Reading G2
Why the document says what it says: its COMMENTs, what it leaves unsaid about a laundry people walk through, and where it meets E3 and G3. It does not print.
Laundering facilities
- Why the cylinder1.0.2 COMMENT
- The COMMENT says it is so a bucket can be filled or washed in the tub.
- Another route for the tub1.0.3
- A laundry tub that complies with AS/NZS 1229 is acceptable, and more than meets 1.0.2.
Service connections
- Other clauses1.1.3 COMMENT
- The COMMENT names G9 Electricity, G12 Water supplies and G13 Foul water as also bearing on laundering facilities.
- The laundry floorE3/AS1 3.1.1
- A laundry tub is a sanitary fixture and a washing machine a sanitary appliance to E3/AS1, which asks for an impervious floor in the laundry. The E3 tool reads it.
Minimum space
- Bigger machines1.2.2 COMMENT
- The COMMENT says the machine's space allows for a range of popular machines, and asks designers to check current models and make the space bigger where they need it.
- A laundry people walk through1.2.1, G3/AS1 1.5.1
- G3/AS1 keeps a kitchen's clear space off every access route. G2/AS1 has no such sentence, so it does not say whether the clear floor in front of a tub or washing machine may also be the way through, as it is in a laundry that leads to the back door.
- Whose laundries must be accessibleClause G2.3.4, limits on application
- The Clause asks for accessible laundry facilities only in camping grounds. 1.2.2 is how to provide them wherever they are intended.
Number of facilities
- Which buildingsClause G2.2, limits on application
- The Clause asks for laundering facilities in five uses only: Housing, work camps, camping grounds, early childhood centres and old people's homes.
