A building requires a supply of clean air to remove heating or cooling loads, and humidity or emission loads like odors and particles from buildingmaterials. A wide variety of impurities in indoor air influences the health and comfort of the occupants. Among the sources of these impurities, buildingproducts are of great significance, as they are not easy to remove, and occupants often have no say in the choice of building materials in apartments, offices,and public buildings. And it is precisely because of the emissions from users and building materials that rooms need clean air in the first place.There are different air distribution systems like ceiling-based mixing ventilation, wall- and infloor supply systems as mixing-displacement ventilation anddisplacement ventilation with low-velocity diffusers.Each of these systems is characterized by a different ventilation efficiency coefficient and in combination with the odor characteristics of typical emitters(building materials and people), a qualitative analysis is possible.In this paper an experimental and calculation analysis will show a comparison of different air distribution systems from the perspectives of indoor airquality and odor distribution. For different kinds of emission sources, a material curve for odor emissions will be prepared.The main question is whether low-emitting substances have the same distribution behaviour in a room with different air distribution systems. Which of thechosen supply systems is the best for good indoor air quality and why? The ability to predict odor emissions and their distribution would have a significantinfluence on the energy demand of buildings. The outside air volume flow could be adjusted according to need.
