Green Roof Co2 Reduction

The plants in a green roof filter particulate matter from the air and convert co2 into oxygen.

Green roof co2 reduction.

Reduces the ambient temperature. Over time these emission reductions add up to significant amounts. Vegetation can also remove pollutants and ghgs from the air through dry deposition and carbon sequestration and storage respectively. Reduced air pollution and greenhouse gas emissions.

The weaker the wind is the greater the reduction is 14. 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. Plants absorb sunlight 50 is absorbed and 30 reflected. By lowering air conditioning demand green roofs can decrease the associated air pollution and greenhouse gas ghg emissions from conventional power sources.

The weak wind slows down the mixing of co 2 generated by the convection process. 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. With a green roof you are contributing to air purification. Each time you recycle or compost materials instead of discarding them you help reduce greenhouse gas ghg emissions and protect the climate.

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. 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. 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. So this helps to create a cooler and more pleasant 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. This study also calculated the reduction on floors below the upper floor. Plants breathe in the greenhouse gas like we.
