Cafes are specific places with increasing popularity these days. However, the spaces used mainly for meetings, work or studying have not been yet explored in detail from the microclimate point of view, although suboptimal microclimatic conditions can have a negative effect not only on employees but also on customers. The bachelor thesis deals with an evaluation of air quality in coffee shops and juxtaposes its findings with the legislation that defines beneficial conditions for the particular environment. The aim of the thesis is to determine whether the values of temperature, relative moisture including the concentration of PM2,5 and carbon dioxide, based on an example of three specific coffee shops situated in the center of Prague, correspond with the acceptable standard quotes stipulated by the law. To that end, the author explores three assumptions: 1) the selected spaces are not strictly controlled by the Public Health Authority in comparison for instance with hospitals and therefore the recorded values do not correspond with the regulations, 2) the number of people worsens the CO2 values and 3) coffee shops with an entrance facing a busy street show a higher concentration of PM2,5. The results were achieved by experimental measuring in Winter months. The theoretical part defines the concept...
