Reviewing the Effect of Indoor Living Walls on Air Quality, Energy Consumption in Different Climates

Living Walls and greenery systems importance is increasing as a sustainable building design elements to enhance environmental building’s impact. Numerous amounts of studies have demonstrated that outdoor greening, such as trees and landscaped areas can reduce a building’s energy consumption indirectly, as well as studies that have been conducted on the impact of indoor vegetation on energy use and air quality. Indoor vegetation and planting decrease the carbon dioxide (CO2) concentration through absorbing carbon dioxide (CO2) and releasing oxygen (O2) where energy expenditures get reduced. Individuals spend around 90% of their time indoors which threatens their health and wellbeing due to poor indoor air quality (IAQ). Therefore, this paper recognizes the impacts of indoor living walls on air quality and energy consumption in various countries. The results of previous studies include pre and post results of analysis and simulation that proves the reduction of concentration, total volatile organic compounds (TVOC), PM10, temperature, and an increase in relative humidity that reduces energy consumption, and boosted air quality using indoor living walls.
