During the discussion, he shares some of the main challenges he faces, particularly misconceptions around the cost of Passive House design. He highlights the need to educate clients and consultants on the numerous benefits of Passive House design, while addressing common misconceptions, such as the belief that Passive Houses are prohibitively expensive or that windows can't be opened.

Simon and Vlada also touch on the future of Smart Home Technology integration with Passive House design. Vlada sees great potential in using smart controls—like external shutters and roll blinds—to manage solar gains and air temperature, improving both performance and comfort in Passive Houses.

Throughout the podcast, Vlada emphasizes the critical balance between theoretical knowledge and practical application in house design, stressing the importance of education and raising industry standards in construction.

“It's easy to explain why Passive House is champion, because we know that it's arguably the highest possible standard in energy efficiency.”

Special Guest: Vlada Acimovic.

Steve 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.

Throughout 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 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.

Special Guest: Sharon Robinson.

In 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.

In this episode of pro clima podcast, Darryl shares insights from his experience with energy-efficient building projects, including the Piha EnerPHit renovation and the Legacy House. He talks about the importance of improving the performance of existing homes in New Zealand, proposing standardized systems to facilitate retrofitting. Darryl highlights the challenges of addressing issues like condensation moisture management and airtightness in the Building Code. He emphasizes the need for a holistic approach to building design, advocating for increased industry skills and the adoption of modelling approaches to ensure overall performance of buildings meets high standard and comfort.
