Australian Passive House Association (APHA)

The Australian Passive House Association (APHA) is an independent, not-for-profit organisation which aims to lead change by educating, promoting, and supporting the delivery of Certified Passive House buildings in Australia. Our vision is that all Australians live and work in healthy, comfortable, low energy, resilient buildings.

Global Alliance for Buildings and Construction

The Global Alliance for Buildings and Construction (GlobalABC) works towards a zero-emission, efficient, and resilient buildings and construction sector through:

  • Raising ambitions to meet the Paris climate goals. While the sector is a major emitter, it also holds huge potential for improvement. We work to raise the level of ambition in retrofitting existing buildings and future-proofing the investments that we will see going into new buildings over the next 15 years.
  • Mobilizing all actors along the value chain. Faced with a fragmented value chain, all stakeholders – from design to construction, operations and demolition in the private and public sectors – need to play their part. We encourage policy frameworks that promote both uptake of existing, cost-effective solutions and private sector innovation – using sustainable public procurement as a lever to create markets and investor security.

Reimagined Habitat

In a changing world, disrupted by climate change, disease, economic uncertainty and anxiety, the one constant refuge is home. We spend over 90% of our time indoors, and with more work time now at home instead of our workplaces, our well-being, comfort, health and the way we touch the earth at home now take on even greater significance.
We need to reimagine our habitat- both in how it works for us, and how it works in the rest of the world.

Understanding that current building methodologies will not survive the changes required to meet the needs of healthy, comfortable, efficient homes demanded by you, the home owner, or meet the global energy targets set by Governments the world over, we asked ourselves what will the ‘new normal’ look like in building thinking in 10 years time, We researched many models to find global best practice. The design principles needed to allow for individuality and design to remain at the core of the process, but result in the healthy, comfortable, low energy homes our clients were asking for. And, it had to be scientifically verified and tested.
Passive House is that global standard bearer for healthy, environmentally conscious homes.

Engineering is about creating
Engineering is as much about mathematics and science as it is about architecture and space. We must understand all of these at the highest level if we are to do our work to the high expectations our clients demand, and that we set for ourselves. We focus on the skills of our talented staff, which allow us to collaborate at a different level to other engineering firms. From preliminary advice and sketches, through the design stages and into site work; our contributions are at a different level.

Limitations that are celebrated
Engineering solutions must ensure a safe and serviceable structure. It must be cost efficient and it must fit into the architectural vision and project brief. It is important to celebrate these limitations and not to see them as hinderances. This is backed by our clear vision on sustainability. Sustainability starts at the beginning of a project and carries through to the end. – It is not an add-on but is fully integrated into our process. At each stage in the design process our choice of materials must satisfy our four tiered sustainability criteria: is the solution durable, flexible, economical, and considered. Finding ‘a’ solution does not mean finding ‘the’ solution.
