ventilation rate

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.

Energy conservation - side effects of reduced ventilation rates and increased insulation.

Notes field evidence of increased condensation in houses with reduced ventilation and increased thermal insulation installed to conserve energy. Treats the possible long term effects. Gives advice on taking into account the whole package of heating and ventilation of the property when energy conservation measures are being contemplated.

The use of passive ventilation systems for condensation control in dwellings and their effect upon energy consumption.

The need for reduced energy consumption has led to an overall decrease of air infiltration rates in buildings. particularly in dwellings. Unfortunately. this has given rise to a significant number of problems involving condensation. with resulting damage to the structure and contents of affected buildings. Various means of condensation control are available. The use of a passive ventilation system to achieve this aim has several attractions. not the least of which is that the occupants of houses fitted with such a system need little. if any, knowledge of the principles involved.

Ventilation and indoor air quality in new Norwegian dwellings.

SINTEF, The Foundation for Scienti f ic and Industrial Research at the Norwegian Institute of Technology, has monitored a number of experimental low-energy houses, and also undertaken measurements in some other houses to establish the energy consumption, air tightness, ventilation rates etc. Some of the experimental houses are extremely air tight. In connection with these measurements we have made some observations on the occupants behavior related to ventilation, and their satisfaction with the ventilation system.
