How to build a smart building ecology?

According to the latest Statista report, the global smart building market size is expected to exceed $120 billion by 2023, with system integration services growing at an annual rate of 19.2%. Google Trends data shows that "smart building integration" searches have increased by 230% compared to three years ago, and "elevator access control system integration" has become the fastest-growing long-tail term in the Asia-Pacific region (+180%). This marks a shift in building operations from single-device intelligence to cross-system ecosystem integration.

Technology integrates the three core battlefields

1. Deep linkage of security system

Through the API connection between the biometric access control system and the elevator control, the whole link of "face recognition-permission verification-floor direct access" is automated.

Typical case: Capital Tower in Singapore uses Google Nest API. When the video surveillance detects abnormal intrusion, it automatically locks the corresponding area elevator

AI video analysis integration technology can identify 15 kinds of dangerous behavior patterns and trigger the emergency evacuation plan of the elevator

2. Energy management efficiency revolution

The intelligent energy-saving elevator connects with the building energy management system (BEMS) to realize:

Intelligent scheduling of elevator clusters during morning rush hour reduces energy consumption by 15%

Combine Google Environmental Insights's carbon emission data to dynamically optimize the operation strategy

Measured data of a commercial complex in Tokyo: the annual electricity saving is 370,000 kWh after integration

3. Intelligent upgrade of space management

The building operation dashboard built through Google Data Studio can achieve:

The meeting room reservation system is linked with the elevator dispatching system to reduce the average waiting time by 42%

The digital visitor management platform automatically generates the passage path, and the elevator is ready before the visitor arrives

Google Technology stack enables integration practices

1. Technical agreement layer

BACnet/IP protocol to realize real-time collection of elevator status data (300+ data points per second)

Google Cloud IoT Core Processes communication data of 10TB level equipment per day

MODBUS RTU Ensure 99.99% communication reliability of the access control controller

2. Safety protection system

The Google Chronicle analysis platform is used to monitor the abnormal communication of equipment in real time

The permission management model based on zero trust architecture has a permission change response time of less than 0.5 seconds
