Native title of the NBS intervention
Groen dak en binnentuin op Campus Spoor Noord
Short description of the intervention
The green roof and courtyard/patio on a new campus building of the University of Applied Sciences consist of trees and plants that reduce temperature and improve air quality. The plants are grown on a thick substrate layer that allows for extra stormwater storage. The vegetation also provides habitat for species such as insects, filters particulates from the air and reduces noise, and creates aesthetic value for patients in a nearby hospital (Ref. 1).

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

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).

Please specify the roles of the specific government and non-government actor groups involved in the initiative
The campus building is initiated by the Artesis Plantijn Hogeschool Antwerpen (University of Applied Sciences) and financed by the Province of Antwerp (regional government) (Ref. 1, 4, 5). The building was designed by Stramien architects and built by Van Laere (building company) ( Ref. 1,4). The plants, the substrate layer and the irrigation system were provided by H4A (landscape development company) and the trees by Van den Berk (tree company) (Ref. 2).

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).
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).
Replicability/Transferability
Impacts, benefits
Description of environmental benefits
Climate change:
Lowered local temperature:: the vegetation reduces heat (Ref. 2).

Environmental quality:
-Improved air quality/Reduced noise exposure: the vegetation improves air quality, reduces local temperature (which is enhanced in the patio/courtyard where the patio helps circulating air in the building) and reduces noise (Ref. 1).

Water management and blue areas:
-Improved stormwater management: the vegetation captures storm water and the substrate layer stores storm water (Ref. 2).

Green space and habitat
-Increased green space area:
-Increased number of species present: the diverse vegetation attracts insects (Ref. 1).
Economic impacts
Description of social and cultural benefits
Social justice and cohesion:
-Improved access to urban green space/Increased opportunities for social interaction: "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).

Health and well-being:
-Gain in activities for recreation and exercise: the patio/courtyard provides space where students can relax and it creates aesthetic value for patients of the hospital (ZNA Cardix) which will benefit their wellbeing (Ref. 1).
