Ventilation
Whether via natural or mechanical
means, Council recommends
substantially exceeding minimum
requirements for window opening
sizes and air exchange rates under
the Building Code of Australia.
In homes, the most effective
ventilation is achieved through natural
cross ventilation. The ideal layout
features openable windows located
in opposite walls, which creates a
breeze path to let in fresh air and flush
out stale air. Note that cross ventilation
can be achieved through various
façade openings, be it standard
windows, operable skylights or even
small solid doors.
In office buildings, air change
effectiveness is important to ensure
good quality air. Carbon dioxide levels
should be regularly controlled to
ensure a healthy and productive work
environment. In smaller offices, natural
ventilation is also a great way to save
energy and cater for individual’s
differing comfort needs
