A key focus of the design for CH2 is the indoor environment quality. In CH2 the air intake is 100 per cent filtered outside air, instead of being recycled as it is with traditional air-handling systems in most office buildings.
In addition, materials have been selected for qualities that minimise the harmful effects of off-gassing and indoor pollutants, such as Volatile Organic Compounds (VOCs).
Indoor plants have a proven role in the improvement of indoor air quality in office environments. There is at least one indoor plant per person in CH2.
CSIRO has undertaken indoor air quality tests during summer and winter conditions and in both assessments the indoor air quality in CH2 for the weeks of assessment was rated as very good. The reports are available by visiting Staff wellbeing.
