The sustainable development of architecture in the embodiment of a projectAll the civil engineering buildings and structures (including roads, bridges, ports, terminals, mines, tunnels, etc.) are made by materials according to certain requirements. The various materials used in civil engineering are collectively referred to as civil engineering materials.For a long time, human beings have been engaged in the various researches on civil engineering materials and constantly developing new materials. Almost all the materials in the world can be used as civil engineering materials. The project has adopted a variety of materials and here the following three types of materials are mainly analyzed.The first is steel, which is the collective name of iron alloy whose carbon content mass percentage is between 0.02% and 2.04%. The chemical composition of steel can have great changes and the steel only containing carbons is called carbon steel or common steel; in the actual production, steel often contains different alloy elements depending on the different applications. The preparation of steel is a high-cost and low-efficient work. Nowadays, the steel has become one of the most widely used materials in the world and an indispensable part of the building industry, manufacturing industry and people’s daily life for its low price and reliable performance.Steel structure work is the steel-manufacturing-based structure and is one of the main types of building structures. Steel is one of the common forms of structure in the modern construction works. Steel is characterized by high strength, light weight and rigidity, so it is particularly suitable for constructing long-span, super-high and super-heavy buildings; good homogeneity and isotropy, which make the material become ideal elastomer and mostly fit the basic assumption of the general engineering mechanics; good plasticity and toughness, which make the material able to deform largely and well subject to the dynamic loads; short construction period; high industrialization degree, which makes the specialized production of high mechanization level available; high machining precision, high efficiency and good air tightness. The disadvantages are the poor fire resistance and corrosion resistanceSteel structure can be divided into lightweight steel and heavyweight steel. The project mainly adopts lightweight steel structure. The roofing system inlightweight steel structure is composed of roof truss, structural OSB panel, waterproof layer and lightweight roofing tile, which is also named metal or asphalt tile. The appearance of the roofing in lightweight steel structure can have a variety of combinations. The materials are also various. On the premise of guaranteeing the technology of water proofing, the appearance has many alternatives. The wall of houses in lightweight structures is mainly composed of wall stud, top beam of the wall, the wall mudsill, wall support, wall panel and fastener. To ensure achieving the effect of heat insulation, the heat-insulating materials adopted in the external wall and roofing of buildings can be used for a long term, preserve and insult heat.Then is glass, which is a kind of transparent, high-strength and hardness, airtight material. Glass shows chemical inertness in the daily environment and does not react with living things, so it has extensive applications. Glass is generally insoluble in acid, but soluble in alkali, such as cesium hydroxide. Glass is an amorphous sub-cooled liquid. The melt glass cools rapidly and the molecules form glass as they do not have enough time to form crystals. In ancient times, glass refers to a kind of natural jade, also called talasite, not the present glass. Glass is solid at ordinary temperature and it is brittle. The hardness is 6.5mohs. Glass is, in deed, liquid. When the liquid cools, the originally turbulent and chaotic molecules will ultimately form ordered and regular crystal structure.In addition, according to its features, glass can be divided into: tempered glass, porous glass, i.e. foam glass, with an aperture of about 40 and mainly used in seawater desalination and virus filtering, etc., conductive glass, used as electrode and windshield glass, microcrystal glass, opaque glass, used in lighting and decorative items, etc., and hollow glass, used as door and window glass.Glass has many generalities. The first is the isotropy: the properties of homogeneous glass in all directions, such as refractivity, hardness, elastic modulus, coefficient of thermal expansion and so on are the same. Then is the metastability: when the melt cools to vitreous body, it can keep the structure in high temperatures at lower temperatures and does not change. Next is the reversible graduality: the transition from the melting state to the glass state is reversible and gradual. The last is the continuity: when the melting state transits to the glass state, the changes of the physical and chemical properties with temperature are continuous.The glass used in the project is tempered glass. It has high mechanical strength, good elasticity and thermal stability. It is not easy to wound people after broken and can be self-destructive.The last is wood, which is the lignified tissue formed by plants that can conduct secondary growth, such as trees and shrubs. After primary growth, the vascular cambium in the rhizome of these plants becomes active, develops bast outward and wood inward. Wood is the collective name of the plant tissues developed inwardly by the vascular cambium, including xylem and thin-wall radiation. Wood plays an important role in supporting human life. According to the different features of wood, people apply them to different uses.The tree trunk is composed of bark, cambium, xylem (i.e. timber) and pith. From the xylem on the trunk cross-section, we can see the annual ring around the pith. Each annual ring generally consists of two parts: the part in light color is called early wood (spring wood), which grows in the early season, has large cells and relatively loose material; the part in dark color is called late wood (autumn wood), which grows in the late season, has small cells and relatively dense material. The middle part of the tree trunk of some wood is in dark color, which is called heart wood; the side is in light color, which is called sapwood. The coniferous wood is mainly composed of tracheid, xylem ray and axial parenchyma, which are regularly arranged and the material is heterogeneous. The broad-leaved wood is mainly composed of vessel, wood fiber, axial parenchyma and xylem ray. The structure is complicated. As the cells making up the wood are directionally arranged, thus there is the difference between rift grain and cross grain. The rift grain can be distinguished from the radical direction coincident with the xylem ray; the chordwise vertical to the xylem ray. The coniferous wood generally has tall trunks and straight grain, is easy to be worked and dried, has small cracking and deformation and is suitable to be used as structural material. Some broad-leaved wood has hard texture, beautiful grain andThe flooring chosen for the interior finishing of the project is wooden floor. Wooden floor has various advantages. Firstly, it is beautiful and natural. The wood is natural and its annual ring and grain usually can make a beautiful picture, give people the feeling of returning to the nature and recovering original simplicity. Its texture has its own style and becomes a favorite among the masses. Then, it is a kind of material free of pollution. Wood is the most typical double-green product and it does not have source of pollution in itself. Some wood have tinctura aromatica, which gives off healthy and sedative smell; its sawdust is organic fertilizer that can be easily digested and absorbed by soil. In addition, it is light and strong and the general wood floats on the water, with few exceptions. Therefore, as a building material, wood is more convenient for transportation and laying compared to metal building materials and stones. Test results prove that, the tensile strength of pine wood is three times higher than that of iron and steel, 25 times higher than that of concrete and 50 times higher than that of marble; its compressive resistance is 4 times higher than that of marble. It can better embody its advantages especially asthe flooring (wooden floor). Then, it is easy to process. Wood can be sawed, shaved, whittled, cut and even nailed arbitrarily, so it can apply to the field of building materials in a more flexible way and play its potential role, while metal, concrete and stone do not have the function due to their hardness and they will cause waste or unrealistic circumstances. Next, it has good heat insulation. It is not easy for wood to conduct heat, while the heat conductivity of the concrete is very high. The heat conductivity of iron and steel is 200 times that of wood. There are many other advantages, such as adjusting temperature, strong durability, and easing the shock, etc.The executive director of the British ECOTECT company-Andrew Marsh thinks that “it is a moral obligation to design e nergy-saving and high-efficient buildings. If the client wants to save a very small part of the construction cost, but huge energy cost is caused in the 80 to 100 years’ service life of the building, then the architect has the obligation to prevent this fr om happening”. I am not surprised at all that Andrew holds a bachelor degree in architecture.Sustainable construction refers to the constructions planned and built following the principle of sustainable development, pursuing reducing environmental load, integrating with the environment and conducive to the health of residents.The sustainability of the project is shown in the following two aspects:First of all, modeling and material:Firstly, the modeling should be compact and try to control the contact area between the building and air. Secondly, adopt materials of low heat conductivity. The external wall adopts a large number of logs and some people think that only the construction adopting renewable materials like wood can be regarded as sustainable construction. Of course, there are people holding opposite opinions. Thirdly, the inner court is closed; the windows toward the inner court can be opened freely like traditional windows, but the windows in the external wall can not be opened freely, and its opening is controlled by the control center of the whole building, to ensure the orderly flow of the air. The three measures are taken to reduce the heat exchange between the skin wall and the air.In the second place, reduce the air heat exchange:Firstly, keep proper air tightness in the building; the inner court is closed, the windows in the external wall can not be opened freely, to ensure the orderly flow of the air. Then, make use of the ground-source heat exchange system to heat up the gases entering the building in winter and cool down the gases entering the building in summer. The ground-source heat exchange systemutilizes the characteristics of soil that the temperature is stable all the year round, takes the soil energy as the heat source of heat pump heating in winter and cold source of air conditioning in summer, that is, extract the heat sources indoors and release them to the soil with the temperature lower than the ambient temperature. The system is not complicated in technology and has great promotional value. According to the news from the network, the pilot of the technology has been launched in Tianjin and other cities of China. Finally, reuse the heat discharge. Use the air-conditioning heat recovery system that has quite mature modern technology, to conduct heat recovery to the hot air discharged outside the building.SummaryWith the constant advancement of the social civilization, the growing population and the increasing demand for resources of human society, the conflict between human and natural environment is becoming increasingly prominent. In the sixties of last century, scientists have proposed the concept of “sustainable development”. More and more people have realized that if we do not control the behavior of blindly taking resources from the natural world, not only the development of our descendants will be affected, but even the production and life of contemporary people will be affected. Therefore, this theory has been accepted by most countries and peoples in the world, and has received unprecedented attention.Building is one of the most important factors affecting the survival and development of human beings and it consumes a lot of resources. In the life cycle of a building, the proportion of energy consumed is the greatest portion of the energy consumed by human beings during the same period. Therefore, it is of great significance to promote the sustainable development of buildings for boosting the sustainable development of the whole human society.建筑的可持续发展在某项目中的体现任何土木工程建（构）筑物（包括道路、桥梁、港口、码头、矿井、隧道等）都是用材料按一定的要求打造成的，土木工程中所使用的各种材料都统称为土木工程材料。
