Greta Thunberg, a 16 year old climate activist delivered this powerful talk in August 2018. “The climate crisis has already been solved. We already have all the facts and solutions,” Thunberg says. “All we have to do is to wake up and change.”

The Passivhaus Planning Package – more commonly referred to as PHPP – is a building performance modeling tool for designing low energy buildings.
It is necessary element for Passivhaus design, and for Passivhaus Designers and Consultants, along with Passivhaus Building Certifiers.
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.
This is a great video explaining the difference between Passive Solar Design and 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.
Typically speaking, Passive Houses in Melbourne do require an active heating and cooling systems. However, systems can be as simple and as economical as one or two split systems, in opposed to a more expensive ducted heating/cooling system and or a hydronic heating system.
The Passive House energy standard – otherwise known as Passivhaus (the German spelling) – was born out of a conversation between Bo Adamson of Lund University, Sweeden, and Wolfgang Feist of the Institute for Housing and the Environment, Darmstadt, Germany. Their concept was developed through research projects with grants from the central German state of Hessen.
This is a great video about a Passive House in New Zealand, where the house doesn’t require a heating or cooling system. For Passive Houses in Melbourne it is recommended that you have a heating and cooling system – which can be as simple as one or two split systems – which are used on the rare occasion where the climate is at it’s extreme.
