Asquith PurePassiv: A pioneering Passive House in northern Sydney, showcasing premium efficiency, bushfire protection, and innovative prefabricated construction, setting a new standard as Australia’s first As-Built rated Green Star Home.
The form of this Passive House designed by Envirotecture is driven by a desire to seek maximum efficiency, in all senses of the term, while having a scale and texture that talks to the bushland surroundings of the northern Sydney suburb.
While all certified Passivhaus projects are incredibly efficient and comfortable, this one leads the pack with its Premium certification; one of only 17 in the world and the first in NSW. The house is protected from bushfire ember attack with wall-mounted sprinklers as the home is only a few hundred metres from the Ku-ring-gai Chase National Park.
As a certified Passivhaus, mechanical ventilation with heat recovery (MVHR) is standard. The unit has an additional filter box which, during smoke events, allows for a HEPA grade filter to be added eliminating the majority of bushfire smoke particles.
The high-quality, airtight construction was delivered in just 3 days using a prefabricated panelised system from Carbonlite which eliminated the weather risks of wet framing locking in moisture behind the membrane layers.
Asquith PurePassiv was the first As-Built rated Green Star Home project in Australia.
