# 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.
