Description

Technical Field

[0001] The invention relates to the technical field of building curtain wall energy saving, in particular to a variable multi-layer curtain wall system and method for composite photovoltaic and biomass power generation and vertical greening. Background Art

[0002] In the context of climate change and the dual-carbon strategy, in view of the high proportion of carbon emissions in my country's construction sector and the obvious growth trend, it is necessary to actively take measures to save energy and reduce carbon emissions in buildings. With the continuous development of urbanization, the intensity of population concentration and land development has further increased, and the urban living environment has put forward higher requirements for the efficient, innovative and intensive use of existing spaces. These all reflect people's yearning for low-carbon production, a better life and a green ecology. As a non-load-bearing exterior wall enclosure of a building, the building curtain wall is developing in the direction of lightweight, multi-type, safer, convenient construction, long life, environmental protection and energy saving. Compared with the technical characteristics and conventional problems of traditional curtain walls (light pollution, thermal insulation effect, etc.), the intelligent breathing curtain wall (double-layer curtain wall) type has more outstanding application potential in reducing energy consumption and improving utilization efficiency.

[0003] However, there are three common problems with curtain walls on the market: Problem 1: Most existing intelligent breathing curtain wall systems rely on external lines to meet their power needs. Once the power is off, they will lose their original functions. Problem 2: Most photovoltaic glass curtain walls cannot flexibly adjust the deflection according to the solar incident angle, and the installation and fixing stability is poor. Problem 3: Traditional green curtain walls generally use climbing plants for greening and sunshade, which has high requirements for civil engineering loads and drainage, and the subsequent maintenance costs are high. The lack of energy-saving awareness also makes the economic benefits of multi-layer curtain walls low.

[0004] The various problems existing in the existing curtain walls have prompted the development of a new generation of building curtain wall systems in an intensive and sustainable direction. Therefore, a standardized, green, intelligent, and building photovoltaic integrated energy-saving curtain wall system is needed. On the basis of the original curtain wall function, the curtain wall variability is increased while the high-rise green view rate is increased, the pressure and disharmonious factors that permeate the city are alleviated, and physical and mental health is promoted.
