Green Facades as a New Sustainable Approach Towards Climate Change

For various reasons, sustainability today is producing an important and interesting approach between architecture and the environment. This is taking place in forms and with different degrees of intensity. Within the challenges of energy crisis and climatic changes architects started to develop new approaches to address the quest of energy demands in buildings.One of these approaches is façade greening which started to take an important place in the last 10 years, it's not considered a new innovation, where applying green facade is not a new concept; however it has not been approved as an energy saving method for the built environment.Vertical greening can provide a cooling potential on the building surface, which is very important during summer periods in hot climates. The cooling effect of green facades has also an impact on the inner climate in the building by preventing warming up the façade.Within this quest, this paper is focused on the analysis of the effect of green facades systems on the building temperature and addressing different types of green facades systems and their thermal effect.
