The webinar recording will be available at HKGBC CPD Online Training Portal (https://onlinecpdtraining.hkgbc.org.hk/) later after the event.

This webinar is organised by the Hong Kong Green Building Council.

Part 1 - Let’s Clear the Air

In this webinar, representative from Airguard Industries (Hong Kong) Limited will cover Indoor Air Quality (IAQ) monitoring and management using state-of-the-art technologies. The speaker will cover these two topics: 

• The tangible effects of IAQ regulations in indoor environments; 
• The application of technology and data-driven methods to improve IAQ.    

The speaker will first examine the government’s IAQ regulations and introduce the problem of enforcing such standards. This will be followed by a few case studies and data visualisations of multiple Grade-A buildings and public indoor areas that have proven to display elevated CO2 and bacterial levels due to poor IAQ management. 

AirGuard will then provide some applications for using IoT sensors, 5G networks, big data analytics, early AI warning systems and an innovative air sanitising liquid cum active filtration system for the effective IAQ management of buildings. 

Part 2 - Non-conventional Ventilation System for Restaurants to Avoid Spread of COVID-19

In a typical ventilation system using Air Handling Units (AHUs) in a large restaurant, the supply air flows from the ceiling level through an array of evenly distributed air grilles over the occupied area. Meanwhile the return air is extracted at the ceiling level from the side edges of the occupied zone. This overhead ventilation system forces air at high velocities to achieve a complete mixing of air to maintain the desired temperature in the occupied zone. Exhaled air from patrons at each table is mixed with the incoming air and spreads horizontally to neighbouring tables. In the event of an index case at one table, diners at neighbouring tables within short distances are likely to be infected. Furthermore, the exhaled air from the index case may be extracted through the return air grilles and be carried to tables further away through the AHUs and supply air ducts. 

In this talk, Ir Dr CHAN Hon-fai proposes a non-conventional air ventilation system to avoid the lateral spread and long distance spread of COVID-19 virus through the ventilation system.
