In order to maximize the use of natural resources and reduce energy consumption, buildings are increasingly promoting active optimization and passive design. For some public buildings, in order to reduce energy consumption and increase the appearance of the building, the roof will be designed as a daylighting roof, but the large glass skylight may cause the result of cold winter and hot summer; if it is directly designed as a concrete floor, it is necessary to use lighting to provide brightness. At the same time, the mechanical and electrical system of the large-space structure construction is also difficult. Scaffolding needs to be erected from the ground for high-altitude operations. Therefore, it is necessary to design a method that is convenient for construction and meets fire protection requirements. To sum up, it is very important to coordinate and unify multiple factors such as daylighting, energy consumption reduction, meeting fire protection requirements, and convenient construction.

There are following defects in existing roof construction technology:

1. At present, the roof adopts a fully enclosed structure or a tiled skylight structure. The former has no lighting, and the latter has poor ability to independently adjust the temperature in the building.

2. Public buildings are generally designed as large-space structures. For cast-in-place structure construction at a height of more than ten to tens of meters, a full hall of support frames needs to be erected. Green construction requirements.

3. The construction of the electromechanical system of the large-space structure is also difficult, and the high-altitude operation has great potential safety hazards, which is not conducive to safe and civilized construction.

4. Install the photovoltaic panels after the construction of the normal insulation layer is completed. The installation of the photovoltaic panels requires expansion bolts to fix them, but the expansion bolts will damage the insulation and waterproof layers. Ordinary insulation layers are not suitable for this type of installation.
