States that ventilation needs can be identified from a study of people's behaviour. Reports results of regular systematic observations of open windows in a group of scottish houses which confirmed earlier work in Britain. Finds that the number of open windows is a direct function of outdoor temperature or moisture content and was also influenced by air speed with a smaller number of windows being opened in windy weather. Large families opened their windows more frequently than small families. Suggests that moisture control may be the main motivation for opening windows.
