Home Style Green - Sustainable Design and Building
This week I attended a BRANZ seminar titled 'Building for our changing climate'. Tāmaki Makaurau Auckland was the last stop on the BRANZ seminar tour of the country and it's encouraging to think that rooms of designers, builders, product suppliers, building officials and others, were interested enough in this topic to take four hours out of their week. A key takeaway is that we're not prepared. We're already handicapped by having insufficient standards in our building code to deal with our current climate. With the forecast being 'warmer and wetter', the situation is set to get worse....

info_outline Build Aotearoa 8: Cool by Design with Siân TaylorHome Style Green - Sustainable Design and Building
Many people might be surprised to know that the New Zealand Building Code does not require any consideration of overheating in homes. The energy efficiency requirements in our code are based only on the ability of buildings to keep warm without excessive heat loss. There is nothing to prevent homes from being designed with large areas of unshaded north or west-facing glass. Siân Taylor is an Architect and Passive House Designer based in Queenstown. She has experience creating homes that are designed to perform well all year round, in some of the most challenging and spectacular locations. ...
info_outline Build Aotearoa: Changing the Window Industry with Benjy SimmonsHome Style Green - Sustainable Design and Building
Stärke has been in the window industry in New Zealand since the 80s. They were at the forefront of supplying aluminium frames to the building industry but have recently made some big changes. With a focus on building performance, Benjy Simmons describes the new direction of Stärke as a 'once-in-fifty-year' change. While the company has a long legacy, they've experienced rapid change over the last few years. Benjy credits some of the openness to change to him being from outside the industry. He's come in with a different perspective. "We're beginning to see ourselves as a building...
info_outline Build Aotearoa 6: Framology with Pete HammondHome Style Green - Sustainable Design and Building
More is not always better, especially regarding the amount of timber in the frame of a house. The more timber there is, the less space there is for insulation. The way this is measured is called timber fraction. Most homes in Aotearoa are designed using the assumption that timber will make up around 14% - 18% of the area in a wall. A found that in reality, the average timber fraction is closer to 40%. This means there is considerably less space available for insulation. Unfortunately, this is not always picked up during the consenting or pre-lining inspection process. H1 Energy Efficiency...
info_outline Build Aotearoa: 5 Building Science with Denise MartinHome Style Green - Sustainable Design and Building
Denise Martin has been involved with many of Aotearoa's Passive House projects. As one of the most experienced blower door testers in the country, she's been involved with verifying a range of residential and commercial buildings both in New Zealand and Australia. I caught up with Denise to chat about how she got into building science in the first place and some of the challenges and opportunities facing the building sector in New Zealand. We also discuss the building code, energy modelling, thermal performance and air tightness. If you don't already, I highly recommend following Denise...
info_outline Build Aotearoa 4: Quality and QuantityHome Style Green - Sustainable Design and Building
I found it confronting guest this past week as she described the experiences of staying in motel emergency accommodation with a young daughter. From my relative privilege (of choosing the right parents and having things turn out ok for me so far), I find it hard to imagine being in this situation. But it's the reality for nearly 6,500 people across Aotearoa, half of whom are children. This is an emergency, and the problem is complex. The solution will require more than simply building more houses because the underlying issues are more complex than that. Related to this is a proposal...

Last week, February 22nd rolled around. This was a significant date in the Cutler-Welsh household thirteen years ago when our house was located close to the Avon River in Christchurch. While it was a life-changing day for us, life has gone on. We ultimately lost our recently renovated home in Richmond as a result of the Canterbury Earthquakes, but many lost so much more. What would a moratorium on , tsunami or fire risk areas, look like? How would the resulting plummet in land values impact the economy and further inflate the cost of housing? But if not now, when? The risks are likely...
info_outline Build Aotearoa 2 Principles and Performance.MP3Home Style Green - Sustainable Design and Building
There are fundamental gaps in what the New Zealand Building Code covers and how well it covers the aspects that are included. These reasons should be enough to justify using standards like Passive House or Homestar to go above and beyond the building code. In this series, I'll be looking at reasons why it's better to ask about the value and risk minisation resulting from higher performance standards rather than focussing only on perceived upfront cost.

As I draft this episode, there's a chorus of cicadas outside my window. The sun is shining and there's a faint breath of a breeze. It seems calm where I live, here in a relatively leafy part of Tāmaki Makaurau. But all is not calm everywhere in Aotearoa today, Waitangi Day 2024.
