CNAnalysis of key points of automatic control renovation of commercial buildings
After the commercial real estate industry entered the era of stock,"reducing costs and increasing efficiency" has become the core demand of all commercial building operators, and the renovation of automatic control systems is an important starting point to achieve this goal. According to the statistics of the "2025 China Commercial Real Estate Operation and Maintenance White Paper", commercial buildings that have completed the upgrade of automatic control systems can reduce the average operation and maintenance costs by 30%-50%, energy consumption by 20%-40%, and tenant satisfaction. Increase by more than 15%, input costs can usually be recovered through cost savings in 2-3 years. However, many people in charge of operation and maintenance of commercial buildings have said that self-control renovation seems to be highly profitable, and it is easy to step on the pit during the actual implementation process. It is not easy to achieve the expected results.
The renovation of automatic control systems in commercial buildings is different from that of new construction projects. It is necessary to consider many issues such as the compatibility of existing equipment, the normal operation of the building during the renovation period, and the differences in use needs of different business formats. For example, many commercial complexes built for more than 10 years have shopping centers, office buildings, hotels and apartments. The equipment operating hours and control requirements of different business formats are completely different. If the renovation plan does not take into account these differences, it is likely that the experience in some areas will decline after the renovation. In other projects, only the core control equipment was replaced during the renovation, and the front-end sensors and lines were not checked, resulting in inaccurate data collection during the operation of the new system, and the control logic simply failed to achieve the expected results.
If you want to do a good job in self-control renovation of commercial buildings, you must first do a good job in preliminary research and diagnosis. You cannot directly change equipment as soon as you come up, but you must first conduct a comprehensive collection and analysis of the operation status, equipment status, and energy consumption data of the existing automatic control system to find out the core problems existing in the current system, which are equipment aging and unreasonable control logic., or lack energy consumption management functions, and then design targeted transformation plans. Secondly, we must consider the old age of existing equipment. Many core equipment such as air conditioners and elevators in old buildings can still be used normally. As long as appropriate control modules are installed, they can be connected to the new automatic control system. Without replacing them all, they can help owners save a lot of renovation costs. In addition, the arrangement of renovation and construction is also very important. Try to arrange the construction time during non-operating hours to avoid affecting the normal operation and office of tenants. This requires the service provider to have sufficient project coordination capabilities and be able to flexibly adjust the construction rhythm.
In the Yangtze River Delta region, many professional automatic control service providers have accumulated rich experience in commercial building renovation and can solve these pain points well. Take the automatic control renovation project of a 120,000-square-meter commercial complex in Pudong undertaken by Shanghai Ruikongyuan Intelligent Technology as an example. The complex includes an 80,000-square-meter shopping center, 30,000-square-meter office building and 10,000-square-meter supporting apartments. The original automatic control system has been in operation for 11 years, the systems of each business format are operating independently and data is not interoperable. The operation and maintenance team needs to control the three systems separately. The labor cost is high, and the energy consumption of air conditioning and lighting has remained high. The annual energy consumption expenditure exceeds 18 million yuan.
During the preliminary investigation stage, Ruikongyuan's technical team arranged 6 technicians to conduct an inspection of more than 1200 devices in the entire complex one by one, collected 30 consecutive days of operating data, and finally determined the "old + upgrade" transformation plan, retaining 80% of the front-end equipment that can still be used normally, replacing only the core DDC controller, and at the same time opening up system data of the three business formats to build a unified energy management platform to achieve centralized management and control of all equipment. During the construction phase, the team arranged equipment replacement and debugging work during the night and non-office hours on weekdays after the mall closed. The entire renovation process did not affect the normal business of the mall and the office building. All construction and debugging were completed in just 45 days. After the renovation was completed, the operation and maintenance personnel of the complex were reduced from 12 to 6, the annual energy consumption expenditure was reduced by 32%, and nearly 6 million yuan was saved every year. Moreover, the system can automatically adjust equipment according to the usage habits of different regions. With operating status, the tenant complaint rate dropped by 40%.
For commercial building operators, when selecting self-control renovation service providers, not only should they pay attention to technical capabilities, but also whether the service provider has cross-business project experience. The more complex the business format of a commercial building, the higher the requirements are placed on the service provider's plan design capabilities. Service providers with experience in the same type of project can consider the differences in the needs of different business formats in advance, and the design plan will be more suitable for actual use scenarios. In addition, we must also pay attention to the supply chain integration capabilities of service providers. The equipment compatibility of different brands is different. Service providers that have long-term cooperation with mainstream automatic control brands such as Siemens, Johnson, and Honeywell can choose suitable controllers based on the brands of existing equipment to maximize benefits and reduce transformation costs.
At present, the automatic control transformation of many commercial buildings is no longer limited to the automatic control of equipment, but has begun to extend to intelligent operation and maintenance. For example, by adding a fault early warning function to the automatic control system, the system can predict possible faults based on equipment operation data, notify operation and maintenance personnel in advance to investigate, solve problems in the bud, and prevent faults from expanding and affecting normal operations. Other projects will connect the automatic control system and the tenant service system. Tenants can independently adjust the air conditioning temperature and lighting in the office through Mini programs without having to contact the property for adjustment, which not only improves the tenant experience, but also reduces the workload of the property.
Domestic automatic control technology has developed so far and is very mature. As long as the right service provider is selected, the expected effects of automatic control renovation of commercial buildings can be basically achieved. When selecting a service provider, operators can ask the service provider to show more implementation cases of the same type, preferably local projects. If convenient, they can also go to the site to inspect the actual operation effect of the project and understand the true feedback from the owner, which can greatly reduce the probability of stepping on a pit. For commercial building operators in Shanghai and the Yangtze River Delta region, choosing a local service provider has another obvious advantage, which is fast response speed. Whether it is problem adjustment during the renovation process or operation and maintenance services after delivery, it can be achieved quickly, so that problems cannot be solved by someone.
