Description

Technical Field

[0001] The present invention relates to the technical field of walls, and in particular to an energy-harvesting and energy-saving component, an energy-harvesting and energy-saving wall and a wall assembly method. Background Art

[0002] As an important part of the building's external envelope structure, the building's wall facade is a carrier that directly expresses architectural art and greatly affects the building's energy consumption level. The construction industry shoulders the heavy responsibility of energy conservation and emission reduction and achieving green and sustainable development. Reducing building carbon emissions, promoting energy structure adjustment and the development of green and low-carbon fields, and helping to achieve major strategic decisions on carbon peak and carbon neutrality are the top priorities of the future construction industry.

[0003] Buildings are the main source of energy consumption and carbon emissions, and the building envelope is one of the key factors affecting building energy conservation and carbon reduction. The vertical interface of the building wall provides more possibilities for the use of solar photovoltaics. In addition, photovoltaic modules also have the function of building materials, which can save costs in the construction process. They can serve as part of the wall facade, thereby reducing the demand for traditional building materials and reducing the overall cost of the construction project.

[0004] Renewable energy, mainly solar photovoltaic utilization, has the greatest potential for achieving energy-saving production capacity in building envelope structures. Integrating solar photovoltaic technology into the facades of buildings and realizing integrated building photovoltaic design can transform buildings from energy consumers to energy producers and from the main source of carbon emissions to a key factor in solving the climate crisis. It will help improve the energy structure and reduce building energy consumption. It has broad application prospects and important research value.

[0005] As an important part of the vertical interface of the building's external envelope structure, the traditional building wall only has the functions of bearing, enclosure, and thermal insulation on the vertical interface. In terms of the use of solar photovoltaics, the traditional wall structure is incompatible with photovoltaic thermal panels. After the wall is completed, it is installed twice, and the integration of building walls and renewable energy based on solar photovoltaic utilization is not achieved. Moreover, the common ordinary walls currently cannot make good use of green and clean renewable energy such as solar energy and heat source air of air source heat pumps, resulting in a waste of energy, which does not meet the standards of green buildings.
