Generally, the greening of building

Generally, the greening of buildings can be divided into three types: roof greening, vertical greening of external walls and indoor greening. Roof greening can also be widely understood as greening on the top of various buildings and structures, as well as on the roof, terrace or balcony. It is to use limited space to increase urban green, improve urban ecological environment, and provide people with beautiful environmental landscape and activity space. Vertical greening has the ecological functions and effects of increasing urban greening rate, improving urban environment microclimate, purifying air, reducing noise, reducing light pollution, heat preservation and insulation effect on buildings, and protection of building surface. For example, placing green plants on the balcony in summer can block the sunlight to a certain extent, so as to reduce the indoor temperature, reduce the utilization rate of indoor air conditioning, reduce the indoor air pollution, and promote the building to achieve the purpose of green energy saving. Indoor greening is mainly to provide people with ornamental value and purify indoor air to ensure the quality of people's living environment.
