Abstract

The odor microclimate is formed by gaseous airborne components perceived either as an unpleasant smell or as a pleasant smell. Smells enter the building interior partly from outdoors (exhaust fumes - flower fragrance) and partly from indoors (building materials, smoking cigarettes - cosmetics, dishes). They affect the human organism through the olfactory center which is connected to the part of brain that is responsible for controlling people's emotions and sexual feelings: smells therefore participate to a high level in mood formation. Sweet smells have a positive impact on human feelings and on human performance. Criteria for odor microclimate appraisal are presented together with ways of improving the odor microclimate (by stopping odors from spreading within a building, ventilation, air filtration, odor removal by plants, deodorization, etc.), including so-called AIR DESIGN.

Highlights

  • The odor microclimate is formed by gaseous airborne components perceived either as an unpleasant smell or as a pleasant smell

  • An optimum odor microclimate can be ensured by suitable changes in (a) the source of odors, and (b) the transfer field between the source and the exposed subject

  • Waste baling presses are awailable for home kitchens

Summary

Changes in the source of odors

If possible, removal of the source of odors, is the most effective way: Construction materials that do not release an odor, and production technologies without odor sources should be preferred. Two examples of effective ways are quick setting coatings and waste baling presses. Quick setting coatings were developed in France. They consist of a great number of low-molecular compounds and of so-called photo-initiators, which, when radiated by UV rays, rapidly (within a second) change low-molecular compounds into high-molecular compounds. Natural materials are preferred for wood preservation, especially beeswax applied directly to cleaned wood. Waste baling presses are awailable for home kitchens. A balong press can from part of a kitchen furniture suite (Fig. 1). Any odors, or microbe release from the waste is avoided
