Australia’s first Passive House to achieve the highest bushfire rating has been built in New South Wales’ Blue Mountains.
The house meets the development requirements for the highest bushfire risk rating — Bushfire Attack Level Flame Zone (BAL-FZ). It has a complex system of remotely controlled electric shutters, fire resistant external cladding and fluid ventilation, balancing energy efficiency with strict fire safety standards. The home also features triple glazed windows and climate-specific insulation.
The calculated daily cost of powering the house is $3.80 per day, due to the home’s sophisticated ventilation system which maintains a steady internal temperature year round. Construction costs for the house were 22 per cent higher than a standard build.
