Performance evaluation of kitchen hoods.

Kitchen hoods are frequently found in Belgian kitchens. Most of them have as only function intensive ventilation during certain cooking activities. It is expected that kitchen hoods with appropriate performances can also play an important role as devices for guaranteeing basic ventilation. The aims of the research can be summarized as follows: How do occupants evaluate the performance of existing kitchen hoods? What are the sound levels (dB(A)) in various locations in these dwellings due to the kitchen hood? What are the flow rate performances of old and new kitchen hoods in occupied dwellings and in the laboratory? What are the measured ventilation efficiencies in the laboratory?
