A detailed statistical analysis of window use and its effect on the ventilation rate in 2400 Belgian social houses.

A large inquiry campaign began in 1985 on 100 social housing estates and 2,334 families were visited. The housing estates were selected according to their age, location, type of building (dwelling/apartment) and heating system. The main purpose of this paper is to explore the data received concerning window use in order to find the effect of the inhabitants on the ventilation rate. The summertime and wintertime situation was analysed and differences between individual dwellings and apartments were also investigated.

Effect of instructions to inhabitants on their behaviour.

Within the framework of the International Energy flgency (IEA) Annex VIII , "Inhabitants Behaviour with Regard to Ventilation" an investigation has been carried out on the use of windows in an apartment building in Schiedam. The measurements have been done by the TNO Division of Technology for Society.
