Tianjin Kerry Centre, Kerry Properties’ flagship mixed-use commercial development in North China, has introduced Tongdy’s PMD in-duct multi-parameter air quality monitors and TF9 outdoor air quality monitors to build a comprehensive intelligent environmental monitoring system. The system provides reliable data support for LEED, WELL, and RESET certifications, helping the project set a new benchmark for green and smart buildings in Tianjin.
Located in the core urban area of Tianjin, Tianjin Kerry Centre integrates premium office space, boutique retail, and high-end residential facilities. With a strong focus on low-carbon development, healthy living, and smart operations, the project is pursuing LEED, WELL, and RESET certifications, aiming to become a leading example of sustainable commercial development in the city.
To meet the requirements of international green building certification and support refined daily operation, Tianjin Kerry Centre adopted Tongdy’s PMD in-duct multi-parameter air quality monitors together with TF9 outdoor environmental monitors. This full-chain monitoring solution delivers key environmental data for certification review while supporting the green transformation of a high-end commercial complex.
Project Background: Green Buildings Become a Mainstream Choice Under Carbon Reduction Goals
Driven by China’s dual-carbon goals and the growing demand for healthier built environments, premium commercial complexes are accelerating their shift toward greener, healthier, and smarter operations. LEED, WELL, and RESET are widely recognized international certification systems, focusing respectively on sustainability, occupant health, and air quality.
As a landmark project in Tianjin’s central business area, Tianjin Kerry Centre brings together diverse functions and a large, highly mobile population. This creates higher requirements for indoor air quality control, energy efficiency, and occupant comfort. By taking international certification as a key driver, the project introduced professional environmental monitoring equipment to establish full-area intelligent monitoring. This strengthens its operational capability, enhances project competitiveness, and helps attract more premium enterprises and institutions.
Technical Solution: Tongdy PMD + TF9 Meets International Certification Requirements
Tianjin Kerry Centre selected Tongdy’s PMD induct multi-parameter air quality monitors and TF9 outdoor air quality monitors for their high-precision measurement, modular design, broad system compatibility, and certification-oriented performance.
The devices have obtained international certifications, including RESET, CE, RoHS, and FCC. Their monitoring data can be used to support LEED, WELL, and RESET certification reviews, helping the project move forward with greater efficiency and compliance.
Key Monitoring Parameters
The system monitors major indicators required for green building and indoor air quality certification, including PM2.5, PM10, CO₂, TVOC, temperature, and humidity. Optional parameters include ozone, formaldehyde, carbon monoxide, and noise.
Key Technical Advantages
The PMD and TF9 system is well-suited to the complex operating environment of a premium mixed-use development.
Its high-precision compensation algorithm helps reduce environmental interference and ensures stable, reliable data across office towers, retail spaces, apartments, and hotel-style environments.
The modular parameter design allows the system to go beyond standard air quality monitoring and add more environmental indicators as certification or operational needs evolve.
The system also offers strong network compatibility, supporting RS485, WiFi, RJ45 Ethernet, LoRaWAN, and 4G, as well as integration with BMS, IoT platforms, and other management systems.
For indoor applications, the in-duct PMD solution delivers strong cost-effectiveness. By installing monitors in return air ducts within the same functional zones, the project can reduce the number of indoor monitoring points while maintaining systematic and representative air quality data.
Deployment Plan: Full-Area Grid Coverage and Closed-Loop Intelligent Management
Tianjin Kerry Centre has deployed around 60 Tongdy PMD in-duct air quality monitors and TF9 outdoor air quality monitors. The devices are arranged in a grid-based layout covering office areas, retail areas, residential areas, and public spaces, enabling broad monitoring coverage across the entire project.
At the same time, a central intelligent management platform has been established to create a closed-loop process of monitoring, analysis, optimization, and feedback.
Monitoring Locations
In the premium office areas, monitors are installed on office floors, in meeting rooms, and in lobbies to support a healthier working environment.
In the boutique retail areas, monitoring covers shops, corridors, rest areas, and atriums, helping create a safer and more comfortable shopping experience.
In the high-end residential areas, devices are placed in entrance lobbies, elevator areas, and shared spaces to improve comfort and health protection for residents.
In public support areas such as parking facilities, equipment rooms, and fire access routes, the system monitors harmful gases and supports public safety management.
Intelligent Management System
The project uses a dual communication approach. Indoor monitors are connected through Ethernet, while outdoor monitors use 4G communication. This ensures stable data transmission while keeping network deployment costs under control.
The real-time data platform supports visualized data display, intelligent comparison, and tiered alarms. When abnormal conditions occur, the system can trigger pop-up alerts and SMS notifications, allowing the operations team to respond quickly.
Historical data is stored through both the BMS and cloud server, providing a reliable record for certification review and ongoing facility management.
The monitoring system can also be linked with air-conditioning, ventilation, and purification equipment, enabling smarter control and helping reduce energy consumption.
Application Value: Certification, Health, Efficiency, and Industry Demonstration
The system supports Tianjin Kerry Centre in meeting advanced LEED, WELL, and RESET requirements, helping the project strengthen its green building profile and quantify the value of a healthier built environment through reliable data. This also enhances the project’s brand image and leasing appeal.
With continuous monitoring of PM2.5, TVOC, CO₂, and other key parameters, the system helps identify environmental risks in real time. Linking with HVAC systems improves indoor comfort and supports occupant satisfaction of over 95%.
The intelligent monitoring platform also improves operational efficiency. Automated inspection reduces reliance on manual checks, cutting operation and maintenance labor costs by more than 30%. Dynamic equipment optimization helps reduce HVAC energy consumption by around 15%, supporting both low-carbon operation and cost efficiency.
Beyond the project itself, the deployment creates a replicable model that integrates environmental monitoring, certification support, and smart operation. It provides a practical reference for other commercial complexes pursuing green and intelligent upgrades.
Implementation Results: Stronger Green Operation and Steady Certification Progress
Since the system was deployed, Tianjin Kerry Centre has achieved clear improvements in green operation.
Air quality has remained stable, with CO₂, PM2.5, and TVOC levels consistently meeting international certification requirements and relevant national standards.
Operational efficiency has improved significantly, while energy consumption has been reduced, supporting the project’s low-carbon development goals.
The certification process is also moving forward steadily. Tianjin Kerry Centre is pursuing LEED Platinum, WELL Platinum, and RESET certification, expected to become Tianjin’s first mixed-use development to secure all three top-tier international green building credentials.
