Green Roof Co2

Greening conventional roofs requires special materials which come at a carbon cost.

Green roof co2.

Green roofs are considered effective in the reduction of atmospheric co2 because of their ability to reduce energy consumption of buildings and sequester carbon in plants and substrates. It takes seven years for the roof to offset the carbon used for its building materials and become truly carbon. Plants breathe in the greenhouse gas like we. With a green roof you are contributing to air purification.

Green roofs can be used as a passive technique to reduce co 2emissions from the atmosphere in urban surroundings because the green roof vegetation and soil layers can through the photosynthesis process capture co2 from the surroundings velasco and roth 2010. Plants absorb sunlight 50 is absorbed and 30 reflected. While many researchers understood that green roofs were multi functional because of their ability to reduce heating and air conditioning costs detain stormwater and absorb carbon dioxide it. Like any forested or vegetation covered area a patch of green on top of a roof should theoretically lower levels of carbon dioxide in the air as well.
