green buildings
in western developed countries, energy saving and green buildings have a history of successful development for decades. Some countries have even made outstanding achievements in economic development and sustained decline in energy consumption. Timely, systematic and extensive introction of their successful experience and technology is particularly important to guide the development of energy-saving and green buildings in China. This is irreplaceable for us to avoid detours and speed up the promotion of new technologies, new procts and management experience of energy saving and green building< In recent years, the pilot construction of ecological buildings and health buildings in the United States has been very active, and the ecological buildings with characteristics have been built:
1. The University of Notts has designed and built an ecological house. This four bedroom ecological house has excellent heat insulation performance. Its heat energy comes from artificial heat dissipation, sunlight and the use of household appliances. Household electricity is provided by wind turbines and solar cells installed in the pavilion. The water is rainwater from the eaves, stored in the basement, filtered by sand bed before use, and the feces and sewage flow into a composting pit for garden fertilization after fermentation
2. Ecological villages in the United States. 150 ecological houses, called ecological villages, have been built on the 488 hectare island of Davey Abbey in Southern California. It retains its original natural appearance without any trace of man-made destruction. When building these ecological villages, the designers used the method of sharing to replace the previous single residence, such as sharing an energy center, a gas boiler, a domestic water heater and a ventilation system for every 6-8 residential units. But there are still some elements of living alone, such as each family still has its own bedroom, bathroom and kitchen. It is estimated that the energy consumption of residents in this ecological village is only one fifth of the original residence
3. American plant architecture. In the early 1980s, the United States built a magnificent ecological building in Chicago. There were no brick walls or slab walls in the building. Instead, plants were planted in the place where the walls should have been set to separate each room. People called this kind of wall "Green Wall" and this kind of building "plant building". The construction method of this kind of building is not complicated. It does not need timber or heavy construction equipment. Instead, it uses local materials, takes the forest as the main material, and uses regular living forest to do "top beam", "substitute residence" and "substitute wall". By using the popular "bending method" and "connecting method", many ingenious, novel and interesting arcades, curved bridges, screens, paddocks, shopping malls, residential buildings and office buildings have been built
4. American green hotel. In order to meet the public's requirements for environmental protection, the United States has built a unique green hotel. Half of the hotel's building materials come from recycled aluminum, glass, iron, steel, etc. The articles in the hotel should be "safe" as far as possible, such as envelopes and letter paper without acid, soap refined with vegetable oil, washing powder without chemical synthesis, sheets and towels without chemical fiber, but made of cotton or flax free from pesticide and chemical fertilizer pollution
5. New solar buildings in the United States. The American solar design association is developing a new type of solar residential building, which is called building integrated design. Instead of installing a heavy device on the roof to collect solar energy, semiconctor solar cells that can convert sunlight into electricity are directly embedded into the walls and roof. The idea of building integration was advocated by Steven strong, the founder of the association, 20 years ago, when solar cells were too expensive to implement. Today, the price of solar cells is only one third of that in the 1980s, so the possibility of promotion is greatly increased. The reason why power suppliers are attracted is that solar cells can generate excess power ring the peak hours of the day, thus forming a power reserve that can be used at any time. According to the integrated design concept, the U.S. Department of power supply and the Department of energy are working together to develop some new building components, such as solar "roof panel" for residential roofs and "curtain wall" for commercial buildings
6. In order to protect the environment and save the earth's resources, an American construction company built houses with recycled garbage, creating a new initiative to solve the problem of future housing. This kind of house is called "resource protection house" and "garbage house". They built four bedrooms, two bathrooms and a garage for two cars on a 360 square meter floor. At the same time, the interior furnishings are complete. The frame of the house seems to be very simple. It is mainly made of recycled steel from old cars and bridges. The exterior decoration is made of sawst and broken wood plus 20% polyethylene. This not only reces the use of wood, but also does not attract termites like wood, making the house more solid and safe. The characteristics of waste building are that 65% of metal, paperboard and wood waste can be recovered on site when building houses, which solves the problems of comprehensive utilization of waste and environmental protection. Because it is practical, economical and feasible, the company won the national residential style award of the year
7. Green office buildings in the United States. Mobil has built a green office building with a building area of 62000 square meters. With the support of the U.S. environment agency, this office building has achieved good technical and economic results in saving money and improving indoor air quality e to its reasonable design in material selection, lighting efficiency, recing heating and cooling load, ventilation and improving building functions. Less than one year after the completion of the office building, the relevant cost can be saved by 115700 US dollars, and the energy consumption of lighting and equipment can be reced by more than 50%
8. Green office in the United States. Nrpc headquarters is a green office built on the principles of energy conservation, environmental protection and health, with recycled materials as the main materials. From the appearance, the office building is no different from the ordinary office building. But its walls are actually made of wheat straw and processed by high technology. But its firmness is not inferior to that of ordinary wood structure houses. The floor is made of waste glass, and the desk is made of waste newspaper and soybean resie. The most distinctive feature is that the outer wall is surrounded by a variety of creeping plants such as Parthenocissus. This green dress not only makes the office look beautiful and fresh, but also can adjust the air and make the room warm in winter and cool in summer, which is beneficial to physical and mental health
Germany
1. Ecological building in Germany. The first ecological office building was built in Berlin, Germany. The front of the building is installed with a solar cell with an area of 64 square meters to replace the glass curtain wall, which is no more expensive than the glass curtain wall. Solar cells on the roof supply hot water. The roof of the building is equipped with water storage equipment, which is used to collect and store rainwater. The stored rainwater is used to irrigate the grass on the roof. The water seeping from the grass returns to the reservoir, and then flows to each toilet of the building to flush the toilet. The grass and water reservoir on the top of the building can improve the climate around the building and rece the fluctuation of the temperature inside the building
2. Solar houses in Germany. German architect seido tehols has built a sun house that can track the sun by rotating on the base. The house is installed on a disc base, and a set of gears are driven by a small solar motor. The base of the house rotates with the sun at a speed of 3 cm per minute on a circular track. When the sun sets, the house will reverse rotation, back to the starting position. It tracks the sun and consumes only 1% of the house's solar power, which is twice as much as a solar house that can't normally rotate
3. Plant ecological architecture in Germany. Germany has built a distinctive residential area called "lair Grassland" in Hanover City, which is built according to "plant ecological architecture". The so-called "plant ecological architecture" refers to the integration of plants and living space according to the ecological balance in large quantities, which is the proct of the organic combination of ancient architecture and young ecology. In the residential area, 69 courtyard style houses on the upper and lower floors are scattered and orderly distributed. Each building has its own characteristics in appearance, and its internal design is also different. The structure of each building is made of brick and wood skeleton, and the four walls are made of wood, which makes it simple and unadorned. The living room is paved with hemp carpet or woven with corn husk or wheat straw, and the sofa is mostly made of pure cotton cloth, which meets the requirements of environmental protection. The design is elegant and clean, mainly with simple stripes, plaid or broken flowers, or even pure color. Furniture does not use hard furniture, but mostly use primary color wood furniture without spraying any paint
it is particularly worth mentioning that "lair Grassland" has built a green ecological road. This new type of highway is not only planted with towering forest belts and luxuriant flowers on both sides to prevent air pollution and rece noise, but also implemented greening on the road surface“ The road surface of "Laier Grassland" wears small holes and plants green grass in the holes. Under the protection of green grass, the road surface will not be affected by car rolling. As 70% of the road is covered with green grass, the reflection of sunlight on the road is greatly reced. Walking in the "lair Grassland" is like being in the embrace of nature. You can't hear the noise of cars running and the pungent smell of gasoline. It's very pleasant
4. Zero energy housing, a solar energy self-sufficient housing in Germany. A kind of energy self-sufficient solar house zero energy house was displayed at bhw exhibition in Germany in 1995, which left a good impression on visitors. This kind of residence used to be thought to be utopian and impossible, but today it has become a reality. This kind of 100% solar powered residence does not need electricity, gas, wood or coal, so it does not need chimneys and heaters, and no harmful exhaust gas is discharged into the air to keep the ambient air fresh
in the design of this kind of house, the plane open to the south is a fan-shaped plane, which can obtain high solar radiation energy. The wall is composed of lime sand brick, heat insulation material and decoration material with good heat storage capacity. Sunlight passes through the insulation and the heat is stored in the sand brick wall. In the daytime, the house is heated by the sun through the windows, and in the night, it is heated by insulation materials and lime sand brick walls< In recent years, the Netherlands has made remarkable achievements in the implementation of "green house". "Green house" in the Netherlands
