Recently, concerns about conserving proper size of urban green spaces and accessibility are increasing, regarding it as
a solution to diverse urban environmental problems including pollution, ecosystem deterioration, urban climate change.
Artificial ground greening such as green roofs is regarded as the only alternative that can conserve green spaces which
are impossible to be secured on the ground. However, green roofs are not popularized yet and levels are very low in
provincial cities despite of related technology development and support systems of related agencies. Based on the
background, this study tries to present a theoretical basis of methods for green roofs, conducting green roof simulations
Finally, it aims to offer base data which help establish policy direction for activation of green roof technology. As a
result of a simulation for verifying temperature reduction effect, it was possible to affirm effect of a plot that green
roofs applied. Especially, it was revealed that a green roof method using ground covers such as mixed planting was the
most effective way to reduce temperature. Based on precise analysis of the users, actual study for activation of green
roofs should be developed in the future, by presenting a standard model for experiments and obtaining information about
examples of green roofs on private houses.
