Lowered local temperature

The Royal Gardens, situated between Piazza San Marco and the Bacino di San Marco, came into being during the Napoleonic occupation of the city and used to be a space for recreational activities for locals for many years after the monarchy was over. During past decades, the gardens have progressively deteriorated. Their original design is now barely legible, in terms both of geometrical patterns and the placement of trees and shrubs. They were rapidly becoming a derelict area. This intervention consists of their recovery by restoring the original vegetation by recovering still-living plants and introducing new ones. Between 2015 and 2019 the Gardens underwent complex restoration, carried out by the Foundation and planned by the gardener and landscape architect Paolo Pejrone, student of Russell Page and Roberto Burle-Marx, while architectural renovation and the rebuilding of the greenhouse was planned by architect Alberto Torsello, based on a project drawn up by Carlo Aymonino and Gabriella Barbini. Reopened in December 2019, the Royal Gardens, rich in unexpected perspectives and luxuriant growth, have reacquired their formal excellence and botanical complexity, in coherence with their historic nineteenth-century design.

As part of the Fifth Dimension research program of the University of Helsinki that examines green roofs from the perspectives of biodiversity and the three dimensions of sustainable development (ecological, social and economical sustainability), 8 green roofs were installed in Helsinki. The aim was to find economically viable solutions that are applicable to Helsinki’s and Finland’s conditions. The project experimented with green roofs in different parts of the country, over half of which are in Helsinki (ref. 1, 2, 3).

To test the newly developed Green Factor Tool for the City of Helsinki, with a focus on water management, two test sites (ätkäsaari pilot block and the three model yards in Kuninkaantammi) were created at residential blocks in Jätkäsaari and Kuninkaantammi. The tool itself is an Excel interface that calculates the quantity and quality of the city's green spaces per unit of area, It is part of the larger iWATER (integrated stormwater management) project (Ref 2). Specifically, after testing it on these two pilot sites, it is to support land use planning processes by providing a way to account for the quantity and quality of green space. The project aimed to analyze the cost-benefit of implemented sustainable stormwater solutions, compile stormwater-related planning tools as well as increase and strengthen the capacity of cities to work with stormwater issues (ref. 2).
One of the key objectives of developing the green factor method was to create green urban environments that have social value. Also, functionality was the second most important and cityscape (or landscape value) was the third most important category in green factor scoring.

The biggest park to date for the new town of Cherrywood in South Dublin is being developed. Tully Park will be part of a major strategic development in the area which will contribute to the economic growth of the county through the development of a vibrant residential and economic community anchored around a town centre. The park will act as a recreational space, and the plan is to create a high profile, high quality and distinctive flagship park with a range of visitor attractions and diverse active and passive recreational facilities. Schedule of provision to be informed by the current Dún Laoghaire Rathdown Open Space Strategy and local needs at the planning application stage but may include e.g. flagship playground, local pitches, courts, tea-rooms, toilets, public art, litter bins, street furniture, interpretation. The development of Tully Park shall be appropriate to the tranquil character and setting of the cluster of national monuments at its centre. The mature trees in the vicinity of the Tully Church complex shall be retained in so far as possible. (ref 1, 3, 5)

This project deals with the creation of a green roof and a green area around the new headquarters of the IDOM Group (an independent multinational company that offers professional integrated services in Consulting, Engineering and Architecture around the world), located in an old French warehouse (a customs warehouse) on the Deusto canal in the port of Bilbao. It has an area of ​​14,400 m2 dedicated to offices, research and development spaces such as white room and workshop prototypes, and social spaces. (Ref 1)

The experimental green facade system consisting of four different types of green wall was installed in Nurnberg from 2013 until 2016 on Adolf-Braun-Strasse 33 and is an integrated greening system that enables self-sufficient, low-maintenance "hanging gardens" on facades and other vertical walls. The aim of the project is to experiment with recreating green spaces in the streets, asphalt surfaces, and backyards of some parts of Nuremberg overcoming numerous constraints and competing uses (1) The implementation has helped improve air quality, thermal insulation, wind and rain protection and lowering local temperatures in its proximity.

The Veneto Eye Bank Foundation, a social welfare organization and regional centre of reference for cornea transplantation and research into epithelial stem cells, is a distinct and iconic project which embraces architect Emilio Ambasz's philosophy of "The Green Over the Gray," or the landscape over the building. It is a triangular-shaped building with a series of landscaped terraces at each floor level on one side. On the opposite side, the building rises as a series of steps that lead to a flat planted roof garden turning it into an outdoor amphitheatre. The combination of the plantings and deep overhangs minimises the impact of heat loads by blocking sunlight during the middle of the day (ref 1).

The Podlasie Opera and Philharmonic – European Art Centre in Białystok ("green opera") in Białystok, is known for its green roofs, green walls and extensive gardens, which perfectly harmonize with the surroundings. The green area serves as a platform for cultural events and successfully promotes the city. Opera gardens are divided into several levels with lawns, walking paths, bridges, sculptures, and small ponds. Different green elements of the building reduce heat effect and noise, increase the thermal insulation of the building, improve local biodiversity and limit rain drainage to the city centre [1].

The company running the Zabalgarbi waste disposal site manages a solid waste–to-energy plant and also houses a mechanical biological treatment (MBT) plant, a composting plant, a landfill and a leachate treatment plant. During construction of the first plant, Zabalgarbi regenerated and recovered the entire Artigas-Arraiz area covering 108 hectares. The area was degraded by shaft mining activity and an opencast quarry. The project aimed at the reforestation and landslide mitigation of this degraded area. Today the area has been reforested, trails were built and space provided for people to enjoy themselves in gardens, picnic areas and along forest tracks. (Ref 1)

On 'De Roma', an old cinema that has been renovated into a theatre, a green roof of 650m2 was created which improves biodiversity and contributes to Antwerp's climate change adaptation (Ref. 1, 4). A bee house was also later installed on the roof (Ref. 2). The green roof is created by volunteers of De Roma and Kopspel, which is an organization that provides learning-working places for student of 'Deeltijds beroepssecundair onderwijs (Part-time Secondary Professional Education) and temporary employment for people that want to turn back to the labour market (Ref. 1).
