Build the "Kaihong Secure Digital Foundation": Fuzhou Urban and Rural Construction & Development Group partnered deeply with Shenzhen Kaihong Technology. Centered on OpenHarmony technology and built on the "Kaihong Secure Digital Foundation," they equipped Jianzong Tower with a perceptive, self-deciding "smart brain," enabling cross-device interconnection of heterogeneous building equipment, unified data scheduling, and efficient service collaboration.
Unified device perception and collaboration network: Through the "Jianhong" operating system, it builds a unified device-sensing network and data governance system for the building, enabling full-domain intelligent collaboration across office, security, energy consumption, and operations & maintenance services.

Implementation Results

Jianzong Tower has become a perceptive, self-deciding "intelligent organic life form." As the first smart building model project based on OpenHarmony, it was selected as a "2026 OpenHarmony Leading Commercial Practice Case."
The building's operation and maintenance efficiency has improved significantly, and energy consumption costs have decreased notably. Through data-driven decision-making, building equipment lifespan has been extended by 10%-15%, asset value preservation and appreciation effects are remarkable, providing strong support for Fuzhou's low-carbon pilot goals.

Customer Testimonial
