In the past decade, passive design and Passivhaus principles have notably transformed Australian architecture, marking one of the most significant shifts in the industry.

Originating in Germany, the Passivhaus movement has introduced a groundbreaking approach to creating energy-efficient, comfortable, and sustainable buildings.

In Australia, the adoption of Passivhaus principles signifies a major change from traditional building methods, driven by increasing awareness of climate change, rising energy costs, and a commitment to sustainable living.

Contemporary Australian architects are embracing passive design strategies, such as optimising building orientation for natural light and ventilation, selecting appropriate materials, and utilising thermal mass to maintain indoor temperatures.

These strategies not only decrease energy consumption but also enhance occupant comfort and well-being.

By decreasing dependence on mechanical systems, Passivhaus principles help lower greenhouse gas emissions and reduce carbon footprints. These designs can lead to substantial cost savings for homeowners through lower energy bills.

But there are many ways to optimise sustainability and keep construction costs to a minimum while still meeting Passivhaus standards.

Is Passivhaus suitable for the whole of Australia or only some parts of the climatically diverse Continent? Is it time for an Australian Passivhaus standard?

To discuss this, on the first panel we’ll have Heather McCabe, Architect + Certified Passive House Designer at DJRD Architects, Andy Marlow, Director at Envirotecture, Matt Kennedy, Director at Arcke, as well as Geoff Marsdon, Executive General Manager at Bondor Metecno.

“Passivhaus is a science-based, real world verified approach to delivering the healthy, comfortable, smoke tight buildings that Australia needs for this century,” says Marlow.

“If operational energy is to be reliably quantified during the design process then air tight, appropriately ventilated buildings are the way to achieve that; “she’ll be right” no longer cuts it.

“The Passivhaus standard has delivered predictable results for over three decades. At a point in time where we need results not talk, we are faced with a choice; to reinvent the wheel or to roll with the tried and tested. We don’t have the time to waste.”

McCabe is adamant: Passivhaus is a sine-qua-non principle of sustainable living.

'When considering how to create spaces that are equitable, healthy and liveable for all, the application of Passivhaus principles just make sense,” she says.

This panel represents some of the most accomplished leaders in the sustainability field who will explain the current climate of the passive design industry and plant the seeds to help the next generation achieve a much more diverse and sustainable future.

The 2024 Sustainability Summit will be held in Sydney on November 14.
