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.

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!

We were very pleased to have Dr Jess Berentson-Shaw from The Workshop keynote at SPPHC19 (video and slides available here – it is highly recommended watching before making use of the checklist below)

Subsequently, PHINZ has worked with Dr Jess Berentson-Shaw to develop a checklist for our members. It is intended to help you advocate for Passive House by communicating its proven benefits using accurate and compelling story-telling.

It is free to download on the resources page.

Within the industry and media, there are occasionally claims that buildings meet or exceed the Passive House standard simply because they might include particular features or approaches that are similar to Passive House. For example, they achieve a good air-tightness result, include insulation above the building code minimum, or use very little energy for heating. It is incorrect to claim that such a building is a Passive House unless it can be shown to be designed and constructed according to all the certification criteria.

PHINZ have taken legal advice and, based on a similar document from the UK, produced a technical briefing outlining relevant NZ law and clarifying PHINZ’s position on claims of the “Passive House Standard” and how the terms “Passive House” and Passivhaus” should be used in Aotearoa NZ.

PHINZ, Te Tōpūtanga o te Whare Korou ki Aotearoa, the Passive House Institute New Zealand welcomes the government announcement on Thursday (30/07/20) of a planned $500 million investment into the Kāinga Ora – Homes and Communities Retrofit Programme.

The good news is this housing for our most vulnerable people will be made warmer, drier, better ventilated and more airtight. Other positives are the job opportunities this will create within the local communities, and retrofitting of existing homes means that the embodied carbon remains in the buildings.

At this stage Kāinga Ora aims to bring these buildings up to existing new build and Homestar 6-star rating level. However, the government’s recently announced Building for Climate Change Programme and associated consultation makes it clear that the existing building code is inadequate both in terms of ensuring healthy buildings for those who inhabit them, and for meeting New Zealand’s 2050 carbon targets. 

PHINZ CEO Amy Tankard points out that;

“Aiming to the current minimum standard, whilst making the housing much better than it was, means that the newly retrofitted housing will soon fall below minimum standard again. Slightly better but still-not-great buildings will be unlikely to be revisited in the near future, thus Kāinga Ora risks locking in mediocrely performing, high emission buildings for another 50 years.”

Passive House is a building standard with tools and methods to accurately model how a building will perform prior to any building or retrofitting is started. The performance in terms of thermal comfort, air quality, moisture and heating energy use is measurable, and of the highest level. The quality of life that building or retrofitting to Passive House standard can deliver is hugely beneficial to the people living in those homes.

Passive House certified homes are likely to be the only ones that currently meet or exceed future efficiency requirements for the government’s Building for Climate Change Programme and New Zealand’s 2050 net-zero carbon target.

Passive House designers and consultants, a list of which can be found on the PHINZ website, are trained in energy modelling new and existing buildings and establishing the most cost-effective upgrade measures for the best outcomes. These retrofits could be planned to deliver really great, healthy buildings to the Passive House standard. When this is not possible, practical or affordable to achieve in a single intervention, a series of retrofit steps can be planned with a defined target and timeline to reach the desired outcomes.

On Radio NZ on 9 July, Alex Baker, Sustainability Programme Manager of Kāinga Ora said they were looking at Passive Housing, and “We’ve also got 50,000 houses around the country that will need major reinvestment over the next 10 to 20 years. And that in itself is an opportunity to significantly shift the performance of those buildings.”

Te Tōpūtanga o te Whare Korou ki Aotearoa, the Passive House Institute New Zealand, extends our support and encouragement to Kāinga Ora in delivering quality, healthy homes for people, their whanau and communities.
