“…NASA conducted an "air and water purification experiment" as part of a lunar base plan in the early 1980s and was the first to explore the improvement of the indoor air quality (IAQ) through air-purifying plants (Hort et al, 2012;Inbathamizh, 2020). NASA scientists were interested in the Earth's self-cleaning ability, for which living plants were the solution (Berg et al, 2014;Wolverton and Nelson, 2020).…”

Due to hot desert weather, residents of the United Arab Emirates (UAE) spend 90% of their time indoors, and the interior environment of the newly built apartments with inappropriate material and ventilation is causing sick building syndrome (SBS), faster than in any other country. NASA studies on indoor air pollutants indicate that the usage of 15–18 air-purifying plants in 18–24 cm diameter containers can clean the air in an average 167.2 m2 house (approximately one plant per 9.2 m2). This study investigates the effect of three different types of air-purifying plants, Pachira aquatica, Ficus benjamina, and Aglaonema commutatum, in reducing volatile organic compounds (VOCs) and formaldehyde (CH2O) in hot desert climate. An experiment is performed in which the CH2O and VOCs concentrations are measured in two laboratory spaces (Room 1 and Room 2). Different volumes (5 and 10% of the laboratory volume) of target plants are installed in Room 1, whereas Room 2 is measured under the same conditions without plants for comparison. The results show that the greater the planting volume (10%), the greater is the reduction effect of each VOCs. In summer in hot desert climate, the initial concentration (800 µg/cm3) of CH2O and VOCs is higher, and the reduction amount is higher (534.5 µg/cm3) as well. The reduction amount of CH2O and toluene (C7H8) is particularly high. In the case of C7H8, the reduction amount (45.9 µg/cm3) is higher in summer with Aglaonema commutatum and Ficus benjamina. It is statistically proven that Ficus benjamina is most effective in reducing CH2O and C7H8 in an indoor space in hot desert climate. The findings of this study can serve as basic data for further improving the indoor air quality using only air-purifying plants in hot desert climate of the United Arab Emirates.

“…In fact, plants can remediate the quality of the polluted indoors in the form of the ability to extract contaminants from the environment. The application of decorative plants is important and recommended because of its ability to eliminate chemicals from the use of air fresheners and insect killers (29)(30)(31)(32).…”

The condition of the space environment as a result of the interaction of physical, chemical, and biological factors, in a complex way, can have acute and chronic effects on the physical and psychological health of the occupants. This was the incidence of sick building syndrome, and efforts to reduce and eliminate the syndrome were presented in this case study. The aim was to produce healthy indoor quality and sustainable use by its occupants. The methods used minimum Indonesian standards regarding procedures for planning the housing environment in urban areas. The analysis of changes in the indoor volume employed indoor height variables for a particular floor area to apply flexibility to various building layouts. The variability of changes in the pollutant exposure area and indoor air volume was expressed as a relative change. Setting indoor height was a significant determinant for maintaining healthy indoor air quality through diluting air against pollutants. An additional 0.5 m of room height could increase the air volume by 15%-20% greater than the increase in the pollutant area. It was an effective method both at the design and building renovation stages. The physical and thermal mitigation was generally performed at the building use stage. Some of the conducted approaches included air conditioning (AC), electric or manual ventilation, and chemical-phytotechnological mitigation indoors by adding chemicals to space. The methods of indoor depollution during the use of buildings are still necessary using physical and chemical-phytotechnological methods by placing decorative plants.
