Maximise natural ventilation where windows require fall prevention or extra strength.
WINDOW REPLACEMENT IN APARTMENTS
Fall Prevention Standards
For new buildings, fall prevention measures are only required on some windows. Please visit the Fall Prevention Compliance page for more information.
However, in New South Wales all Strata buildings must be fitted with devices that enable windows two metres above ground floor to be in compliance by 13 March 2018.
Read the NSW Fair Trading Window Safety Device Requirements here.
For existing apartment buildings, the obvious choice is a simple key locking device. Although this may be the cheapest option, it will severely restrict the airflow into the room. The Building Code of Australia Natural Ventilation and Energy Efficiency provisions do allow the use of such a restriction, as the openable area is measured on the sash size not the area that actually opens.
However, the reality for the occupant may be very different. A typical sized bedroom with a standard 1200mm high and 1800mm wide sliding window and a key locking restriction could in reality have as little as 1.2% ventilation to floor area, not the greater than 5-10% that is typically required.
Natural Ventilation to Floor Area
A typical keylocked sliding window may have an opening area of 0.15m2 which provides 1.2% ventilation as a % of floor area.
How much ventilation as a % of floor area?
Please refer to the graph below which shows the % of ventilation to floor area a keylocked sliding window has in comparison to the % required by the Building Code for a new building.
Lack of natural ventilation can lead to unhealthy air quality, excessive air conditioning costs, potential mould problems and discomfort for unit owners or tenants. This option may also lead to end users unlocking the window and negating the fall prevention rule.
