This report reviewed detailed test measurements for air tightness and heating loads for passive houses and non-passive houses designed to meet an energy target. From this data the Passive Houses (Passivhaus in the UK) predicted performance matched quite closely to the measurements compared to other non-passive house designed buildings. “Most of the homes were fitted with mechanical ventilation with heat …
10 October 2018 Crux Kerrie Waterworth: Why do we still build the wrong houses?
“I like to build for people, not for profit”. Quote from Isaac Davidson “If we’ve got a subdivision of 1600 new homes to build, you have to ask is it cheaper to build them to low specifications or build a new power plant, because that is where we are going.

11 October 2018 Now To Love: Congratulations Professor Philippa Howden-Chapman – NEXT Woman of the Year 2018!
Our congratulations to Professor Philippa Howden-Chapman as well. I’ve had the opportunity to meet and hear her important research on the direct relation between really bad housing and bad health in children in New Zealand. The huge health care costs of choosing to build poor quality housing is shocking. And that is just the money never mind all the misery and …

We’ve two multi-family projects in NZ that …

Calling All Passive House Builders
I’m helping to set up a session of hands on builders to each speak for 5 minutes at the next Passive House Conference in Wellington (9th and 10th of February). The concept is to have some real hands on discussion from folks actually building Certified Passive Houses rather than all the talks being from design folks. You would all be speaking together …
20 September 2018 Passivhaus is affordable and effective, why isn’t it legislated?
This well written article reminds us that buildings in Australia (and NZ as well) are a large contribution to our CO2 emissions and we have the skills needed to significantly reduce that and at the same time save occupants on their energy bills with increased comfort. So if we have the skills and everyone benefits when we build Passive House …
