With the continuous increase of its construction, the artificial environment network has been gradually built and improved in large cities, even connecting the whole city, bringing almost all the life tracks of people from living to working into the artificial environment. According to statistics, people in cities spend an average of 80% - 90% of their day in buildings. The relationship between buildings and human beings, especially the impact of the health of the indoor environment of buildings on people, is not only the need for sustainable development of human health and survival, but also one of the preconditions for sustainable construction of artificial environment.
Public buildings Only 15% of the total building area, but energy consumption accounts for 28.3% of the total building energy consumption
The construction proportion of large-scale public buildings in urban public buildings is increasing day by day. Because of its large building block, large number of users, centralized use space, and complete use of centralized central air-conditioning system, in some types of large-scale public buildings, especially office buildings, the opportunities for people to contact with nature are greatly reduced, It makes the user's demand for contact with the natural environment more urgent.
In addition, from the energy consumption statistics of different building types, the National Development and Reform Commission pointed out in the 2007 China Sustainable Energy Research that, "Public buildings account for only 15% of the total building area, but energy consumption accounts for 28.3% of the total building energy consumption. Among public buildings, large public buildings account for only 8.3% of the area, but energy consumption accounts for 38% of public buildings. In China, large public buildings account for less than 4% of the total urban building area, but energy consumption accounts for more than 20% of the total urban building energy consumption, which is the density of building energy consumption Degree domain.
Active building refers to a kind of building that can realize the comprehensive balance of health, comfort, resource conservation and environmental protection through the perceptible and adjustable ability of the building during the whole life cycle of design, construction, operation and maintenance of the building, and promote the physical and mental pleasure of users.
Active building is a new modern sustainable building concept that tells people how to deal with the relationship between health and comfort, resource conservation and environmental protection.
The active architectural design strategy emphasizes that the building itself should have strong climate adaptability and self adjustment ability, and create an indoor and outdoor environment conducive to people's physical and mental health and harmonious coexistence with the environment.
The design of active buildings focuses on the scheme decision-making and design stages, focusing on the overall consideration of the whole life cycle of the building in the design stage. When designing, architects should pay attention to the control of climate adaptability, such as layout, orientation, use of the surrounding environment, as well as the use efficiency of building space, space form, and functional layout, The material structure adopted by the enclosure system and the passive technical strategy for the use of natural resources such as natural light, wind and water can avoid many possible energy consumption factors, so the prototype of the building basically determines the degree of "initiative" and "sustainability" of the building. The active architectural design concept introduced from the building prototype not only emphasizes the attention to the healthy and comfortable use environment of users, but also affects the energy consumption during the operation of the building.
