Derek Ward's strength is the science that connects good design with good performance. Clioma House specialises in 'airtightness and effective insulation'. They help bridge the gap between the drawing board and the construction site.

Matthew Vande and partner Amy Musser created Vandemussser Design to help with 'the technical side of building green'.

They found a great problem when they moved to North Carolina - builders who wanted to do right thing, but didn't know what the right thing was. Matt, Amy and their team now help builders and their clients to find the most cost effective and easiest way to make energy efficient buildings. They help builders to avoid a costly 'trial and error' approach.

As a founding member of PassivHaus Main, I should have guessed that Chris Corson would be pretty passionate about why and how we should build better homes. A quick look at EcoCor's website suggests they are a good place to start for achieving a practical solution to a sustainable home. I caught up with Chris to talk about prefab, Passive House and Passion!

So, you've decided you'd like a really good home. One that's comfortable, healthy and energy efficient. That's great, but unfortunately it's not (yet) standard practice. Hopefully you can find a good designer to help (try this list if you like). But you'll also need some good, non-standard products. This week I spoke with Ken Levenson about how 475 can help you achieve a high performance home.

Three years ago, John Donovan built a demonstration log house on his property in Waitakere. The images in a recent newspaper article caught my attention, as did the mention of 'eco' and 'efficient'. So I tracked John down to get his thoughts on sustainable building with logs. And we talked about pyramids...
