Everybody was talking about Model and with good reason. Conference organisers gave this property developer and its consultants a lot of time to talk about its concept and the work currently in early design stage. Model describes itself as an “Australian purpose-first build-to-rent group” which is a bit of a mouthful, but its intentions are ambitious: “Our projects – designed …
A new conversation about housing in New Zealand
If you’re in the business of designing, building or advocating for better buildings in New Zealand, you need to read “Homes that meet our real needs“, a BRANZ report written by The Workshop. It’s a deep dive into how New Zealanders think and talk about their homes. Some of the insights will be familiar to those of us who have …
NZ homes are still cold, damp and unhealthy
New Zealand homes are slightly less cold in winter compared to 20 years ago. More New Zealanders appear to be heating at least some bedrooms, some of the time, to some extent. That’s the good news in the preliminary results from the HEEP2 study. It’s faint good news, given other findings. About a fifth of those surveyed said they could …
Useful advice on avoiding household mould
The prevalence of mould in New Zealand houses is a disgrace but it’s also not unique, as this American paper in the latest ASHRAE journal makes clear. The author claims about a third of older and newer single-family homes in the US north-west have visible mould, as these images graphically show. The article outlines causes but also proposes solutions, with …

That was Space Division’s first Passive House build. “We …

The suite of tools and resources, developed with input from the sector, aims to help reduce emissions across the sector. We’ve worked with several retirement community providers in the past and I wish these …
Canada tackles the massive task of greening its buildings
We often look to other countries for examples and lessons learned in the push towards sustainable buildings. A recent article in Canada’s National Observer (July 2024) highlights the significant challenge and opportunity facing Canada in transforming its building industry to meet net-zero targets by 2050. The built environment, including construction, materials, and operations, accounts for nearly 30% of Canada’s greenhouse …
Mapping residential heat demand and resulting emissions
This is a new paper by Jack et al looking at how residential space heating and hot water varies across New Zealand regions with a focus on the amounts and carbon emissions. The idea is that by knowing where the higher carbon emissions are located and what’s going on we could focus on these higher carbon items first. To do …
Palmerston North’s first Passive House
Heartland city Palmerston North now has its very first certified Passive House project, Hokowhitu Passivhaus. It’s notable for a highly-engaged homeowner, a skilled registered architect and a conscientious building team. None of them had prior experience with Passive House but they did choose a very experienced Passive House designer and altogether it went very smoothly. Read on to admire the …
