It is the most extensive green roof in Lublin, designed to cover 16,700 square meters rooftop area of the shopping mall 'Castle Terraces' (Tarasy Zamkowe). Its purpose is to serve as a green recreational area for relaxation and public events, as well as an ecological solution for heat mitigation and water retention. The roof is divided into two parts: 1) an area accessible to the public with flower meadows, walking paths, viewing points from which the visitors can see Lublin’s old town 2) ‘intensive cultivation area’ with endemic trees, bushes and succulents which are not directly accessible to the public [1,2,3,8].

Since the mid-eighties, several German cities like Karlsruhe have been implementing green tram tracks, followed by a period of decline due to incompatibility with technical and construction requirements (Ref. 2). Since around 2003, the city of Karlsruhe has re-introduced the greening of tram tracks with the main objectives of noise reduction and cloudburst infiltration (climate adaptation). Mostly in combination with urban redevelopment projects, several tram tracks across Karlsruhe have been renewed and greened in different forms by using continuously advancing technologies (Ref. 3, 6 and 7).

The project aimed to test the potential to use existing surface water drainage charge mechanisms to incentivize increased implementation of Sustainable Urban Drainage Schemes (SuDS) to improve flood resilience and improve water quality in the city of Manchester (ref 1). Working with partners from The Water Taskforce, and funded by the DEFRA (Department for Environment, Food & Rural Affairs, UK Env agency), BITC (Business in the Community) and CLASP, these partners have been testing the concept that implementing SuDS on a school site could generate savings for a school, by reducing their hard-standing area and so their charges from their water supplier. Working with two schools in Manchester, the project team carried out detailed audits and SuDS interventions were identified that could divert or slow the flow of water into the sewer system, or reduce the amount of chargeable hard-standing area. Using this information, a trial version of a simple, user-friendly tool has been developed to help schools identify if there may be a cost-effective way to drop a chargeable surface water band (ref. 2).

Number One First Street is at the corner of Medlock Street and Whitworth Street behind the train arches near Oxford Road Station in the city center of Manchester (ref. 6). During the redevelopment of the former BT building now called Number One First Street a green roof was installed (ref 2). Whilst the vegetation slowly established, it provided a habitat for invertebrates and insects. A green wall, accommodating 37,000 plants was planned to be installed by 2020 which would replace glass, plastic and metal cladding with greenery (ref 1).

Three London Plane trees were planted in a specially designed trench in Howard Street, Salford, Greater Manchester in 2015 with the aim of capturing the impact that trees had on both cleaning polluted water from road runoff and managing levels of surface water, which can lead to flooding when not properly managed (ref 1). This project in the City of Salford was created to study how trees can aid in the management of urban stormwater as a novel retrofitted street tree demonstration (ref 3). It was led by Manchester's City of Trees movement. (Ref 3)

The roof installation at the Re:center building comprises of a wildlife pond planted with native marginal plants, a native wildflower area, grasses and herbs, bird feeder tables, insect houses etc. Design features encourage the development of flora and fauna on the roofing area and a growing media (from ABG) provides a nutritionally rich base for vegetation. Beneath this surface, a free-draining void allows for storage of collected rainwater to irrigate the vegetation. This roof is part of the Bright Building at the University of Bradford. (ref2) The building was known throughout its building phase as The Sustainable Enterprise Centre, but it is recognised that thinking around sustainability has moved considerably since this project started back in 2007 and the new name will ‘re:flect’ new agendas in a way that is distinctive within Higher Education (ref 6).

In 2010 a new drainage system was installed in Traktoros Street that solved the disposal of surface-water so that bigger storms would not cause damages in the area and separates rainwater from the sewage. The rainwater is directed to the lake in Adyváros. The project was the third phase of the complex reconstruction of draining in the Szabadhegy neighbourhood. While the first two phases (the construction of the main pipelines and drainage of Pannónia Street; drainage of Vak Bottyán Street and paving streets) were financed by the municipality, the third phase was implemented with the help of the EU. (Reference 1, 2)

As part of the restoration of park Denis Gardens, an innovative water element was built consisting of water flowing down the stairs, circulated and cleaned by a pump and filters. This helps regulate the local microclimate by reducing temperatures in hot days and creating humidity in the air (Ref. 1; Ref. 5). Also, the element allows people to walk bare-footed and cool off. In addition, the water reduces air pollution by extracting dust from the air, and the structure has an aesthetic and recreational function, with a restaurant underneath. (Ref. 1; Ref. 2; Ref. 6).

"This 26-hectare park, the largest in Clermont-Ferrand, offers a privileged view of the city. Several wooded areas serve as shelters for permanent and passing wildlife. For the last two years, gardeners in the park have no longer used pesticides to maintain Montjuzet Park, the effects are already measurable on the enrichment of flora and fauna." "During the development of the Parc Montjuzet, the choice was made to keep 9 hectares without intervention. These hectares could be a source of some ecological richness. Hives have been established near this area since 2009." (Ref. 1) This park has the Refuge LPO label. (Ref 2)

Park Lužánky underwent extensive reconstruction between 1991-2012 through five phases (Ref 2) to restore a recreational hub of the city's largest park through ecologically sound design (Ref. 1; Ref. 2). Each phase worked restored different sections of the park. This included modification of green areas, landscaping (treatment of trees, planting new trees and perennial plants, restoration of grasslands), building a children's playground, a fitness park, and an artificial water element that imitates the former stream of the river Ponávka. (Ref. 1).
