Abstract:In today's global conditions, due to decreasing fossil-based energy sources and population growth, increase in multi-storey buildings caused environmental problems. The %50 of energy sources of the world is being used by the buildings. This fact emphasizes the concept of "ecological-energy efficient building design" which is used by architects and engineers when searching the solutions using the passive systems to design the building that meets the expected energy saving platform provided by natural comfort zone by lowering the mechanical loads as much as possible. By the way the roof of a building is a component of the construction that effects the performance of the building and the green roof application is a part of this platform. The aim of this study is to analyse the heating and cooling effect of the planting on to the roofs of office buildings.For this analysis, Design Builder building energy simulation program is selected which Works with Energy Plus simulation engine.This study will be implemented on different size of office buildings in two different climate conditions as hot and cold regions. So this study allows to evaluate and benchmarking the pros and cons of the green roof applications in different climate conditions at different size of office buildings. To evaluate the efficiency of the described green roof systems simulations were also done with diffent size plant leaves and different thicknesses of the planting layers. The sparse green roof application has been defined and simulated according to those climate conditions on alternative office buildings which are eligible of TS825 constructions components. To evaluate the efficiency of the described green roof systems, simulations were also done with diffent size of plant leaves and different thicknesses of the planting layers. The energy performance of the green roof systems on buildings is %4.64 in hot climate regions and it is %3.01 in cold climate regions, which shows that green roof systems performs better in hot climate regions. Also, that shows the green roof energy performance is directproportion with the roof surface area and size of the plant leaves and it is inverse-proportion with the thickness of the green roof planting layer.
