One of the tasks defined in the basic principles of sustainable building construction is to ensure a quality indoor environment and the health and wellbeing of the building’s users. Especially in the current epidemiological period, people spend more than 90% of their time indoors. In almost every indoor environment (IE), there is a certain number of ornamental houseplants. In most cases, these are ornamental plants with leaves or flowers. These plants give us aesthetic impressions and improve the well-being of building users. Integration of these vegetation elements into building interiors can lead to a decrease in the incidence of Sick Building Syndrome (SBS) and Building-Related Illness (BRI). Plants can improve indoor air quality (IAQ). Although plants are a source of moisture, take up Carbon Dioxide (CO2) and release O2 through light-dependent photosynthesis, and effective filters to remove pollutants (volatile organic compounds) and improve indoor air quality, specific types of indoor plants are very often selected only by visual and aesthetic perception.
