A series of events in West Africa celebrating the Global Holcim Awards Gold project, Secondary school with passive ventilation system, by Diébédo Francis Kéré included an enthusiastic reception at the school site in Gando, Burkina Faso as well as a media conference in the capital Ouagadougou and a presentation in Accra, Ghana. More than 3,000 community members including around 1,000 school children, representatives of regional and local authorities, politics, and religion enjoyed a village festival to celebrate the global Holcim Awards gold prize won by the school and to congratulate Diébédo Francis Kéré.
The reception began with a greeting by a village elder and a guard of honor by school students to welcome guests to the village of Gando, about 200km from the capital Ouagadougou. The gold trophy was presented in front of the building which is currently under construction and was followed by an evening of food, traditional dances, music and singing.
The prize hand-over included speeches by local dignitaries and a student representing the Gando school; Rolf Soiron, Chairman of the Holcim Foundation and Chairman of Holcim; Edward Schwarz, General Manager of the Holcim Foundation; and prize-winning architect, Diébédo Francis Kéré.
“If the state cannot help, we must help ourselves,” explained Diébédo Francis Kéré, emphasizing priority of school construction above the purchase of consumer goods such as televisions.
“The seeds we plant today are that which will be harvested tomorrow”, stated Rolf Soiron. “The grandchildren of the community that has built the school will still remember the Gando school initiative in years to come.” He further commented that architects should not be blind to the challenges of urbanization, demography, environment, equity, economics, nor the value of beauty.
“The Holcim Foundation is proud to present the gold award to this project, and honor the commitment of the team from Kéré Architecture and the Gando community to engage in sustainability beyond construction,” commented Edward Schwarz. “We also acknowledge that Diébédo Francis Kéré has allocated all prize money received from the Holcim Awards competition to the project – and is living proof that education is the basis for a brighter future.”
Before the celebration event in Gando, project author Diébédo Francis Kéré attended a media conference and a prize-handover reception in Ouagadougou – where he challenged African architects to make use of the abundant materials and human resources at their disposal to create contemporary eco-friendly and community-based architecture without compromising quality. The media event attracted some 30 journalists in addition to invited guests including the Ambassadors of Belgium and the USA, and diplomatic representatives from Algeria, the European Union, and the United Kingdom.
The prize-handover was conducted by architect Joe Osae-Addo, Chairman of ArchiAfrika and member of the Holcim Awards jury for Africa Middle East, together with Rolf Soiron. Joe Osae-Addo explained the significant contribution of the project to sustainable construction. “The school project uses a hybrid building technique and was praised for creating a remarkable environment both from a social and constructive point of view,” he said.
The winner of the prize is Berlin-based architect Diébédo Francis Kéré, himself a son of the village headman of Gando where his latest school complex for more than 1,000 children is being constructed. The project combines traditional building materials and new technologies and utilizes a cement-stabilized reinforced cast earth process. The approach places great emphasis on actively involving the local population in the construction process.
The series of events in Africa to celebrate the gold award will conclude with a lecture on the Gando school project in Accra, Ghana hosted by ArchiAfrika. The event has attracted more than 100 guests including the Deputy Minister of Education of Ghana, and will be steamed via the Internet to the partner universities of ArchiAfrika across the continent.See more
The secondary school in Gando is a lighthouse project providing an outstanding contribution to the dominant issues on the country’s path to a sustainable future. The jury was unanimously impressed by the school’s beauty and its innovative architectural concept, which combines both modern and vernacular construction methods, as well as by its social and educational impact. Locally-sourced clay is mixed with aggregates and cement to cast walls on-site based on a two-piece formwork.
The jury was unanimously impressed by the school’s beauty and its innovative architectural concept, which combines both modern and vernacular construction methods, as well as by its social and educational impact. Locally-sourced clay is mixed with aggregates and cement to cast walls on-site based on a two-piece formwork.
The school also shows how a low-tech, energy saving and low-cost climatic concept can be used in extremely hot weather conditions. Technical solutions including passive ventilation, underground cooling, and automatic irrigation are integrated into the architectural solution. Reforestation, greenery, stack-effect air currents, and double-skin roofs and façades are other important sustainable components of the clay building. To fight against the ongoing expansion of the desert and to prevent the dehydration of the ground, rainwater is captured and centrally stored for irrigating the newly-planted trees in the area. From a materials and technology perspective, the secondary school in Gando will set an example for new sustainable construction – not only in the arid Sahel, but in all developing regions around the world.
The project provides more than just a testament to the potential of locally-sourced materials. Built by the community, the construction process is considered to be an important part of the transfer of knowledge, whereby locals acquire new building skills that can be reused and taught. This common effort and on-site training of the residents in the vicinity of the new school substantially increases social cohesion among families and self-reliance of the whole community.
The jury commended this project due to these multifaceted and future-oriented elements. The comprehensive approach to this school project is an exemplarily application of sustainable construction according to the five “target issues” for sustainable construction of the Holcim Foundation, and will have an undoubtedly strong impact on similar endeavors in developing regions.See more
The secondary school in the village of Gando in Burkina Faso was selected to receive the Global Holcim Awards Gold 2012 out of more than 6,000 competition entries from all over the world. Speakers at the prize handover held at the iconic Rolex Learning Center of the EPFL Lausanne, Switzerland included internationally-renowned architect Enrique Norten, EPFL president Patrick Aebischer, and Holcim Chairman Rolf Soiron. The project was praised for its approach to using traditional building materials and technologies that also places great emphasis on actively involving the local population in the construction process.
The Global Holcim Awards Gold 2012 was presented to Berlin-based architect Diébédo Francis Kéré, himself a son of the village headman of Gando where his latest school complex for more than 1,000 children is being constructed. The architect needed to convince the locals of the durability and strength of clay which is poured and cast similar to concrete, improving its structural performance by adding a small proportion of cement.
The approach uses clay and stones that are collected from land adjacent to the village, and introduces new and more sustainable construction techniques. Diverse design aspects of the project address the challenging weather conditions with temperatures peaking above 40°C. For the interior climate, the natural ventilation cooling effect is enhanced by routing air through underground tubes, planting vegetation, and the use of double-skin roofs and façades to achieve a remarkable temperature reduction.
Enrique Norten, Principal and Founder of TEN Arquitectos, and head of the Global Holcim Awards jury (Mexico/USA), explained the exemplary nature of the project in terms of its successful approach to the adaptive use of building materials, community development, climatic mitigation and aesthetics. “This beautiful school is not only an elegant design solution, but it also delivers training and employment, uses local building materials, and – with simple means – creates an outstanding environment from a social perspective and also in constructive terms,” he said.
Chairman of the Steering Committee of the Holcim Foundation and CEO of Holcim, Bernard Fontana, congratulated the prize winner and his team for applying professional know-how and passionate dedication to developing an approach that is both socially-engaged and intelligently leverages the local human and physical resources. “The Secondary School Gando is constructed by the local community and builds not only a series of structures, but also a sense of identity and enhanced social cohesion,” he said.
Diébédo Francis Kéré presented his winning project to an audience including students of architecture and engineering from the Swiss Federal Institute of Technology in Lausanne (EPFL). The engaging talk clearly conveyed his personal commitment to his work in different cultures and its potential benefits to the community. With regard to the winning project he said: “The enhanced indoor comfort and conditions are far more conducive to education for the students – while at the same time people learn building skills using clay and other readily available local materials, which strengthens the idea of a mutually-beneficial process since the skills learnt can be applied beyond the confines of the site.”
In the regional phase of the Holcim Awards 2011, this project won gold for Africa Middle East and thereby qualified for the Global Holcim Awards competition in 2012.
The Holcim Awards competition is run by the Swiss-based Holcim Foundation and offers USD 2 million in prize money per three-year cycle. It is sponsored by Holcim Ltd, one of the world’s leading suppliers of cement and aggregates, and its Group companies in 70 countries. The next Holcim Awards competition will open on July 1, 2013.
Architects Francis Kéré (Kéré Architecture) and Eike Roswag (Ziegert | Roswag | Seiler) fascinated 200 guests with presentations of their two school projects that are under construction in Burkina Faso and Pakistan – both projects use traditional building materials and technologies and place great emphasis on actively involving the local population in the construction process.Read more »
The exhibition “MACHEN!” (to make) at the AEDES Network Campus follows the development process of six projects including the Secondary school with passive ventilation system. All six projects are examples of a new, reflective approach to the topic: for a building to be truly sustainable, architects must use their own creative and conceptual skills – where technology is employed not for its own sake, but as a means to a well-executive series of objectives.Read more » lesen Sie mehr: MACHEN!

Construction of the next phase of the project to complete the secondary school is progressing to schedule in mid-2012. This school project in one of the world’s poorest countries aims to provide further education to the inhabitants of a rural area. Gando, with a population of 3000, has no secondary education facilities and lies on the southern plains of Burkina Faso, some 200km from the capital Ouagadougou.
A school project in Burkina Faso that integrates social and environmental performance won the top prize of USD 200,000. The design for the school in the village of Gando was created by Diébédo Francis Kéré of Kéré Architecture in Berlin. Passive cooling during oppressive summer heat creates an indoor climate conducive to learning by routing air through subterranean tubes, planting vegetation, stack-effect air currents, and using double-skin roofs and façades. The project also improves social conditions by providing jobs and training, and restores the environment through reforestation.Read full media release – Global Holcim Awards 2012 » leia mais: Projeto de revitalização de favela no Brasil recebe prêmio em construção sustentável (Portuguese) » más información: Los premios máximos de la construcción sustentable fueron entregados a propuestas en Burkina Faso, Brasil y Alemania (Spanish) » pour en savoir plus: Des projets au Burkina Faso, au Brésil et en Allemagne remportent les premiers prix dans la construction durable (French) »
The projects that received Holcim Awards Gold, Silver, or Bronze in each of the five regions of the world were automatically qualified to compete for the Global Holcim Awards 2012.

The jury commended this project because of its broad approach towards enmeshing discreet sustainable aspects of the program into a comprehensive whole. The Secondary School Gando is constructed by the local community and builds not only a series of structures, but also a sense of identity and enhanced social cohesion. Its “urban design” has the potential to act as an anchor point in the village structure. The project, as one element of a long-term school development, makes use of “high-tech” ideas that are implemented with low-tech means. It intelligently leverages the site’s characteristics and locally-available materials.
The project itself generates positive impacts upon both the social environment by generating opportunities for education, creating jobs and training; and on the natural environment through reforestation. People learn building skills using clay and other readily available local materials, which strengthens the idea of a mutually-beneficial process since the skills learnt can be applied beyond the confines of the site. The experiences and techniques partially applied to earlier projects realized independently on the same site were integrated, and prove the potential and applicability of the project’s inherent ideas.See more
The school project that uses only solar and wind power to cool the classrooms won the top prize of USD 100,000. The design for the secondary school in the village of Gando on the dry tropical savanna was created by Berlin-based architect Diébédo Francis Kéré, of Kéré Achitecture, who was the first person from the village to study internationally, and is also the son of the village headman.Read full media release – Holcim Awards 2011 for Africa Middle East » أقرأ المزيد: عن مشاريع "هولسيم أوارد" Holcim Awards الفائزة في منطقة إفريقيا و الشرق الأوسط (Arabic) » pour en savoir plus: Projets de construction durable pour l’amélioration des communautés (French) »
The project aims for the sustainable use of resources to provide natural ventilation without any use of electricity. The natural ventilation system works with low-tech, cost-effective earth-tubes, which is a sustainable, zero-energy passive geothermal solar cooling system. The school will provide graduate students accessibility to further education and therefore enhances the sustainability of the educational opportunities created.
The extremely hot weather make studying in buildings without air-conditioning very difficult. That is why all interior spaces are embedded partially underground in the redesigned landscape to create a shadowed oasis. Due to the massive deforestation which has taken part in the past, the region is now facing the expansion of the desert. To prevent the dehydration of the ground, collected rainwater irrigates the recently planted trees around the existing school buildings. The reforestation is continued in the Secondary School Gando and creates leisure space.See more Download project entry poster (PDF, 1.86 MB) »
