Lighting
No. 1 Silo has been designed with efficient
and environmental lighting in mind. Firstly, all
fluorescent fittings have high frequency ballasts
(which are more energy efficient) and highly
efficient fittings have been selected. In addition,
an intelligent individual addressable lighting
system, fitted with appropriate sensors, ensures
that lights are on only when they need to be and
at the right light levels.
Lastly, care has been taken to ensure that no
night time lighting is directed towards the night
sky in order to reduce night light pollution,
which is detrimental to fauna and flora that are
sensitive to it.
No. 1 Silo also promotes the use of
sustainable transport - not only is it located in
close proximity to a MyCiti bus stop, but the
building design includes a secure bike lock
up facility, with lockers and showers, for those
cycling to work.
Materials
From a materials perspective, the building
has been constructed using 60% less cement
when compared to a building built according
to business as usual. Further to this, the
project has supported the use of FSC certified
timber, demonstrating that timber has been
procured from environmentally sustainable and
ethical sources.
The construction process has been
underpinned by internationally recognised
environmental management standards, ensuring
that more than 70% of all waste generated
on site is recycled. An innovative feature of
the construction site was the use of green
hoarding - approximately one third of the sites
