- The complex worked with Tsinghua University through the Joint Research Centre for Building Energy Efficiency and Sustainability on an indoor air quality (“IAQ”) study to establish an improvement plan, which incorporated minimising air infiltration, enhancing air purification via electric polarisation, and online IAQ monitoring via IoT sensors.
- Real-time sensors were installed to monitor IAQ data, with the monitoring system meeting WELL V2 requirements.
- In the basement arcade, IAQ improvement measures included:
- Installing new fresh air handling units with a higher volume and better purification for PM2.5 and total volatile organic compounds (“TVOCs”).
- Installing 80 air treatment units on the ceilings.
