Green Roof Co2 Reduction

Over time these emission reductions add up to significant amounts.

Green roof co2 reduction.

The reduction of co 2 concentration in the region adjacent to the green roof depends on the intensity of the wind. 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. 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.

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. Reduced air pollution and greenhouse gas emissions. 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. By lowering air conditioning demand green roofs can decrease the associated air pollution and greenhouse gas ghg emissions from conventional power sources.

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. Plants breathe in the greenhouse gas like we.

Plants absorb sunlight 50 is absorbed and 30 reflected. The weaker the wind is the greater the reduction is 14. 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. 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. The weak wind slows down the mixing of co 2 generated by the convection process. Reduces the ambient temperature.
