In this episode of the pro clima Podcast, Steve shares his journey from living in a renovated 1860s villa in Ponsonby, Auckland, to building an off-grid Passive House in Coromandel. He recounts how the villa’s renovation revealed issues with heat retention, leading to high energy costs and discomfort. This experience, along with a desire to live more sustainably, inspired his family's move to Coromandel, where they began with minimal infrastructure, even living in a tent while constructing their new home.
\n\nSteve discusses with Simon the process of building the new passive home, emphasizing the importance of energy efficiency through careful design and the challenges of using unconventional building materials. He explains the significance of proper ventilation, airtightness, and thermal performance for a comfortable home environment and provides insights on energy modelling, cost considerations, and meeting Passive House standards. Steve also addresses the broader context of New Zealand’s housing, stressing the need for improved thermal performance and energy efficiency.
\n\nThroughout the podcast, he shares valuable lessons from his hands-on experiences and encourages others to consider sustainable building practices, whether in new constructions, smaller dwellings, or retrofitting projects.

In this episode of the pro clima Podcast, Simon Cator and Jon Davies speak to Building and Construction Minister Chris Penk.
\n\nThe discussion revolves around the Minister’s desire to build “Simply, Cheaply and Quickly” - the recent controversial media furore regarding the government's signal to roll back the H1 insulation standards and other building and construction-related issues.
\n\nThe discussion also touches on easing the regulations for granny flats, developing well-qualified construction workers and revising regulations to maintain building standards.
Special Guests: Chris Penk and Jon Davies.

"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."
\n\nIn 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.
\n\nSharon 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.

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."
\n\nIn 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.

"We moved into a brand new house in Taupo, it was double-glazed and looked good, but it was blimmin' cold. I couldn’t understand why people would put up with it. Because of this environment, we decided we wanted to live in a more comfortable house."
\n\nIn this episode of the pro clima Podcast, Simon Cator interviews Kim Feldborg, a builder from Denmark who moved to New Zealand in 2007. Shocked by the cold temperatures in his rental home, Kim decided to design and build a Passive House, which he and his family have been living in for over ten years now. Kim explains the differences in home heating between Denmark and NZ, noting that Danish homes typically have central heating systems, whereas Kiwi homes often lack adequate heating. He shares his journey in designing his own Passive House, including sourcing materials and ensuring airtightness. Kim highlights the energy efficiency of the house, which maintains a constant temperature with minimal heating costs. He also addresses common misconceptions about airtight homes, emphasizes the benefits of ventilation systems and discusses the new H1 compliance.
