Cold Zone

Cold Zone

This region corresponds to NCC/BCA Climate Zones 7 and 8. It contains only two capital cities – Canberra and Hobart. The direction of vapour drive is outward.

Condensation Risk in Walls – Hygrothermal Analysis

Interpreting condensation risk

When the temperature is lower than the dew point condensation will form. When the Temperature profile and Dew Point lines intersect this is the location point of the condensation in the wall.
