St. Stephens College, a leading private school on the Gold Coast in Queensland, had a significant summer overheating problem in their large basketball hall.
Four large bladed fans had been specified as a cooling option, but St. Stephens College approached Airius to see if they could provide a more aesthetic, simple to install and cost effective solution to cooling via air movement in the hall. The specified Airius solution satisfied the customer on all counts.
School and community sports centres are large spaces and in
the Australian climate often have issues with overheating in summer.
Current solutions are limited to:
The use of air movement for cooling by moving the air across
the skin and causing evaporation has been used for centuries in all sorts of
tropical and temperate climates. It is a
cost-effective solution to the overheating problem.
In 2015, St. Stephen’s College’s Director of Sport, Rob
Seib, approached Airius to provide a proposal to supply an Airius cooling
solution as an alternative to large bladed fans.
The two basketball courts were in a relatively new building
with high roofs around 10 metres high and around 1400 sq metres in size.
Located in a sub-tropical climate, high summer and moderate winter temperatures
combined with high humidity are typical for the area.
The building design has limited capacity for cross flow
ventilation and suffered from severe overheating in spring and summer. The
building is used for both sports and classes and the overheating impacted
negatively on both sports performance and learning outcomes.
Airius supplied 12 x Model 60 Airius Standard Series units
with two 5 Amp speed controllers, for an installed cost of around 15% cheaper
and with greater floor coverage than the alternative large bladed fans.
As a bonus the units are very quiet and are adjustable in
any direction to enable the customer to direct the air flow to where it may be
At 10 metres high these unobtrusive and quiet units provide
a large amount of air flow all across the space. Full speed control capability
is offered in five steps from 0-100%.
The improvement in comfort inside the space was instant and the customer indicated that even in the warmest days in the Gold Coast summer the air movement offers cooling and has made the space much more comfortable and usable.
