into the process,” says Jaco Kemp who leads the
sustainability team at Arup.
“Compared to No. 2 Silo, we tried to increase
energy efficiency in the HVAC and the façade
design. The design concept for No. 3 Silo and
No. 4 Silo consists of three distinct towers,
unified by the lightweight glassy vertical
transportation cores. Dividing the buildings into
three towers increases the surface area of the
façade and allows for maximum views, correct
orientation, influx of light and ventilation,”
Kemp adds.
No 3 & 4 Silos
Arup designed a series of different façade types
for the multi-unit residential and gym buildings,
with a particular focus on reducing the heat
loads through solar gain in order to limit energy
usage. “The client required stringent weather
performance, acoustic infiltration limits and
excellent overall product quality due to the project’s
location in a harsh seaside working harbour and
the image of the development”, explained Tessa
Brunette, Arup façade designer on the project.
No. 3 and No. 4 Silo are currently in pursuit of a
Green Star Custom Mixed-Use rating.
