Climbing façades

In 2008, Mahidol University in Thailand announced its revised five-year Green Campus master plan titled 'A Promised Place to Live and Learn with Nature' for its main Salaya Campus. The scheme aimed to promote a green conscience and lifestyle for its students and faculty through sustainable campus developments that consider social and environmental aspects. The university's objectives were to achieve energy conservation, environmental sustainability, and social cohesion and well-being. The main features of the master plan included the creation and maintenance of green open spaces covering at least 70% of the campus premises, optimization of land use, transformation of infrastructure to encourage cycling, creation of outdoor learning, recreational and research areas, and enhancement of local biodiversity. The master plan also covered guidelines and targets for energy consumption, waste, and water management in the campus buildings. The Siri Ruckhachati Nature Park, the university's arboretum, was also redesigned with green and blue areas playing a role in flood management. Following the 'Green Campus' master plan, Mahidol University developed its existing mission further and became an 'Eco University' in 2012 and a 'Sustainable University' in 2021. These two missions focus primarily on reducing energy consumption and waste management.

As an industrial development practice that involves a symbiotic connection between materials, energy, natural systems and local communities, the concept of green industry has become a point of focus for a factory in Rangapur, Karupannya Rangpur Ltd., designed by Architect Bayejid Mahbub Khondker and his team. The factory has become a pioneering example in the "green industry" initiatives in Bangladesh (2).
The factory has a green façade of climbing plants, as well as a green rooftop and integrated green elements, designed specifically to incorporate a once extinct industry, the Shataranji (weaving style). The intervention was designed to respond to human and enviornmental needs (2,7). From a human perspective, the intervention responds by improving work conditions for the workers by introducing green spaces that help with local temperatures and relaxation. From an environmental perspective, the project responds to challenges related to energy efficency (3,4).
The factory architecture incorporates cultural and indigenous knowledge with the utilization of natural light, wind, water, and flora while maximizing the use of natural elements and the idea of "Reuse and Recycle." The factory's roof features the Nandini Park, where employees can relax and eat lunch. The Nandini Park is surrounded by flowering plants and vegetation. (1, 2, 4, 6)

The Urban Farm Office building, is a concrete-framed structure covered in a "vertical farm" of vegetables, fruits and herbs. The building was constructed by the Vietnamese architectural firm Vo Trong Nghia (VTN) Architects in early 2022 as its own headquarters in Ho Chi Minh City. It aims to promote the production of safe food while reintroducing green space to the city with a façade covered in vegetation. Furthermore, the project also seeks to address the absence of green space that contributes to a number of socioeconomic issues, including air pollution, flooding, and the heat island effect. VTN Architects' idea for the Urban Farming Office includes the area of space-efficient food production in cities through vertical urban farming in addition to the core objective of restoring vegetation to urban structures.

Asia is one of the fastest economic growing regions and so are many cities on the Asian continent. Economic growth brings forward many challenges including intensive urban development, loss of natural features, increased urbanization, and high levels of air pollution, just to name a few. One of these cities is Ho Chi Minh where it was assessed that only 0,25% of its area is covered with vegetation, and in addition to this, there is traffic congestion and air pollution (3).
In an effort to rectify some of these transgressions, a private initiative developed a house called the House of Trees, located in Tan Binh district, one of the most densely populated residential areas in Ho Chi Minh City, where many small houses are crowded together (2).
The green features of the house include five roofs that function as gardens thanks to a layer of earth substratum, from which tall tropical trees grow (3). The aim of the project is to bring green space back into the city, accommodating high-density dwellings with big tropical trees. Five concrete boxes are designed as "pots" to plant trees on their tops. With a thick soil layer, these pots also function as storm-water basins for detention and retention, hence contributing to reducing the risk of flooding in the city. The project has been conducted by Vo Trong Nghia Architects, a leading Vietnamese firm in building green architecture in urban Vietnam. (1)

Penang is a state located in north-western Peninsular Malaysia with an area of 1,049 km2. It comprises two local authorities, Penang Island and the mainland. The former is further divided into five administrative districts which are further divided into mukims (sub-districts). Two urban mukims located on the island – George Town and Bayan Lepas – are the focus of the proposed nature-based solutions (NBS) climate adaptation programme. The programme was launched in 2022 by UN-Habitat in collaboration with the Ministry of Environment and Water (KASA) of Malaysia, Penang Island City Council (Majlis Bandaraya Pulau Pinang - MBPP), Department of Irrigation and Drainage (Jabatan Pengairan Dan Saliran - JPS) and Think City (a wholly-owned subsidiary of Khazanah Nasional Berhad (the sovereign wealth fund of the Government of Malaysia)). (Ref 1)

The implementation of the project responds to several challenges posed by climate change including heatwaves and flooding (Ref 4). The main goal of the programme is to enhance urban resilience and reduce human and ecosystem health vulnerability to climate change impacts and extreme weather events by implementing nature-based solutions (NBS) such as tree-lined streets, pocket parks, green parking spaces, green facades and rooftops, urban agriculture and blue-green corridors to reduce surface temperatures and stormwater runoff, as well as to increase social resilience and build institutional capacity (Ref 1, 3).

Food safety has come a long way and today it is one of the biggest challenges globally, especially in the developing world. According to the World Bank, Viet Nam is one of the countries prone to food-borne illnesses and food safety is a major concern for the public there (1). Increased droughts, floods and salinization have further enhanced and endangered food supplies. Access to healthy food is not optimal. To solve this issue, some Vietnamese private companies came up with a solution. In 2013, a shoe factory in the city of Dongnai (located around 30 km away from Ho Chi Minh City) established a welfare facility for the factory's employees, called Farming Kindergarten. The building was designed with the idea of serving 700 children of the workers by providing healthy food, as well as environmental education. The design includes a green roof where vegetables are cultivated alongside playgrounds for the children. The roof is designed in such a way that it is the perfect environment where children learn about the importance of agriculture and strengthen their connection with nature (2, 4, 6). The harvests from the garden are distributed to the children's families, contributing to a rather small family budget of Vietnamese workers (the average income of Vietnamese workers is just 180 USD per month) (7).

Al Shaheed Park is the largest park in the country. The park was designed to include besides its green spaces, several buildings (museums, parking) populated with green roofs and an artificial lake. The size of the park with all the mentioned grey and green elements stands at 20 ha. The park is viewed as an encompassing part of a green belt that surrounds the city of Kuwait. From an environmental point of view, the park was built to protect the city from sandstorms and to reduce air pollution. From a cultural point of view, the park and the museums are providing the public with high-quality programs, events and spaces, and part of their mission is to spread awareness and educate the public on the importance of the country’s land, history and environment, in addition to the encouragement of international and regional exchange of arts. In addition, the park is meant to commemorate the victims of the first Gulf War. (1,2,3)

This intervention was initiated in 2014 in Agege, a slum and a city in itself belonging to Lagos. Agege is one of the 7th most populated low-income communities in Lagos with a total population of around 1,033,064 people. Climate change in Nigeria led to seasonal droughts and floods, causing pressures in terms of food security as well as high temperature and humidity levels which affect directly the economically disadvantaged population in the slums of Lagos. In 2014 a research team at the University of Cardiff alongside community leaders of a Yoruba community in Agege implemented a study on vertical gardens in residential areas with the purpose of alleviating local temperatures and enhancing biodiversity. The implementation started with a study and was continued with the introduction of practical gardens maintained by the local community of 3 residential buildings (one in Suru Street, another in Lagos Street in Agege, and a third in Abeokuta Street).

Santalaia is a high-end, multi-family residential building located in the heart of downtown Bogota, Colombia. Santalaia is often referred to as "the green heart of Bogota" and is seen as an icon of sustainability [1]. The 11-story building was completed in 2015 and all eleven floors are engulfed in many species of plant wildlife to encourage biodiversity. There are 115,000 native plants of 10 different species covering a total area of 3117 m² [2,3].
The plants included on the exterior of the building rely on a hydroponic system and provide a model of how to increase green zones in urban areas. A vertical garden of this size provides natural beauty in the middle of concrete Bogota while mitigating the carbon footprint of more than 700 people. An additional benefit of Santalaia’s vertical garden is that the plants create a “green carpet” that serve as insulation and reduce the use of air conditioners, an increasingly valuable contribution during times of rising temperatures due to climate change [5,6].

This project started as a grassroots movement by Hunter’s Bar Infant School (HBIS) in Sheffield when they were seeking to actively help to protect children from air pollution. HBIS led a fundraising campaign that, in collaboration with the University of Sheffield, provided the base to create a green barrier in their playground. The NBS is part of a bigger study called BREATHE that provides the science behind the project, which involves the design of the green barrier, the assessment of its impacts and a feasibility evaluation for installing green barriers in other schools in Sheffield and in Buenos Aires.
