In-situ performances measurement of an innovative hybrid ventilation system in collective housing retrofitting

To get closer from comfort and energy levels of new buildings conciliating economical viability for the big retrofitting market : the challenge opens the way to the most innovative ventilation systems. In this context was born a new hybrid ventilation system mixing demand-controlled components and low pressure assistance fan. HR-VENT is an exceptional large-scale monitoring launched in France in the suburb of Paris in order to measure the effectiveness of this new system, as well as to improve the knowledge on the hybrid and standard natural ventilation. This monitoring, lead in collaboration with French corporate partners, will favour the development of new solutions for the ventilation of residential buildings.
