typical infiltration rates for houses
Studies on air infiltration rates in Australia have been few. One study measured 'natural' infiltration rates in unoccupied houses in Melbourne and found that background infiltration rates were 0.33 air exchanges per hour (ACH) (Biggs et. al.1987).ata.

Residence Districts: R5 - R5 infill - R5A - R5B - R5D. R5 districts allow a variety of housing at a higher density than permitted in R3-2 and R4 districts. The floor area ratio (FAR)of 1.25 typically produces three-and four-story attached houses and small apartment houses.
