What are the important things that make your life comfortable..healthy…happy? If you scaled that idea up to your community, have you ever thought what that community might look like? Would it be a place where you’re not shivering by a fire at night so you don’t spend too much on power? Or where your child isn’t coughing from the mould in their bedroom or the condensation down their windows in the morning? Or would it be walking into a school or workplace in winter and staying comfortable all day so you can think on more important things? In that community, would it be taken for granted that everyone naturally had access to that comfort and health?

We wanted to find this out too, and to see what differences were being made in the community by doing the Passive House courses at the ground level. What we received was an inspiring insight from Certified Passive House Tradespersons Glenn Harley from Harley Builders and Lenny Basham from Basham Building Ltd

Here’s what Glenn had to say….

By the time I signed up for the Passive House Tradesperson course, our company had already completed a couple of Passive House projects. The course offered by PHANZ dovetailed (sorry) nicely with the practical realities of a Passive House build.  I found the opportunity to calculate U values of various building materials interesting and applicable.  We got a window (there I go again) into European building techniques and products.
Kara has a witty and direct style honed from many years of teaching people how to build better. She is a fantastic resource available right here in Aotearoa.

And Lenny highlighted how the CET course made a tangible difference to him and his business….

As a passionate carpenter, I would highly recommend the Passive House Tradesperson Course. Previously, I had attended a Primer in Wellington. So I thought I had a reasonable understanding of what a Certified Passive House was. However, after completing the course, I had a much more comprehensive knowledge base on all things Passive and a lot more confidence in the field.

There have been many benefits to completing this course. It has enabled me to have educated debate with designers and engineers on how a building will perform. This has allowed me to dictate material choices and approaches to design. These professionals have been grateful to have someone that knows about thermal bridging or allowing for services such as ventilation in the design stage. This has then made the build easier.

The course gave me knowledge so that I have been able to work with designers in the certification process of a Passive House. We would’ve missed a heap of documentation such as key photos or detailing around airtightness if I had not completed the course. This would’ve been costly financially or we wouldn’t have a building that achieved Passive House standard.

Another bonus has been the ability to impress clients on how a home can perform and school them up on Passive details and design. That has seen me win a couple of tenders where competitors didn’t know about heating demands and the importance of good design.

The whole concept of a Passive House can be quite daunting at first. There’s so much detailing and numbers to get your head around compared to a standard build. A lot of it is quite intellectual and scientific. As a carpenter, you wonder what its relevance is, when all you want to do is build a quality home? The course helps bridge the gap between the design nerds behind the numbers and the fellas onsite who actually create the beast. The CET Tradesperson course gives you confidence to navigate through the whole process and it would simply be a whole lot harder to build a Passive House if you didn’t school yourself up first and do the course. I highly recommend it.”

The next in-person Certified Passive House Tradesperson’s course is happening in Auckland in May. You can find all the info on this, along with courses for Designers and Consultants at phanz.co.nz

On 29 November, MBIE released the 2021 update to the building code. The main changes include increasing insulation requirements and changes to Acceptable Solutions and Verification Methods.

However, quietly tucked way in H1/VM1 Energy Efficiency Verification Method is a section that now recognises the Passive House Planning Package (PHPP) as a modelling tool that can be used as a means of compliance.

This is really exciting because although the methods required for compliance with the Building Code still leave plenty to be desired (read out position paper here), PHPP is a reliable and accurate modelling tool when used correctly. Passive House designers and consultants receive training in the use of PHPP as part of their CEPH2 course and some of them offer it as an independent service – see certified Passive House designers and consultants here.

If you want to buy a copy of PHPP, we are a licensed reseller and you can purchase it from our online shop.

A Kāinga Ora social housing project in Māngere, Auckland has passed pre-construction review and is now on track to become the first central government funded Passive House social housing in Australasia. Construction on the 3 level, 18 unit “Bader Ventura” project is due to start by the end of this year, and to be completed by mid-2023. There are currently also another seven Kāinga Ora Passive House projects in the design phase, all 3 level walk-ups in Auckland. 

PHINZ CEO Amy Tankard paid tribute to Kāinga Ora’s vision in adopting the Passive House standard for this development.

“It’s fantastic that Kāinga Ora is taking the lead in starting to build housing that will not only keep occupants warm, dry and healthy, with minimal power bills, but also takes a big step towards meeting MBIE’s Building for Climate Change proposed 2035 targets. 

Kāinga Ora is the main housing provider in Aotearoa New Zealand, and therefore this commitment has massive implications for the future of building here. Bader Ventura will demonstrate that it is achievable to build to Passive House standard at scale. It will give certainty to suppliers and other Passive House industry professionals, and widen the knowledge base and awareness of Passive House”

Key partners on the project include PHINZ members 

Peddlethorp – Architects

Oculus – Passive House lead and facade engineer

Sustainable Engineering – independent certifier

Congratulations to all who have progressed the project to this point. We will be following with interest!

The number of certified Passive House projects is growing fast in Aotearoa NZ. And with Passive House being in the media more frequently, PHINZ is often asked how many Passive House projects there are in Aotearoa NZ.

Unfortunately, this question does not have a straightforward answer.

Passive House certification is an independent process undertaken by an accredited Passive House certifier and PHINZ, as a charity, has no role in certifying projects. This also means we don’t keep a complete list of all certified projects.

Many certified Passive House projects get submitted to the international Passive House database, however, this is voluntary and therefore not comprehensive. There are currently (as of 07 September 2021) a total of 56 certified Passive House projects in Aotearoa NZ listed on the database. These include:

  • 47 certified Passive House Classic dwelling units made up of 27 certified projects as some are multi-unit.
  • 8 certified Passive House Plus projects
  • 1 certified Passive House Premium project

Current figures can be found on the international Passive House database using the advanced search function.

As noted, there may be other Passive House projects not on the database.

Additionally, one of our members, Sustainable Engineering, maintains a map of certified projects in Aotearoa NZ and Australia.

We are aware of many more projects being developed that are targeting Passive House, not least the exciting project announced by Kāinga Ora today and in the news here also.

PHINZ is currently developing a project directory for our website. This will showcase Passive House projects in Aotearoa NZ and the builders, designers and component suppliers involved.

There are also number of Passive House projects showcased on the PHINZ youtube channel – check them out and subscribe to see more in the future!

Please note that Passive House is an as-built building standard and is protected by consumer law. Projects that do not meet the standard cannot be referred to as “Passive House” regardless of what they might claim. For more details on this please see our article on Claiming the Passive House standard.

Two exciting new developments are in the pipeline, advocating for Passive House to provide healthy and energy efficient new homes.

1. Bushland Park

Bushland Park near Christchurch offers houses that have already been designed to target Passive House certification. The project has been designed by certified Passive House designer Karen Manson, of PHINZ member Meta Architects, and will be built by certified Passive House tradesperson, Peter Bielski of PHINZ member Ethos Homes. This is a fantastic opportunity to purchase your very own Passive House.

Please visit the website Bushland Park for more information.

2. Greenwood Lane

Bellbird Developments, started by Vicki Spearing in 2019, will be providing owners with incentives for building energy efficient homes at Greenwood Lane. Up to $20,000 in cash back incentives are available for those building beyond Building Code and meeting specific Heating Demand figures and airtightness testing results.

Anyone building at Greenwood Lane will be required to model their design with an approved Passive House designer and will help to cover these costs. They will also contribute towards the cost of Passive House certification. Not surprisingly, all sections are already sold!
