Not only about aesthetics
The roof covered with a layer of real vegetation
A green roof also brings many other benefits next to the aesthetic one. A two-centimeter layer of greenery is able to retain about 50-60% of rainwater. The roof of the Ovoville house with an area of 35m 2 produces oxygen for 35 people per year. Moreover, it can absorb as much as 10-20% of dust and gases from the air. It is also extremely effective in reducing noise through reflection and partial absorption of sounds, at around 20-30dB.
