Definition of Hybrid Ventilation
Hybrid Ventilation is a two-mode system which is controlled to minimize the energy consumption while maintaining acceptable indoor air quality and thermal comfort. The two modes refer to natural and mechanical driving forces.


Principles of Hybrid Ventilation
1. Natural and mechanical ventilation
This approach is based on two fully autonomous systems. The control strategy either switches between systems or runs both in parallel but for different tasks. An example is a system that uses natural ventilation in mid-season and mechanical ventilation in summer and/or winter. This approach is also used by a system which provides mechanical ventilation in occupied hours and natural ventilation for night cooling.

2. Fan-assisted natural ventilation
This approach uses natural ventilation combined with an extract or supply fan. During periods of peak demand or when the natural driving forces are reduced, pressure differences can be enhanced by fan assistance.

3. Stack and wind-assisted mechanical ventilation
In this approach a mechanical ventilation system optimizes use of natural driving forces. It is used in systems with small pressure losses where natural driving forces can contribute significantly to the pressures needed.
