Rank #1: 44 How to Make Things Better with WikiHouse NZ
Danny Squires and Martin Luff met on Twitter, were inspired by a TEDex video and have since co-founded WikiHouse NZ. With this project, they're setting out to change the world and to 'make things better' by design.

Rank #2: 99 Prefab, Passive House & Passion!
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!
Rank #3: 64: 'Co-Housing' Doesn't Mean 'Commune'
What comes to mind when you hear the term ‘cohousing’. For many, there many be some negative connotations. The reality though is that there are so many advantages to sharing some things with your neighbours, while still maintaining a strong sense of privacy and your own space.
Robin Allison trained as an architect in order to help create a more sustainable future. She ended up initiating what was to be become Earthsong Eco-Neigbourhood.

Rank #4: 74: Ecotech Homes Modular Building Solutions
Would you buy a prefabricated, modular home made in China?
Ecotech Homes are versatile, modular housing solutions. I caught up with their Major Project Director, Craig Nisbet just before he took off to Ghana to talk about prefabricated, affordable, quality homes.
I found out there are some good reasons to consider factory built, modular homes.
Rank #5: 26: Efficient Design and Airtightness - Home Show Highlights Part 2
Part 2 of my interviews from the Rebuild and Renovate Christchurch Home Show. This week I catch up again with Bob Burnett. Bob is Homestar trained Architectural Designer who I interviewed about thermal modelling in episode 14.
I also speak with Thomas van Raamsdonk from Pro Clima about airtightness, blower doors and how to seal a three dimensional joint in framing around a window sill, using one piece of tape.
Rank #6: 13 Do you need a ventilation system?
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:
- What's your problem?
- What's your house type?
- Adequate heating
- Extraction of moisture at the source
- Whole-house ventilation

Rank #7: 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.

Rank #8: 41. Save Time. Save Money. Save the Planet! Ecodeals with Lisa Madarasz
Lisa Madarasz was frustrated by not being able to find good products for her home that were going to be good for her family and good for the planet. (Does that sound familiar?)
With so much 'eco' marketing out there, how can you tell what's truly green?
To help, Lisa created Ecodeals.co.nz
Rank #9: 63: Ground Source Heat Pumps with Huw Williams
What other form of heating provides a coefficient of performance, around 5 - 7? That’s the promise, and the reality of ground source heat pump technology.
This week I spoke to Senior Hydrogeologist at Geoscience Consulting NZ, Huw Williams about this amazing technology. We discuss if it’s suitable for houses in New Zealand and why Huw is so interested in ground source heat pumps as a sustainable technology.
Rank #10: 87: Project Management for Design & Construction
Do you need a professional project manager for either the design stage or the construction stage of your building project? I discuss the basics of good project management with podcaster, engineer, business owner and soon-to-be author, Cesar Abeid.
Rank #11: 180: Why adding Insulation can cause moisture problems in buildings
When Prof. Dr. Hartwig Künzel was studying Chemical Engineering, his father was a scientist at the Fraunhofer Institute. Hartwig followed in his father's footsteps after becoming interested in the preservation of heritage buildings. He soon discovered that he could apply his engineering training to diagnosing the moisture problems that occurred after buildings were insulated.
Rank #12: 194: Ecokit - A Prefabricated Energy Efficient Home
Camilla Novotna always knew she wanted to build her own timber house. It was just a question of when and where. Despite not having a formal architecture or building background, Camilla has now done a lot more than design her future home. Along with her sister Pavla, she has created Ecokit - a prefabricated building system offering energy homes that can be put together by anyone.

Rank #16: 17 What you need to know about 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.
- The most sustainable form of heating is passive
- The second most sustainable form of heating is wood
- Heat pumps (split-system, reverse-cycle air conditioners) are single room heaters
- Homes with solid fuel burners are generally warmer than those with electric heating
- Your roof won't heat your home
- Water is much better at moving heat around then air it
- Insulation is always the first step
- Insulation is not heating

Rank #17: 174: Design Housing, not just Houses
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.
Rank #18: 195: Passive House is a Meaningful Applied Physics
Jessica Grove-Smith has a Masters degree in Physics from the University of Sussex, UK. She's studied in Australia and Spain, done volunteer work in Africa and India and completed an internship in Denmark. She wanted to do something meaningful with her knowledge of physics, and in 2008 Jessica began another internship, this time at the Passive House Institute in Darmstadt. Now she's a Senior Scientist and Director at the Institute.
Rank #19: 191: New Zealand's First Passive House Cohousing Project
The first New Zealand Passive House was completed in 2012. Since then, about 20 more individual private houses have been Certified using the internationally recognised standard. Now, New Zealand is about to get its first Certified Passive House Cohousing project and Tim Ross has been involved almost right from the start.
