1. General information
2. Objectives of the intervention
Goals of the intervention
The main goals of the green roof and green courtyard / patio were improvement of air quality (by filtering particulates), creating aesthetic value for students, citizens and employees of the surrounding buildings and patients of the hospital, attraction of insects (habitat), storm water retention and reducing temperature (Ref. 1, 2).
Quantitative targets
The building has a total area of 13,000 m² (Ref. 1).
Monitoring indicators defined
Total area of building (Ref. 1).
Humidity of plants is monitored (Ref. 2).
Humidity of plants is monitored (Ref. 2).
Sustainability challenge(s) addressed
Climate change adaptation: What were the goals of the NBS?
Climate change adaptation: What activities are implemented to realize the conservation goals and targets?
Habitats and biodiversity conservation: What types of conservation goals are / were defined for the NBS intervention?
Habitats and biodiversity conservation: What activities are implemented to realize the conservation goals and targets?
Implementation activities
Building the campus building that hosts 1500 students (Ref. 1). Creating a green roof with diverse vegetation that attracts insects with an extra thick substrate layer, that creates a nice view from the surrounding buildings (Ref. 1). Creating a patio / courtyard with Cornus trees and vegetation with a manageable irrigation system at the heart of the campus building (Ref. 2). "The roof garden is also favorable for urban nature: the green roof offers space for a variety of partially indigenous plant species and therefore also spontaneous insect species. Finally, the green roof filters fine dust from the air and absorbs sound; two major city themes today" (Ref. 1). "The patio of Campus Noord is more than an inner garden. It is the central space around which circulation, meeting and communal functions are grouped" (Ref. 3).

Type of innovation
Please specify technological innovation
The irrigation system can be considered innovative: a separate substrate top layer for the plants is created and a 60 m3 lower substrate layer for the Cornus trees. Because of this extra thick substrate layer, more storm water can be stored and higher plants can grow which enhances benefits (temperature reduction and air quality improvement). The plants are irrigated with drip irrigation which is adjustable per location (there are multiple 'vegetation island' in the patio) as this varies because some vegetation islands are in the sun while others are in the shadow. The irrigation system includes a humidity sensor that stops the irrigation when a certain treshold is reached (Ref. 2).
Novelty level of the innovation
Please specify novelty level of the innovation
The construction of the campus building with a green roof and green patio/courtyard is the first in Antwerp (Ref. 1).
