In today's accelerated urbanization process, building energy consumption has accounted for more than 40% of the total energy consumption of society. What is shocking is that more than 60% of commercial buildings are still using backward manual management models, resulting in an average annual energy waste of up to 25%. The smart building integrated management system is an overall solution that came into being to solve this pain point. Through the Internet of Things, big data and artificial intelligence technologies, it integrates isolated building subsystems into collaborative agents to achieve comprehensive upgrades in energy efficiency management, environmental regulation, and security protection.
This system is like installing a ”digital brain” on a building. Its core functions cover four dimensions: the energy management platform uses smart meters, water meters, gas meters and other sensing equipment to monitor the energy consumption data of each floor and even each room in real time, automatically identify abnormal consumption and locate failure points; environmental control systemIntegrate air-conditioning, fresh air, lighting and other equipment to automatically adjust the indoor environment according to the flow of people, outdoor temperature and humidity, and light intensity; the security monitoring system builds a three-dimensional protection network through modules such as face recognition access control, perimeter prevention, and fire early warning; the facility management platform realizes the whole process from repair to maintenance.Digitization, automatic scheduling of maintenance resources and tracking of processing progress. After the Shanghai Central Building deployed the system, the air-conditioning system alone saved 31% of energy, and the annual energy saving exceeded 8 million yuan.
Depending on the scale of the building and the depth of renovation, the input cost is usually in the range of 50-3 million yuan. The specific composition includes: hardware equipment (30-45%), software platform (20-30%), installation and commissioning (15-25%), and training services (5-10%). It is worth noting that the return on this investment is very significant-most projects can recover their investment within 2-3 years: after a provincial government affairs center invested 1.8 million yuan in the renovation, it saved 860,000 yuan in energy costs in the first year, reduced operation and maintenance labor costs by 400,000 yuan, and reduced equipment failure rate.The indirect benefits of 60% are even more difficult to measure. At present, many local governments also provide subsidy policies, such as Shenzhen City's 20% subsidy for intelligent transformation projects.
This system is extremely scalable and can be flexibly configured like building blocks. For small and medium-sized buildings under 50,000 square meters, a standardized package plan can be adopted, focusing on the deployment of energy consumption management and intelligent lighting modules, and the investment is controlled within 500,000 yuan; large-scale commercial complexes require customized solutions, such as a 200,000-square-meter shopping center that deploys a system containing 3,285 monitoring points., to achieve fine-grained control of sub-regions and time periods; super-high-rise buildings need more professional design. The system of Shanghai Jinmao Tower includes a unique elevator group control algorithm and high-altitude wind speed response mechanism. Even old buildings in the 1990s can avoid large-scale wiring retrofits through wireless sensing technology.
Traditional building management is like "blind vision"-security guards stare at surveillance, engineering runs on-site, customer service answers phone calls, and the information of various departments is divided. The smart system has achieved three major breakthroughs: from passive response to active early warning, the system can detect equipment abnormalities in advance, such as the bearing failure of a cooling tower in an office building being warned 72 hours before the occurrence; from empirical judgment to data decision-making, the system optimizes the operation strategy through machine learning, and the Beijing Wealth Center adjusts the water pump through algorithms.Frequency, the annual power saving rate is 38%; from manual inspection to intelligent scheduling, maintenance work orders are automatically distributed to the nearest personnel, and the response time is shortened from an average of 45 minutes to 12 minutes.
The security system adopts a ”three vertical and three horizontal" protection architecture: three layers of terminal, network, and platform protection are implemented vertically, and all IOT devices are certified by the national secret algorithm; three lines of defense are established horizontally: data encryption, access control, and audit and tracking. The employee's authority is accurate to the operation authority of each button. Of particular concern is the privacy protection design. The system adopts an edge computing architecture, and the face recognition data is processed at the local terminal, and only the recognition results are uploaded to the cloud. The system has passed the level 3 certification of network security level protection 2.0, and has maintained a record of zero security accidents so far.
According to the "White Paper on Energy Efficiency of Smart Buildings" released by the Ministry of Housing and Construction, the average energy-saving rate of buildings deploying smart systems is between 25-40%: the lighting system is adjusted by human body induction and light induction, and the energy-saving rate generally reaches more than 50%; the air-conditioning system is dynamically adjusted according to the flow of people, and the energy-saving rate is 30-35%;The water supply system adopts intelligent pressurization and leakage monitoring, and the energy saving rate is 20-25%. The measured data of a park in Chengdu show that after the system is put into operation, carbon emissions will be reduced by 1,860 tons per year, which is equivalent to the carbon sequestration effect of planting 100,000 trees.
The system adopts a modular architecture, and the upgrade is as easy as installing an APP on a mobile phone. The expansion of functions is enabled through software authorization, and the addition of hardware adopts a plug-and-play design. When a conference management system was added to a bank headquarters last year, the function deployment was completed in only 2 hours. The maintenance service has also innovatively launched ”building health cloud hosting”, and the professional technical team remotely monitors the operating status of the system to detect potential problems in advance. Nanjing Deji Plaza has used cloud services for 5 years, and the system availability rate has remained at 99.99%, with an average failure response time of only 8 minutes.
This system has been widely used in various fields: the Shanghai Securities and Exchange Center realizes 7×24-hour unmanned operation and maintenance through the system, and the annual operation and maintenance cost is reduced by 45%; Beijing Union Hospital deploys a special medical version of the system, and the operating room environment pass rate has increased to 99.97%; Alibaba Xixi Park adoptsWith the smart office module, the utilization rate of meeting rooms has increased by 60%, and employee satisfaction has increased by 25 percentage points. The most exciting thing is the office building of a remote county government, which has realized intelligent transformation with less investment and saves 380,000 yuan in energy consumption annually, becoming a model for the construction of digital government affairs.
The smart building integrated management system is changing from ”optional” to ”just needed". With the advancement of the national dual-carbon strategy, intelligent transformation has become a key path for energy conservation and emission reduction in the construction field. It is recommended that building managers start with demand diagnosis, choose system suppliers with mature cases, and formulate phased implementation plans to rejuvenate traditional buildings with intelligent new life.
