Green Roof Co2 Absorption

Water is stored by the roof s substrate and.

Green roof co2 absorption.

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. Green roofs reduce stormwater runoff mitigate urban heat island effects absorb dust and smog sequester carbon dioxide produce oxygen create space for food production and provide natural. Green roofs play a significant role in retrofitting the low impact development lid practices in urban areas. And 3 computer simulation of.

Green roofs are sprouting up more and more on buildings. The study comprises three parts. Green roofs can reduce stormwater runoff via water wise gardening techniques. Experimental studies have shown that an extensive sedum roof can absorb approximately 1 2 kg of co 2 m 2 year in the plants themselves.

Green roofs can make a big contribution to reducing co 2 emissions. The co2 absorption rate of a plant in the daytime was much higher compared with the co2 emission rate at night providing the green roof ability to reduce the co2 concentration in the nearby region. A study presented at the green roofs for healthy cities conference in june 2004 cited by the epa found water runoff was reduced by over 75 during rainstorms. Such as the ability to absorb carbon dioxide reduce stormwater runoff limit heat absorption and provide habitats for insects birds.
