Chinese Academy of Building Sciences: Research white paper on the application status of building intelligence in 2021

Based on more than 1000 questionnaires, this white paper analyzes the current application status of building intelligence, technical barriers and market challenges encountered in the development process, and combs the core needs of users; On this basis, this paper puts forward the application and development countermeasures and suggestions of building intelligence, and explores the development trend of building intelligence technology in the future.

With the continuous development of Internet of things technology, such as Bluetooth mesh and Lora With the continuous improvement of technologies such as NB lot and the application of 5g, Internet of things products and attributes can well solve the problems of wiring and configuration of traditional intelligent systems.

Personnel reserve: strengthen the construction of intelligent system and the construction of operation and maintenance talent team, and help the construction field achieve the goals of 2030 carbon peak and 2060 carbon neutralization as soon as possible.

A higher degree of automation.

Deep application of big data.


Trend Outlook: new technologies such as artificial intelligence, big data and 5g have been rapidly applied and developed in smart homes and smart parks, but they are less applied in intelligent systems of public buildings.

Through the investigation and analysis of building intelligent integrators, operation and maintenance personnel and users, it is concluded that at this stage, building intelligent systems are mainly foreign or joint venture brands, especially building automation, lighting control and other systems, and foreign brands have occupied the mainstream market for a long time.

This problem has attracted the attention of the industry.

Multi terminal operation and maintenance management mode.

In order to solve the above problems and give full play to the value of building intelligent system, the following suggestions are made: at the system level: 1) improve the intelligent system detection, adjustment, acceptance and post evaluation system; 2) Improve energy-saving certification and reward policies for intelligent systems; Technical level: 1) establish and improve relevant standards for intelligent system adjustment, operation and maintenance management and post evaluation; 2) Standardized operation and maintenance data collection and analysis methods; 3) Strengthen the development and application of new technologies; 4) Improve controller capability; 5) Standardized point configuration requirements.

At this stage, ordinary users cannot easily and quickly participate in building operation and maintenance and management, and have less interaction with buildings..

After the intelligent system is put into use, about 40% of the systems have software or hardware failures in one year of operation, and less than 10% of the systems can operate stably for more than 5 years.

The debugging process of intelligent system is complex, long cycle and uncontrollable quality.


Based on the above research, The prospect of building intelligent technology is as follows: 1.

Internet of things products will get a lot of opportunities in the intelligent system of office and commercial buildings.

If the system failure or disconnection is not found in time, the system will continue to be in unknown failure, which may bring hidden dangers of operation and maintenance safety.

Equipment and systems with configuration free, self identification, plug and play and flexible networking characteristics will reduce the workload.

From the perspective of front-line workers in the industry, this white paper focuses on the application process of building intelligence, discloses the pain points and difficulties existing in the application level of the industry for more than 30 years, and puts forward suggestions on the efficient implementation and implementation of intelligent system from the perspective of system and system, standards and technology, talent training and capacity-building.

Configuration free, self identification, plug and play, self-organizing systems and products more meet the needs of users.

In order to objectively understand the current situation of intelligent application and explore the development direction of intelligent building, relying on the national key R & D plan project of the 13th five year plan, the research group carried out research and Research on the current situation of intelligent application of building.

Under the guidance of the rapid development of new technologies, the diversification of people’s living needs and the realization of the national dual carbon goal, intelligent buildings are upgrading to intelligent buildings.

About 50% of operation and maintenance personnel basically understand the significance of intelligent system platform parameters.


The operation and maintenance based on mobile terminal and BIM is still in its infancy.

The system that can start and stop automatically and remotely is about 30 ~ 40%.


The use effect of complex control logic such as system optimization control and group control is poor due to various reasons.

Shorten construction period and save cost.

For example, various devices have obtained a large amount of construction big data, but their value in construction, system operation and maintenance management has not been fully explored.

With the in-depth application of artificial intelligence and the continuous improvement of the function and performance of intelligent robots, the building intelligent system will develop in the direction of unmanned operation.

I believe that with the continuous improvement of the system and the continuous efforts of employees, construction big data will play an important role in operation and maintenance management, energy conservation and comfort.

The research shows that at this stage, the application level of building intelligence in China is uneven, and the advantages of high efficiency, energy saving and convenient use of the system have not been brought into full play.

The survey shows that at this stage, only about 30% of the systems have achieved a certain degree of integration, but the data has not been interconnected, and the subsystems operate independently.

Based on the survey samples, this white paper analyzes the application status of building intelligence system in China, combs the main problems existing in each construction stage, excavates the core needs of users, and explores the future development direction of building intelligence from the dimensions of technology, system and policy.

Under the current framework system, the connection and configuration of field equipment and controller occupy a lot of human and material resources, but the application effect is poor.


The application of big data has penetrated into all aspects of work and life, providing benefits for people.

At this stage, the intelligent system is mainly managed by people.

Due to the uneven professional knowledge and cognitive level of operation and maintenance personnel, the faults of intelligent system can not be solved in time, and the full-automatic operation control function can not be fully utilized.

With more than 30 years of development, China’s intelligent buildings have transformed from nothing and from “new things” to “standard configuration”.

About 38% of HVAC systems can be used normally; 50% of the system point data is basically accurate, and there are many problems in the system platform, such as incomplete point monitoring, lack of key points and so on.
