The so-called “green building” of “green” does not refer to the general sense of three-dimensional green, green roof building reduction, but rather represents a concept or symbol that the building is environmentally sound, can make full use of the environment’s natural resources, and does not damage the environment in the basic It is a kind of building built under the condition of ecological balance, and can also be called sustainable development building, ecological building, back to nature building, energy saving and environmental protection building, etc. The green building evaluation system is divided into basic level, one star, two stars, and three stars. The green building evaluation system is divided into basic, 1-star, 2-star and 3-star in the new national standard.
1. Permeable floor design
Water permeable flooring as a new environmentally friendly and ecological road material. Water permeable flooring can make rainwater quickly infiltrate the surface, effectively replenish groundwater, alleviate the urban heat island effect, to protect the city’s natural water system from destruction, has a strong environmental value. At the same time, it solves the problem of common road surface that is easy to accumulate water, improves the safety and comfort of walking, and is also of great significance for improving the living environment.
2. CFD environmental optimization design
Optimize the indoor and outdoor environments of buildings with CFD digital simulation methods.
3. Energy-efficient building design
Vigorously advocating energy conservation and emission reduction, the urgent need for building units to solve the problem is to be reasonably energy efficient in the design of civil buildings. This can not only effectively realize the construction of an economical society, but also is a major driving force of urbanization construction. In the civil building energy-saving design, the main attention is paid to two aspects of the design: the heating system, cooling system and housing construction of the building envelope structure, so the civil building energy-saving design needs to focus on these two centers, while reducing energy consumption, but also take into account the construction quality of housing and to ensure the comfort of living.
4. Solar hot water systems
Solar hot water system is the use of solar collectors to collect heat from the sun, under the sun’s rays so that the sun’s light energy is fully converted into heat, through the control system automatically control the circulation pump or solenoid valve and other functional components of the system to collect the heat transmitted to the large water storage tank, in matching the equivalent amount of electricity, gas, fuel and other energy sources, the water in the water storage tank heating and become more stable quantitative energy equipment.
5. Green Lighting System
Green lighting contains four indispensable indexes: high efficiency and energy saving, environmental protection, safety and comfort. Energy efficient means to consume less power to obtain sufficient lighting, thus significantly reducing the emission of air pollutants in power plants, to achieve the purpose of environmental protection. Safety and comfort means that the lighting is clear, soft and does not produce harmful light such as ultraviolet rays, glare, etc., and does not produce light pollution.
6. Rainwater reuse systems
Rainwater reuse system, that is, after the collection of rainwater, according to the different needs of the collected rainwater treatment to meet the design standards for the use of the system. Most of the current by the abandoned filtration system, water storage system, purification system composition. Scientific, reasonable, efficient use of rainwater resources, not only can alleviate urban water shortage, but also can nurture and protect water resources, control urban soil erosion, reduce waterlogging, control the funnel effect of urban groundwater over extraction and sedimentation, reduce water pollution and improve the urban ecological environment.
7. Water-saving irrigation
Water-saving irrigation means achieving better production and economic efficiency with less irrigation water. The basic requirement of water-efficient irrigation is to take the most effective technical measures to create the best production and economic benefits from the limited amount of irrigation water.
8. Integration of civil construction and decoration
Refinished design, a variety of renovation plans.
9. Efficient heating and ventilation equipment system
Use high efficiency HVAC equipment, such as VRVs.
Access control security systems, communication network systems, etc.
