How does ventilation work in an Ekodome?
A breakdown of the vent options, airflow methods, and mechanical systems you can use to keep your dome comfortable year-round.
Ekodomes use a passive ventilation system that relies on natural airflow rather than mechanical equipment. The principle is straightforward: cool, fresh air comes in from the lower part of the dome, and warm, stale air escapes from the upper part. This creates a steady, natural circulation that helps regulate temperature and humidity inside the structure.
How Passive Ventilation Works
1. Fresh air comes in through the lower grid vents.
These vents sit close to the base of the dome. They pull cooler outside air into the structure.
2. Warm air rises naturally to the top of the dome.
As the interior warms up, heat and humidity move upward.
3. Stale air exits through the circular roof vents.
Roof vents are placed high on the dome to release rising warm air.
Together, these two vent types create a consistent airflow loop that stabilizes the interior environment without electricity.
Passive Vent Options
You can add these during your dome configuration:
Grid Vents
Bring fresh air into the dome. Help prevent moisture buildup. Essential for the airflow cycle.
Circular Roof Vents
Release heat, humidity, and stale air. Support passive cooling. Improve overall comfort.
Operable Windows
Work together with vents to create cross-ventilation and help regulate indoor humidity and temperature.
Mechanical Ventilation (Optional)
Many clients add mechanical ventilation for full-time living or high-humidity regions:
• exhaust fans
• intake fans
• HRV/ERV systems
• dehumidifiers
These connect through dedicated vent openings.
