Description

Rainwater collection and recycling system for green building

Technical Field

The invention relates to the technical field of green buildings, in particular to a rainwater collecting and recycling system for a green building.

Background

The green building refers to a building which can save resources to the maximum extent within the whole life cycle of the building, comprises the functions of saving energy, land, water, materials and the like, protects the environment, reduces pollution, provides healthy, comfortable and efficient use space for people, and is harmonious with the nature. The green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization, is benefit sharing between people and nature, the present and the future, and is a construction means of sustainable development.

The green building evaluation system has seven indexes which are respectively as follows: land and outdoor environment saving, energy and energy environment saving, water and water resource utilization, material and material resource utilization, indoor environment quality, construction management and operation management; the indoor layout of the green building is very reasonable, the use of synthetic materials is reduced as much as possible, the sunlight is fully utilized, the energy is saved, and a feeling close to the nature is created for residents. The method aims at the coordinated development of people, buildings and natural environment, creates a good and healthy living environment by using natural conditions and artificial means, controls and reduces the use and damage of the natural environment as much as possible, and fully embodies the balance between asking for and returning to the nature.

The green building emphasizes the indoor environment because the main idea of the air conditioning industry is to strive for a balanced relationship between the internal and external environments, and to present different demands to the internal environment, i.e. to health, comfort and production efficiency of building users.

The living environment created by the green building comprises both artificial environment and natural environment. When the green environment is planned, not only the creation of landscape but also the integration of environment and ecology are emphasized to realize the integral greening. Namely, continuation and naturalization are considered from the overall viewpoint. Sustainable applications, in addition to the building itself, include the desired surrounding natural environment, efficient (ecological) utilization of domestic water, wastewater treatment and reduction, and local climatic conditions.

The green building needs to consider how to cooperate with the climate characteristics, economic conditions and cultural tradition concepts of the location, so that the green building becomes an inseparable integral part of the surrounding community. The green building as a secondary system depends on the natural environment in a certain geographical range, and the green real estate can not separate from the geographical property of the biological environment and independently exist. The realization of green buildings is related to the unique climate conditions, natural resources, existing human buildings, social level and cultural environment of each region.
