Certified Passive House Builders
The future of healthy housing is here. Improve your family’s health, comfort and environmental impact with a Passive House.
The benefits of a Passive House far outweigh other forms of building, even other forms of sustainable housing. You won’t get a more comfortable, healthy home than a Passive House or one that is more friendly to the environment.
We believe in the benefits of Passive Houses so much, that we built our very own Certified Passive Display Home called ‘The Sapphire’.
Our Certified Passive Display Home ‘The Sapphire’ has:
Up to 90% energy saving in the home
Improved fresh indoor air 24/7 using a ventilation system throughout the house
Carbon zero status with the addition of LG solar panels
A reduced carbon footprint using less energy, sustainable materials, waste management onsite, energy efficient appliances and water efficient tapware
Reduced auxiliary heating and cooling with climate appropriate insulation, triple glazed windows, air tight membrane and ventilation system
Low toxin living with reduced exposure to mould and other toxins
Understanding Passive Houses
At Blue Eco Homes, we’re thrilled to be builders of Passive Homes. While fairly new to the Australian landscape, Passive Houses have been being built for years in Europe, where they often use the German term Passivhaus. Passive Houses are heralded for being healthy, comfortable and environmental. They are the world leading standard of energy efficient construction and can be built anywhere!
A passive house delivers a healthy indoor environment combined with ultimate comfort – all while using very little energy. Due to a perfectly calculated construction and clever air filtration system, the internal temperature constantly stays between 20°C – 25°C, no matter the changes of the outside world.

Passivhaus foundational principles
Extreme Air Tightness:
- Airtight construction ensures that only fresh filtered air enters the home
- A Certified Passive House requires air leakage to be tested near completion and must be below 0.6 air changes per hour.
- Airtightness is as beneficial in keeping heat out as keeping it in, ensuring the great internal climate you experience in a Passive House.
Continuous Appropriate Insulation:
- The unique nature of a Passive House means they’re perfectly calculated for the individual climate. This means the amount of insulation needed is dependent on these calculations also.
- In many cases a Passive House might not need much more insulation than code compliant buildings.
Mechanical Heat Recovery Ventilation (MHRV):
- An MHRV system continually draws filtered outdoor air into living spaces and bedrooms and exhausts stale air from bathrooms and kitchens. This delivers fresh, tempered air to the home.
- These systems use very little energy as they move relatively small volumes of air
- This concept of heat recovery, is proven to be an efficient and healthy choice for your home, as well as having low energy use, no drafts or no noise
High Performance Windows and Doors:
- Windows are the biggest source of heat loss and gain in all buildings. This is no different in a passive house, although the loss and gain are much more balanced.
- Dependent on climate, windows and doors utilize either double or triple glazing to maintain indoor climate and minimal energy use.
- A critical element for Passive House success, is high quality insulated frames that seal tight.
- Compared to the average house window, the windows of a Passive House will transmit just one-sixth of the heat compared to a typical Australian window.
No Thermal Bridges:
- A thermal bridge is a physical pathway from inside to outside the building through which heat can move easily. This often results in mould, condensation, drafts and other discomforts.
- Poor quality windows, uninsulated concrete slab edges and steel framed buildings are all examples of common thermal bridges.
- Passive Houses aim to eliminate thermal bridges within the home, therefore improving health and comfort.
