China's first LEED-H green building project looks beautiful

According to the official microblogging message from the Canadian embassy, ​​the construction of 33 greenhouses in Haikou mangrove all-wood villa district, the first LEED-HOME certified green building project in China, was completed and completed. It is reported that this all-wood construction of the villa costing 150 million yuan, the full use of Canadian wood-based construction technology and design by the Canadian designer, and even the construction of timber is also the Department of Ocean Shipping. Reporters learned from official data that as of the end of August 2013, there were 1,347 different types of LEED certification projects (including Hong Kong and Macao regions) applied and certified by China.

In fact, China has become the world's second-largest LEED-certified country after the United States and has become one of the most enthusiastic LEED-accredited countries. The data show that LEED-CI (interior decoration) and LEED-NC (new construction) occupy the main part among the LEED-accredited projects, and there are many other categories of projects.

Interests behind the LEED heat cause trouble

LEED - Leadership in Energy and Environmental Design (LEED) is one of the leading green building certification awards in the United States and in the world. It was started in 2003 by the non-profit organization US Green Building Council (USGBC) . LEED-H is one of eight assessment categories.

In China's commercial real estate development process, regardless of what kind of attitude the project owner, apply for the United States LEED certification has become the industry consensus. Head of real estate prices and even admitted: "LEED is an international standard, companies can apply for success, but also to prove that the project has reached international standards, the added value is naturally high." This attitude has become devoted some real estate companies, Spared no expense, blind pursuit of LEED "international quality", then hype about speculation, as the company brand "luster" and to achieve a model of its additional business value. In this situation, LEED certification seems to have become a speculator with a close relationship with all stakeholders. More news pointed out that the US Green Building Council will not pay attention to inspection and review, just some of the parts prone to problems, and LEED some provisions even set up as long as the purchase of some foreign manufacturers of "green products", you can get points.

In addition, LEED fever is also not perfect and relevant to the current standards of our country. "The reason why LEED certification is prevalent in some developing countries is because these countries, because of the short development history of modern architecture, have not formed their own certification of energy saving and environmental protection standards. Therefore, they have to borrow the very scientific LEED Certification! "Said Robert Wastson of the U.S. Defense for National Resources, a leader of LEED" The Godfather. " Data show that Europe is recognized as the best living environment, but the number of its LEED-certified buildings are few. The reason, we can easily find that Europe has a very scientific and mature assessment of the building and certification system, such as: France ESCALE, Germany DGNB, Japan CASBEE and so on.

LEED certification program - looks beautiful

The Bank of America Tower was named "the greenest high-rise office building in the world" in 2010. Recently, the "New Republic Weekly" issued a document exposing the truth behind this hypothetical "green" skyscraper. It criticized LEED for being good at exaggerating the hype but not even the most basic The energy consumption can not be predicted. The data shows that the 55-storey Bank of America Tower is actually a high-speed, energy-consuming machine. It cost billions of dollars to build, expecting higher energy consumption. Frankly speaking, its energy efficiency is still not as good as that of the Goldman Sachs headquarters building, such as lower or even no rating scoring.

The reason for this is mainly due to the evaluation system and standards of the LEED certification system itself. In response, Tang Fen, president of China Everbright Ltd., a leading green building manufacturer and leader in residential industrialization in China, Evaluation, LEED scoring system is mainly from six parts to examine: sustainable sites, water conservation, energy use, materials and resources, indoor environment and playability categories. There are countless subdivisions in a standard scoring criteria, precisely because of cumulative points total standard system can lead to construction projects can be demolished East West to deal with clearance. For example, a project that spends millions of dollars on rainwater harvesting for a given project in the country is idle due to the high cost of wastewater treatment. There are countless examples of such indicators that are purely green and green.

A veritable factory to build China's green building

After 30 years of high energy consumption, high pollution, low quality, high speed overdraft development, the traditional mode of construction is rapidly declining. In the Chinese market, saving resources (energy saving, land saving, water saving, material saving) to the maximum extent and environmental friendly and healthy green building have become the consensus of the entire society. With the core concept of "green, safe, high quality and high efficiency" Industrial construction is the fundamental way to solve the problem.

Construction industrialization (also known as building industrial) core technology is integrated prefabricated prefabricated construction techniques, that the plant will be built in the form of house doors and windows, laminated floor, etc. produced in factories in good condition, the construction site just lifting, by mechanical technology Operation greatly saves energy resources and labor resources and ensures the quality and control of the whole cycle of design, manufacture, construction and operation, shorten the cycle, and green, that is, the manufacturing method of "green building" to achieve the harmonious coexistence of technology, environment and people. Architectural pattern. Tang Fen, president of Broad Resident, said that after 17 years of development and fully absorbing the advanced concepts and technologies from the United States, Japan, Germany and Singapore, the company has developed and adapted to China's national conditions, meets the requirements of current design codes and leads the international Prefabricated monolithic structure of reinforced concrete technology system, to solve the new technology and high cost of the conflict. Compared with the traditional construction method, it has many advantages such as controllable quality, controllable cost and controllable schedule. The construction period is only 1/3 of that in the traditional method. At the same time, the labor cost is greatly reduced. The construction site is free of dust, noise and sewage Such pollution can achieve 80% water saving, 70% energy saving, 20% wood saving, and 20% land saving. It realizes "five environmental protection" and solves the common problems of insulation, water impermeability and sound insulation and earthquake resistance. In Tang Fen's view, the industrialization of buildings is neither mysterious nor even the first creation of Chinese people, but rather an internationally accepted building technology. China Construction to do a five-green or to achieve international building industrialization level, the core business of "weapons" is still the advantages of technology and manufacturing, there is no technical innovation and first-class manufacturing level, it is not On the full sense of the green building.

January 6 this year, the National Development and Reform Commission and the Ministry of Housing and Urban jointly issued a "Green Building Action Plan", green building officially rose to the national strategic level, the green era of China's construction has arrived. We believe that with the active encouragement and guidance of state policies, with the promulgation of relevant standards and implementing rules of green buildings in various provinces and cities, our green building will surely realize the harmonious coexistence with nature. With a building history of 5,000 years, the Chinese architecture industry will achieve real green Chinese dream! (author: clothing salty)
