Improved stormwater management

Marks & Spencer transformed its Newcastle city centre store on Northumberland Street into one of the most eco-friendly in the north-east. (1) The striking development to the store includes various eco-features including the installation of a green living wall to improve the insulation of the building encourage biodiversity and improve customer experience (2, 3). The project also fits into Newcastle City Council's intention to transform Northumberland Street, and its surrounding area, into a European-leading retail destination (9)

Bryggen, the old wharf of Bergen, is a reminder of the town’s importance as part of the Hanseatic League’s trading empire from the 14th to the mid-16th century and is on UNESCO's list of the world's cultural heritage. For about 30 years, large amounts of groundwater leaked, threatening the survival of the ancient site. In order to address this, sustainable water treatment and climate adaptation measures (involving the largest rain garden of Norway, swales etc.) at Bryggen were used to restore the water balance at Bryggen. (Ref. 1)

"Nancy Grand Coeur" is the name of an urban renewal planning project in Nancy, which included several blue and green interventions. This area of Nancy received in 2009 the "EcoQuartier" (Eco-District) French label even though the renewal planning works started later, and are still ongoing. "Completely remodeling this district to make it an engaging "facade", adapted to the lifestyles of the time and to the evolutions of modern town planning (diversity of activities, fluidity of travel, sustainable development ...): that is all aims of the Nancy Grand Coeur operation" (Ref. 3).

Carillion-igloo, a joint venture company formed between The igloo Regeneration Partnership and Carillion plc was selected by Newcastle City Council and the Homes and Communities Agency to work in partnership with them in the redevelopment of a number of sites in the Lower Ouseburn Valley, Newcastle.
The regeneration project has been carried out in line with the sustainable investment policy of Igloo and consists of 5 phases. Phase 1: The Mailings focused on the transformation of a former industrial brownfield into a vibrant residential area on the banks of the Ouseburn promoting sustainable, low-energy living, flood protection and community building. These objectives were achieved by green areas creation, sustainable drainage system application and unique urban planning measures. (2, 15)

46.5 hectares of nationally-important habitat was restored in Doncaster as part of an Environment Agency-led project benefiting communities and wildlife. The work across seven woodland areas was designed to help improve water quality, reduce flood risk, and enhance natural habitats for protected species. By providing additional flood storage the project is able to help attenuate both peak and flood flow from rainfall events, reducing flood risk and damage and reducing the financial and carbon cost of pumping water from the Torne catchment. Although this project extended beyond Doncaster, Sandall Beat in Doncaster was part of the key sites (Ref 1).

The Desjoyaux ZAC in the Crêt-de-Roc district, was created in 2005. Since then, this three-and-a-half-hectare site, which is involved in the process of receiving the "eco-district" national label certification since 2015, has metamorphosed (Ref. 1). Some works aim to renew and embellish the public spaces located near the residences of the street and the impasse Desjoyaux to preserve biodiversity in the city center of Saint Etienne and for the well-being of citizens. (Ref. 1, 2 and 3). Community gardens, park, ephemeral gardens, swales and sustainable water filtration system are being developed in this project (Ref. 1, 2 and 3).

The Brunton Park residential area in the northern part of Newcastle had a history of flooding as a result of urban growth in the local area and developments in the upper parts of the Ouseburn catchment. A total of 62 properties were at risk of sewer flooding whilst 74 properties were located within a flood zone. In 2014, the collaboration of the Northumbria Water, the Environmental Agency and the Newcastle City Council created the Brunton Park Flood Alleviation Scheme with the strategic objective to reduce the potential for flooding of adjacent properties from surface water and the Ouseburn, whilst also developing a sustainable, self-maintaining channel which supports environmental, social and economic purposes at the same time. (12)

The project included physical measures of embankment building, diverting part of the Ouseburn river, installation of sewage storing tank, and creating new water-dependent habitat (12)

This vertical garden was created with the aim to integrate the shopping mall in the surrounding green. A total of 44.000 plants of 200 different species were used on a surface of 1.262 square meters, making it the largest living wall in the world (now in Italy) at the time it was created. The green wall has met large positive response both by the owners of the shopping mall, who noticed a decrease in their energy expenses, and by local residents, who can appreciate the aesthetic beauty of the wall and breathe fresher and cleaner air.

A modern office building in Poznan and a headquarter of a large company was designed to include multiple environmentally friendly solutions like cycling facilities, energy-efficient appliances in the building, roof gardens, the use of rainwater in the sanitary facilities, waste segregation system and the overall energy-efficient design of the building façade to let in as much natural light as possible [1].

The project, concerning the installation of an experimental site for research and demonstration on the environmental benefits of the green roof in urban areas, arises from the need of the public administrations, and in particular the City of Genoa, to get a thorough technical knowledge in order to make urban planning tools more effective in the process of improving life quality in the urban environment (1).
