PASSIVHAUS
High-Performance Homes Without Compromise
Homes designed for comfort, health, and ultra-low energy use — built for Tasmania’s climate.
What is Passivhaus?
Passivhaus is a performance-based building standard that dramatically reduces the energy needed to heat and cool a home. Instead of relying on mechanical systems, a Passivhaus building uses intelligent design, airtight construction, superior insulation, and high-performance windows to maintain a stable indoor temperature year-round.
Originally developed in Germany, Passivhaus is now used worldwide in homes, apartments, schools, and commercial buildings — across all climates.
Passivhaus (Passive House) is a world-leading building standard focused on energy efficiency, comfort, and indoor air quality.
Instead of relying on heavy heating and cooling, a Passivhaus is designed so the building itself does the work — using insulation, airtightness, high-performance windows, and ventilation to maintain a stable indoor climate year-round with minimal energy.
At Zanetto Builders, every Passivhaus is performance-modelled specifically for its site and climate.
Passivhaus homes deliver a completely different living experience:
• Consistent indoor temperatures
• Clean, filtered fresh air 24/7
• Ultra-low energy use
• Quiet, draft-free interiors
• Reduced condensation and mould risk
• Long-term durability and comfortThis is comfort you can feel — and performance you can measure.
Passivhaus is for people who:
• Want a healthier, smarter home
• Care about long-term quality and comfort
• Value sustainability and low running costs
• Are building in Tasmania’s challenging climate
• See their home as a future-proof investmentIt’s for clients who want more than a standard build.
A Passivhaus usually costs more upfront than a standard home — because it’s built to a much higher performance level.
That investment goes into:
• Higher insulation levels
• Premium windows and doors
• Airtight construction detailing
• Mechanical ventilation with heat recovery (MVHR)
• Performance modelling and testingBut over time, lower energy bills, durability, and comfort make it a smarter long-term choice.
Yes — but very little.
Because the home is so well insulated and airtight, it holds heat in winter and stays cool in summer. Most Passivhaus homes only need a small, simple system — often integrated into the ventilation setup — to fine-tune the temperature.
It’s for clients who want more than a standard build.
Dramatically lower than a standard home.
A well-built Passivhaus can use up to 80–90% less energy for heating and cooling compared to conventional construction.
That means:
• Lower power bills
• Less exposure to energy price rises
• More predictable running costs
• A home that pays you back over timeZanetto Builders are Tasmania’s leaders in high-performance and Passivhaus construction.
