Located at a major transport hub in Hong Kong, The Metropolis Tower—a Grade-A office landmark—has deployed Tongdy’s MSD multi-parameter indoor air quality (IAQ) monitors throughout the property to continuously track, analyze, and optimize indoor air quality. The rollout strengthens the tower’s performance against green-building standards (including HKGBC’s BEAM Plus) and underscores its leadership in sustainability and healthy workplaces.
A Grade-A Sustainability Showcase
As a premier office address hosting multinational tenants, The Metropolis Tower aligns its design and operations with international best practices. Introducing an advanced IAQ monitoring system reflects its property-management philosophy: elevate tenant comfort and experience while improving energy efficiency and overall building performance.


Built for BEAM Plus Compliance
IAQ is a core component of BEAM Plus. By installing Tongdy MSD monitors, the tower has upgraded its capabilities in four key areas:
- co2 control: Adjusts outdoor air intake dynamically based on occupancy.
- PM2.5/PM10: Detects particulate spikes and triggers targeted purification.
- TVOC: Pinpoints sources of volatile organic compounds for swift mitigation.
- Temperature & humidity: Balances comfort with optimized energy use.
These enhancements raise the building’s sustainability profile and offer a replicable model for Hong Kong’s next wave of green buildings.
A New Benchmark for Smart Offices
With Tongdy MSD fully integrated, The Metropolis Tower is setting the pace for “5A” smart office buildings in Hong Kong. As the city advances its smart-city and sustainability goals, this implementation provides a practical blueprint for other Grade-A towers and transit-oriented developments.
How MSD Works at The Metropolis Tower
Across roughly 20 floors and ~500,000 sq ft of office space, Tongdy MSD monitors are installed in lobbies, lounges, meeting rooms, corridors, and high-traffic areas connected to the MTR. All devices connect to the building management system (BMS) for intelligent, closed-loop control:
- High co2? The system automatically boosts fresh air.
- PM2.5 exceedance? Air purification equipment switches on.
- Real-time data to cloud: Facility managers can track trends and act instantly.
This data-driven approach safeguards occupant health, improves energy utilization, and supports carbon-reduction and smart-city objectives.
What MSD Monitors
- PM2.5/PM10 for particulate pollution
- co2 for ventilation effectiveness
- TVOC for total volatile organic compounds
- Temperature & humidity for comfort and efficiency
- Optional (choose one): carbon monoxide, formaldehyde, or ozone
