Describes the "olfbar", first presented at the "Healthy Buildings '88" conference. At the bar, different qualities of air may be perceived. It is intended to demonstrate that air polluted by materials or components in buildings may often not be acceptable for human beings. These materials and components, ignored in ventilation standards all over the world, pollute the indoor air and make air stale, stuffy and irritating.
An analysis of the important factors for comfort in indoor climate is given. For the thermal complex, the results from calculations of the energy balance model MEMI are used to quantify the effects of the single meteorological parameters on occupants in indoor climate. The quantifications show that besides the air temperature, the mean radiation temperature and the air velocity, especially at very low levels, are also quite decisive for the occupant's mean skin temperature which is used as a measure for comfort.
