This paper reports on the findings from two extensive laboratory studies of ventilation of bathrooms of different sizes and layout of ventilation. The ventilation flow rates were varied. Moisture production were due to laundering and shower baths. In one of the studies the bathroom was provided with a drying cabinet. The extract air was forced to pass through the drying cabinet which was connected to the extract ventilation system of the house by a duct running from the cabinet to the extract air terminal device.
Kitchen hoods play an essential role in the ventilation of kitchens. This paper describes activities carried out at the Belgian Building Research Institute with respect tothe determination of kitchen hood efficiencies. The linkwith European standardization is also described.
