Green Plant Walls as Indoor Air Quality Enhancer in the Recently Built Office Building

Nowadays one of the main focus of public and occupation health is maintaining good indoor air quality in office building and public spaces. The aim of this study was to identify indoor air quality, its influencing factors, sources of pollution and air quality enhancers. The results indicate that indoor air quality does not exceed the permissible levels for office buildings based on found chemical pollutants and CO2 readings. Identified sources of chemical pollutants were printers with tonner, personal cosmetic products of workers, hand disinfectant and office cleaning products. Measurements indicated well-ventilated rooms. However, the control floor showed lower air humidity levels. Results shows up to 21% air humidity boost from plant green walls on weekends and up to 9% boost on workdays. The green walls with living plants help maintain good humidity levels.
