Bert Sarkinnen has been building homes since he was 16, firstly alongside his Father who was also his teacher and mentor. Along the way Bert fell in love with the craft and beauty of timber framed buildings, so much so that he created Arrow Time Framing to specialise in this type of construction. As creators of beautiful, high quality buildings, Arrow Timber Framing is now 'the enemy of ugly'. In this conversation, we discuss the importance and value of a craft, how being encouraged to makes mistakes helped Bert to learn, and the challenges of building a business.

The Headwaters in Glenorchy, just 45 minutes drive from Queenstown is a magical place and now home to another Living Building Challenge project.

I caught up with lead consultant, Tricia Love recently to discuss how she got involved and what the Headwaters is all about.

The Headwaters doesn't aim to re-invent the wheel. It is however a leading example of how we can learn from what's being done overseas and contribute our own expertise towards a positive effort of creating better places to live, work and play.

Karen Manson likes thinking about and designing housing, not just houses. With over 15 years of international experience, Karen now has her own practice in Christchurch. She focuses on high performance houses, including Passive House. I had the opportunity to chat with Karen at the pro clima HUB about her journey. In this episode we discuss the urban design, keeping it simple and what can be learnt from the process of designing standard, code compliant buildings.

Nearly all building elements (roofs, walls, floors, window and door joints etc.) will leak at some point. Problems only occur when moisture gets in, and stays in. If moisture is allowed to accumulate for extended periods, then mould grows, timber rots and metal corrodes. Ultimately, people get sick and our buildings start to fail. This can be incredibly disruptive, stressful and expensive!

WUFI® was created to allow designers to check their designs before those designs become real buildings. By running scenarios with different combinations of products we can fail in the virtual world until we optimise the design. Then we can build with confidence that our real structure will stay dry, healthy and strong for decades.

How do you make eco, affordable?

As project manager for the proposed Lotus Eco Village in Paraparaumu near Wellington, Simon Wallace has some good ideas.

In 1971, Eric Doornekamp led a group of yoga enthusiasts to establish the Lotus Yoga Centre and Retreat in Aro Street, Wellington. Almost half a century on, the Lotus Yoga Centre Charitable Trust is branching out and developing an Eco-Village.

The Lotus Eco Village will be built in on a 3 hectare site purchased by the Trust back in 1985. Project Manager Simon Wallace shared with me how he plans to create affordable, healthy houses alongside a yoga and community centre in a great location.

163: What are the layers you need in your wall?

Walls (and roofs and floors) of buildings have become complicated. As we’ve increased the level of insulation, we’ve created some new problems, like condensation. This has been aggravated by the addition of layers into the wall that reduce air movement. So how do you create a wall that keeps you warm but will also stay dry? I spoke to Jon Davies from Pro Clima to get some facts about airtightness.

It’s tempting to say that Prefab’s time has come, but I don’t think this does justice to prefabricated building. As Pamela Bell has explained previously on the Home Style Green Podcast, Prefab is not new. But the enthusiasm shown during this week’s PrefabNZ CoLab event here in Auckland suggest that prefab will play an increasingly important role in the delivery of buildings.

Some would even go so far as to say, there’s a revolution about to happen!

Remember when the main choice you had for light bulbs was 60 Watts or 100 Watts? Things have progressed a long way since then, and mostly for the better, especially when you consider that the average incandescent light bulb is only about 10% efficient. Most of the energy ends up as heat rather than light.
Now we've transitioned through compact fluorescents (CFLs) to light emitting diodes (LEDs), there's a lot more to understand about what makes a good light.

In this episode, I speak with David Maunsell from Switch Lighting to uncover the details about why some LEDs are much higher quality than others. Unfortunately it's still the Wild West out there in lighting retail land. Hopefully this can help you figure out what's important for lighting.

Real estate developers are often seen as the bad guys, out to make a bunch of money without really caring about the quality of homes of lifestyles resulting from their work.

Passive House vs Passive Solar with Lloyd Alter

Much of this comes down to two design principles which are similar in name and have some overlap in their detail, but are fundamentally quite different. As Lloyd Alter points out, the 'Superinsulated' house was really the origin and (along with airtightness) is the basis of Passive House design.

'Passive solar' design is what's in question here, in particular the reliance on thermal mass and sun angles.

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...

Homestar is New Zealand's comprehensive environmental rating tool for homes. It's Green Star for the residential sector and is not some crazy Kiwi start up idea. It's very closely related to successful international precedents such as LEED and Code for Sustainable Homes. But how much does it add to the cost of building a home? 

There are some inaccuracies out there that I think need addressing.

Resilience and sustainability are different. Sustainability feels more long term to me. It's about using resources wisely with future generations in mind. Resilience is more about weathering the storm. There is an overlap and so both are important.

If being resilient encourages people to invest in rainwater harvesting and solar panels with battery backup, thereby also being more sustainable, then surely that's a good thing for everyone. 

Is one more important than the other, or can resilience be a really handy way of selling sustainability?

Plus, my top five tips for having a resilient home.

Most of us are familiar with leaky buildings - the perfect storm of poor design, poor cladding systems and poor workmanship, culminating in allowing rain to get in. Now we've moved on and have cavities, more stringent weather-tightness checks and hopefully we like eaves again.

So what's leaky buildings 2.0? If we've dealt to the risk of moisture coming in from the outside, where else can moisture come from?

Mark experienced his own building project as a client in 2004 and recognised the need for better information. He was handed a copy of the Building Guide from the local Council. 

The Building Guide was a different publication then and Mark saw potential for how it could help prospective homeowners get better information. So in 2006, Mark Graham bought the magazine. 

He explains to me why he hated advertising - the very industry he worked in for 14 years, and how he now relies on it. What's the difference?

Dan Heyworth is on a mission to improve the range and quality of houses available to New Zealanders. 

After returning to New Zealand from UK a few years ago, Dan realised there are really only two main options for getting a house built, either going to a building company for a cheaper, mainstream house; or going to an architect for an expensive one. 

Box Living is both an architectural firm and a building company. Dan and his team are passionate about bringing the benefits of architecturally designed homes, to everyone.
