The embodiment of "sustainable development" in architectural design

1 the proposal of the goal of "sustainable development" development is the eternal theme pursued by human society. Human history is the history of interaction, coevolution and coordinated development between human society and nature. In the process of social progress, human beings constantly summarize positive and negative experience, and constantly choose and revise their own development mode while adhering to the overall goal unchanged

Since the 1990s, the concept of sustainable development and rational thinking have begun to spread all over the world. As a new development model and strategy, the concept of "sustainable development" has been widely recognized by the world and has become a global proposition. In the new era, architects are required to explore and establish a sustainable architectural concept and design under its guidance. The characteristics of sustainable development of architecture are reflected in the coordination between architecture and environment, focusing on the long-term consideration of meeting the needs of contemporary people and benefiting future generations. Such as energy saving, water saving, material saving, noise reduction, waste pollution reduction, ecological environment protection, and the realization of coordinated and sustainable development between architecture and environment. At the same time, architectural design should also pay attention to the long-term characteristics of building use. In the service cycle, the building function should have its variability and adaptability to the future. 2. The embodiment of "sustainable development" in the internal function design. Architecture is a living and working space created by people. Its function is always changing with the progress of technology and the passage of time. The embodiment of "sustainable development" in the internal function is mainly reflected in the variability of functions at any time. "Marseille apartment", a century old building, is still full of vitality, attracting architects and visitors from all over the world, mainly because of its functional diversity and variability. p>

the creative transformation of buildings in different periods of society reveals that the development of buildings is a dynamic process involving time factors. From the perspective of some buildings at present, the aging of functions is much faster than that of physical materials, which is a huge loss to the society. Therefore, the internal function design of the building should be a dynamic design process of sustainable development, which makes it adaptive for a long time through the variability of the building. We should adapt the developing functional requirements with developable buildings and give full play to the service life of solid materials. In the design, we should pay attention to the following aspects:

(1) emphasize the awareness of overall design, that is, the design idea of emphasizing the overall situation and ignoring details. The uncertainty of the future makes it difficult for us to grasp all aspects of its development. Careful design often brings tomorrow's limitations. Therefore, the variability design should be predictive and grasp the overall design. Some design companies in the United States carry out expansion services, that is, to provide owners with the whole process of design. It is necessary to provide the owner with a series of designs rather than just a plan

(2) in terms of structure, new technologies are adopted, such as long-span prestressed composite floor slab, beamless floor slab, etc., in order to support the maximum space with less load-bearing system and provide a prerequisite for its variability. For example, for the new Kobe apartment built in Japan in 1997, in terms of structure, the trial production framework in 2012 used the reverse beam method and raised floor, and there was no beam exposed at the ceiling, which was convenient for the movement of the partition wall. The designer listed up to 31 partition wall layout schemes for residents to choose, which fully reflected its variable design idea. At the same time, the overhead floor facilitates the equipment piping, and can also be used for storage under the floor and install heaters according to Japanese customs

(3) the building shape should be as simple as possible, and the location of doors and windows should meet the conditions of various indoor layouts as far as possible, creating conditions for internal improvement

different users have different forms and positions of room separation, and the number of rooms separated is also different, so the position of doors and windows of the outer wall should meet the lighting and ventilation requirements of different rooms and meet the indoor hygiene requirements

(4) the immutable parts such as pipe wells, stairs and toilets can be arranged as a unit in order to increase the area and flexibility of the variable parts and adapt to the development of buildings. Some foreign "box" buildings are the embodiment of this idea. 3. The embodiment of "sustainable development" in the coordination of architecture and environment at present, the problem faced by the construction industry is the contradiction between sustainable development and "destructive construction". The unlimited expansion of building scale is accompanied by the deterioration of the natural environment, which poses a serious threat to human survival and development. The United Nations Declaration on the human environment and the "action plan" call on all countries in the world to pay close attention to the serious impact of human activities on the environment, Governments are urged to take measures to prevent environmental pollution and ecological damage. Then, how should the building itself coordinate with the environment to achieve the goal of sustainable development, which requires the building itself to adapt to the local ecology without destroying the local ecology. The caves on the Loess Plateau are dug for living. The temperature is moderate, warm in winter and cool in summer, which is a perfect combination with nature. Restricted by various conditions, traditional folk houses can still have a variety of creativity, so as to avoid the wind, face the sun, save energy, and create flexible and free space according to local conditions and materials. Moreover, modern society has high technology and high intelligence, so we should use advanced means to create a pleasant ecological environment, so that human beings can live in harmony with the natural environment, and maintain its ability of continuous development and sustainable utilization. Several aspects that should be paid attention to in the design:

(1) pay attention to building energy conservation. Promote the use of thermal energy-saving materials of high-efficiency Jue Jinan gold testing 600 ton horizontal tensile testing machine, and improve the thermal environmental performance of buildings. For example, in the inner and outer surfaces of buildings or between the outer layer and the structure, the roof is equipped with high-efficiency heat reflective materials, which can reflect most of the infrared rays, so as to play the role of thermal insulation for buildings. At present, the United States has launched large-scale production of heat reflective films for building energy conservation, while reducing the energy supply system. Reduce the emission of heat, waste gas and waste dust to nature

(2) make full use of climate resources. For example, most of the lighting and heating of electric motors (blowers) can be provided by sunlight, and the cooling is generated by flowing air, etc. to avoid the energy shortage and air pollution caused by the massive use of artificial lighting and mechanical air conditioning. In recent years, Tianjin, Beijing, Gansu and other provinces and cities in China have built 17 passive solar thermostatic houses, using the building itself as a solar collector, so as to achieve the purpose of indoor heating and cooling.

(3) save water, Waste water places can be set in the building
