Description

Green electric building material

Technical Field

The utility model relates to a building materials field specifically is new forms of energy electricity generation, photovoltaic application, green building materials technical field, especially relates to a green electricity building materials based on composite packaging material.

Background

With the increasing environmental protection pressure, the green development becomes the subject of the world economy increasingly. Ecological civilization construction and green development are improved to unprecedented heights in China, and building energy conservation is one of important measures for promoting green development.

Since the innovation is opened, the infrastructure construction and real estate investment of China are continuously increased, and the proportion of building energy consumption in the total social energy consumption is increased. Authoritative data show that the building energy consumption of China only accounts for 10% of the total social energy consumption at the end of the last 70 th century, and the building energy consumption is increased to more than three times of the total social energy consumption by the end of the 'twelve-five' period. As is known, more than 90% of the existing buildings and buildings under construction in China are high-energy-consumption buildings, and the energy-saving work of the buildings is far in priority.

The green building refers to a building which can save resources (energy, land, water and materials) to the maximum extent, protect the environment, reduce pollution, provide healthy, applicable and efficient use space for people and harmoniously live with the nature in the whole life cycle of the building. Compared with the traditional building, the green building has the advantages that the average energy saving rate is 58%, the utilization rate of a non-traditional water source is 15%, and the utilization rate of recyclable materials is 7.7%. The green building is a new thing, and the traditional building is upgraded to the green building, so that the green building material can not be widely applied.

The photovoltaic power generation combined with the building is a development trend of the current green building and is an important application form of the current distributed photovoltaic power generation. The Building can be classified into Building Integrated Photovoltaics (BIPV) and Building Attached Photovoltaics (BAPV) according to different installation modes of Building combination.

The photoelectric building integration is a new technology for implementing a green building strategy and realizing sustainable development of human beings. The integration of photoelectric buildings is a new field of building formed by organically combining building technology, art and photovoltaic power generation technology. The BIPV not only has the function of an outer protective structure, but also can generate electric energy for buildings. In the process of developing the integration of photoelectric buildings, the traditional building structure is fused with the modern photovoltaic engineering technology and concept, a photovoltaic power generation system takes a building as a carrier and is fused with the building into a whole, and the photovoltaic power generation technology and required equipment are taken as building elements and are brought into the whole process of building design, so that the solar system becomes an inseparable part of a building composition, the perfect combination with the building is achieved, and the building and the photovoltaic are not bonded as two layers of skins.

The installation mode of building integrated photovoltaic is that the photovoltaic cell and building materials such as tile, brick, building material, glass and the like are compounded together to form an inseparable building component or building material, so as to form a photovoltaic tile roof, a photovoltaic curtain wall and the like, and the requirement on photovoltaic components is higher. The photovoltaic module not only needs to meet the functional requirements of photovoltaic power generation, but also needs to give consideration to the basic functional requirements of buildings, and even can improve the aesthetic feeling of the buildings.

At present, the most widely applied photovoltaic building attachment in China is a common photovoltaic module which is installed on the original building, does not replace building materials or building components, and is directly installed on a roof or a photovoltaic system attached to a wall surface. The common photovoltaic module (the solar battery module is packaged by toughened glass) usually has larger mass, the weight per square meter of the common photovoltaic module reaches more than 10 kilograms, and at least reaches more than 12 kilograms per square meter by adding the mounting support structure. In the process of installing the building and the household roof, the weight is heavy, the labor intensity of installation is high, and the implementation is difficult; in some occasions, the building can not be installed due to the limitation of the building load bearing; the product has single appearance and is not easy to change to meet the requirements of different building aesthetics, and the like.

BAPV does not increase the water and wind resistance of a building. Moreover, BAPV can increase building loads, affecting the overall effectiveness of the building. In addition, BAPV also has the problem of repeated construction for building surfaces, which wastes building materials seriously. The BIPV is relatively more intelligent, is a future development trend, and is a main solar power generation system pursued by people today.

Therefore, those skilled in the art are working on developing a green building material based on composite packaging material for building integration of photovoltaic and electric buildings.
