Recently, the State Council to the SCS [2013] the document forwarded National Development and Reform Commission, Ministry of Housing and Urban "green building" program of action on building integrated solar proposed requirements. In this regard, industry experts said, solar cell thermal and building integration will usher in a new period of development, but this also need to improve the policy and in-depth research to promote it.
It is understood that the main goal of the program include: urban new buildings to strictly implement mandatory energy efficiency standards, "Twelfth Five-Year" period, the completion of one billion square meters of new green building; late 2015, 20% of urban new buildings achieve green building standards. The key tasks of the proposals include: really good grasp of the new buildings, energy conservation efforts, and vigorously promote the Existing Building Energy Saving; building large-scale applications to promote renewable energy.
The mandatory promotion policies and technical standards for building integrated solar thermal solar energy resources in appropriate areas should be introduced in 2015, the popularity of solar panel hot water, and actively promote passive solar heating. Safeguards, program policy incentives to increase financial support to study and improve the policy and objectives and tasks To The Green Building Initiative scientific analysis to the provincial government, into the provincial government energy-saving target responsibility evaluation and examination system.
Huozhi Chen, Secretary-General of the China solar charge controller thermal industry associations pointed out that, according to two industry media of more than 140 companies in the first half of 2012 independent research results show that the overall speed of some decline of the development of solar energy. But the engineering market growth rate reached more than 50%, there are some people in the industry think the engineering market a separate calculation of the construction market, called the fourth market. The introduction of a strong policy making solar thermal and building integrated usher in a new period of development.
It is understood that, Jiangsu, Shandong and other provinces and cities have introduced architectural layer below 12 after the acceptance of the standard by the project, greatly aroused the enthusiasm of solar energy companies, developers and consumers must install solar accessory products to also let the local overall supporting, household use, central heating, single-energy dual-energy combination of IC card metering and other new technology, which greatly promoted the development of solar technology and building integrated.
At the same time, however, the current national standards for solar installation yet introduced, the level of solar water heater technology, performance and quality requirements and building integrated still gaps. Most of the solar water heater installed on the roof of the slopes, all their own way, improper operation easy to damage the roof, resulting in leakage, a security risk, a common cause of complaints from owners and neighborhood disputes.
Huozhi Chen suggested that the relevant government departments should take the lead in the development of specific solar installation Implementing Rules and solar energy use and management of the implementation details, enhanced training, to avoid drawing review detailed planning program approval lax control, poor oversight of the construction process. Building green residential energy conservation, the to increase solar design should not be considered only after the project has started, otherwise the program is difficult to achieve optimal results.
Solar collectors embedded in the roof of the building, the exterior wall surface appearance of unity and concord, which is the initial stage of the integration solution. The combination of solar products and building should demonstrate link proposed combination of solar energy and construction issues. From the design when you consider how hot water solar system how placed, the details of what systems and auxiliary energy.
Beijing Tsinghua Urban Planning and Design Institute Building Branch, vice president Chen first spring agrees, he believes that the best solar energy and building integration is to build an integrated. From the planning stage of project orientation, solar products is necessary to intervene. At the design stage, it is necessary to communicate with the developers with no domestic hot water, and how to achieve the effect, reserved the position of plumbing construction.
