- Members of the unit work on both
the theoretical and the applied aspects
of design computation.
- On the theoretical side, we work on
shape grammar and its uses in design
process and historical analysis.
- Towards the applied end, we work
on computation fluid dynamics, airflow
simulation, urban visual sustainability,
daylighting, and urban noise.
- Demonstration Projects of CS Unit
are:-
Isolation Patient Ward Design
Reconfigure existing building as isolated patient
wards to cater for epidemic outbreak
- A joint project of the Department of Architecture
and the Faculty of Medicine, CUHK (Recipient of
the First Honored Award in the 8th Challenge Cup
National Competition of Scientific and Technological
Projects 2003)
- The hospital is designed as a series of basic
modules that could be flexibly arranged to adapt
to different environments. Applying computational
fluid dynamic simulations, we have designed the
air handling system to maintain a clear distribution
pattern in the patient ward, so that fresh air passes
from the inlets first to the attending medical staff,
then to the patients, and finally leaves the ward
through the exhaust outlets. We have also applied
multiphase time dependent simulation to assess
the distribution of water droplets emitted from the
patients. Results indicate that these droplets will
not disperse widely, and could be extracted within
a short time.
- With its rapid assembly, carefully planned air
handling, and economical cost, this hospital could
provide fast and effective isolation of infected
patients to quickly contain a future outbreak of
infectious disease.
Architectural Studies of Air Flow at Amoy Gardens, Kowloon Bay,
Hong Kong, and its Possible Relevance to the Spread of SARS
- The Architecture Department of The Chinese University of Hong
Kong has conducted a detailed computational fluid dynamics
(CFD) study investigating the entire Amoy Garden complex. It was
found that the placement of Blocks E and F, relative to each other
and relative to the prevailing wind direction leads to a “wind curtain”
effect, sealing off the reentrant area (light well), in which the
horizontal air–flow becomes nearly stagnant. Thus, any droplets
laden with viruses that may be released into the reentrant area
will have a high tendency to remain in the area, and therefore to
spread vertically and contaminate other floors.
