CPD Webinar - Revisiting Domestic Ventilation Provisions in Light of the Pandemic and Use of Innovative Coating to Achieve Hygienic and Dust-free Air Ducts

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.

The fifth wave of COVID-19 has revealed the strong air transmission capability of the mutating virus. This CPD webinar will focus on the topic of building ventilation and consists of the following two parts: 

Part I - Ir Dr Eddy LAU of HKGBC will discuss the ventilation provisions in residential buildings. The current building regulations for Hong Kong were established in 1950s to 1970s. There are also practice notes issued some 20 years ago. With the stronger transmission capability of the virus and technological advances, how should we change our design practices to suit? This talk will attempt to answer the following questions:

- How to reduce the risks of horizontal and vertical spread of the disease in residential buildings?

- What improvement could be introduced into the Building Regulations for dealing with vent pipes for water closets?

- How to reduce mould growth and visible condensation in communal areas?

Part II – With many high-rise complex buildings, central air-conditioning systems have a major role to play in Hong Kong.  Unfortunately, many air ducts are installed in hard-to-reach locations and once installed, they might never get cleaned. Dust, mildew and microbes will accumulate in the air ducts and affect the health of the occupants. Mr Eric WONG of Wo Lee Green Solutions will introduce an innovative coating that prevents dust aggregation in HVAC air ducts and inhibits the growth of bacteria, mould and mildew.  

The coating was developed in collaboration with NAMI – a subsidiary of HKUST. NAMI is designated by the Innovation and Technology Commission as an R&D Centre for nanotechnology and advanced materials. With unique formulation and nanotechnology, the coating has been successfully applied to quite a number of projects in Hong Kong including government office buildings, wet market building, elderly flats and public mortuary.
