Green Roof Co2 Absorption

For the initial searching of scopus and web of science wos the criteria used was ts green roof carbon sequestration or green roof co2 sequestration or green roof for air pollutant removal or green roof as pollution abatement or roof vegetation for carbon emission reduction or green roof environmental benefits with timespan 2000 march.

Green roof co2 absorption.

1 field measurement of the difference of co 2 concentration at a location in the middle of the plants in a small plot of green roof and one in the surrounding area 2 experiments to measure the plant s co 2 absorption velocity and emission rate using a sealed glass chamber. Green roofs play a significant role in retrofitting the low impact development lid practices in urban areas. By also accounting for absorption in the roots and growing medium the total absorption is assumed to be many times greater. Green roofs can make a big contribution to reducing co 2 emissions.

Water is stored by the roof s substrate and. 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. 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. And 3 computer simulation of.

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. Of these topics green roof stormwater runoff quality is the second most highly investigated 62 papers 16. The study comprises three parts. In 2010 a review of green roof runoff water quantity and.

Green roofs are sprouting up more and more on buildings. Air pollution is a relative new topic area 15 papers 4 which includes findings on carbon dioxide co 2 sequestration. Green roofs offset global warming study finds. Green roofs can reduce stormwater runoff via water wise gardening techniques.

Green roofs not only help reduce the urban heat island effect by covering conventional dark roofing surfaces with vegetation which absorbs less heat but they also use solar radiation to evaporate water from the growing media and transpire the absorption of water through a plants roots and release of it through its leaves as a vapor moisture.
