Green Roof Co2 Reduction

The weak wind slows down the mixing of co 2 generated by the convection process.

Green roof co2 reduction.

By lowering air conditioning demand green roofs can decrease the associated air pollution and greenhouse gas ghg emissions from conventional power sources. With a green roof you are contributing to air purification. 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. The reduction of co 2 concentration in the region adjacent to the green roof depends on the intensity of the wind.

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

The summer savings on the top floor of the building would be in the order of 20. 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. Each time you recycle or compost materials instead of discarding them you help reduce greenhouse gas ghg emissions and protect the climate. So this helps to create a cooler and more pleasant climate.

Plants absorb sunlight 50 is absorbed and 30 reflected. The plants in a green roof filter particulate matter from the air and convert co2 into oxygen. This study also calculated the reduction on floors below the upper floor. 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.

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. 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. 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.
