LoginThree hybrid ventilation concepts are described: alternate use of natural and mechanical ventilation; fan assisted natural ventilation; stack and wind supported mechanical ventilation. The concepts described comprise some newly constructed rather advanced buildings but also some existing more traditional type buildings. All buildings with hybrid systems up till now are far from what might be the optimum solution. There is a knowledge gap especially on dimensioning and control of hybrid ventilation systems. The remaining challenges and unsolved problems for hybrid ventilation are briefly described.
