They discuss the role Home Style Green plays in educating and assisting New Zealanders in designing and building more sustainably, along with addressing carbon targets and reporting requirements. Throughout the podcast, Matthew shares insights about the assumptions surrounding new builds meeting healthy living standards and explains the differences between the three methods for calculating energy or insulation values for homes: the modeling method, the schedule method, and the calculation method. He also examines the efficiency of the Building Code and highlights the significant progress still needed in this area.

They discuss the early development of WUFI® software and how he helped in the early stages of the development process, working alongside Hartwig Künzel. He touches on the differences between WUFI® modelling and the Glaser method, and how the Glaser method can often lead to overestimation of moisture issues. “What people don't know is how many times we discovered measurement errors because we figured out that. I mean, at some point we've seen that the measurement and the simulation doesn't work out well.” Special Guest: Manfred Kehrer. wufi, airtightness, vapour permeability, construction new zealand, hygrothermal modeling, building performance Join Simon Cator and Manfred Kehrer as they discuss Manfred's upbringing in Bavaria, his interest in building science and, how he ended up working at the Fraunhofer Institute.

Hartwig dives into the critical role of understanding vapour permeability in construction, highlighting the creation and impact of the WUFI® model. He explains both the significance and complexities of working with WUFI®, along with the challenges that can arise in its calculation. Reflecting on earlier methods of hygrothermal modelling, Hartwig discusses their limitations. Now at the forefront of construction modelling, Hartwig leads efforts in developing and refining tools to measure risks like mould and rot, and is currently advancing in post-processing models to drive even greater accuracy in building science. “Vapour permeability is probably the most important parameter when it comes to hygrothermal simulations. The good thing about that is that is mostly pretty well known.” Special Guest: Hartwig Künzel. wufi, airtightness, vapour permeability, building performance, construction new zealand, hygrothermal modeling In this episode of the pro clima Podcast, Simon sits down with Hartwig Künzel, who shares his journey with Fraunhofer—from accompanying his father at the test fields as a child, through his studies in chemical engineering, to his pivotal role today at the Institute.
