Abstract

GREEN ROOF is a roof which is mostly covered with vegetation and soil or is covered with vegetative medium. Chlorophyll creation has a positive impact on the climate of the city and can also contribute positively to providing cool air inside the buildings. This cooling of air occurs through reducing the penetration of heat through the roof and providing a stronger insulation to prevent indoor air to become warm. As a result, the indoors temperature can be easily decreased during summer and increased during winter. Reducing energy consumption is one of the major concerns for sustainability in cities. Creating roof garden is suggested as one of the ways to REDUCE ENERGY CONSUMPTION in major cities. Roof garden or GREEN ROOF-if properly designed and implemented by considering climate issues-can greatly help to REDUCE ENERGY CONSUMPTION.Changing buildings roofs to GREEN ROOFs could improve the exchange of air between areas of high building density and open spaces between them and accordingly adjust the city›s air moisture. This technology has several advantages including less wastage of heating and cooling, purification of air, reduction of noise pollution, and most importantly energy consumption efficiency–factors that can help the stabilization of city life.Due to the improvement in the social, economic and environmental conditions, the development of GREEN ROOFs have always been at the top of the agenda in advanced cities. Heat loss through the roof of the buildings is high and there is a lot of energy wastage in higher floors units. Therefore, the GREEN ROOF is a solution for this problem. GREEN ROOFs by rising roofing layers, act as a thermal insulation and help control heat exchanges between the inside and outside of the buildings.In the present research, after recognizing that benefits of GREEN ROOFs with this hypothesis that "GREEN ROOF and how design of GREEN ROOF have effective role in reduce HEAT TRANSFER" with help of analysis software called ansys, three samples of conventional roofs, GREEN ROOFs conventional and GREEN ROOFs with special detail (fiber glass layers) analyzed and HEAT TRANSFER comparative compared. Also, installed heat sensors to verify the thermal performance of GREEN ROOFs for designed GREEN ROOFs and simple ample of normal GREEN ROOF, indicate optimization of designed GREEN ROOF respect to normal GREEN ROOFs, heat performance wise. With software analysis and laboratory samples, GREEN ROOF compared to 50% less HEAT TRANSFER rather conventional roof and GREEN ROOF with fiber glass layers to 40% rather GREEN ROOF conventional optimized. Shading and evaporative cooling plants and also the role of roof layers that all perform like insulation, have effective role in reduce HEAT TRANSFER.In researched, methodology research related to the benefits of GREEN ROOF is descriptive and qualitative approach. But in sectors related to software analysis, these had quantitative approach and analytical methodology.
