Please specify "other" stage of the intervention
The project is part of the Sveavägen 44 project, which started the year 2011. (Ref 3)
The roof park was completed in the year 2015. (Ref 1)
Goals of the intervention
The goals were to create a roof park with great ecological biodiversity (including both plants and insects). The goal was also to create a park with a natural biotope that would take care of itself (with little need for maintenance). Furthermore, the park is to be used for recreational purposes, with space for walks and meetings. (Ref. 2, 5)
"Additionally, Roofscape Sveavägen aims to convert the office space into a modern meeting place integrated with the environment. It serves also as a place for recreational activities with spaces for walks. The rooftop spread the message of health and well-being, social justice, cohesion and equity. " (Ref. 9)
Quantitative targets
The international environmental certification system BREEAM (applied to the property with the roof park) includes reduced energy consumption by more than 70%, which means reduced CO2 emissions of approximately 1000 tonnes/year. (Ref. 7)
During summer evenings around 300 visitors per evening are expected. (Ref. 1)
Monitoring indicators defined
Energy consumption, number of visitors, number of trees. (Ref. 1, 9)
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
Over 70 different species are included from three suitable natural habitats that were chosen for the roof landscape, including e.g. shrubland (sv. Krattskog). (Ref. 6, 1)
"The plants come from typically wind-swept, dry and exposed locations in the landscape; steep slopes in the mountains; the Outer Archipelago or barren dry meadows on Gotland. The only care over the year is a mowing in the late summer after the seed spread. No watering except the natural rain...Roofscape Sveavägen is a place of diversification (including both plant communities and insects) in order to create a natural biotope that would take care of itself." (Ref. 9)

A walking trail has been created as well as places for people to sit (for recreational purposes), the transparent wood structures (sv. träribbverk) which have been placed are used for the purpose of creating space, protecting from wind and also protecting certain parts of the nature in the park and the small birds and bumblebees that live there. (Ref 1)
