Analysis of hydrid ventilation perfomance in France

Agency Annex 35 “Hybrid Ventilation in New and Retrofitted Office Buildings”. It consisted in modeling a typical classroom and in predicting performance of a hybrid ventilation system compared to two traditional mechanical systems: a mechanical exhaust ventilation system and a balanced ventilation system. The hybrid system considered here was a fan assisted natural ventilation with a temperature and CO2 based control strategy. The study of this specific hybrid ventilation system was performed for several cities in France and predicted its potential in terms of thermal comfort, CO2 concentration and energy consumption given the climate in France.
