Hybrid ventilation systems

This paper presents a new concept of ventilation system for residential building, based on a hybrid ventilation system, mainly control by weather conditions and IAQ sensors to optimize exhaust airflows rates, for the purpose of improving global building energy performance and improving the quality of life of the occupiers.

There are many ventilation and air conditioning systems, having their own set of advantages, disadvantages and applications. Inadequate control on ventilation rate for the case of natural ventilation system can lead to indoor air quality problems or excessive energy loss, while mechanical system is often expensive for the installation, operational and maintenance costs.
