Urban areas are facing challenges like air pollution, temperature rise, lack of greenery etc, which in turn affect the productivity of city dwellers and leads to an increase in energy expenditure. By integrating more plants to urban areas as green roofs, facades and vertical walls are a solution in limited space and land availability. Giving green skin to the city buildings can lead to better macroclimatic conditions, better living environment and in long run, it can reduce global warming. Bosco vertical is an example of a green covered building situated in Milan, Italy. To adopt such a green cover, an initial investment required. The practical aspects of integrating plants to buildings required sufficient structural capacity of the building and need additional expenditure. The intensity of changes in similar dimension buildings before and after the integration of green systems is studied with the help of a theoretical example. Different systems used in green integrated buildings are intensive green roofs, extensive green roofs, green facades, and vertical green walls. For high rise buildings, the additional cost comes approximately 5% of the total project cost.
