FAQ F-00258
How can compliance with Provision of Outdoor Air be demonstrated for naturally ventilated, non-residential buildings?

For Minimum Expectations

Provision of outdoor air - non-residential buildings

Where ventilation is by natural means, the building must provide a 50% improvement of outdoor air required by AS 1668.4-2012 to each space in the regularly occupied areas under all likely weather conditions. Projects must justify how the regularly occupied areas will perform as a naturally ventilated space in these conditions. If any mechanical ventilation is present, other than ceiling fans, then the space cannot be considered naturally ventilated. 

 

For Credit Achievement

Provision of outdoor air - non-residential buildings

Where ventilation is by natural means, the building must provide a 100% improvement of outdoor air required by AS 1668.4-2012 to each space in the regularly occupied areas under all likely weather conditions. Projects must justify how the regularly occupied areas will perform as a naturally ventilated space in these conditions. If any mechanical ventilation is present, other than ceiling fans, then the space cannot be considered naturally ventilated. 

If a building achieves a Passive House certification, Credit Achievement is considered to have been met.
