Implement solutions to help reducing energy consumption or support the use of sustainable energy resources

IKEA opened its doors in Budapest in 1990. This was the very first store in Hungary. Twelve years later, the store announced that it would install a green roof. The main purpose of the green roof was to compensate the locals for the loss of green space. The green roof was intended to create a biologically active surface that fits in aesthetically into the suburban landscape and provide a home for animals such as pollinators. The green roof, built in 2002, was covered with a Sedum carpet. In 2014, when the original Sedum vegetation died out, the green roof was completely removed. Then, during the autumn 2014 planting, four types of Sedum shoots were seeded. This was followed in the spring of 2015 by the seeding of herbaceous dicots seed mixes, which contained seeds of roughly 50 plant species. The vegetation is regularly monitored by ecologists: in 2021, more than 160 different taxa were recorded, including spontaneously occurring species. The green roof is closed, not accessible to the public, however tours are occasionally organized for professionals [3] [6] [8] [9] [10] [11].

The green roof development forms a 400-meter-long floating green ribbon above the SM North EDSA mall in Quezon City, Philippines. [3] It boasts a 15000m2 area filled with 55 species of native trees, bushes, and flowers that thrive in the local climate, and it relies on stored rainwater runoff to sustain its plant life. Visitors can access the mall via entrances located within the garden's openings and tunnels leading to shops and cafes nestled beneath the botanical landscape. A meandering pathway guides visitors through the space, which features various entertainment options. The garden provides a unique and innovative space for mall-goers and city dwellers to relax and interact with nature. [1,2]

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 roof garden is one of the most distinguishing features of JEG Tower @ One Acacia, a 22-storey commercial tower in Cebu City. [1] Featuring the purely endemic flora of Cebu, the roof garden offers a dedicated green space in the middle of the cityscape to tenants and visitors of the buildings. The project was created to contribute to the preservation of Cebu's Biodiversity, combat air pollution and improve the mental and physical well-being of residents and visitors. [1] It also includes an events space that people or companies could hire [4].

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).

The International Cultural Garden Park (IC Park) is a comprehensive, private-sector-led, green development project in Yarmag, Ulaanbaatar, Mongolia. Initiated in 2021 by the Ikh Uilsiin Ereld Group LLC on its own property land as part of its social responsibility, the planned area covers a 35 hectares (86 acres) site. First, an international design competition was announced to plan the project. As a result of this competition, a contemporary park concept was developed for Ulaanbaatar's New Center to convey an international concept, with designs of significant cultural and historical elements from over ten different nations. The IC Park will also serve as a venue for a variety of international events, including conferences, sporting competitions, cultural festivals, and more. Green technology is being used with particular attention throughout the park's construction, and more than 90 species of trees and about 50 species of natural perennials growing in Mongolia are planned to be planted with the cooperation of professional tree planting and gardening organizations, specialists, researchers, and scientists. As of today, more than 7,000 trees have been planted in the project area, and professional personnel are diligently working on their care and pruning. The project is expected to reduce the negative consequences of global warming, create a greener environment, and secure long-term employment. (Ref. 1, 2, 4, 7)

A green wall of 73 square metres was constructed on the building of the Federación de Entidades Empresariales Privadas de Cochabamba (FEPC, the Federation of Private Business Entities of Cochabamba) (Ref. 1). The vertical ecosystem comprises over 3000 plants of 35 species and is considered the first vertical garden to have been created in Bolivia (Ref. 1). The green wall is considered to have 'beautified' the city of Cochabamba, but is also considered to "contribute... effectively to the preservation of the environment" (Ref. 2).

The Sustainable Residential Complex project was a measure taken by the city of Dubai, one of the largest city ecological footprints, with a goal to reduce it to the smallest ecological footprint by 2050. For the past two decades, the UAE government has made an effort to lower its own dependency on fossil fuels, shifting toward more environmentally-friendly sources to power its cities. The sustainable residential complex development project is one of the few initiatives taken by the city administration of Dubai under Vision 2021. Located just outside Dubai the area is the first operational net-zero energy residential complex in Dubai. [1, 2]

The Gangxia 1980 green roof, a pilot of the Green Cloud project, was launched by The Nature Conservancy (TNC) in collaboration with key partners, including: Zhubo-AAO; Glocal Estate Management; and Urban Planning & Design Institute of Shenzhen (UPDIS) [1]. Located on an old building in Gangxia village in Shenzhen, the project utilizes three-dimensional light steel structures that are simple to construct and have the capacity to hold over 420 plant containers, filled with plants mostly native to Southern China [1, 2]. The original concrete rooftop is transformed by vegetation, which is capable of absorbing and preserving rainwater, creating a nature-based stormwater management system for the residential building, achieving a 65% of run-off control rate [1, 2]. As a result, a living “green cloud” is formed on a rooftop of Gangxia village, showcasing “a model to improve the urban village’s stormwater management system and its living environment” [1. p.33].
