing energy efficiency in buildings located in dry-hot climates. While SIPs and ventilated facades provide superior thermal performance, considerations such as cost, material availability, and environmental impact should also guide the choice of construction methods. The results underscore the importance of integrating advanced wall technologies with sustainable building practices to reduce thermal loads and promote energy-efficient design in arid regions.
