Green building with environment-friendly and energy-saving functions

The invention relates to the field of green buildings, in particular to a green building with environment-friendly and energy-saving functions. According to the technical scheme, the wall absorbs solar heat and conducts the solar heat into a room, the refrigeration burden of an air conditioning unit is greatly increased, and energy consumption is further increased. According to the technical scheme, the green building with the environment-friendly and energy-saving functions comprises a building wall, an irrigation assembly and the like; an irrigation assembly is installed on the right portion of the upper side of the building wall. During use, rainwater is automatically collected, heat insulation and heat absorption treatment is conducted on the wall through the collected rainwater, so that heat flowing into a room through the wall is reduced, the refrigeration burden of an air conditioning unit is reduced, the energy-saving effect is achieved, meanwhile, plants are irrigated through the collected rainwater,
