Formaldehyde is a typical indoor air pollutant that has numerous adverse health problems in modern living conditions. Phytoremediation that use plants to remove contaminants from polluted media can be applied to improve indoor air quality. Two sets of experiments; 1) two rooms in newly built auditorium and 2) a bed room in 2-year-old apartment; were performed to investigate plant effects on indoor formaldehyde concentration. It was observed from the experiments that plant can help decontaminating formaldehyde at low concentration level (0.1 ppm) but the effects decreased considerably at hish concentration (1ppm). The purification effects of indoor plant also showed the periodic pattern due to its physiological activity. More purification was observed as increasing plant density in the bed room but the formaldehyde concentration returned the original concentration level in two days after removing plants. It was suggested from the results that air purification using plants is an effective means of reduction on indoor formaldehyde level, though, reduction of source is highly desirable when the concentration level is high. The results also suggest that introducing supplementary purifying aids and/or efficient ventilation could be considered due to periodic removal pattern of plant.

Indoor gardens tailored to suit individual tastes offer a place to enjoy plants and to relax to city dwellers to relieve stress from city life. However, there are technical issues to build such indoor gardens. To offer solutions to technical issues, this study aims to analyze development phases of indoor garden-related technologies by studying available patents in detail. Also, the study aims to understand current status and future direction of technologies by examining technological trends for introduction of indoor gardens. Brainstorming method was used to understand technology trends and as a result, two groups were identified for technical features of indoor gardens: indoor greening technology and rest area for users. An analysis on selected patents showed that the number of patents increased until 2010 and declined gradually afterwards. Korea ranked the highest in the number of patents grant followed by USA, Japan and Europe. Similar order was observed with the number of patents granted by nationality of applicants. The number of patents granted by nationality was the highest for Korean nationals. For indoor greening technologies, patents related to structure from 2007 were mostly concentrated in the areas of irrigation control and environment control for plants and vegetation. For rest area related technologies, patent related to structure showed a repetitive pattern of increasing and decreasing, but overall, on downtrend. For further development and dissemination of indoor gardening technology, more R&D work is needed with focus on environmental control technology for designing suitable environment for both human and plant.

This survey is to investigate the effect of plants and waterscape facilities on the thermal indoor environment and to provide basic data for proper plant cultivation to enhance indoor landscape. The survey of the measure of comfort on the indoor environment for the residents of Taegu shows that the measure of comfort on the thermal-environment, which consist of temperature and humidity, has more negative responses than the measure on lighting . are . sound environment, which consists of air freshness, lighting condition and sound environment. The experiments on the effect of the amount of leaves and the distance of plants on the indoor thermal-environment are made. The experimental results illustrate that, as the capacity of a plant becomes greater and the distance from the plant shorter, the falling effect of temperature and the rising effect of humidity on the top of the plant are taken higher than on the side of the plant. When the same amount of leaves is set up, the distance range of the rising effect of humidity becomes wider than that of the falling effect of temperature. The investigation of the effect of waterscape facilities on the indoor thermal-environment shows that temperature and humidity of the space with installed waterscape facilities are lower and higher than without facilities, respectively.

With architectural technology, a building has been a far dense and close. So the thermal environment of the building has become pleasant, but the quality of indoor air has been degraded. Using synthetic products for construction materials and furniture indoors escalates the concentration of volatile organic compounds(VOCs) at indoor air, threatening the health of the residents. To reduce the concentration of volatile organic compounds at indoor air, many methods are designed, and of late, concern has been increased about the effect of air purification using air purifying plants. Field measurements were performed using Aglaonema brevispathum, Pachira aquatica and Ficus benjamiana, which were verified as air-purifying plants by NASA. The effect of reducing the concentration of air contaminants by plant studied in a full scale mock-up model. The variations of concentration of Benzene, Toluene, Ethylbenzene and Formaldehyde were monitored. In most cases, the effect was excellent in Toluene and formaldehyde in summer.

In this study, we compared efficiency of different aquatic plants in removing indoor pollutants and examined their potential to purify indoor air. Two liter of water in chamber was used as the control, while the other chambers containing water lettuce (Pistia stratiotes), water hyacinth (Eichhornia crassipes), and water coin (Hydrocotyle umbellata) were used as treatment groups. Temperatures inside all the chambers were maintained between 20 ℃ and 23 ℃. Humidity in the chambers with aquatic plants increased by 30% and 50% control respectively. The removal of formaldehyde per unit leaf area was examined in each aquatic plant. It turned out that water hyacinth removed the highest amount of formaldehyde, followed by water lettuce and water coin. Both water hyacinth and water lettuce increased the amount of removal of formaldehyde until the end of the experiment. In the case of airborne dust (PM 10) and fine dust (PM 2.5), water coin, which had the highest number of leaves, removed more PM 10 and PM 2.5 than the other aquatic plants, with statistically significant difference. In addition, both water coin and water hyacinth smoothly opened and closed stomata before and after the experiment. Consequently, as the aquatic plants were effective in controlling humidity and removing pollutants, they can be used as air purifying plants.

Background and objective: This study was conducted to understand urban residents' perception of indoor plants in order to assist in the preparation of guidelines for growing plants indoors. Methods: Questionnaires were distributed to urban residents currently growing plants or with experience of growing plants. The data of 247 respondents were subjected to analysis to assess their level of interest and ability with regard to growing plants, and their recognition of the selection and function of plants. Results: Respondents showed high interest in growing plants at a level of 6.77, but their ability was moderate. This suggests that information regarding plant maintenance should be provided to urban residents. They recognized the function of plants for improving the environment as important, and expected that indoor plants would improve their mood and visual experience. Satisfaction with growing plants was high from an emotional perspective. They recognized that the function of air purification function was important even if the actual performance or effect was not great. This indicates that the function of air purification should be emphasized more. As the result of the IPA, plants should be selected in consideration of morphological characteristics such as leaf, flower and fruit, and continuously managed to maintain their characteristics. Since the performance of pots was less satisfactory compared to their importance, they should be selected so that they harmonize better with plants and are of the appropriate size to fit the space. The type of plants is an important factor in plant selection in order to perform an environmental function, and the flower color and pot size are important in terms of aesthetics and healing. Conclusion: When horticulture information on indoor plants is provided to urban residents, first, it should be provided to satisfy the functions of the plants required by urban residents and in order to promote and maintain the proper growth of plants. Second, various contents that utilize components should be developed to achieve plant function so that resident can determine the function of plants and select the type, quantity, and shape of plants to achieve the desired function.
