Australian standards for bathroom windows

Therefore, irrespective of whether an exhaust fan is installed, if the room in question has a window installed in accordance with the provisions of sub-clause a then the ventilation requirements for the room complies with the BCA. If the room has ventilation borrowed from an adjoining room in accordance with sub-clause b it also complies with the BCA. If an exhaust fan is installed, it only needs to comply with sub-clause c if it is the only source of ventilation to the room.

The regulations require a fan capable of a minimum extraction capacity of 25 litres per second when installed. The regulations require a fan capable of a minimum extraction capacity of 50 litres per second when installed. The regulations require a fan capable of a minimum extraction capacity of 20 litres per second when installed.

The area itself may be defined just as one particular room, or a combined set of adjoining spaces. Also, in a room where there is no ceiling fan, the BCA states that you must achieve effective cross ventilation.

Question: How do I know that the builder has installed windows and doors in my home that comply with the Building Code of Australia? Answer: All windows and doors for homes must have a performance label which confirms they are certified to comply with Australian Standard AS Across Australia, the energy efficiency bar is being lifted with the rise from a 5 to 6-star energy rating mandatory for all new residential buildings. While the commencement date of this legislation differs from state to state Victoria, Queensland and the ACT have already introduced the code , at some point in the near future all Australian homes will need to meet this minimum level of energy efficiency.

Energy ratings apply to the whole building - not just individual elements or materials. The achievability of star ratings is largely dependent on the climate experienced by the home. For example, the amount of energy lost from a 6-star rated home in Brisbane will be different to less than that for a home in Canberra. Generally speaking, compared to other materials used in the building, windows are poor heat insulators and let a lot of radiant heat from the sun into a home.

Therefore windows have a big impact on the star rating that can be achieved by a home.
