Rising pandemics and epidemics of infectious diseases in recent decades, WHO warnings about the main causes of epidemics in buildings - closed space without properventilation, high population density, spaces with the possibility of physical contact - experts' attention to the parameters of the spreader Contaminants are directed indoors.The World Health Organization estimates that the concentration of pollutants in the indoor environment of buildings can be up to five times higher than in the open.Pollutants that enter the body through inhalation, contact and ingestion; They can be harmful, toxic, dangerous and / or deadly. Having a healthy shelf life now depends onremoving or reducing the pollutants inside the buildings. Therefore, it is necessary to identify the sources of pollutant emissions, evaluate and analyze the amount and level of pollutants, to identify the effects of exposure to any pollutant on humans. Reduced injuries, poisonings, hazards and deaths from exposure to indoor pollutants.Research shows that identifying the sources of pollutant emissions, eliminating or reducing them in the indoor environment of buildings does not seem to be easy because it is difficult to separate the effective environmental parameters, resource constraints, material processing technology, operator skills and implementation methods. It requires long-term planning, investment in infrastructure and education. Finally, informing users and encouraging them to reduce their presence in contaminated environments (especially during the outbreak of infectious diseases) is the fastest way to reduce environmental damage. In the field of architecture, the method of design, selection of materials and executive details, the method of construction and maintenance of buildings to improve the quality of space should be reviewed and upgraded. Architectural changes and metamorphosis in the way space is organized can be very extensive, but in this discourse the context of design is considered; Design of open and semi-open spaces suitable for operation, use of natural passive elements to provide conditions of outdoor comfort, exterior shell dynamics and interior functions are recommended.
