Passive House is often noted as being attainable by those willing to pay a steep cost premiums for the design and construction of a project.
If proof is required that building a comfortable, highly efficient Passive House is possible, that goes beyond the minimum energy efficiency compliance and uses construction techniques not too dissimilar to those we are accustomed too, then look no further than the leafy suburbs of Melbourne.
Sitting on an ideally oriented block in Brighton East, the single level Caramar Passivhaus has a compact floor plan with three bedrooms and a north-facing openplan living area.
“This house is designed to operate perfectly well without any interventions. You can have fresh air inside all the time without anybody opening or closing doors and windows,” explains Clare Perry, Passive House Consultant of the project. “But you get more efficiency if you do ventilate passively as well.” The HRV system is sufficient to vent stale air so no exhaust fans are required in bathrooms, laundry or kitchen, which avoids penetrations of the thermal envelope.
