Condensation doesn’t just happen by chance—it’s predictable. Using tools like WUFI Analysis, we can simulate how heat and moisture interact with your building's materials, providing you with the insights needed to prevent future moisture problems. Whether you're constructing a new home or renovating, this analysis can predict where condensation will occur, allowing you to make informed decisions about materials, insulation, and ventilation. By acting now, you can design a home that stays dry and mould-free, ensuring long-term comfort and health for its occupants.

Integrating building science into the New Zealand Building Code presents unique challenges, particularly when balancing heat protection, moisture control, and energy efficiency. In this article, we explore how heat flow impacts various building code clauses, including H1 (Energy Efficiency) and G4 (Ventilation), and highlight the often-overlooked role of thermal bridges. As buildings become more airtight due to improved insulation, managing internal moisture becomes crucial, yet current regulations like Clause E3 fall short in addressing hidden condensation risks. We discuss potential solutions, including international standards that offer better guidance for moisture control and thermal bridging.
