Certified Passive House

Certified Passive House Ventilation & Dehumidification

Passive House construction demands a higher level of precision, planning, and performance than conventional residential building.

Ventilation is not simply an optional upgrade in a Passive House. It is a critical part of the building’s comfort, energy efficiency, indoor air quality, and overall performance strategy.

Zenith Ventilation specialises in the supply and installation of certified Passive House ventilation systems and components for residential Passive House and high-performance building projects.

Why It Matters

Passive House projects need carefully planned ventilation

Passive House homes are highly insulated and extremely airtight. Without properly designed mechanical ventilation and humidity control, these homes can trap moisture, indoor pollutants, VOCs, cooking odours, excess humidity, and stale air.

Zenith works closely with Passive House designers, certifiers, builders, architects, and homeowners to deliver ventilation and humidity control systems that align with Passive House performance requirements and airtight construction practices.

  • The Challenge

    Passive House homes are extremely airtight, so moisture, stale air, and indoor pollutants need to be carefully managed.

  • The Solution

    Zenith designs and installs certified Passive House ventilation systems with integrated humidity control where required.

  • The Outcome

    A healthier, quieter, more comfortable, and more energy-efficient home with balanced fresh air and long-term building protection.

What your Passive House gains from better ventilation

Integrated ventilation and dehumidification systems help provide fresh filtered air, controlled humidity, balanced ventilation, heat recovery, improved indoor air quality, and increased occupant comfort.

  • Fresh filtered air
  • Controlled humidity levels
  • Balanced ventilation
  • Heat recovery
  • Improved indoor air quality
  • Long-term building protection

A complete Passive House environmental control solution

While heat recovery ventilation provides continuous fresh air and balanced ventilation, Australian conditions can present additional humidity challenges. In Sydney, coastal regions, and northern climates, outside air can remain highly humid for extended periods.

For this reason, many certified Passive House homes in humid Australian climates incorporate dedicated whole-home dehumidification as part of the overall environmental control strategy.

  • Heat Recovery Ventilation

    Continuous fresh filtered air with heat recovery for comfort, energy efficiency, and balanced ventilation.

  • Whole-Home Dehumidification

    Dedicated humidity control for Australian Passive House conditions where ventilation alone may not be enough.

  • Make-Up Air Systems

    Controlled replacement air designed to integrate with airtight, high-performance homes.

  • Airtight Range Hood Solutions

    Airtight kitchen ventilation solutions that help protect the building envelope and support Passive House performance.

Tailored Design

Designed specifically for the project

Passive House projects require more than standard HVAC installation practices. Ventilation installations must be carefully planned to avoid unnecessary penetrations and protect the integrity of the building envelope.

  • Building design
  • Airflow requirements
  • Energy efficiency targets
  • Humidity control requirements
  • Acoustic performance
  • Airtightness requirements
  • Certification objectives
  • Blower door considerations
