Build Aotearoa 17: Platinum Homes with Sam Watt 27.07.2024

99 Waiwai Drive, Milldale north of Auckland looks like a regular new house in a regular new subdivision, but around 30 people visited the site mid-build to see why it's different. This showhome will be one of the Platinum Homes high-performance range. It's a SIP (structural insulation panel) construction and achieved a near Passive House level of airtightness. I caught up with Sam Watt, the Genera...

Build Aotearoa 10: Warmer and Wetter 20.04.2024

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...

Many people might be surprised to know that the New Zealand Building Code does not require any consideration of overheating in homes.

There is nothing to prevent homes from being designed with large areas of unshaded north or west-facing glass. Siân Taylor is an Archi...

Build Aotearoa 6: Framology with Pete Hammond 15.03.2024

More is not always better, especially when it comes to the amount of timber in the frame of a house. The more timber there is, the less space there is for insulation. Most homes in Aotearoa are designed using the assumption that timber will make up around 14% - 18% of the area of a wall. A 2020 BRANZ research study found that in reality, the timber fraction is closer to an average of 40%. This mea...
