Carbon dioxide meter analyzes the effect of roof greening on air carbon dioxide
Greening is particularly important today as urbanization advances. At the same time, the greening of roofs has been gradually discovered by people. It is generally believed that roof greenery directly absorbs carbon dioxide through the photosynthesis of plants, and secondly, it can improve the thermal performance of the roof and reduce the emission of carbon dioxide so that the content of carbon dioxide in the air can be reduced. Are these theories valid in practice? This also requires more research. For the determination of carbon dioxide, a carbon dioxide meter can be used for effective analysis.
It is known that plants can absorb carbon dioxide in the air through photosynthesis and convert it into dry matter and store it in the body. However, the photo-reaction stage in plant photosynthesis must have the participation of light. In contrast, plants do not breathe all the time, decompose the organic matter in the body, release the energy needed for life activities, and release carbon dioxide. Only when the photosynthesis of plants absorbs more carbon dioxide than the respiration releases of carbon dioxide does the plant actually reduce the carbon dioxide in the air through physiological activities. At this time, plants will continue to accumulate dry matter.
If you consider the entire life cycle of a single plant, plants that have green roofs do not have a significant effect on the amount of carbon dioxide in the air. This is because the dry matter that the plant fixes carbon dioxide during the growth process will be decomposed during the aging process and after death, and then turned into carbon dioxide again into the air. Therefore, just because plants can absorb carbon dioxide through photosynthesis, it is incorrect to assert that roof greening can reduce the amount of carbon dioxide in the air. However, if we consider the propagation of plants, or artificially maintain the biomass of the vegetation roof at a more vigorous level, then the greening of the roof can always hold the amount of carbon dioxide corresponding to the amount of vegetation.
When compared with existing roofs, the energy-saving and emission-reducing effects of the roof of A. sinensis vegetation will be significantly reduced. Therefore, under actual circumstances, through the CO2 measurement instrument, it was found that the annual emission reduction achieved by saving 1 million square meters of vegetation on the vegetation roof may be only 1,000 tons of carbon dioxide or even less. To sum up, although the vegetation roof of Sinthosporium can indirectly reduce the carbon dioxide content in the air by reducing the energy consumption of buildings, the effect is not obvious.
Through the measurement and analysis of the carbon dioxide meter, it was found that the greening of the roof can reduce the carbon dioxide content of the air in many ways, but the effect is not obvious. However, this cannot completely deny the value of roof vegetation. Its more advantages need to be gradually discovered in practice and research.
