● Through the energy consumption monitoring and comprehensive management of the air-conditioning and HVAC system, the system automatically adjusts to achieve energy saving and consumption reduction● Improve the comfort and operating efficiency of Beijing Yizhuang blue-collar apartments, and create a living space where people, buildings and nature coexist harmoniouslyIn the process of rapid urbanization, the construction industry, as one of the three "big energy consumers" alongside industry and transportation, is closely related to energy consumption and carbon emissions, and has undertaken an important mission on the road to carbon neutrality. The "14th Five-Year Plan for Building Energy Conservation and Green Building Development" proposes that by 2025, more than 50 million square meters of ultra-low energy consumption and nearly zero energy consumption buildings will be built, and prefabricated buildings will account for 30% of new urban buildings in that year.In the Beijing Economic and Technological Development Zone, the Beijing Yizhuang Blue-collar Apartment constructed by China State Construction Technology Group Co., Ltd. (“China State Construction Technology”) is a recent achievement of the green and low-carbon transformation of the construction industry. Yizhuang Blue Collar Apartment has 9 floors, a height of 32 meters, a construction area of 120,000 square meters, and an overall assembly rate of 92%. It is an AAA-level modular demonstration project with an ultra-high assembly rate in Beijing. It is recyclable and can provide more than 1,800 housing units after completion. It is currently the tallest and largest modular building in China.In the Yizhuang blue-collar apartment project, the core part of building automation control adopts ABB Cylon (Xilang) intelligent building control system. Through the energy consumption monitoring and comprehensive management of heating, air conditioning, lighting, cold and heat sources, water supply and drainage systems in the building, the comfort and operating efficiency of the building are improved, and the owner's needs for intelligent control and energy saving and carbon reduction are met. Environmental protection and low-carbon advantages of buildings.The Cylon intelligent building control system demonstrated its intelligence and flexibility in the project, meeting the requirements of energy saving, system stability, easy operation and easy maintenance put forward by China Construction Technology. Each local area controller of Cylon is a programmable controller, which can formulate different local area control modes according to the site conditions; Cylon monitors the use of electromechanical equipment in the entire building group in real time, and according to the change of each variable, the system Automatically increases or decreases energy (hot or cold). At the same time, the system reserves a variety of interfaces, such as: BACnet, Modbus, etc., to facilitate centralized monitoring of various systems and reserve redundant points to meet future expansion needs.Zou Enchang, head of ABB's smart building business in Asia Pacific, said that under the background of sustainable and digital economic development, ABB relies on cutting-edge technologies such as BIM, Internet of Things, big data and cloud computing, and is committed to strengthening the relationship with design, system integration, construction, operation, The all-round coordination of all parties involved in the owner builds a new digital building ecological system, empowers customers and partners to promote industrial transformation and upgrading represented by new design, new construction, and new operation and maintenance, and creates a harmonious coexistence of people, buildings, and nature. space.ABB is an innovative company in the field of smart buildings, committed to providing safe, smart and sustainable solutions, and becoming the industry's preferred partner. At present, ABB's solutions have been applied in many domestic landmark projects, such as: the integrated project that has obtained the LEED platinum certification of the green building evaluation system
