Concrete was specified for the structural frame so this
could act as exposed thermal mass to help with energy efficiency.
Large areas of soffit and all columns were to be exposed so a detailed
specification was produced to ensure that the highest quality finish
was achieved alongside restrictions of number of blowholes and
surface variations. On site, a clear Kiem wash was applied to the
concrete throughout the building to help provide a consistent finish.
Early design coordination was required to confirm lighting positions
as these were cast into the slab, to be fed from the raised access
floor above.
Acoustics are one of the most crucial factors to consider when
designing a library. Two large atria and perimeter study spaces
required treatment to ensure the acoustic criteria was met. The
feature gold staircase in the centre of the building acts as a large
acoustic baffle, with insulated metal perforated panels wrapped
around its structure, alongside insulated panels that line the
perimeter of the slab edges in the atria. Suspended metal acoustic
baffles are located above the perimeter study spaces to ensure
sound doesn’t break out into the atria. Other study spaces vary in
function from individual study, group workspaces and silent study
spaces, so these are treated locally with a combination suspended
baffles and acoustic ceilings, to help provide comfortable spaces for
students to work.
