Refrigerating Jar in Ghana

For the first time in the history of the LafargeHolcim Awards, the global jury selected three of the 40 Acknowledgement and Next Generation prize-winning projects from the regional phase of the competition in 2017 to receive LafargeHolcim Awards Ideas prizes. “We felt that they offer exciting and novel ideas, even within proposals that are not yet fully developed,” said jury head Alejandro Aravena.

The striking storage tower for the Nyingali community is designed to induce a chimney effect to keep shea nuts cool and fresh before processing. By storing the nuts and processing them incrementally, the community will be able to sell processed shea butter for skin moisturizing when it commands a higher price in the market cycle.

The base of the tower is a storage space with a double layer masonry construction designed to keep the interior cool. Its ceiling is made of glass foam, which is designed to act as a heat exchanger when damp. The volume above is cross-ventilated and draws hot air upwards. This project, which also includes a range of training programs, is part of a long-term engagement by the NGO Make Africa Better to improve the production of shea butter in the village. The facilities are built in cooperation with volunteers from the village and the resulting structures are owned locally.

Global Holcim Awards Gold 2018 goes to “Hydropuncture”, a publicly accessible water retention and treatment complex in Mexico. The project team is led by design director Loreta Castro Reguera at Taller Capital, and researcher Manuel Perló Cohen from the Universidad Nacional Autónoma de México. The infrastructure project in an underprivileged area of Mexico City intermingles flood basins and public amenities with spaces that follow the gravitational logic of flowing water. The jury stated that the sophisticated design addresses an urgent issue at a scale with real impact.

“Legacy Restored”, the Awards Silver winner, is a religious and secular complex in Niger that reinterprets traditional local construction for a new mosque and a community center. The project was designed by architects Mariam Kamara, atelier masomi, Niger; and Yasaman Esmaili, studio chahar, Iran. It creates a civic space open to all in the village of Dandaji, supporting the education of women and strengthening their presence within the community. The design strategy champions local artisanship, traditional building techniques and materials produced on site.

The community-driven neighborhood planning project “Grassroots Microgrid” wins Awards Bronze for re-imagining empty lots as collective infrastructure for energy and food production as well as for civic engagement in Detroit, USA. The large team of authors is led by Constance C. Bodurow, founding Director of studio[Ci], a transdisciplinary design collaborative in Detroit. The project enables neighborhoods to reach energy autonomy through micro-infrastructure, leverages vacancy as an asset, and creates a new economic paradigm for community renewal.

The strength of sustainable design

Jury head Alejandro Aravena commented that the global Gold and Silver winning projects act as role models: “They are masterful pieces that demonstrate what sustainable design and construction can achieve. As a community-driven initiative, the Bronze winner opens a path, innovating an approach that will need to be developed further,” said Aravena. The global Awards winning teams are diverse in every sense of the word. “Although not something considered during the evaluation process, the jury was delighted by the strong representation and success of women in the Holcim Awards,” said Aravena. Traditionally, the Awards competition enjoys a strong level of both participation and success in the competition by female professionals and students.

Aravena explained that the jury selected the water treatment project in Mexico for Gold because it builds large urban infrastructures that serve multiple purposes and become civic spaces. “Using architecture to give dignity to fragile rural communities losing population to urban migration, was a main reason for awarding Silver to the project in Niger," said Aravena. The Bronze winning project in the USA, finally, uses light and local infrastructure as a means of community building. “The context of the three global Awards winning projects is complementary, providing models for megacities, urban communities, and remote rural villages,” added Aravena: “They indicate two tendencies within the discourse on sustainability: a focus on infrastructure and new explorations of traditional ways of building.”

Prizes for exciting ideas in Argentina, Ghana and the USA

For the first time, the global Awards jury selected three of the 40 Acknowledgement and Next Generation prize-winning projects from the regional phase of the competition to receive Holcim Awards Ideas prizes. “We felt that they offer exciting and novel ideas, even within proposals that are not yet fully developed,” said jury head Alejandro Aravena. The prizes go ex aequo to “Refrigerating Jar” in Ghana, “Cooling Roof” in California, USA, and “Territorial Figure” in Argentina.

Architects Wonjoon Han and Gahee Van of VHAN together with Sookhee Yuk from Make Africa Better led a South Korean team designing shea butter storage towers in Nyingali, Ghana; they enable passive cooling that enhances the economic viability of agriculture and an aesthetic that alludes to traditional local architecture. Georgina Baronian, student at Princeton University in the USA, developed a prototype of a large-scale structure using water on the roof as a thermal insulator and solar reflector in one. The infrastructure-landscape project for the generation of electric power based on tidal currents at Punta Loyola in Argentina was developed by three students from the Universidad Nacional de Córdoba in Argentina: Stefano Romagnoli, Juan Cruz Serafini, and Tomás Pont Apóstolo.

From more than 5,000 submissions down to 6 global winners

The 5th International Holcim Awards competition attracted 5,085 projects and visions to be implemented in 131 countries. 1,836 projects passed the formal and quality checks and were assessed by independent juries in five competition regions: Europe, North America, Latin America, Middle East Africa and Asia Pacific. 11 prizes carrying a total of USD 330,000 per region were handed-over to winning teams in 2017. The three main winners per region automatically qualified for the global Awards; and the 40 Acknowledgement and Next Generation prize-winners were eligible for the Awards Ideas prizes 2018. The prize pool for the global phase of the Awards totals USD 350,000. The International Holcim Awards cycle spans three years, the 6th competition will open for entries in mid-2019.

Resource and environmental performance – Planet

Construction materials are eco-friendly and locally accessible. And the way of building type will follow the local construction method in Northern Ghana. The locally-built structure with a local construction material would not harm the environment. Mud bricks and cement bricks can be made anywhere. Masonry is the basic construction method that can be done by local labor. Therefore, this storage will be built with basic local construction material and method. The storage functions itself without any further extension work. It can be highly appropriate for the area which has a dry and higher temperature such as Northern Ghana. It purposes to emit zero percent of CO2 by reducing the negative effect on the environment.

Contextual and aesthetic impact - Place

Existing buildings are weak at external environments such as temperature and moisture. The new building can overcome those limitations under the same conditions. The building does not require any further external support and it is eco-friendly, sustainable, and energy saving. The building will be the center of the community and it will be a place to work and rest for women and a playground for children. This place will function as a meeting point and festival place for the community. The building and its courtyard can be a plaza for different events. For short term, this is to store food and shea butter for its freshness which is crucial for quality. For the long-term purpose, it provides new residence types for African. A pleasant and improved quality of residence provides quality of life.
