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.
Keynote address of the 7th AIVC Conference. Address aims 1) to set an energy efficiency context for research into air infiltration; 2) to summarise current research themes; 3) to suggest aims for research in air infiltration and occupant behaviour.
The paper describes the main results from a research project performed by "The Mobile Laboratory of Indoor Climate Measurements" one of the five mobile laboratories of the Institute. The aim of the project was to investigate if undesirable consequences occurred in the indoor climate when using an energy saving method consisting of reducing the mechanical exhaust from the "wet rooms" to app. 40 per cent of the normal performance during 12 hours of day and night.
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. They started in November 1984 and stopped in May 1986, Three inquiries and diaries have been set up in the tno heating seasons and the summer period to get additional information from the dwellers, In the 6th AIC conference [1] paper 20 dealt with the first heating season of this project.
