실내환경 개선을 위한 ‘Bio Green Wall System’의 효과

Effect of the Bio Green Wall System for the Improvement of Indoor Environment

Green wall technology is increasingly popular to improve comfort and air quality inside the building. However, existing green walls only involve mostly irrigation system and are costly. They need the improvement in multiple aspects for long-term maintenance. In this study, we aimed to develop a functional module for plant growth, spatiotemporal convenience, and space utilization in order to develop effective green wall technology. The module was manufactured and attached to a ‘Bio Green Wall System’ with air purification system. This ‘Bio Green Wall System’ gives the effect of air purification by the plant as well as air purification by the carbon filter. The ventilation system provides oxygen to the root facing towards the back of the pot to allow the plant to grow healthy. The developed functional module supports growth of a variety of plants. The module can be installed in various indoor and outdoor locations, and allows quick and convenient replacement and plant maintenance. Concentration of TVOCs and fine particles in the office decreased significantly with green wall compared to the control, and TVOCs was significantly lower with the ‘Bio Green Wall System’ than with the conventional green wall system. HCHO was significantly reduced with the green walls, but there was no significant difference in CO₂.
