In a crowded city, any square meter of vegetation matters. For one person only 3 square meters of green roof are enough to provide their daily oxygen, the amount of carbon dioxide in the atmosphere being considerably reduced. In addition to micro particles in the air, vegetation also captures the sound waves, decreasing the number of decibels.
In summer, the vegetation installed on the roofs of tram stations reduces the effect of “heat island” and increases the cooling effect, while in winter, the green structure behaves like a “fur”, helping to increase the thermal insulation effect. In addition, the spaces that are normally unused become green oases with a special aesthetic value and with the power to improve the people mood.
