China's energy saving building still faces many problems to be solved: the reform of the northern region of heating, energy-saving renovation of existing buildings, new buildings to promote energy efficiency and how to lead more enterprises to join the buildings to energy saving in the current ... ... , "five" building energy efficiency research program has been initiated, I believe there will be a targeted solution available. In the periphery, long engaged in energy research experts believe that "good policy given to the building energy consumption" is a good path.
"Five" building energy efficiency plan has been launched, the plan you have any suggestions?
Li Dexiang: I think the lessons from the past, and good methods and techniques by extension. Specific to the operational level, the next step, the development of China from the perspective of promoting the city to promote construction of low-carbon energy, green building development.
In this process, to emphasize the diversity of low-carbon development path, complex, local and authenticity. Among them, the diversity is simply based on urban location, resources, choose the appropriate model of development. Currently, the ideal plan type, small-scale technology-optimized and both the city's transformation has become a low-carbon eco-city development of the three main paths, after years of development can be seen, most of the city should take the "both urban ecological transformation, "this road, although difficult, but the effect is obvious, especially for China, this road is more suitable, instead of making a large number of Metro; compound refers to the path of urban development to have multiple levels, including levels of low-carbon technologies, operation and management level, policy-oriented level, and social behavior level, multi-level complex operation to achieve the development goals; local is simply to local conditions, with local characteristics; energy saving requirements of authenticity is really practical, not to engage in window dressing, do not engage in the transfer of emissions.
Tan Wei Hong: On the "five-second" period, the continuation of the "Eleventh Five-Year" to develop some of the planning to ensure policy continuity.
In addition, we have to reflect on the "Eleventh Five-Year" during the lessons and achievements during this period, China implemented a number of building energy efficiency demonstration projects and development of new technologies, but in the end made what results is a summary and analysis of needs, that is what is going well and what needs to be improved, it is important is the need to quantify the evaluation, which for us in the development of "second five" plans to better position; Without a clear and quantifiable indicators, can not guide. " five-second "period of work. Renewable energy applications such as ground source heat pump and solar photovoltaic, solar thermal applications, you need to carefully study their adaptability. In fact, not all parts of these systems, are applicable to all projects of blindly copying the potential financial, manpower and waste of resources; What is more, in some places, the unit is in a state-funded cash subsidy costs. Therefore, a similar problem to the "five" period to avoid.
Lin Bo Rong: The Government should first take the lead in the implementation of government programs mandatory green building design. In addition, the new regional development and urban construction, green buildings, building energy efficiency will become a very important element into the inside, and even assessment of the government will gradually become an important indicator of job performance.
I have a bad forecast how it will specifically promote the development of green building, but we can practice from other countries to get inspired, which Japan and Singapore government a lot of experience is a good reference. Now, many countries including Japan, have mandatory requirements to external publicity of residential energy efficiency and green their performance, while banks and credit institutions will also do the green real estate project or business loans given to certain aspects of the concessions; Singapore government through the establishment of a special development fund to encourage real estate developers, research institutions, development of green building. These methods are worth learning.
Also, I think of green building as quickly as possible third-party evaluation and certification body is also very important.
Buzeng Wen: I think the "second five" things to focus on the following aspects: first with "society" on the construction of, a good balance to improve people's living standards and emissions-reduction targets; Secondly, in becoming more energy-efficient building conscious, the green building to become the focus of development; again, the majority of society is the total energy consumption of urban use, so we start from the urban ecological construction, so building energy planning; Fourth, policy constraints and incentives from the gradual transition to market-driven, building energy efficiency market is large, if the development of building energy efficiency industry is mature, well functioning market system, and building developers and owners of energy will become a conscious act; the fifth to be pragmatic, to develop appropriate goals.
In development, which policies and technologies should be vigorously promoted and promotion, and why?
Li Dexiang: From a technical perspective, one is to reduce carbon, to increase renewable energy supply and improve the efficiency of fossil energy, while making industry, construction, transportation, water and solid waste systems to reduce emissions; The second is to increase carbon sinks, carbon neutral. Specifically, to niche and Barrel principle as the guiding ideology of low-carbon technologies focused ultrasound technology integration, rather than simply piling up and the technology stack. For example, evaluation of the implementation of green building standards, energy consumption control as standard indicators are not only points accumulated through the technology options for the scores are often lobbied for the easier, the key options for energy saving is less able to do not do more, can not do not do. This may not be able to get certified buildings achieve energy reduction targets. For specific technical strategies have suitability issues, such as ground-source heat pump technology, is used the appropriate energy, used inappropriate then the opposite. From this we can see our green building evaluation criteria and evaluation process there is room for optimization.
Buzeng Wen: On the policy side, to improve existing building energy efficiency and green building standards, building energy efficiency standards for the implementation process to avoid the emergence of some loopholes, resulting in "energy-efficient buildings are not energy-efficient, green building is not green" phenomenon. At the same time, we must continue to explore the experience and energy-saving building practices to meet the needs of the market and the owners, scientific steady and orderly manner and the upgrading of existing buildings.
Lin Bo Rong: For residential purposes, such as adjustable sun blinds, hollow sound insulation windows, natural ventilation, rainwater collection and processing, building integrated solar water heater, air source heat pumps, green building materials, permeable brick and other costs appropriate, reliable, and can meet the real people living habits and to bring benefits of technology; for public buildings, the ground source (water) pump, temperature and humidity independent control technology, sub-metering, intelligent building control system is also a good technique.
How national policy should guide the green, low carbon building development?
Buzeng Wen: On the one hand, to expand the number of green building demonstration projects, so that more developers understand the green building, so developers can avoid detours; other educational buyers, what is good green building. Buyers market feedback information is more useful than the government enforce the command.
Lin Bo Rong: real estate developers in green building development play an important role in the development of green building developers should be as a business transformation opportunities, promote the upgrading of related technology products. However, developers can not blindly rely on conscious action to promote green building, we must push through government policies, people agree to make green building a real estate development and the pursuit of self-conscious behavior.
