Low carbon creates overall energy saving?

The following is the related content of overall energy saving of low-carbon buildings brought by Zhong Da Consulting for your reference.

In March this year, Yao Wang, an overseas student from China in new york, moved once. He chose his new home in a low-energy building.

Yao Wang's classmates in England sent him another message. A draft of "Energy-saving and Consumption-reducing Strategy" issued by the British government makes people realize that "low-carbon" housing is inevitable. It is clearly pointed out in the draft that by 2050, all completed houses in Britain should achieve "zero carbon emission".

People who feel the "low carbon" wind also include residents of Copenhagen, Denmark, which has announced that it is expected to become the world's first carbon-neutral city in 2025.

Reducing carbon emissions has become a global "energy saving and environmental protection" action.

There is no doubt that this trend is what Ran Li yearns for. He is the sales manager of an energy-saving parts manufacturing enterprise in China. For several years, he has been promoting the concept and products of green energy saving. Customers often give him the answer: "The product is very good and the price is a bit high."

And if green building becomes a trend or a necessary condition, the price will not be a problem. From another point of view, the operation of energy-saving products will mean a significant reduction in operating expenses in the later period. However, Li Ran regrets to see that external factors such as lots and residential facilities are still the yardstick for buyers.

He may not understand that promoting the trend of green buildings has also become the goal of some real estate practitioners in China. In the team that works hard for this, a name is expected to be talked about by people in a few years; "West Haff China House".

After last year, "CIHAF China House" once again submitted its "Green Manifesto" to the society; Green building technology system of "2009 China Pavilion of Cihaf". In this technical system, "complete solution" and "full life cycle" are the core, which has also become a powerful guarantee for "CIHAF China House" to implement green.

Realizing "low-carbon building" requires overall energy saving.

Li Dexiang, director of the expert committee of "CIHAF China House" and a professor at the School of Architecture of Tsinghua University, believes that the main means for the construction industry to contribute to energy conservation and emission reduction are ecological construction at different levels, eco-cities and green buildings in eco-blocks, and the strategic goal of eco-cities is low carbon.

"As the only binding multinational agreement in the world that requires countries to reduce emissions, the main provisions of the Kyoto Protocol will expire in 20 12. The Copenhagen conference to be held at the end of this year will determine the global emission reduction agreement for 20 12 to 20 17 years. " Shen Hongming, managing director of Beijing Tiqiderun Energy Technology Co., Ltd. said.

What role should China play in such an international proposition and put it into action?

A study in climate group initiated by former British Prime Minister Tony Blair shows that building energy consumption accounts for about 40% of global terminal energy consumption. Simply improving building energy efficiency can reduce global carbon dioxide emissions by 71500 million tons in 2065438, which is equivalent to 27% of the estimated global emissions in 20 10.

"Building energy consumption is very important for reducing emissions," said Dong Chen, director of China business of Climate Group.

It is based on the global concern for low-carbon economy that "China International Habitat Center" takes "low-carbon ecological residential area" as its eternal theme.

In this sense, the consciousness embodied in "CIHAF China House" is undoubtedly ahead of schedule. How to run this awareness through the whole project is a test for the project team.

Yan Kai, deputy director of the Habitat Committee of China Real Estate Research Association and leader of the expert group, pointed out that green building has been rising in China for several years, and some developers use it as a selling point to promote real estate sales. However, there are very few developers in China who really understand the development of green buildings and actively promote them.

Shen Hongming also said, "Our goal is to tell developers how to build green buildings through a set of technical solutions."

In the building parts market, many parts manufacturers have played the banner of energy saving and environmental protection, and green building is undoubtedly realized by choosing energy-saving parts. However, Shen Hongming emphasized that "CIHAF China House" is definitely not a pile of energy-saving components, but emphasizes "organic combination" and "optimized design" to achieve the "integrity" goal of energy saving and sustainable development.

Turning to the green building technology system of "2009CIHAF China Pavilion", we can also notice that it takes "quality life and low-carbon life" as the primary display hotspot.

"Now the real estate industry has entered the quality era, and builders and buyers are more rational. Doing a good job in building quality depends largely on the rationality of the use of parts. " Zhao Guanqian, consultant chief architect of China Architectural Design and Research Institute, pointed out.

Qin, Chairman of Architectural Physics Branch of China Architectural Society, agrees with the above view. He added: "The most important thing in the real estate industry now and in the future must be quality, and quality includes many concepts such as green, energy saving and environmental protection."

The concepts of green, energy saving and environmental protection are supported by many technical systems. It is understood that the "2009CIHAF China House" green building technology system puts forward that in addition to the environmental creation and technical measures of residential buildings, the saving of resources and energy and the reduction of environmental impact are also closely related to the surrounding environment of residential buildings, such as the planning and layout of surrounding buildings, the convenience of surrounding transportation, the perfection of public service facilities, the rationality of workplace selection and the creation of leisure and office environment of public buildings.

"Green building is an advanced social development value. In the field of green building, there is no shortage of technology, but integration. " Yan Kai thinks that "2009CIHAF China Pavilion" provides a reference model for "integration and optimization".

Carry green to the end

Even so, it is still difficult for the design team to ensure that the building can achieve the expected energy saving and emission reduction targets in the later operation, because "property management and behavior energy saving after the delivery of the building are too important".

Therefore, the main idea of "2009CIHAF China Pavilion" is "full life cycle and sustainable development". At the beginning of selecting parts, the energy consumption in the production process was considered to some extent. After the optimization design is completed, the energy consumption of the building is obtained through simulation calculation.

"This is not enough. We will also provide a set of suggestions on environmental protection management scheme. When the project really lands, we also hope to monitor the later data and remind people how to achieve the energy-saving goal most reasonably with the data. Detailed suggestions can be provided by refining when residents should open windows for ventilation instead of using air conditioners to adjust indoor temperature. " Shen Hongming said.

"We want the owners to understand that energy conservation and consumption reduction are not only the business of government decision makers and designers, but only when each of us participates can we achieve our goals. From a realistic point of view, energy conservation means a reduction in the cost of living, which is the most realistic benefit for the people. " He said.

From the market point of view, when everyone can accept this idea, when green becomes a trend and creates a lot of demand, it can become an inexhaustible motive force for green buildings.
