Lingyun Curtain Wall Design and Research Institute always regards technological innovation as the source of growth and development, and constantly strengthens technical cooperation with scientific research institutions and advanced enterprises. It also cooperates with world famous curtain walls such as Germany's Gartner, Schüco and Harmon （HAM）. The Design Institute establishes extensive contacts and technical exchanges, tracks, learns, and studies the development trends of technologies, products, and markets in related international fields. Based on the research and development of innovative technologies with independent intellectual property rights, they jointly develop new products, new technologies and The new technology has been successfully applied in the design of some landmark buildings. In recent years, the design institute has carried out key R & D work on energy saving and environmental protection of building windows, doors and curtain walls. The Design Institute cooperated with the Munich University of Technology, Huazhong University of Science and Technology, and the Chinese Academy of Building Research to establish a double-layer curtain wall and photovoltaic curtain wall experimental station. Through experiments and research, major breakthroughs were achieved in key technologies. At present, the design institute's research on ventilation double-layer energy-saving curtain walls, solar photovoltaic curtain walls, new high-efficiency heat-insulating aluminum alloy doors and windows, and electric external shading shutters has reached domestic leading and international advanced levels.
Automatic part drawing drawing system based on BIM model
In the traditional curtain wall design process, the drawing of processing drawings often takes up considerable labor and time costs. At the same time, in the drawing process, because of the level and quality of the practitioners, the size and representation of the parts in the drawn drawings are often wrong, resulting in many unnecessary losses. Our company has always focused on expanding the application field of BIM technology in the industry, and strives to realize the automatic generation of curtain wall drawings by using the characteristics of BIM models. At present, our company has expanded based on CATIA software to provide professional solutions for the batch output requirements of curtain wall unit plate assembly drawings and part processing drawings, and lay a good foundation for the future docking of CAD and CAM to achieve digital manufacturing.

Laser scanning technology is one of the main ways to quickly obtain 3D models of spatial entities. It is mainly oriented to high-precision reverse 3D modeling and reconstruction. Laser scanning technology is a bridge that shortens the distance from BIM. Accurate 3D model data can guide the design of space visualization. For the changes in the construction process, 3D laser scanning technology can help us quickly and accurately grasp the changes and make quick and accurate plan changes. Compared with the traditional method, the 3D laser scanning technology is more conducive to the rapid and accurate model processing of changing conditions, and reduces the technical difficulty and cost of BIM work. Mastery of laser scanning technology will also greatly improve our BIM design application level.
UAVs equipped with high-definition cameras and smart chips are increasingly used in areas such as security surveillance, fire rescue, engineering surveying and mapping. Combining BIM, big data, the Internet of Things, and cloud computing, these technologies that break the traditional development model have begun to work in the construction industry, improving the level of industry informationization, and reducing the cost and increasing efficiency. After a period of study, our company has mastered the mainstream drone technology, tried its application in the field of building and curtain wall, and explored its application field that may be expanded, laying a foundation for further in-depth.

The progress of the engineering project depends to a large extent on the organization of the materials. For curtain wall professionals, profiles and surface materials as the main materials are often the key links among them. “System” will automatically analyze the high-precision BIM model, differentiate the main materials, automatically number and output the bill of materials, guide the ordering, processing and transportation through 4D information, and use the coding system to set the theory and The actual operation status is related, real-time interaction, and timely warning of the conditions that may affect the smooth progress of the project, which has achieved the maximum reasonable management and control of the main materials.
Photovoltaic curtain wall
Since 2012, the company has jointly established an experimental station with Huazhong University of Science and Technology to carry out research on photovoltaic curtain wall integration and comprehensive energy conservation. The paper "Calculation Method and Analysis of Photovoltaic Wall Power Generation" was published in the English version of the national academic journal Harbin Institute of Technology.
