With emerald green building as the medium, it has undergone a crucial transformation in the overall planning, design scheme, engineering construction and even the medium and later management methods.
According to the rating, buildings can be listed into four grades: basic superior, Gold Award, special award and white award.

The construction of projects with a large total investment can be started six months in advance, which means that assets can be turned over as soon as possible.
Professional contracting qualification for construction: Environmental protection, decoration, electromechanical equipment, building curtain wall, ancient architecture and city And road lighting, electronics and intelligence, fire protection, waterproof, anti-corrosion and thermal insulation, steel structure, formwork and scaffold, foundation, lifting equipment, ready mixed concrete, bridge, tunnel, highway pavement, highway subgrade, highway transportation, railway electricity, railway track laying and girder erection, railway electrification, airport runway, civil aviation air traffic control, airport visual navigation aid, port and coast, waterway Navigable buildings, port and shipping equipment and water traffic management, hydraulic metal structure fabrication and equipment, water conservancy and hydropower electromechanical equipment, river and lake regulation, power transmission and transformation, nuclear engineering, offshore oil and special services.
Zhaocaimao headquarters is located in Chengdu, Sichuan, a “Little Hong Kong” in Southwest China, enjoying a “land of abundance” Laudatory name.
Nowadays, the cost of most design schemes is relatively disordered, so the technical cost estimate itself is very complicated In many cases, the change of cost is exaggerated or reduced.
The Ministry of Science and technology also has the application of assets and current policies.
The United Kingdom and Panama in the United States require that houses be rated a ~ g according to the energy consumption of houses, and all houses need to have “energy consumption rating qualification certificate” when they are sold from 2007 Like the energy consumption signs posted on refrigerators, automatic washing machines, sinks and dishwashers.
Property buyers refuse to be “emerald green” When buying a house, real estate developers make do with the lowest level of policies and regulations.

Yuan Bin said: “to encourage real estate developers to build green and energy-saving buildings, government departments should choose very important personas.” the reporter interviewed government officials in San Francisco and learned that the San Francisco Urban Construction Bureau issued a current policy in 2006: if the new projects newly created or expanded meet the LEED Special Award (LEED was formulated by the British Green Building Research Association) “Evaluation rules for leading design schemes of electric energy and natural environment” , buildings are assessed from five environmental protection perspectives.
Dozens of new projects are applied by the Ministry of finance every year.
Tibet (Tibet), Hubei (Hubei), Anhui (Anhui), Jiangsu (Jiangsu), Shanghai (Shanghai), Zhejiang (Zhejiang), Fujian (min), Hunan (Hunan), Jiangxi (GAN), Sichuan (Sichuan, Shu), Chongqing (Chongqing) , Guizhou (Guizhou, Guizhou), Yunnan (Yunnan, Yunnan), Guangdong (Guangdong), Guangxi (Guangxi), Hainan (Hainan), Hong Kong (Hong Kong), Macao (Macao), Taiwan (Taiwan).
As soon as the building is green, the cost of the project will be high.

The Urban Construction Bureau will review them six months in advance to encourage real estate developers to build green buildings.
Yuan Bin said: “In recent years, the Ministry of finance has allocated a special fund for the application of new energy technology in the construction field, with a subsidy of 60 yuan per square meter, and 10000 square meters is more than 600000 yuan.
He said: “The UK has organized cost calculation and statistical analysis of 60 buildings, including 30 emerald green buildings and 30 non emerald green buildings.
” Real estate developers have a wide range of scruples.
Third, even if the emerald green level of the comments is the same, because the “congenital standards” of buildings are different, the increase of cost will still be different..
Because government departments do not have additional subsidies or preferential policies for green buildings, this part of the cost can only be absorbed by real estate developers themselves.
First, according to China’s code for comments on emerald green buildings Three star or one star emerald green buildings, or Perkin or silver emerald green buildings with reference to international standards, their overall objectives and characteristics of emerald green are different, and the cost is certainly different.
Secondly, to improve the technical cost, the first thing to clearly refer to is what.
Compared with developed countries, China’s emerald green Construction started 15 years later.
The results show that it is difficult to distinguish whether they are emerald green buildings simply according to the cost.
With more than 10 years of intensive cultivation, our business has covered the whole southwest region and promoted to the whole country.
The pursuit of perfection of emerald green building is not the only performance parameter, so the increase of technical cost will vary according to work.
At present, there are more than 500 employees, the proportion of professional and technical personnel is more than 60%, and the number of registered technical talents with medium and high-grade technical titles and more than class I qualifications ranks among the top in the operation.
In Inspired by preferential policies, San Francisco, USA, has 44 green buildings verified by LEED, ranking among the “top ten green places in Britain”.
General contracting qualification for construction: construction, municipal administration, electric power, electromechanical equipment, highway, railway, port and waterway, water conservancy and hydropower, mining, metallurgical quality, chemical petroleum and communication.
The new research conducted by the Global Business Service Research Institute on the concept of sustainable development found that the professional staff of construction technology and the professional work of real estate The staff overestimated the cost of emerald green building by 300%.
Economic development factors immediately endanger the development trend of green buildings, Cost and profit problems are important to the feasibility of green buildings.
A manager of a real estate group told the publication: “if the following two problems can give the established answers to real estate developers, one is what risks I want to bear, and the other is whether I can see accurate profits, then the area where green energy-saving buildings are built will be much higher.” Lin Borong, a teacher of Tsinghua architecture school, is very skeptical about the cost calculation of emerald green buildings.
We started in Chengdu and took Shu as the mainland.
In that way, the technology of external wall insulation, window sash and the utilization of solar energy can only be used The large-scale application of floor heating in housing in Liaoning has a good practical effect, which is due to the excellent current policies and systems.
Planned cities: Beijing (Beijing), Tianjin (Tianjin), Heilongjiang (HEI), Jilin (Ji), Liaoning (Liao), Hebei (Ji), Henan (Yu) and Shandong (Lu) , Shanxi (Jin), Shaanxi (Shan), Inner Mongolia (Inner Mongolia), Ningxia (ning), Gansu (long, GaN), Xinjiang (Xin), Qinghai (Qing).
Com) is a company registered with Yongkang Administration for Industry and commerce, providing qualification, qualification handling, qualification agency, qualification transfer of various construction engineering qualifications, handling safety production licenses and providing talent services for construction enterprises (class I and class II constructor, middle and senior engineer, technician certificate, etc.) Enterprise management consulting company, providing efficient resource services for enterprise development.
In the project construction process, real estate developers are also worried that unprecedented problems will endanger the construction progress; property buyers don’t like it very much, and real estate businesses must make concessions.

Emerald green building seems to be a “three high” new project with standardization, high technology and high payment.
According to data and information in the United States, the cost of green energy-saving buildings is 20% higher than that of ordinary housing projects.
Experts and professors of Tsinghua architecture school, Tsinghua University Yuan Bin, deputy director of the office of the emerald green building design scheme and Engineering Project Consulting Center, informed that since the 1980s, the construction industry has quietly undergone a reform.
Therefore, the statistics mentioned above do not have much reference practical significance in a sense.
provides you with the latest construction information.
