Living walls (also called biowalls, “mur” vegetal, or vertical gardens) are composed of pre-vegetated panels or integrated fabric systems that are affixed to a structural wall or frame. Modular panels can be comprised of polypropylene plastic containers, geotextiles, irrigation, and growing medium and vegetation. This system supports a great diversity of plant species, including a mixture of groundcovers, ferns, low shrubs, perennial flowers, and edible plants. Living walls perform well in full sun, shade, and interior applications, and can be used in both tropical and temperate locations.
Due to the diversity and density of plant life, living walls require more intensive maintenance (regular water, nutrients, fertilizer) than green façades.
Sustainable Sites Credit 7.1: Landscape Design That Reduces Urban Heat Islands, Non-Roof (1 point).
Exterior green walls reduce the solar reflectance of a structure, thus reducing the urban heat island effect.
Water Efficiency Credits 1.1, 1.2: Water Efficient Landscaping (1 to 2 points).
Buildings can incorporate a stormwater collection system for irrigation of the green walls and other landscape features. Using only captured, recycled, or nonpotable water may enable the project to achieve this credit.
Energy and Atmosphere Credit 1: Optimize Energy Performance (1 to 10 points)
Green walls can provide additional insulation and natural cooling, which reduces a building’s reliance on mechanical systems.
Innovation in Design Credits 1-4: Innovation in Design (1 to 4 points)
Green walls may contribute to innovative wastewater or ventilation systems.
