Living walls can be decorative, produce food or be made of medicinal plants in small areas. Living walls provide energy savings through reduced heat absorption and can improve the quality of indoor air.
There are many benefits to living walls, which include:
- lowering energy consumption and greenhouse gas emissions
- reduction of Urban Heat Island Effect (UHIE)
- increasing the thermal performance of buildings
- improving indoor air quality (IAQ)
- reduction of noise pollution
- increasing urban biodiversity (the variety of different types of plant and animal life in a particular region) and urban food production
- improvement of health and well-being.
Building a living wall indoors can be used on any scale to improve the inside air quality by the plants absorbing carbon dioxide and emitting oxygen. Plants provide a calming effect as well as increase worker efficiency.
Outside living walls can absorb the sun's energy into the growing plants rather than into the building structure, lowering overall heating and cooling costs. Living walls also absorb sound waves, reducing city noise.
