Although these materials have certain structural strength, they perform poorly in terms of thermal insulation and heat preservation. In addition, the existing technology also has certain limitations in construction methods. For example, there is a lack of an effective multi-layer material collaborative working mechanism, and the existing technology does not accurately adjust the selected exterior wall panel buckle structure, which has a significant impact on construction.

[0004] Chinese Patent Publication No.: CN109138146A discloses a low-energy assembled building, in which the exterior wall of the building is an assembled energy-saving double-layer curtain wall, the interior partition wall of the building is installed with phase change wall heating, the interior ceiling is an energy storage ceiling, the interior floor is an energy storage floor, photovoltaic thermal solar panels are installed on the roof and the exterior of the building, the building doors and windows use reverse phase change glass windows, the building's household water pipes are connected to the ground source heating water system, the hollow wall of the double-layer curtain wall is connected to the indoor air inlet, and the other end of the hollow wall is connected to the ground source heating fresh air system. The building with multiple energy storage systems of the present invention has the functions of autonomously providing indoor energy, hot water and fresh air, automatically regulating indoor temperature, saving energy and reducing consumption; and it is convenient to build, directly assembled and constructed, integrating ecological environment, ecological energy utilization and building structure, integrating the two systems of traditional architectural aesthetics and green building technology, and truly achieving a high degree of unity between ecological energy conservation and architectural innovation; the building structure also has multiple functions such as light weight, earthquake resistance, fire prevention, and sound insulation. It can be seen that the low-energy assembly building has the following problems: the building adopts a variety of advanced technologies and materials, such as assembled energy-saving double-layer curtain walls, phase change wall heating, energy storage ceilings and floors, photovoltaic thermal solar panels, etc. The maturity, reliability and high cost of these technologies may limit their promotion in large-scale applications.
