Four tools for scaling up Passive House adoption: international review
This in-depth international review, The Keys to Successful Passive House Implementation, aimed to identify how to successfully implement Passive House construction at scale. The research was commissioned by the California Public Utilities Commission, which aims to apply these learnings in that state.

How to decarbonise NZ schools
Clear, specific and timely actions to reduce schools’ operational and embodied carbon footprint are contained in a recent Ministry of Education (MoE) report, . The recommendations are excellent and they matter because the Ministry manages a huge real estate portfolio and is a major real estate developer: over 16,000 buildings used by over 790,000 students in 2100 state-owned schools/kura The …
QuickSet all set for updated H1 requirements
Here’s a great summary from QuickSet outlining its practical formwork/insulation solutions that fit with the increased H1 requirements. This includes heated slabs.

Haiku sums up warmer home benefits
Who the hell composes a haiku as the summary in a technical report to a government agency? A New Zealander, that’s who. I love this country. People’s ability to care and be serious—but also irreverent or playful, sometimes at the same time—is something I really appreciate. Winter through to spring Houses keep warm with heat pumps At no added cost. …
Elements of building industry lobbying to delay H1 changes
Like I’ve said before, if we want to change, we actually will need to change. Seems simple enough, right? But many in the “pro-cold-home” contingent of our building sector don’t want to change anything. Andrew Eagle from the NZ Green Building Council wrote a very terse essay for The Spinoff a couple of weeks ago. He was incensed that some …
BRANZ edition of HPCD out now
It’s great to finally pin a bow on this project and call it done. The final version of the HPCD (the High Performance Construction Details Handbook) has now been fully reviewed and accepted by BRANZ and published as External Research Report ER70 [2022]. It’s been a long journey—it began before we’d even heard of Covid-19. There were over 6300 downloads of …
