Annex VIII is a two year task sharing project, started offically in 1984. Although some research had already been done on the problem of inhabitant's behaviour with regard to ventilation, none had gone so far as to access whether and how the ventilation behaviour can be modified in order to save energy and by taking into account the conflicting requirements, energy conservation and adequate indoor air quality.
By means of interviews this document describes occupants' window opening behaviour and draws from this certain sometimes surprising information about their motivations.
An abridged version of the study carried out under the auspices of the Federal Office of Energy by the Institute for Building Research of the Swiss Federal Institute of Technology, Zurich.
During winter periods in four types of newly built terraced dwellings and in apartments of a flatbuilding,the daily behaviour and motivations of the inhabitants with respect to airing and ventilation have been studied. In total the information was obtained from 279 households. A combination of verbal interviews, diaries and technical measurements are used as methods of investigation. On basis of the findings,calculations can be made about air flows in occupied dwellings.
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.
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.
