Smart Buildings That Work Smarter
AI-driven access, occupancy analytics, and energy management — turn your office building into an intelligent, low-cost, high-experience workplace.
Solution Overview
Retrofit-Ready AIoT for Existing Buildings
AI continuously learns each floor's occupancy pattern — adjusting HVAC, lighting, and meeting room availability before tenants even notice.

Pain Points & Approach
Office Buildings Are Bleeding Cost
Hybrid work shrank occupancy by 30–50%, but energy and security costs didn't drop with it.
Wasted Energy on Empty Floors
HVAC and lighting still run full-power on half-occupied floors — the #1 hidden cost in commercial buildings today.
Outdated Access Control
Physical badges, manual visitor logs, and unmanaged contractor access expose buildings to real security risk.
No Occupancy Intelligence
Operators can't answer 'how many people are actually here right now' — making space and HVAC planning pure guesswork.
Costly Retrofits
Most smart-building solutions require rip-and-replace — taking 12+ months and 7-figure budgets.
Typical Workflow
Install in weeks, not years. Wireless-first architecture that works with the wiring you already have.

Project Snapshot
Grade-A Office Tower, 35 Floors
Shenzhen CBD
Case Study
Background
A premium office tower with 40+ tenant companies and 5,000+ daily passes wanted to reduce post-pandemic operating costs without disrupting tenants.
Challenge
Hybrid work cut daily occupancy to ~55%, but utility bills barely moved. Visitor management was still paper-based.
Solution
Deployed AI occupancy sensing on every floor + multi-tenant access portal + AI HVAC optimization in 3 phases over 5 months.
