A rigorous, scientific method of building high comfort, low energy homes of the future. These illustrations explain how Passivhaus works and how it makes the Fern so special…
Airtightness is simply control of air entering and leaving a building to manage temperature and quality of the internal environment.
This is the combined area of all gaps, cracks and holes in the building envelope; where the drafts come from. See how Passivhaus compares to average.

Insulation is a blanket for your house that slows heat transfer to keep it cool in summer and warm in winter.
A Passivhaus is so efficient, it uses around 10% of the heating and cooling energy of the average house. That means a lifetime of savings.
Passivhaus: 10% of Sydney Average
Sydney Average: 10 time as much as a Passivhaus
Structural thermal breaks eliminate these bridges to keep the interior comfortable all year round.
They also eliminate the risk of condensation, mold, and Sick Building Syndrome when used correctly.
Windows with low conductivity keep the heat outside in summer, and inside in winter. There’s also SHGC to consider, but we’ll leave that for next time…
The Fern is so well sealed for airtightness, there is literally nowhere for cockroaches or other pests to enter the apartments. If you get lonely, you’ll have to open the doors and personally invite them.
Just imagine cockroach-free living in the middle of the city!
As well as temperature control, the HRV ‘F7’ grade filtration ensures you’re breathing clean, healthy air 24/7.
The general construction, and especially doors and windows at the Fern are so solid and well sealed, they easily pass the most stringent acoustic isolation requirements.
The average Sydney apartment was built with little or no regard for peace and quiet for the poor old occupants.
