ABSTRACT
Outdoor air quality, buildingmaterials, HVAC systems and people activity are important factors
in human exposition of polluted indoor air. The degree of signification varies in dependence
on pollution character and its sources. Buildings eliminate significantly people exposition of
outdoor pollutants, but on the other hand, buildings are significant source of indoor pollution.
The contamination of indoor air is largely from the use of gas for heating and cooking
appliances. A comprehensive analysis of indoor air pollution by nitrogen oxides shows that the
extent of indoor air pollution and consequent exposure varies as a result of many factors mainly
the differing distribution of appliances and their level of use. This study aims to formulate a
mathematical model for the production of nitrogen oxides indoors. The physical processes that
determine the concentrations of indoor nitrogen oxides as a function of outdoor concentrations,
indoor emission rates and building characteristics have been mathematically described. The
mathematical model developed has been parameterized for typical Slovak residences. The
modeling of the occurrence of indoor nitrogen oxides and verification of the model is presented
in this paper.
