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.
The Energy Letter concept was introduced in autumn 1989 in a move to provide home-owners with a statistical breakdown of their water and electricity consumption. Customers learn about their energy use and get an almost immediate response on Home with direct electrical heating efficiency measures applied. As a result of the project, the average amount of energy used per customer was reduced by 2,400 kWh per year. The Energy Letter does not require any investment cost.
