A laboratory investigation has been made in a modern Swedish bathroom continuously ventilated by an exhaust fan. The tests consisted of measurements of the humidity, temperature and local mean-age after a standard shower. The measurements were mainly made in a non-heated installation.
A commercially available humidity controlled natural ventilation system (Aereco) has been installed in the framework of a CEC demonstration project in 3 apartment buildings in France, the Netherlands and in Belgium. An extensive monitoring campaign in reference apartments and humidity controlled apartments during the 2 previous winters allowed a detailed analysis of various ventilation related parameters. Special attention is given to the evaluation of the humidity control on the performances.
