Zero carbon buildings refer to buildings with zero carbon emissions, which can operate independently of the power grid, and can operate on solar energy or wind energy. This kind of building does not consume coal, oil, electricity and other energy, and the energy consumption of the whole year is provided by the renewable energy generated by the site. The so-called zero carbon city means that cities do not have any negative impact on climate change, or to minimize greenhouse gas emissions. Zero carbon building is an important aspect of zero carbon city. It refers to the use of comprehensive building design methods, not using conventional polluting energy (zero energy) and green area (zero ground) buildings, in order to maximize the realization of zero carbon city.
Zero carbon building not only uses all kinds of means to reduce its own pollution, but also uses waste reasonably, uses environmental protection and clean energy to reduce carbon dioxide emissions, and finally achieves the ideal state of "zero waste water, zero energy consumption, zero waste".
The energy consumption of zero carbon buildings is roughly equal to the energy generated by itself, so as to achieve zero emissions. The main principle of zero carbon building is: to achieve "zero energy consumption" by using the biomass energy produced by the fermentation of solar energy, wind energy and organic waste as the core energy; to achieve "zero waste water" by flushing toilets or irrigating plants with rainwater collected from the roof, so as to reduce the demand for tap water; to use organic waste for power generation, and to make inorganic waste into furniture or building materials, so as to achieve "zero energy consumption" "Zero waste".
