On an office building, one of the largest green walls of Belgium was created (50.000 plants) that improves air quality, reduces heat stress, and improves biodiversity. The green wall also isolates the building, resulting in less energy use (Ref. 1-3). The wall consists of a variety of native plants and is irrigated with water collected on the roof of the building (Ref. 1, 2).
Overview

- Water management (SDG 6)
- Stormwater and rainfall management and storage
- Green space, habitats and biodiversity (SDG 15)
- Green space creation and/or management
- Environmental quality
- Air quality improvement
- Noise reduction
Focus
Creation of new green areas
Project objectives
The main goal of the intervention was to reduce air pollution including particulate matter and carbon dioxide that meets the sustainability strategy of the designers of the green wall (Ref. 1).
Implementation activities
Creating a living wall consisting of 50.000 native plants (Ref. 1, 2, 3). Creating a sustainable irrigation system which captures storm water from the roof in an underground water basin which stores 20.000 liters of water, which is used for the irrigation of plants (Ref. 4, 5). "The walls were given a two-layer makeover: first insulation, then plants. The plants grow in panels filled with rock wool. The rock wool is wrapped in felt. The felt retains the plants and moisture. There is a rainwater tank of 20,000 liters underground. This is enough to always have water in stock for the entire wall garden. An irrigation pipe runs through the entire wall, which waters the plants. And that is necessary because the plants receive three liters of water per day per square meter. Since no soil is used in this system, the plants need to be watered constantly and get their nourishment from the fertilizer that flows through the irrigation system with the water" (Ref. 5).
Climate-focused activities

Details on the roles of the organisations involved in the project
The project was commissioned by Intervest Offices & Warehouses (real estate company). The green wall was created on one of their buildings, which is now called 'The GreenHouse'. The renovation of the building including the green wall is designed by Conix RDBM Architects and the green wall is implemented by Ambius Belux (plant company) and Sempergreen (company specialized in green roofs and walls) (Ref. 1, 2).
