Effect of Using Local Insulation Materials on the Indoor Temperature of Residential Buildings at Iraq
In this research, a thermal insulation between the two layers of a wall has been used for the residence buildings to reduce the heat transmitted across the walls and thus reducing the power consumption for cooling load.

| description | In this research, a thermal insulation between the two layers of a wall has been used for the residence buildings to reduce the heat transmitted across the walls and thus reducing the power consumption for cooling load. A MATLAB program was used to obtain the thermal response for various types of walls from the energy sources (solar radiation and ambient temperature) in summer season in Baghdad, Iraq. Local materials used in this study as thermal insulators between the two layers of walls are: local cane mat, wood sawdust and cork grains. Modeling tests were carried out on June, July and August via using Matlab program. The simulation results obtained have been compared for five different types of walls are: usual wall, thick wall, wall containing local cane mat, wall containing wood sawdust and wall containing cork grains, which helps in finding the heat flow across the wall where boundary conditions varied according to solar radiation and environment thermal load. The results showed that using the walls containing of local cane mat, wood sawdust and cork grains can reduce the heat gain by 50%, 44% and 40% respectively, compared with usual wall and thus reduce the power consumption. |
