SOME OF THE BENEFITS OF PASSIVE HOUSE (PASSIVHAUS)

Here is a list of some of the benefits of Passive House (Passivhaus):

1. Global Warming: by building a Passivhaus you are helping to do your part towards the environment. In Germany a study confirmed that Passivhaus buildings had an average energy saving of 90 percent over conventional homes.

2. Ultra-low energy bills: Passivhaus has strick criteras for certification. These include the maximum use up to 15 kWh/m2 per year for heating and cooling, as calculated by the Passivhaus Planning Package (PHPP), or a peak heat load of 10 W/m2, based on local climate data.

3. Fresh clean air distributed throughout the building: one of the most important elements of Passivhaus is the mechanical ventilation, which constantly replaces the polluted indoor air with fresh filtered outdoor air that reduces exposure to dust and allergens.

4. Comfort: Passivhaus strives to maintain a comfortable, even temperature throughout the home, with the difference between radiant temperature (i.e. the temperature of windows, doors, and surfaces) and air temperature being small, which assists in eliminating draughts. Thus, you can sit near a window and not feel cold in the colder months.

5. Peace and quiet: due to the high-performance windows and external doors, a Passivhaus reduces the noise from the surrounding environment.

6. Low risks of mould and condensation: Passivhaus is also designed to have a low risk of mould and condensation, both within the building structure and the interiors.

THE GROWTH OF PASSIVHAUS IN AUSTRALIA

Chris Nunn, Australian Passive House Association chairperson, is quoted saying “In light of the dissatisfaction many people have with the current building stock – in terms of quality, and the cost to keep warm and cool – this early growth of Passive House in Australia is the beginning of a new era of high quality, high performance, ultra-low energy buildings that Australians will really appreciate.”

SOUTH-WEST VICTORIA PASSIVHAUS

I recently was fortunate to visit a new build Passivhaus home during construction in a rural setting in South West Victoria. I had connected with the owner via Instagram, and she kindly invited me to visit when I was next in the area.

I grew up in the area, and know how brutal the winters can be down there. The day I visited there was no exception, with torrential rain, high winds, and a top of eight degrees. So it was a perfect day to visit a Passivhaus and personally test it’s high performance.

WHY PASSIVE HOUSE (PASSIVHAUS)?

The main reasons for using the Passive House (Passivhaus) low-energy voluntary building standard for a new build home, renovation, an/or extension are health, comfort, economics, and energy efficiency. One of the key strengths of this building standard, is that studies have proven that the built performance closely matches the predictions of the PHPP modeling software, resulting in no performance gap. Thus, the software is accurate and takes the guess work out of the design stage.
