In order to meet the challenges of global climate change, shortage of resources and energy, and deterioration of ecological environment, human beings are following the concept of carbon cycle, developing circular economy, building low-carbon ecological cities and popularizing low-carbon living buildings.

2012165438+122 October, at the third China Housing New Trend Summit Forum held in Beijing, Li Congxiao, director of the Green Building Research Center of China Urban Science Research Association, pointed out that it is the general trend to develop green buildings in China, and one-star buildings are expected to become mandatory green buildings in the future.

20 13 Shenzhen is making every effort to build a green building capital. All kinds of energy-saving and low-carbon green buildings have become the main force of construction, from the roof greening of mountain gardens to the solar power generation in the Garden Expo Park, and then to the low-rent housing project Longyueju, which integrates low-carbon technologies such as constructed wetlands, water recycling and solar energy. All these profoundly show that Shenzhen has taken a bold step towards the "green revolution".

Design concept of green building

1, saving energy

Make full use of solar energy, adopt energy-saving building envelope and heating and air conditioning to reduce the use of heating and air conditioning. According to the principle of natural ventilation, an air cooling system is set up to make the building effectively use the dominant wind direction in summer. The building adopts plane form and general layout adapted to local climate conditions.

Step 2 save resources

In the design, construction and selection of building materials, the rational utilization and disposal of resources are considered. We should reduce the use of resources and try to make them renewable. Save water resources, including greening.

Step 3 return to nature

The exterior of green building should emphasize the integration, harmony and dynamic and static complementarity with the surrounding environment, so as to protect the natural ecological environment. Comfortable and healthy living environment: building materials and decoration materials harmful to human body are not used inside the building. The indoor air is fresh and the temperature and humidity are suitable, which makes residents feel good and healthy.
