NCC22 - Ventilation & Condensation sections, and Airtightness.

29/05/2023 | 02:00 PM - 03:00 PM AEST

 

Event overview

Moisture, water vapour, conditioned spaces, ventilation and mould. Whether you are in Darwin or Hobart getting the mix of envelope elements right is needed to ensure that the building interiors are economical to condition and the built fabric remains durable. 
This activity will explore aspects of ventilation air-tightness and condensation within NCC 2022. It will include some thoughts re ‘code’ and ‘better-than-code’ and some explainers re water vapour diffusion and ACR/AEH/ACH and more.    

Learning Outcomes:

  • An understanding of the principles of water vapour diffusion.
  • An understanding of the conditions that promote condensation.
  • An understanding of the conditions that promote mould growth.
  • The understanding of some key design and construction principles to provide high-performance building envelopes that do not support moisture accumulation or mould growth.   
 

PRESENTER:

Dr. Mark Dewsbury  

Dr Dewsbury has been involved in the sustainable design of commercial and residential buildings in the public and private sectors for more than 30 years. He is currently a Senior Lecturer and director of the Tasmania Architectural Science Laboratory (TASL), within Architecture & Design, at the University of Tasmania. His research focuses on methods to inform design and to improve the construction, durability, thermal performance, indoor environmental qualities, moisture and mould growth risks within buildings. As a member of the NatHERS Technical Advisory Committee and the ABCB’s Condensation technical working group, his research provides input for the Nationwide House Energy Rating Scheme, CHENATH, the AccuRate building simulation programs and the condensation requirements within the national building regulations. Mark has undertaken contract research for a broad range of industry and government partners including the CSIRO, State and Federal government agencies, and Forest and Wood Products Australia. He is also a principle partner at Carawah, which specialises low energy dwellings.
