ABBOTSFORD SCOUT HALL

The brief: Design a Scout Hall for Scouts Australia with a timber theme (at one of their existing locations) that would incorporate a Basketball court and other associated services required of scouts. The Abbotsford site was chosen due to its beautiful surroundings and proximity to the wharf inspiring a water-side building with a deck.

The final model was displayed in the University of Sydney Hearth foyer for 6 months in 2013.

AXONOMETRIC
       
     
AXONOMETRIC

The Roof design focussed on using timber elements such as Kielsteg - a German engineered wood product with long span. This allowed us to span the necessary distance for a basketball court with only a 600mm depth using only timber. The structure is a post-and-beam style construction with frames at 1200mm apart. The cavity houses a strip of mottled ETFE skylight for diffused lighting.

HELIODON TESTING
       
     
HELIODON TESTING

The effectiveness of the roof overhang and translucent skylight panels were tested using a heliodon at 3 hour intervals during the summer-winter solstices and equinox periods of the year to provide even lighting thoughout the hall, reducing glare whilst encouraging natural heating during winter and efficient relief during summer.

WIND TUNNEL TESTING
       
     
WIND TUNNEL TESTING

The design was wind-tunnel tested to ensure the effectiveness of the natural ventilation strategy employed. The natural cooling of the hall is created by utilising the sea-breeze to push and suck out the air within the hall. The Stack effect applies Bernoulli's principle, which creates a high-pressure zone within the hall by adjusting the opening sizes to the optimal ratio.

The windows remain adjustable to allow for flexibility during colder months.
