United States has a better standard of energy saving building systems


United States says energy-saving and environment-friendly buildings as "green architecture". United States green building criteria for building a better, that is, legislation energy and environment design (LEED for short), can be translated as ' energy and environmental design standard, the specification by the United States Federal Government. The specification includes the following six aspects of content, and assign points to quantify, are: sustainable development, 14 minutes; the efficient use of water, 5 points, energy and atmosphere, 17; materials and resources, 13 points, indoor environmental quality, and 15 points, design innovations, 5 minutes, a total of 69 points. According to federal regulations, government investment in building construction is in accordance with the requirements of green building standards for the design, construction, and encouraging real estate developers, private investment in the construction of buildings actively adopted green building standards. Green architects must obtain the appropriate qualification. Green building construction supervision and evaluation by the USGreenBuildingCouncil (the USGBC), the United States Green Building Council to perform. Is between the Government and the construction unit of the Organization of the third parties, strict adherence to LEED standards. Through an assessment, scores 26 points or more, the Government will be given to "green building" signs. In the United States, all comply with the LEED green building and green building is widely accepted by society. In our country, although there are also some related norms, standards, but is not systematic. We should learn from the United States development of LEED practices, and established a comprehensive system of regulations, standards and local refining and strengthening the practical, promote the construction of energy-efficient buildings.


Construction of buildings based on long-term and sustainable development


It is said that United States cities came to be this way, again in a few years is still like this, not more. Why is that? United States cities without large demolition, urban planning, in accordance with the plan step by step construction, house building, doing routine maintenance, tinkering with the old House, but the structure does not change, so changes in the overall architecture of the city is not very large, LEED sustainable development embodies this philosophy. Due to routine maintenance, and the air is clean, some older houses still look brand new beautiful, actually has a deep knowledge of history. Of course, we owe a lot of history of urban construction, with the rapid economic and social development, transformation of the old city, new city building with each passing day, development has changed a lot. But there was blind construction and demolition waste, such as some buildings, bridges built today and soon were removed for various reasons, causing a massive waste of resources and energy, it is a pity.


Committed to energy-saving buildings and nature as a whole


Buildings take full advantage of natural energy and resources are a great way to save energy. United States many of the practices for reference. Such as the use of natural light. We visit the Newark high school, QUEENSBOTANICAL garden, clinics, offices, and so on, using solar power, heating, capable of providing buildings with around 40% of electricity supply, and with local area grid. Is also reflected in the use of natural light on the architectural lighting, United States many green building "variable angle sun visor + window", skylights, shaded in the summer, the winter maximum light transmission into the building, efficient use of energy. Another example is the use of ventilation, architecture roof designed wave lounge, so disturbance formed when the air passes through the breeze, increased ventilation and comfort. Another example is the use of local natural resources, Newark high school, QUEENSBOTANICAL garden of geothermal installations also provide electricity to the building and heating with a hot, environmentally-friendly and energy-saving. United States Federal Government building's timber demand, generally does not allow importing building materials from places far from the site, collected from local materials, saving time, saving freight, while building materials coordinated with the local nature, reflecting the beauty of harmony. Utilization reflects the construction of buildings on the natural terrain of the care, the previously mentioned QUEENSBOTANICALThe garden, its construction is the use of the Park's open space without vegetation, reduces damage to natural vegetation. Meanwhile, the building also used the roof, rainwater collection systems built the collection rain and rough cleaned and used for watering plants and so on. And the integration of nature is also reflected in the area of environmental protection, according to reports, green building exterior wall materials of strict limits on polluting gas emissions, United States Green Building Council for its rigorous testing. Indoor environment even more so, will test the materials used by the construction unit, materials do not meet environmental standards will be prohibited. Domestically some buildings throughout the us with such ideas, but traces of other natural knifed abound. In view of this, the construction of buildings should take full advantage of topography, minimal change in the original natural landscape full use of natural sunlight, wind, water and building materials, and nature-oriented integration, coordination, harmonization, efficient use of energy and resources.


Government is promoting building energy efficiency for the main


First of all, by the United States Federal Government-invested construction projects according to green building standards for construction, played a leading role model, which brought about the trend of building energy-saving buildings. United States GM, which they consider energy conservation measures taken by the Government to be a guide, and begin to build energy-efficient buildings. Other companies, including real estate development enterprise, see GM of this transnational group of companies are actively promoting green buildings, also followed suit, buyers began to choose green building market effects begin to emerge, and forming a virtuous circle. Lead to energy saving has become a strong force in promoting building energy efficiency for the Government. Secondly, incentives helped push energy conservation building renovation and construction. For non-construction projects invested by the Government, the Federal Government provided, through the United States Green Building Council rating meets green building standards, you can achieve different degrees of operating income tax-free. Green building ratings, on a voluntary basis, may be made by the employer to apply to the Government.
