Your Guide to Condensation and the National Construction Code

Two-day workshop

Day one: Introduction to Condensation

The regulations around condensation management and the National Construction Code (NCC) are evolving rapidly. With changes introduced in NCC 2019, updated in NCC 2022, and further amendments proposed for NCC 2025, staying informed is critical for industry professionals.

Key topics:

• Understanding the five main factors contributing to condensation and mould:
  • airtightness
  • vapour load
  • vapour permeability
  • thermal bridging
  • dew point shift
• Practical strategies to minimise condensation and mould risk in modern buildings
• The impact of increasing energy efficiency on condensation issues
• Real-world case studies demonstrating best practices in building design

Day two: NCC 2022 Condensation Management Provisions

Since 2019, the NCC has significantly increased requirements to manage building condensation. This workshop focuses on the real-world implications of these changes for designers, certifiers, builders, and tradespeople.

Key Topics:

• Understanding NCC Housing Provisions Section 10.8.3:
  • ventilation of bathrooms, kitchens and laundries
  • wall construction
