Episode 7: Jon Davies

Pro Clima NZ Ltd — Tue, 16 Jul 2024 16:00:00 +1200

"I hope we'll see a change in the outcome for renovation work which has energy modelling and predicted energy demand for that building - for any building - in play during the design process; and then just put some minimums around that."

In this podcast, Jon discusses his transition from teaching to the building industry where tangible results were more easily visible. He talks about a home renovation project, emphasizing the importance of creating a comfortable living environment by addressing common issues like drafts and poor insulation. Jon describes his Masters thesis - the use of Parka Wrap - retrofitting insulation onto existing walls - designed to improve airtightness and contribute to a more controlled indoor environment and energy efficiency in buildings.

Jon advocates for continuous improvement and innovation in building practices. By staying updated with the latest technologies and methods, builders can enhance the quality and efficiency of their constructions. This is particularly important for the retrofit challenge, aimed at improving the performance of existing buildings to enhance the health of their occupants.

Episode 6: Sharon Robinson

Pro Clima NZ Ltd — Tue, 02 Jul 2024 09:00:00 +1200

"Ask yourself, what is your house going to be worth in 2030. A certified Passive House is on the operating levels, energy-wise, of where we're going in 2030. So do you consider your house an investment? I think we put more consideration into the performance of the cars that we buy than we put into the houses that we are creating, and our homes are the largest financial investment that we make in our lives."

In this podcast, Sharon advises homeowners to research the Passive House principles via the Passive House Institute of New Zealand (PHINZ) website, focusing on insulation, airtightness, quality windows, ventilation, and thermal bridging. She emphasizes the importance of discussing energy efficiency and comfort with building professionals early in the design process. Building high-performance homes from the start is more efficient than upgrading conventional homes later, and smaller, better-performing homes can also be more efficient.

Sharon and Simon also discuss misconceptions about building codes often leading to minimal standards being mistaken for optimal performance; energy modelling and data-driven design are essential for achieving true efficiency and comfort, with professional designers offering long-term savings despite higher initial costs.

Episode 5: John Straube

Pro Clima NZ Ltd — Tue, 18 Jun 2024 12:45:00 +1200

Dr. Straube explains the importance of the critical elements of the building structure, balancing insulation values with good airtightness levels and high-performance windows: "It's a rule of physics that you need to be able to match those three components of typical houses to get the value out of each one of those components."

In this episode of the pro clima Podcast, John Straube emphasizes the importance of balancing components such as insulation, airtightness, windows and ventilation in building design to achieve optimal energy efficiency and indoor air quality. He explains that airtightness is often misunderstood but is crucial for maintaining a healthy indoor environment. Dr. Straube also discusses the principles of rainscreen design, considering the cladding, drainage, and water-resistant barriers, all tailored to local climates and building codes.
