The Brief
Square needed a comprehensive indoor air quality monitoring network across the entire building, with real-time visibility into conditions in each room and deployable purification solutions to address air quality where the ventilation system alone was insufficient. The monitoring infrastructure also needed to serve as the foundation for a future smart ventilation integration.
What We Did
Airscan designed and implemented a building-wide monitoring network, with devices installed across each room to measure CO2 and PM2.5 concentrations alongside comfort parameters — temperature and humidity — feeding continuously into Airscan’s cloud platform. Working alongside partners VFA Solutions and Genano, Airscan also deployed mobile air purification units throughout the facility to supplement the ventilation system in high-demand spaces. The monitoring network forms the core of Square’s air quality management plan, providing the building management team with the real-time data needed to make informed operational decisions.
How It Works
Each device in the network transmits pollutant and comfort data to the cloud in real time, giving building management a live view of conditions across every room simultaneously. CO2 is the primary indicator of ventilation adequacy — in a convention centre where room occupancy can swing dramatically between events, that kind of continuous visibility matters. The mobile purification units provide a flexible, deployable response where ventilation alone is not sufficient to maintain air quality under peak load. In the next phase of the project, Airscan’s smart ventilation control system will connect the sensor data directly to ventilation management, allowing the building to respond dynamically to occupancy conditions and reduce energy consumption in the process.
Outcomes
The combination of real-time monitoring and mobile purification enabled Square to achieve the COVID-safe zone label, awarded by test and inspection body Vinçotte, part of Kiwa group — independent validation that the air quality measures in place met a recognised standard. The monitoring network continues to support regulatory compliance and provides the operational data needed to manage health and comfort across a building of this scale. The smart ventilation integration, which will use that same data to optimise energy consumption and reduce the building’s carbon footprint, is in progress as the next phase of the project.
