Mechanical Ventilation in High Performance Homes: Why Fresh Air Matters

One of the most important systems in a high-performance home is something you don’t always see — mechanical ventilation.

While insulation and airtightness keep your home sealed and efficient, ventilation ensures the air inside stays fresh, healthy, and free from moisture build-up.

High performance homes are built to reduce long-term energy use

Why Ventilation Matters

In a tightly sealed home, air doesn’t naturally circulate as easily. Without proper ventilation, this can lead to:

• Condensation

• Mould growth

• Stale indoor air

• Poor air quality

How Mechanical Ventilation Works

Mechanical ventilation systems:

• Draw in fresh outdoor air

• Filter it for dust and allergens

• Distribute it throughout the home

• Remove stale, moist air
