Solar energy and building integrated design needs to solve four problems

Vigorously promote the renewable energy in the country in recent years, against the background of the solar-thermal industry ushered in the rapid development, especially since the concept of solar energy and the building integration put forward solar-thermal enterprises enter the accelerated significantly in architectural design field. However,

in recent years, under the background of countries to promote renewable energy, solar thermal industry has experienced rapid development. Especially since the concept of solar energy and the building integration put forward enterprises enter into the field of architectural design of solar thermal accelerated significantly. However, the previous 'outsiders' - — Solar thermal enterprises -- — And the combination of architectural design institute is not plain sailing. Therefore, in the recently held the first solar building energy integrated system innovation awards ceremony, the Chinese real estate reporter had an interview with China architecture design group co. , LTD. , the chief architect Feng Xue, explores the construction design of solar energy requirements and expectations. According to statistics, as of the beginning of last year, there were 26 provinces ( Municipalities and autonomous regions) And more than 270 cities issued policy solar installation. In Beijing, for example, 'Beijing residential building energy efficiency design standard' DB11 - 891 - 2012 rules 'residential building should be designed living hot water supply systems, priority using industrial waste heat, waste heat and solar energy as heat source'. In addition, since March 1, 2012 implementation of the 'Beijing urban construction solar hot water system application management method' regulation, also within the administrative areas of the new urban residential building and domestic water demand and meet the requirements for the installation of public buildings, such as hotels, hotels, schools, hospitals, bathrooms, swimming pools, etc. Shall be equipped with domestic hot water system, and synchronization with the structure design, construction and installation, acceptance submitted at the same time. Through the modification and installation, encourage conditional existing buildings to use solar energy hot water system. China real estate news: green low carbon residential integration technology in the solution is the proportion of renewable energy? In particular, solar energy can achieve what percentage? From the point of view of green low carbon residential integration technology, solar energy is one of the most important technologies. China's green construction has been developing rapidly since 2008, to 2011 increased by 24 times, the contribution of solar energy is more and more big. Because, in the green low carbon residential integration technology solution of 'low carbon and healthy' links, such as passive energy saving, energy saving, renewable energy, land, water, health and environmental protection, solar energy has been widely used. However, from the point of energy saving effects TAB, the proportion of solar energy is not very big, often is 5% ~ 10%, but its role is still very important. 'China real estate news: from the perspective of solar technology design, China's solar energy and building integrated technology should pay attention to what issues? From the perspective of solar technology design, solar energy technology in China should focus on the following four questions: one is the key to solve the problem of the passive use of the solar energy. First of all, the residential planning and architectural design should be conducive to the application of solar energy, including towards kindness, using the shape, to maximize the use of solar energy. Secondly, in order to solve the thermal dissipation storage of cold region building, should be through heat storage materials to develop new products. In addition, still should solve in hot summer and warm winter area with hot summer and cold winter region, south, west, shading problem. Second, we must solve the key problems in the development of solar energy hot water. Solved, for example, China's top and high density residential development in the integration of solar energy and architecture, solar storage devices increase the sharing area construction, solar energy saving relationship with the interests of the real estate development, operation and maintenance, solar hot water system and auxiliary heating system ( Electricity, gas, ground source heat pump) The problem such as the rational use of. Third, solve the future development of solar heating and solar power generation. The application of solar energy, for example, empty harmonic heating technology and the use of solar energy photovoltaic building ( Housing) Between the public space, etc. Fourth, we must use the solar energy thermal pressure ventilation solution. , for example, using public middle empty house door model between the heat tube well ventilated, the use of solar energy hot kitchen and bathroom, ventilation shaft ventilation in order to prevent the smell.
