About Hybrid Ventilation
Hybrid ventilation incorporates natural ventilation with traditional mechanical systems, all while reducing energy consumption, providing a healthier indoor climate, and reducing CO2 emissions.See our control systems
What is Hybrid Ventilation?
Mixed mode ventilation or hybrid ventilation is a relatively new concept that is a sustainable and cost-effective way to provide thermal comfort to occupants by regulating the indoor temperature. This ventilation strategy not only offers a means of indoor climate control, but also enhances indoor air quality by lowering CO2 levels, creating a healthier indoor climate, and improving occupant productivity.
Mixed mode ventilation systems combine all the best features of natural ventilation by controlling building openings automatically and intelligently with window actuators and a mechanical system.
Hybrid ventilation or Mixed Mode Ventilation?
These terms are used interchangeably to mean the same thing! So, the same principles and benefits that we describe about mixed mode ventilation are the same for hybrid ventilation.
How do hybrid ventilation systems work?
Hybrid ventilation systems reduce energy consumption through the reduction of mechanical fan use and, in some cases, the cooling demands. By using key natural ventilation strategies to ventilate during the day or night (night cooling), mixed mode ventilation reduces the use of mechanical systems and possibly the size of the system. Like natural ventilation systems, hybrid ventilation systems utilize sensors to monitor indoor temperature, CO2 levels, and humidity, as well as outdoor conditions. Based on this data, the system will automatically either chose natural ventilation or mechanical ventilation depending on which system is the most optimal to use. The system will then switch back to the natural ventilation strategies when appropriate. For example, if the weather is too cold, too rainy, or too hot, the mixed mode ventilation system adjusts the building openings appropriately and communicates with the mechanical ventilation system to optimize the indoor environment. The system, then, takes a holistic approach to ensure occupant comfort and indoor climate health for a high-performance building.
