Passive Ventilation Systems for Your Ekodome
Ekodome offers passive ventilation systems designed to regulate airflow, reduce condensation, and improve comfort inside your geodesic dome, whether you're using it as a dome greenhouse, eco dome, or geodesic dome house.
Passive vents work by harnessing natural forces—like rising hot air and wind—to circulate fresh air throughout your structure without electricity or mechanical systems.
Types of Passive Vents We Offer
We currently offer three types of passive vents:
-
Circular Roof Vents – Installed at the top of the dome to release hot air
-
Grid Vents – Installed near the base to draw in cool air
-
Operable Windows – Used in combination with vents for balanced cross-ventilation
You can add these passive vents during the dome kit configuration process.
How Many Passive Vents Do You Need?
The number of passive vents depends on your dome model, location, climate, usage, number of windows, and the dome frame type. Here's a quick guide:

Using HVAC or Fireplace Systems?
If your Ekodome geodesic dome kit will include HVAC, a fan, or a fireplace, your need for passive vents may be reduced or eliminated entirely.
