Course Content
By the end of this course, you will be able to design a Tasmanian envelope that manages the moisture a cold, heating-dominated climate drives through it. Warm humid indoor air, the dew point and the cold surfaces and hidden layers where vapour condenses are worked through first, so every later decision reads as a consequence of the physics rather than a rule. The NCC 2022 condensation management provisions are then applied to wall and roof construction, with the vapour-permeable wall wrap, roof space ventilation and exhaust to outside treated as a floor to build above. Vapour control tight to the warm inside and open to the outside, continuous insulation, air tightness paired with deliberate ventilation and cold-climate glazing are assembled into one drying envelope. Buildability, heat recovery ventilation and the documentation that protects both the building and the architect close the hour, with two Tasmanian case studies showing where cold-climate condensation actually starts.

What’s Included
This course examines why a heated Tasmanian building in climate zone 7 drives moisture outward through its fabric, and where that vapour condenses on cold surfaces and inside walls and roofs. Surface and interstitial condensation are separated, with the tighter, better-insulated home shown to trap the moisture that draughty older housing used to leak away. The NCC 2022 condensation management provisions are read as design decisions, covering the vapour-permeable wall wrap, ventilated roof spaces, exhaust discharged outside and the limits of the deemed-to-satisfy floor. Vapour control on the warm side, continuous insulation, air tightness with controlled ventilation, glazing, wet areas and low-profile roofs are then assembled into an envelope that keeps surfaces warm and can dry. Two case studies, a sealed Hobart renovation and a new home wrapped in a vapour-closed membrane on the cold side, apply the same principles to the failures that most often reach a Tasmanian architect.
Why Take This CPD Session?
Understand why the vapour control layer sits toward the warm inside in a Tasmanian wall, the reverse of the tropical habit, and read every membrane, insulation and ventilation decision as a consequence of the dew point.
Apply the NCC 2022 condensation management provisions as a floor, then decide when a heavily occupied home, a sheltered damp site or a skillion roof needs a performance solution above it.
Build the documentation and site verification habits that keep a membrane on the right side and an exhaust duct out of the roof space, tested on a sealed Hobart renovation and a wall wrapped the wrong way round.
