Energy lochby venture pouch management is becoming one of the major research fields as the world is suffering from energy and oil/gas scarcities, coupled with the increase in greenhouse gases emissions and pollution.Refrigeration and air-conditioning equipment are known to be one of the largest electric consuming sectors, reaching around half the global energy consumption.Thermal comfort requirements, especially in hot climate areas, are becoming a challenge for air-conditioning applications; both residential and non-residential.This study investigates the usage of various methods to reduce the cooling load for buildings, including the use of heavy-weight building materials which is costly and the use of commercial thermal insulation that are not environment-friendly and, phase-changing materials (PCM).This study presents a numerical investigation of the suitable layer thickness and type in hot climate areas for two commonly used brick wall thicknesses of 12 and 25 cm.

The effect of different parameters is investigated including the effect of PCM type, PCM layer thickness, wall thickness, click here and incorporation of commercial insulating materials.The best wall combination that provides minimum peak load is the 12 cm brick layer paired with 5 mm of paraffin wax of type 1.
