Scandinavian Retail Meets Smart Monitoring Technology
In May 2026, the IKEA store in Auckland, New Zealand, completed an important upgrade to its underground car park ventilation system.
More than 20 Tongdy TKG-CO carbon monoxide controllers were installed throughout the parking area. By continuously monitoring CO levels and controlling the ventilation system according to real-time data, the solution helps maintain a safe environment while reducing unnecessary energy consumption.
Project Overview
ProjectDetails
Project Name IKEA Auckland Store
Location Auckland, New Zealand
Building Type Commercial retail store
Application Area Underground car park
Product Tongdy TKG-CO
Quantity More than 20 units
Application Carbon monoxide monitoring and ventilation control
Suitable Applications Commercial buildings, underground car parks, indoor air quality management, ventilation control and building automation
The Challenge: Managing an Invisible Risk
Underground car parks in large commercial buildings are enclosed or semi-enclosed spaces where vehicle exhaust can cause carbon monoxide to accumulate.
Traffic levels also vary significantly throughout the day and across the year. During busy periods, ventilation must respond quickly to rising CO levels. At quieter times, however, operating fans continuously at full capacity wastes a considerable amount of energy.
A traditional fixed-schedule ventilation system cannot always respond effectively to these changing conditions. The IKEA Auckland project therefore required a monitoring and control solution that could protect visitors and staff while operating the ventilation system more efficiently.
The Solution: Demand-Controlled Ventilation with Tongdy TKG-CO
Tongdy supplied the TKG-CO monitoring and control solution, designed for underground car parks, commercial buildings and other public spaces where reliable carbon monoxide monitoring is required.
Accurate CO Monitoring
The TKG-CO uses a long-life electrochemical sensor to continuously measure carbon monoxide concentrations. Different measurement ranges are available to suit specific project requirements.
Automatic Ventilation Control
The controllers provide real-time CO data to the ventilation system. When the concentration exceeds the configured threshold, the exhaust fans can be activated automatically.
Once CO levels return to an acceptable range, fan speed can be reduced, or the ventilation system can be switched off. This demand-based approach reduces unnecessary fan operation and associated electricity costs.
An optional audible alarm can also be enabled to provide an immediate on-site warning when CO concentrations become unsafe.
BAS and BMS Integration
The TKG-CO supports Modbus RTU and BACnet MS/TP communication, allowing the devices to be integrated into the store’s existing building automation or building management system.
Facility teams can centrally monitor CO levels, review operating conditions, and coordinate ventilation control through the building management platform.
Flexible Control Outputs
The controller provides 0–10 V or 4–20 mA analogue outputs, together with two relay outputs. These options allow it to connect with different types of exhaust fans, variable-speed drives, alarms and ventilation control systems.
Project Benefits: Improved Safety and Energy Efficiency
Following the deployment of the TKG-CO controllers, the IKEA Auckland store gained a more responsive and efficient approach to underground car park air quality management.
Continuous Safety Monitoring
Twenty-four-hour CO monitoring helps prevent the build-up of harmful vehicle exhaust and reduces the risk of carbon monoxide exposure. It also contributes to a safer and more comfortable environment for customers, employees and maintenance personnel.
Lower Ventilation Energy Use
Instead of running continuously at full capacity, the ventilation system operates according to actual CO concentrations. This can significantly reduce fan operating hours, electricity consumption and equipment wear.
Support for Compliant Building Operation
Continuous monitoring, alarm functions and automatic ventilation control help the car park meet local commercial building safety and indoor air quality requirements in New Zealand.
Professional Air Quality Monitoring for Global Buildings
From Beijing to Auckland, Tongdy provides professional indoor air quality monitoring and control solutions for commercial buildings worldwide.
By delivering reliable monitoring data and supporting integration with ventilation and building automation systems, Tongdy helps building owners and facility teams create safer, healthier and more energy-efficient indoor environments.
Frequently Asked Questions
Where is the TKG-CO typically used?
The TKG-CO is suitable for underground car parks, enclosed garages, commercial buildings, office buildings and other locations requiring carbon monoxide monitoring and automatic ventilation control.
Can the TKG-CO connect to a building automation system?
Yes. It supports optional Modbus RTU over RS485 or BACnet MS/TP communication for integration with BAS and BMS platforms.
What output options are available?
The controller provides a 0–10 V or 4–20 mA analogue output, together with relay outputs for fan, alarm or other control applications.
What CO measurement ranges are available?
The standard measurement range is 0–100 ppm. Optional 0–200 ppm and 0–500 ppm ranges are also available.
