Bader Drive and Ventura Street

Bader Ventura comprises 18 Passive House apartments and one 4-bedroom stand-alone home (not built to Passive House standard). Located in Mangere, Auckland the homes are part of the large-scale project Mangere Development bringing around 10,000 new homes to the area over the next 15-20 years.

Bader Ventura is the first Passive House development for Kāinga Ora and Australasia’s first Passive House public houses funded by central government. It is the highest performing development Kāinga Ora has ever designed.

A win for both occupants and the environment, the homes have a reduced operational carbon footprint and will be heated and cooled for as little as $1 per day.

Bader Ventura is an exemplar of innovation and leadership in the sector and is a Beacon Project(external link) as selected by the Construction Sector Accord.

Tackling Climate Change

An innovation pilot, Bader Ventura aims to understand the benefits of Passive Housing and help Kāinga Ora build capability in low carbon construction.

Achieving Passive House performance is a major step forward in providing innovative homes that will help reduce the carbon footprint of our future public houses, while easing cost pressures on low income families and people. The development meets MBIE’s Building for Climate Change 2035 proposed final thermal performance cap 12 years ahead of industry expectation.

Monitoring and Evaluation

Over the next 12 months, Kāinga Ora will measure the performance of these homes to see if the predicted benefits are realised. This means measuring indoor air temperature and humidity, air quality, hot water and electricity usage.

This information is critical to informing future Kāinga Ora build standards, supporting the wellbeing of our customers and improving sector-wide knowledge and capacity.

We are committed to using our size and scale to influence improved performance across the wider sector, and will continue to share lessons learned and collaborate with the industry.
