Greenroofs give an extra isolation to the roof. Due this there is less heath wasted though the roof in the winter. And in the summer it cools your roof. Where a normal roof gets up to 70°C, the maximum of a greenroof is 35°C. Like this is works like an air-conditioning.
Plants purify the air by absorbing CO2 and fine dust. This gives us a cleaner environment.
In sommige gemeentes krijg je subsidies per m² groen dak dat je aanlegt. Het verschilt ook tussen verschillende gemeentes, dus je kan best eens bij je eigen gemeente horen.
Greenroofs offers hiding places for insects, bees and bird. Like this we aren't only bringing plants into the city but also animals.
Extends lifespan roof
Greenroofs protect the roof covers against weather influences like rain and UV-radiation. Your roof cover can last up to 5 times longer with a greenroof. Like this the investment pays itself back.
Urban Heat Island effect
The 'Urban Heat Island' effect is the simple fact that the average temprature in the city is up to 5°C higher than in the countryside. With greenroofs we can lower this temprature.
When it rains, the sewerage can get saturated. The water comes than u in the streets. Greenroofs hold a part of the rainwater in his drainage system as waterbuffer. Like this there is less water going into the sewerage.
When you combine a greenroof with solar panels you can get a higher profit. This comes from the simple reason of cooling. A normal roof become's 70°C in the sun, a greenroof only 35°C. The solarpanel has a higher output when it's cooler. Measurements has prove that a solarpanel on a greenroof can get op to 15% more profit.
