Home Style Green - Sustainable Design and Building

Dean Buckeridge has been designing energy efficient, passive solar homes in Christchurch for as long as I’ve can remember. Along with Russell Devlin, and Bob Burnett, I hold Dean in high regard for leadership in this field. It’s great to see the rest of the market finally starting to demand more of their knowledge and skills.

In this episode of Home Style Green, we discuss why asthma is the norm in Kiwi kids, how thermal mass can go wrong, the economics of spending a bit more up front, the problem with teenage daughter and having cosy feet.

Dean is also involved with MagRoc. Find out about the benefits of this exciting new product.

Why should all buildings designed for people, be designed by an architect, and how can architects be more influential?

Architects, like all building professionals, need to run a good business to be effective.

Mark R. LePage is an Entrepreneur Architect. He's passionate about the business of architecture, so much so that he writes, podcasts and coaches other architects how to run successful businesses. 

I spokes with Mark about his journey, what makes his architectural practice, Fivecat Studio different, and the influence that architecture can have on people. 

How much time do you spend finding out what your clients need or want?

Chris McKay has built what looks like a fairly regular home for his family on the outskirts of Christchurch. Like many residents, they were forced to leave their previous home following the Canterbury earthquakes in 2011. Now they have a warm, comfortable, resilient home and Chris hasn't had a power bill since moving. In this episode, I find out how he did it.

How important are curtains when it comes to improving the performance of your home? 

As Chad Keven from Heavy Duty Curtains explains, it's not just about the drapes, the curtain track that supports the curtain can also play a big role in improving the insulation properties. 

So how much extra does it cost? Tune in to find out. You might be surprised!

46: How to Measure the Impact of Where Stuff Comes From with eTool

What's the impact of where all the stuff comes from that you use when creating your dream home, and how do you measure it? That's what LCA (life cycle analysis) is all about, and that's what eTool is all about. This week, I talk to eTool creator, Alex Bruce. 

Growing up on a farm helped shape Alex's appreciation for the outdoors. He went on to study Mechanical Engineering and while working in remote north Western Australia, got an opportunity to get into the solar panel business. 

One day someone asked Alex if it was true that solar panels consume more energy to make that what they produce in their lifetime. At the time he didn't know the answer, and set out to find out. 

eTool is now available to help answer that same question for all types of products and materials that go into building your home.

I've just come back from three days at buildnz designex. This week I report back on some of the highlights from the show and some great new products to look out for.

Plus, a question about reducing VOCs and toxicity in a new home:

  1. Don't be fooled by the name 'eco..'
  2. Look for known, third party verification like ISO 14001, Environment Choice or FSC and looked for reporte figures on VOCs
  3. Use Envirospec 
  4. Ask your designer, supplier and builder, to specify, supply and use low VOC and non-formaldehyde products

Home Style Green is here to help people build homes that are good for people and good for the planet.

In episode 30, I spoke with Elrond Burrell and asked if Passive House was really relevant to New Zealand. This sparked some great debate and I subsequently caught up with New Zealand based Passive House designer, Jon Iliffe of eHaus.

eHaus is New Zealand's first building company solely dedicated to building homes to the Passive House Standards.

Among other things, Jon discusses:

  1. How Germany is managing to decrease energy consumption while growing their GDP. 
  2. What was good about 1920s houses and are they still good?
  3. How can you justify the cost of building better?

What would you do if you had 6 months to go away and study whatever you wanted? 

Phil McLean is a secondary school teacher who's passionate about design. He was given the challenge to go and find a topic that would put in the shoes of a beginner learner. 

The result is a fresh perspective on solutions for our building industry. Phil's made his outputs freely available, including a Google Map of the most innovative houses in New Zealand, plus a SketchUp model of his 'Stretch and Grow' concept.

Prefab, (short for prefabrication), offers significant advantages to buidling. House can be:

  • Higher quality, with improved finishing and attention to detail without deterioration from being exposed to the elements
  • Produced quickly, being assembled in a matter of days or even hours
  • Very resource efficient, producing little construction waste (a big environmental problem for the sector)
  • Affordable!

So why are we not doing more of it? 

Bell has lead PrefabNZ since it was conceived and then incorporated directly as a result of her research as part of a Masters in Architecture. She's arguably New Zealand's most expert voice in the industry and is motivated to share the many benefits and some of the challenges of prefab.

Hot water is the second largest portion of energy use in New Zealand homes, accounting for around 30% of the average energy bill, that's equivalent to $650 per year. So what's the best system for your home?

My general advice:

  1. Do you need a new system? Obviously if you're building new, then you've got a great opportunity. Otherwise, if it's not broken, does it need fixing?
  2. Two main types, storage vs continuous flow. Storage tends to be better for any more than two people in the house
  3. Four main fuel types
    1. Wood
    2. Sun
    3. Electricity
    4. Gas
  4. Larger homes or long thin homes may benefit from more than one system

Last week I had the priviledge to attend some of the sessions at the Green Property Summit, jointly hosted by NZGBC and the Property Council. 

A highlight for me was Wade Lange, Director of the Lloyd Ecodistrict in Portland, Oregon. 

Later in the week, while in Christchurch, I attended a great lecture by Associate Professor Susan Krumdeik. Aside from being fun to go back to my old University at Canterbury, this was an inspiring lecture, with some great similarities to the vision that has now become a reality in Portland.

The main event in Christchurch was of course, the rebuld and renovate show. This week I report on my interview with Lifemark and Metro Glasstech.


Monique Alfris and her team sell solar powered lights to people in India. She does this through an organisation called Pollinate Energy, which Monique co-founded in 2012. 

I was inspired by Monique's story after hearing her presentation at the recent Green Cities conference in Sydney, Australia. I really wanted to ask Monique about why Pollinate Energy was created and to see what learning might be applied to housing in Australia and New Zealand.

Sian Taylor trained to be an architect in Cardiff, Wales. When she arrived here in New Zealand, like many others who have experienced homes in colder climates,  Sian was pretty appalled at the state of New Zealand houses.

Since then Sian has gained experience working in prestigious firms such as Warren and Mahoney Architects and joined Queenstown firm, Green Being in March 2012. Sian has been heavily involved in a number of Passive House projects in and around Queenstown.

Demand for high performing homes has grown rapidly and now Sian and her own team of dedicated architects have formed the specialist practice, Team Green Architects. 

At the time of publishing, Team Green is still awaiting their website, but you can find Sian through Green Being. http://greenbeing.co.nz/2013/03/architecture-spreads-its-wings/

In this interview, Sian discusses, among other things, how it's easy to justify spending a bit more up front, on the things that really matter. In some cases, houses they design in Queenstown may require only as little as 10% of the heating cost of a regular (code compliant) house of the same size. This adds up to huge electricity savings right from year 1 of living in the home.

20: How to Insulate a Concrete Floor Slab

Why should you insulate the edges of your concrete slab? 

I was amazed when I discovered how much of the heat loss from a concrete floor can occur out the side of the slab, as opposed to down into the ground under the slab. 

It's as much as 80%. 

That means that most of the heat loss (the energy that you're paying for) goes straight out through the narrow bit of exposed concrete around the edge at the base of the house.

Why is this so? Well there are two main reasons and I go into a bit of detail on the blog. Check out http://homestylegreen.com/insulated-concrete-floor

In this podcast we talk solutions. I interview Craig Lonsdale, a Quantity Surveyor with Maxraft. 

Maxraft is a great solution for insulating the whole of a concrete floor, not just underneath.

Ingo Ratsdorf is a registered architect with Babbage Consultants based in Auckland. 

Having grown up and been trained in Germany, Ingo is very aware of how poorly most New Zealand homes stack up against international standards. 

When Ingo and his family were hunting for their dream renovation project, they were continually overwhelmed with the size of the job they saw. It seemed each house they looked at would need far too much work to bring up to a level of quality and comfort that would satisfy them. 

And so it was that they ultimately realised they would have to build from scratch.

Listen in to our conversation as Ingo explains the inspiration and challenges of building and completing (almost) their dream in Riverhead.

He shares some sound advice for anyone looking at start a building project. 

This podcast is best accompanied by a great slideshow of the build available here on slideshare:

How do you build a code 4 house for the price of code 3? And how do you get industry to solve the problem themselves?

Richard Buchanan is an Associate Director at BRE and Founder of Green Building Consultancy Ltd. I met Richard recently inside a LinkedIn group during a discussion about housing affordability. 

It turns out that while we're all looking around for policy solutions and government intervention here in New Zealand, the UK building industry has already figured out how to build better homes, for less. And they did it by collaborating together.
