Simple Environmental Treatments for Heat Transfer of Building Ceilings

摘要

The increase of global warming in the world and in Iraq especially because of various environmental phenomena, as a result of the increasing demand for energy, there was a need to find the means to save energy and achieve sustainability while ensuring the needs of the individual. In this research, the thermal behavior of a building in a pre-built Baghdad area was examined, specifically in a room on the third floor to ensure that the sun is not blocked by surrounding buildings. Two cases were selected to cover the roof of the building, the first is the use of the 50 mm thick American thistle with spraying and the second is the water spray with the same amount of water used to irrigation the thistle. All aspects of the study were designed to ensure that only temperature changes were focused on the ceiling. The thermal insulation of the walls of the room was also used and also provided with a 1 to n air conditioner to provide standard thermal conditions. The temperature of the external and internal surfaces for the roof of the concrete building for the three cases has been measured (without cover, covered with American thistle, covered with water) from 6 am to 6 pm during the months of high temperature in June, July, August and September, with a reading rate of one every two hours. The study showed that the use of green areas will provide electricity equivalent to 54% of the ordinary ceiling without cover, while the water areas will save 41% for the same conditions, that the green areas have shown a higher efficiency to provide energy with better available technologies thus achieving the basic aspects of sustainable environment.
