The reduction of co 2 concentration in the region adjacent to the green roof depends on the intensity of the wind.
Green roof co2 reduction.
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.
Each time you recycle or compost materials instead of discarding them you help reduce greenhouse gas ghg emissions and protect the climate.
By lowering air conditioning demand green roofs can decrease the associated air pollution and greenhouse gas ghg emissions from conventional power sources.
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 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.
This study also calculated the reduction on floors below the upper floor.
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.
The summer savings on the top floor of the building would be in the order of 20.
Vegetation can also remove pollutants and ghgs from the air through dry deposition and carbon sequestration and storage respectively.
Plants absorb sunlight 50 is absorbed and 30 reflected.
The weak wind slows down the mixing of co 2 generated by the convection process.
Over time these emission reductions add up to significant amounts.
Plants breathe in the greenhouse gas like we.
The plants in a green roof filter particulate matter from the air and convert co2 into oxygen.
With a green roof you are contributing to air purification.
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.
Reduces the ambient temperature.
Reduced air pollution and greenhouse gas emissions.
