Design your home with a Sustainable future in mind

3 Oakley will be the world's first Passivhaus Premium housing development *

Built right here in Adelaide. This world first development is built for a 100% renewable energy future.The development is all electric with each home generating up to 7 times the electricity they consume

*means the world’s first Passivhaus Premium detached housing development with each house individually certified

Here's what we do

Whether you have an idea, a concept sketch, or fully documented drawings, we are able to take that through to completion and certification if required.

We understand that creating your dream home can be a very exciting and passionate process. It is not only a huge investment in time and resources, but also a massive investment in your family’s future. We are also passionate, about creating homes and about Passivhaus. It excites us to take an idea, turn that into a concept, put it into the Passivhaus software, and see the results. By using the software as a design tool you get to see the bare bones of how the design behaves and you then use that feedback to make it better.

World's leading standard

Passivhaus is the worlds most rigorous standard in energy efficiency, comfort and sustainability for buildings.

This is because Passivhaus uses a ‘fabric first’ approach where the primary focus is not about heating and cooling, it is about the level of comfort for the occupants. Passivhaus outlines the metrics that need to be met for a building to be considered a high performance building. These metrics not only include thermal comfort, ventilation, indoor air quality and acoustics, but also others aspects like temperature asymmetry and stratification, and the air velocity of the ventilation system. The fact that Passivhaus looks at all components and aspects of the building makes it the World’s most rigorous and complete performance based standard, bar none.

Global warming

No-one really knows what climate conditions we face in the future. What we need is some sort of insurance so that we are able to cope with this uncertainty.

Buildings are responsible for 40% of the carbon emissions that are causing such problems for our future survival. Up until now the simple solution has been to burn fossil fuels for our heating and electricity. These fossil fuels are non-renewable. They are a limited resource and their use impacts on global warming. For this reason Passivhaus created the Premium and Plus classes. Their focus is on future-proofing your house against this uncertainty by promoting renewable energy, going all electric and reducing our building’s environmental footprint so that we can make the most of our finite resources.

Rigorously tested

Each building goes through a thorough audit and is then tested using the Passivhaus software (PHPP).

Passivhaus buildings need to maintain a constant temperature range between 20°C and 25°C. In order to ensure that the design can achieve this, accurate energy balance calculations need to be undertaken using the Passivhaus software, PHPP. The building needs to be broken down into its individual parts and assessed. The certification process is a quality control system where the model is independently checked and verified. During the build stage all items need to be documented and logged for verification. Air-tightness needs to be checked at various stages before a final independent test to confirm 0.6 ACH@50Pa. Finally, for certification all the data is sent to Germany before final approval after which it is registered on the International Passivhaus website.

Fresh filtered air

Every room gets a steady stream of fresh filtered air supplied by the balanced ventilation system.

The “lungs” of a Passivhaus is the mechanical ventilation system with heat recovery (MVHR). It allows an air-tight home to still breathe when the windows are shut. The MVHR constantly exhausts the stale air and replaces it with fresh filtered air free of pollens, dust and other pollution. The heat recovery unit is able to recover about 90% of the heat so that the cost of maintaining an even temperature is minimized. The system give you the choice to leave the windows shut all Winter or when it is too hot. When the weather is beautiful you just open your windows and enjoy.

Free heating and cooling

Adelaide is blessed with an almost perfect climate for building low energy high-performance buildings.

But you have to take advantage of the local conditions. By placing high quality double glazing on the northern elevation that is suitably shaded, we can access free winter energy from the biggest heat source we have, the Sun. In summer, we can access free cooling by utilizing un-insulated slab on ground construction. Because we have an excellent ground temperature profile, the slab acts as our free summer air-conditioner. In-fact at 3 Oakley, the summer heat load being drawn out through the house slabs is 70 to 90 times the heat pump air-conditioning cooling requirements. The slab is passively doing all the heavy lifting during Summer while the heat pump air-conditioner is there to take the edge off those peak heatwave conditions that we experience in Adelaide from time to time.

100% Renewable energy

Every inch of our homes are not only beautifully designed, they are calculated and built to surpass the World’s most rigorous energy efficiency, comfort and sustainability standards for buildings. Every component, every wall, window and even appliance is taken into consideration when meeting the Passivhaus performance standards

To date there have been over 60,000 Passivhaus units built around the world.

Want to learn more?

Passivhaus is an international standard for energy efficient buildings where a house  is so well insulated and air-tight that it can function with minimal heating and cooling.  Passive house projects deliver the highest level of comfort, and a cost effective bundle of energy saving strategies and renewables.
