Patterns in ventilating and airing behaviour in relatively well-insulated newly-built terraced houses. Het ventilatie- en luchtgedrag in relatief goed getsoleerde nieuwbouwwoningen motieven en consequenties voor het energieverbruik.

Reports a case study dealing with the relation between ventilating and airing behaviour and the outside climate. Also the significance of other variables such as preferences with respect to the indoor climate are considered. Wind speed is found to correlate, but outside temperature (varying from -3 to +9 degrees C) does not correlate with the length of time the windows in the bedrooms and bathrooms are opened. Rainfall and sunshine also seem to have some influence. The main reasons for airing are that the bedrooms are too warm and not fresh. On an average the windows of the bedroom, if used for sleeping, were opened 6 hours a day. 70% of the respondents opened these windows more than 2 hours a day. More field studies into condensation and moisture problems are recommended.
