Tetőterasz, Nádor 15
Short description of the intervention
The rooftop garden of Nádor 15 was implemented as part of the sustainable campus development strategy of the Central European University. It contains a community garden that is managed by the CEU community, intensive green roofs and green walls as well. The rooftop garden also collects water for it's automatic irrigation system and supports biodiversity with bat shelters, bee hotels and birdhouses. (Reference 1)

Goals of the intervention
The transformation of the rooftops of the Nador 13 and15 buildings of CEU into a communal roof garden space aimed at providing social benefits as well as functional environmental benefits. The goals of the intervention were providing a large addition of outdoor space to the campus, creating an island of urban biodiversity and serving as a medium for collecting rainwater, which will be used to irrigate the plants and will reduce dependence on using potable water for irrigation purposes. Further goals are to decrease the heat island effect in summer and to provide a place for a community garden for educational purposes (Reference 2)
Quantitative targets
The original targets were:
- rooftop cafe and garden with nearly 2,000 plantings of native species (Reference 3)
- to get BREEAM certification of sustainable development that standards are ordered along 10 categories; the features of the rooftop garden fits in the criteria of health and well-being (targeting comfortable and healthy environment of the occupants of the building), land-use (targeting habitat protection and creation, and long term biodiversity of the building site), management (sustainable aftercare and educational purpose), and water (sustainable use of water) (Reference 4, 5, 6)
Monitoring indicators defined
No indication that monitoring is performed (this was also confirmed in the email correspondence, see uploaded doc in the reference section).

Implementation activities
"Extensive garden areas comprised of planting boxes, tree planters, green walls and climbing plants have been added to the space [...]. Plant species were selected from a list of locally specific species found within the Carpathian Basin region, with specific selection of bird and bee friendly species which can ensure the relatively harsh environment of a rooftop garden. The entire rooftop surface area will serve as a medium for collecting rainwater, which will be used to irrigate the plant life, reducing dependence on using potable water for irrigation purposes. A special area of the garden has been designated as the CEU community Edible Garden, and will be utilized by community members to produce a micro version of an organic crop rotation, which will be maintained throughout throughout the seasons" (Reference 2).

Please specify novelty level of the innovation
The email correspondence revealed that "There are multiple design interventions which are quite unique within the region (green walls, permeable surfaces for collecting rainwater which feeds the irrigation system, automatic irrigation in the extensive garden areas) In addition to this the community roof garden area is the first of its type at a campus in Hungary. The community garden space has been integrated into course offerings which are held in the winter/spring semester each year, where participants have the opportunity to learn the basics of urban organic roof gardening, and put classroom skills learned into practice on site within the urban context". Besides, the green wall was implemented as an experimental design of the CEU's landscape contractor(see uploaded doc in the reference section).

Impacts, benefits
Description of environmental benefits
CEU's new campus, which features the green roof has been granted "Very Good" certification by BREEAM standards, which is an indicator of the sustainability of buildings over several issues including water use, ecology, management process and pollution. The 3204 perennials, 17 trees, 241 shrubs which were planted have increased urban green space and have reduced the heat island effect. (Ref 1) Rainwater collection reduces the fresh water consumption of these plants. The project has created habitats for bees, bats and birds.
Economic impacts
Description of economic benefits
Unknown
Description of social and cultural benefits
The green roof project is unique in Hungary as it is one of the only outdoor green walls in the country. (Reference 9) It has educational value for university students, but also locals and school children. The roof garden space also provides opportunity for locals to get involved in planting and maintaining of vegetation. (Reference 10)
Type of reported impacts
Indicators
The project got Very Good certification of BREEAM (Reference 6). The project created a cool urban space to escape from heat. It also created homes for bats, bees and birds. It's water management system collects rainwater for irrigation and helps with stormwater protection. (Reference 1) It creates an opportunity for locals to get involved in the governance and maintenance of the sustainable community garden. (Reference 10)

Finally I had two interviews, one with Logan and one with Katalin Miko from the Campus Redevelopment Office. The majority of the information is in Logan's interview, but Kata provided more detail about the involvement of the ceu community in the evaluation. I could only upload one of them in the interview section, please find Kata's interview under additional attachments.
