1. General information
2. Objectives of the intervention
Goals of the intervention
1) Giving back to the locals as much of the park occupied by the department store as possible; 2) Creating more urban green spaces; 3) Increasing the biodiversity; 4) Paying attention to the climate change and empowering adaptation to the climate change risks - e.g. the green roof reduces the stormwater runoff and cools the roof surface thereby reducing the urban heat island effect. [1] [3]
Quantitative targets
Quantitative targets:
1) Covering with plants the roof surface at 6500 square metres; 2) Sowing at least 50-60 plant species.
Qualitative targets:
1) Reducing air pollution (dust, toxic gases) 2) Saving energy (by heating and cooling the building) 3) Protecting the roof material from UV radiation and extending the lifetime of the roof

Monitoring indicators defined
- The presence of different plant species is regularly monitored
- Insect species and other animals living on the green roof are also monitored regularly [1] [3] [11]

Implementation activities
1) Removal of the previous Sedum green roof; 2) Installation of the different layers: drainage membrane, root barrier, filter fabric, growing medium; 3) seeding the special seed mix of 50 species [6]
3. NBS domains, ES and scale
4. Governance and financing
5. Innovation
Type of innovation
Please specify technological innovation
The green roof protects the roof structure, especially the top layer, from UV rays, giving it a longer lifespan. A green roof is a technological innovation that keeps the heat inside in winter and cools the building in summer. It reduces the noise infiltration and binds dust. Extensive green roofs are self-sustaining, requiring no irrigation, horticultural intervention or fertilizer [1] [5].
Novelty level of the innovation
Please specify novelty level of the innovation
The Sedum green roof was installed in 2002. In 2014, when the original Sedum vegetation died out, it was completely removed and replaced with perennials - grasses, herbs, drought-resilient plants. Now it is an extensive, biodiverse green roof [6].
