166 How to Create a Good Thermal Envelope

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Sat, Jul 09, 2016


The building code is the worst house you're legally allowed to build, yet it's often treated as the target.

In this episode, I walk through some building envelope basics and discuss where I think you should invest the most to improve the health and comfort of your new home.

165: Where are NZ Builders making great homes?

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Sat, Jul 02, 2016


I usually interview designers and builders about what's going on overseas, with a focus on what the New Zealand industry could learn. In this episode, I speak with Damon Gray and Andrew Chapman of NZ Builders. They've turned this idea on it's head and have taken some NZ techniques to British Columbia, with some stunning results.

I love it when I find new companies that are looking at the design and building process a bit differently and who want to provide healthy, energy efficient homes. That's what Nook is all about. I caught up with their designer, Warren Clarke recently and asked him why he does what he does.

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

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Thu, Jun 09, 2016


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.

Fri, May 27, 2016


Imagine having a Fitbit for your home and being able to see, in real time, how it's performing. You could also be notified of any hazards like high levels of CO2 and VOCs as they occur - before you start to get a headache or start having respiratory problems.

This week I speak with Dustin Jefferson Onghanseng, a cofounder of uHoo, an exciting new product that could be the Fitbit for your home.

156 Why Passive House with Dr Wolfgang Feist

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Tue, Apr 19, 2016


Wolfgang Feist is attributed as the co-founder of Passive House along with Bo Adamson. Feist, a German physicist collaborated with Adamson from Sweden in 1988 to developed a number of ultra-low energy research buildings.

Passive House is now 25 years strong and at the time of recording, Wolfgang was preparing to attend the 20th International Passive House Conference back where it all began in Darmstadt, Germany.

155: Cassettes & CNC Machines. What's the future of Prefab?

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Mon, Apr 11, 2016


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!

Here are some of my highlights from a well attended and inspiring conference.

152: How to choose the best LED Lighting for your home

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Sat, Mar 12, 2016


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.

151: Passive House is Here!

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Mon, Feb 29, 2016


There's so much that could be said about two days of great Passive House presentations in Melbourne, but I've challenged myself to boil it down to one point per presentation. If there was one takeaway from the second South Pacific Passive House Conference, it was that Passive House has arrived in the Southern Hemisphere and it's going to grow, because it works!

148: How to design for your climate

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Mon, Feb 01, 2016


Graham Hunt goes into a lot of detail when researching the local climate that will impact the comfort of a home. Designing for your climate includes an analysis of both the macro - the temperature, rainfall and humidity of the region, but also the micro - the local wind, shading and exposure of a particular site.

We discuss why this is important and how to do some of the basics.

147 Who's most influential when building a home?

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Mon, Jan 25, 2016


Who's the most influential person in a real estate development, the architect, the owner, the builder...? What about the developer?

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. Steve Glenn's philosophy however is that developers have a huge potential to control what gets created in real estate and he's passionate about creating a good product. The mission of Living Homes LLC is "...to create homes and communities that inspire people, foster family and community interaction, and make modern life easier, healthier and more comfortable..."

Mon, Jan 18, 2016


Angus Crowe believes that you definitely can afford an architect. In fact, you can't afford not to have one.

Learning from design homes in the tropics, Angus now uses a combination of orientation, cross flow ventilation, thermal mass and above all - 3D modelling to produce healthy, comfortable homes.

143: Why is foam such a great building material?

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Mon, Dec 14, 2015


Foam is an incredible thermal insulator. For the price and size, it's about the best insulation material you can get. But many people are concerned about the chemicals and process used to manufacture polystyrene.

I spoke with Curtis VanDyke from RL Adams Plastics about what they're doing to make foam 'green' and therefore make it an even greater building material.

136: Thermal Mass is Not That Useful

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Tue, Oct 27, 2015


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.

117 What's Greenbuild and who's it for?

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Thu, Jun 04, 2015


Lindsay Roberts is the show director for Greenbuild, the premier conference and expo for the green building movement. 

Organising Greenbuild is a 12 month long process, so running the annual event is pretty much a full time job for Lindsay. I thought I'd catch up with her just prior to registrations opening so you've got plenty of time to secure your early bird tickets and join the buzz. 

In 2015, Greenbuild is in Washington D.C. and will take place from November 18 to 20. Mark it in your diary now!

Concrete slab edge insulation is one my hot topics. It seems to spark debate, firstly about if it's worth doing, then secondly about how to do it. I recently spoke with manufacturer and experienced business owner, Mike Peters of Fort Wayne, Indiana who's come up with an easy solution for builders to cut heat loss at the slab edge by up to 88%.

Sounds reasonable. 

But how do you do it?

85: Sustainability vs Resilience

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Tue, Oct 07, 2014


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.

67: Nudura Insulated Concrete Forms

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Fri, May 16, 2014


Nudura is a brand of Insulated Concrete Forms, which as CEO Murray Snider describes, is like giant Lego blocks. When the polystyrene pieces are slotted together and then concrete poured into the central cavity, creating airtight walls, the resulting comfort and thermal performance is impressive. 

Murray was recently visiting New Zealand from his home in Canada and I took the opportunity to find out more about ICF and Nudura.

54 Energy Efficient Homes & MagRoc with Dean Buckeridge

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Wed, Nov 20, 2013


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.

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.

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

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Wed, Aug 21, 2013


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.

  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

Tue, May 28, 2013


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?

32 PrefabNZ with CEO Pamela Bell

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Tue, May 14, 2013


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.

30: Is Passivhaus Relevant to New Zealand?

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Tue, Apr 30, 2013


Is it 'Passive House' or 'Passivhaus'? That was one question I put to expat Kiwi, and architect Elrond Burrell. The main question though, is Passivhaus even relevant to New Zealand?

Elrond currently works as an Architect in the Herefordshire branch of Architype: http://www.architype.co.uk/

In this episode, we also cover:

  • What is Passive House?
  • How can designers and builders of high performance homes compete with the mass market?
  • How important is indoor-outdoor flow and can you still achieve Passivhaus with it?
  • Can Passivhaus be mass produced?
  • What's the role of social media for building professionals?

29: How to Heat Your Water

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Tue, Apr 23, 2013


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

Tue, Mar 26, 2013


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.

23: Sian Taylor - Being a Green Architect

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Thu, Mar 14, 2013


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. 

A couple of references from Sian include:

20: How to Insulate a Concrete Floor Slab

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Fri, Feb 22, 2013


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.

19: Riverhead passive solar design house

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Fri, Feb 15, 2013


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:

http://www.slideshare.net/IngoRatsdorf/riverhead-passive-solar-design-house

I hope this finished product will be an inspiration for your project!

18: How to build to Code 4 for the price of Code 3

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Tue, Feb 05, 2013


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. 

Richard explains what a Code 3 and a Code 4 home is and describes the aimc4.com project that successfully helped the industry produce more efficient and healthier homes, without any additional upfront cost.

17 What you need to know about heating

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Fri, Sep 28, 2012


One of the most common questions I get asked is "what's the best form of heating?"
Much to the frustration of most people, I usually answer "it depends…" The best type of heater for you and your home does depend on many factors, however there are some guiding principles that apply to all cases.
  1. The most sustainable form of heating is passive
  2. The second most sustainable form of heating is wood
  3. Heat pumps (split-system, reverse-cycle air conditioners) are single room heaters
  4. Homes with solid fuel burners are generally warmer than those with electric heating
  5. Your roof won't heat your home
  6. Water is much better at moving heat around then air it
  7. Insulation is always the first step
  8. Insulation is not heating

13 Do you need a ventilation system?

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Wed, Jul 25, 2012


About 10% of New Zealand homes invest in some form of retrofitted ventilation system. But do you really need one, and if so, what for?

In this cast I talk about how to tell if your house is leaky or air-tight depending on it's age, two basic types of ventilation systems and the common symptoms that cause people to want to install a ventilation system. 

Steps to take when considering ventilation are:

  1. What's your problem?
  2. What's your house type?
  3. Insulation
  4. Draughts 
  5. Adequate heating
  6. Extraction of moisture at the source
  7. Whole-house ventilation

5 Central Heating

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Tue, May 15, 2012


In today's cast, I complete our introduction to heating systems with a look at central heating. 

Common to all central heating systems are three main components:

1. The fuel

2. The engine or heater

3. The distribution system - pipes, ducts and outlets

There are two main mediums for transfering heat. Air is common with gas-fired heaters and large ducts but is not as effective as water based systems.

Air ducts can lose up to 1 degree per m of duct. 

Heating that is not true central heating includes inslab or undertile electric element heating, heat transfer and ventilation system.

4 Home Style Green: Heating (part 1) types of single room heaters

comments@homestylegreen.com (Matthew Cutler-Welsh)Author: Matthew Cutler-Welsh
Fri, May 04, 2012


After insulation, heating is the next thing most people look at when improving the comfort and warmth of their home. 

In this episode of Home Style Green, I discuss room heaters:

  • Standared electric heating: electric fan heaters, bar radiators, oil column, wall panel etc
  • Gas unflued heating: And why you should never use it!
  • Flued gas heating
  • Heat pumps or reverse cycle air conditioning

In the episode I refer to the 'carnot cycle'. This is the awesome thermodynamic principle behind air conditioning and refrigeration. Refer again to our trusty Wikipedia for a good article about the detailed physics:

http://en.wikipedia.org/wiki/Carnot_cycle

Of course the best form of heating is free from the sun. But making the most of passive solar heating is a design challenge and there's usually not a lot that can be done to improve this once a house is built.

So if you're trying to heat an existing, cold home, what's the best option?
