Occupancy issues in sports stadia andleisure complexes becoming paramount
Increasingly common to use CFD in the
design process to assess:- natural ventilation (comfort)
mechanical ventilation
pitch ventilation exhaust discharge
fire safety

Located within the Melbourne Docklandsurban re-development precinct
Designed and built within 2 years
Used for AFL/soccer/rugbycricket and concert events
Seating capacity of 52,000
including a movable lowerstand tier of 12,500 seats
A 167m by 132m retractable pitch roof
(can open & close in under 10 minutes)

When roof is closed it becomes a fullyenclosed all weather indoor facility
Occupancy comfort and life
safety needs considerationOther similar stadia normally
include mechanical ventilation
Concerns about large capital costs andongoing energy consumption led to a
design study for justifying an effective
passive (natural) ventilation solution

Location & spacing of roof vents optimisedArchitectural design of roof vents and
facade openings promote air movement
which enhances occupant comfort for awide range of environmental conditions
Temperature rises around bowl arena not
deemed excessive (within 5o
C) assumingthe patrons are suitably attired consistent
for a naturally ventilated facility
Life safety tenability criterion also satisfied

Recently redeveloped for increasedseating capacity
Designed to be capable in the future of
incorporating a retractable pitch roofCFD modelling was conducted to
determine natural ventilation openings
necessary to provide spectator comfortScenarios simulated for different
environmental conditions for both an
open stadium and with a pitch roof

Venue is to be upgraded in readiness for2006 Commonwealth Games
Outdoor pool arena is being proposed
with lightweight roof and open sidesFor energy impost and
sustainable development
considerations naturalventilation is postulated

Ventilation within an indoor pool needs toensure sufficient fresh air requirements
Necessary for removal of water vapour (RH
control) and chemical vapoursDifferent mechanical
ventilation systems
configurations wereanalysed with CFD
Establish air movement distribution and
show undesirable stagnant flow regions

Performance based approach used tosatisfy BCA fire design requirements
CFD modelling was conducted to ensure
indefinite tenability conditions aremaintained within concourse/vomitories
Provide assistance in optimising the
smoke extraction system in terms of sizeand capacity
Consequently gives indication of expected
capital cost outlay of mechanical systems

Project case studies have shown the use ofCFD as an important part of the engineering
design process of sports stadia/arenas
Issues relating to ventilation, occupancycomfort and life safety can be addressed
Facilitates sustainable design technology
solutions by avoiding/limiting mechanical
ventilation energy usage as far as possible
Can be promoted as worlds best practice
and used as a benchmark for stadia design
