The main problem of closed rooms is air pollution with chemical compounds, dust, anthropotoxins and pathogens. Solving this problem with the help of technical and engineering technologies is not always effective, since it requires a lot of time and significant capital investments. The technology of phytodesign by phytoncidal plants is proposed. The purpose of the work is to optimize the air environment by an example of the winter garden in Kiev National University of Construction and Architecture using phytodesign by phytoncidal plants. Objectives of the work: to examine the assortment of plants in the winter garden; to assess whether the number of plants is sufficient for sanitation of the air environment of the premises with an area of ​​930 m2; analyze the shortcomings of the range of phytoncidal plants; to develop proposals for the phytodesign of a winter garden to improve the quality of the air environment. It was found that the existing number of phytoncidal plants (18 pieces) for effective sanitation of the air in the investigated room is insufficient. Their decorative effect is reduced due to some disadvantages of care. It’s one of the reasons for a decrease in the growth of vegetative mass and the production of phytoncides. For effective air sanitation of the area of the investigated room, 310 specimens of large-sized phytoncidal plants are required. To expand the assortment, the following phytoncidal species are offered: Aglaonema, Anthúrium Aspidistra elatior, Begonia Chlorophytum, Dracena marginata, Ficus benjamina Wiandi, Hedera, Kalanchoe, Nolina, Philodendron, Spatifillum, Scindapsus, Sansevieria, Eucevieriaceae, plants of the families Euphorbiaceae, Orchidáceae, Bromeliaceae. Green phytoncidal zones can also be expanded by introducing "green" structures.

Sick Building

The 21st century is the era of civilization transformation from the industrial society towards the information society. One of the main features of the information society is spending most of their time to work in a building with the aids of artificial ventilation. However, most of these societies are evolving a mindset in which the job done in the space of an office building is a job that does not have risks as well as the most safe and comfortable working environment from negative influences. In fact, previous studies have shown that the quality of air in a space is a significant factor that can influence the effectiveness of the quality of work. These include declining productivity and damages to material and equipment and also impact on the health of workers. This study discusses the effects of indoor air pollution on human health in the workplace environment. Therefore, this paper also discusses the contaminants in the air that contribute to sick building syndrome. The study found that indoor air pollution is a significant adverse effect on the health of workers in the building.

Indoor And Outdoor

An average person spends most of his time indoors and the quality of indoor air affects his performance and well-being. This justifies the study of indoor air pollution for the development of working and living environments which are comfortable and safe. As a part of a larger program to study traffic-generated air pollution in the vicinity of streets, a simultaneous indoor/outdoor sampling program was carried out at three sites in the city of Zurich, Switzerland. Parameters included CO, NO, NO2 and HCHO. The results show the direct relationship between indoor and outdoor concentrations of CO, NO and NO2. HCHO concentrations were found to be substantially higher indoors than ourdoors thus supporting the hypothesis that HCHO source could be in the buildings themselves. The importance of indoor air is emphasized, and the interplay of indoor and outdoor air pollution is demonstrated.

Two Cities

This study examined the indoor air quality of restaurants in two cities with universities, one smoke-free (n=15) and one that allowed smoking (n=17). Results indicated that restaurants protected by smoke-free ordinance had significantly (p=.036) lower levels of particulate matter (13.10±10.33 ug/m3) compared to restaurants which allowed smoking (130.72±212.64 ug/m3). Mean particulate matter within smoking-allowed restaurants was caused by as few as three cigarettes being smoked at one time. Based on the EPA Air Quality Index, 70.6% of smoking-allowed restaurants yielded an unhealthy classification compared to only 6.7% of smoke-free restaurants (p=.005). Smoke-free ordinances provide effective protection from indoor air pollution.

The Impact

Considering the alarming rise in the rate of asthma and respiratory diseases among school children, it is of great importance to investigate all probable causes. Outside of the home, children spend most of their time in school. Many studies have researched the indoor environmental quality of primary and secondary school buildings to determine the exposure of school children to indoor air pollution. However, studies of very young children in nurseries are scarce. Unlike at elementary schools or universities, children in nurseries are more vulnerable due to their physiology, inability to articulate discomfort and to adapt their behaviour to avoid exposures. This article reviews current studies on the indoor environment in nurseries. It summarizes air pollution levels and related environmental and behavioural factors in nurseries that have been reported in the literature. Additionally, exposure to indoor air pollution and related potential health outcomes are examined. This review concludes that indoor air pollution in nurseries often exceeds current guidelines, and designers and policymakers should be made aware of the impact on the health and wellbeing of children in nurseries. Proper interventions and guidelines should be considered to create a healthy indoor environment for nursery children. Practical application: Previous IAQ assessments have mainly focused on indoor temperatures and CO2 levels. Data on comprehensive monitoring (including PMs, NO2, O3 and other pollutants) of indoor air quality of nurseries are scarce. Particularly in the UK, studies about indoor air quality in nurseries have not been founded. This paper categorized relevant articles according to the focus of the study, to provide evidence to a better understanding of current indoor air quality in nursery environments.
