Introduction to Taikoo Place’s New IAQ Monitoring System

Background

Nowadays, people spend over 90% of their time indoors in Hong Kong. Inhalation of indoor air pollutants can lead to a variety of negative short and long-term health and well-being conditions that can vary in severity.

With the implementation of our central air-conditioning system consisting of a high-quality filtration system and fresh air supply, we aim to deliver a high level of Indoor Air Quality (IAQ) within our premises in order to optimise conditions for productivity, well-being and health.

Therefore, we have introduced an IAQ continuous monitoring system consisting of smart online IAQ sensors to monitor our IAQ on a 24/7 basis and enabling occupants to read the IAQ in real time, wherever they may be.

System reference

Our smart IAQ monitoring system is referenced from the established and world-known WELL Building Standard™ version 2. The WELL Building Standard takes a holistic approach to health in the built environment, addressing behavior, operations and design. It is a performance-based system for measuring, certifying, and monitoring features of the built environment that may impact human health and well-being.

IAQ parameters and why these parameters?

8 key parameters have been selected to monitor in our buildings, namely
  • Indoor Temperature (Unit: oC) details
  • Indoor Relative Humidity (Unit: %) details
  • Carbon Dioxide (CO2, Unit: ppm) details
  • Carbon Monoxide (CO, Unit: ppm) details
  • Total Volatile Organic Compounds (TVOC, Unit: µg/m3) details
  • Respirable and Fine Suspended Particles (PM2.5, Unit: µg/m3) details
  • Respirable and Fine Suspended Particles (PM10, Unit: µg/m3) details
  • Ozone (O3, Unit: ppb) details

The 8 parameters have been identified as the most potentially hazardous to health and are the most prevalent in Hong Kong.

IAQ Classifications

The IAQ is defined in two classifications:
  • Great Quality - represents a good IAQ protecting building users including the young and the aged
  • Prime Quality - represents a best in class IAQ for a high-end and healthy environment

These objectives are comparable to the international health-based air quality standards which are intended to protect a more diverse target population including the young and the aged.

In case the IAQ is out of the above-mentioned classifications, prolonged exposure to those pollutants may cause health issues.

Sources of pollutants and impact to humans

  • Dust, exhaust from vehicles, photocopiers, printers and fax machines, emissions from furniture, adhesives and paints, and exhalation from occupants are the main sources of these 8 pollutants
  • Less severe symptoms of short-term exposure can include headaches, dry throat, eye irritation or runny nose, while more severe health outcomes can include asthma attacks, hypersensitivity pneumonitis, heart diseases or cancer.
