Green Roof Co2 Reduction

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.

Green roof co2 reduction. Green roofs also indirectly reduce co2 releases from power plants and furnaces by reducing demand for heating and cooling suggesting long term economic and environmental benefits of green roofs. This study also calculated the reduction on floors below the upper floor. The plants in a green roof filter particulate matter from the air and convert co2 into oxygen. 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.

With a green roof you are contributing to air purification. Over time these emission reductions add up to significant amounts. So this helps to create a cooler and more pleasant climate. The summer savings on the top floor of the building would be in the order of 20.

Studies by environment canada have shown that the upper floor of a building with a green roof is likely to save 20 of its energy demand by reducing its need for cooling. Vegetation can also remove pollutants and ghgs from the air through dry deposition and carbon sequestration and storage respectively. Reduces the ambient temperature. Reduced air pollution and greenhouse gas emissions.

The findings add to the already known environmental benefits of green roofs including reducing carbon dioxide decreasing storm water runoff and cutting down on urban heat according to psu. Plants breathe in the greenhouse gas like we. The weaker the wind is the greater the reduction is 14. In fact ghg reductions from recycling and composting are often so considerable that they can be compared to avoided tailpipe emissions from vehicles or cars taken off.

The weak wind slows down the mixing of co 2 generated by the convection process. Each time you recycle or compost materials instead of discarding them you help reduce greenhouse gas ghg emissions and protect the climate. Green roofs can be used as a passive technique to reduce co 2 emissions from the atmosphere in urban surroundings because the green roof vegetation and soil layers can through the photosynthesis process capture co 2 from the surroundings velasco and roth 2010.
