The secondary school in Gando village, Burkina Faso uses traditional building materials and technologies and places great emphasis on actively involving the local population in the construction process. Locally-sourced clay is mixed with aggregates and cement to cast walls on-site based on a two-piece formwork. The school is exemplary in terms of its successful approach to the adaptive use of building materials, community development, climatic mitigation and aesthetics.
The challenge of this project is to remain effective in a zone of political tension in addition to addressing climatic and local constraints. The refurbishment of the Abu Hindi Primary School of the Bedouin community is located near Al Azarije (Eizariya), and less than 10km east of Jerusalem. The first phase of the restoration project was completed by September 2012 and achieves climatic comfort and energy sustainability by improving natural ventilation.
The design approach for the Teaching and Training Center Chwiter in the Marrakesh satellite suburb of Chwiter concentrates on the use of nearby resources including the workforce and earth as the primary construction material. These principles are enhanced by combining design-inherent shading and natural ventilation with modern technologies such as heat pumps and solar panels all of which enable low energy requirements in both construction and operation.
This materials development project succeeded in processing agricultural waste into low-cost construction panels bonded with tannin-based adhesive. Plant-based agricultural wastes from the cultivation of rice, maize and cassava crops provide natural fibers that are a sustainable resource for the production of building materials to achieve a reduction in construction costs, reducing dependence on imported, higher-cost alternatives.
The Swiss Village Sprinter Building project located in the exceptional Masdar concept city in Abu Dhabi integrates itself into a larger surrounding that claims sustainability as precondition. All steps of the design technique integrate state-of-the-art computer aided simulation processes where, for example, building shape is optimized to use the prevailing winds for natural ventilation and minimize solar gain.
Located in the UNESCO world heritage Cape Floral Region, the Oudebos Mountain Camp replaces an existing facility and aims to provide reconcilable facilities for sensitive eco-tourism. The project was officially opened in February, 2012, and consists of five self-catering cabins and a small function room which are lightweight, stilted structures that integrate modestly into the surroundings.
The underlying goal of the Place Lalla Yeddouna project is to revitalize an historic hub in the urban structure of Fez’s UNESCO World Heritage medina (old town) with new constructions and cautious conservation of valuable historic buildings. The urban design embraces the previously negated river and renders it a determining urban element offering space along the river for social interaction.
The Vertical Agriculture at the Old Pretoria West Power Station project transforms a soon to be decommissioned coal bunker of a power station into a vertical hydroponic garden, thereby inverting the attributes of a former polluting facility into a purifying element that continues to be a mechanism for supply of the city’s needs. Grey- and rain-water is used to grow food in close proximity to the urban consumer.
Helix structures 100m in diameter made of concrete and steel are positioned into the Nile River canyon. With 90% of the water and 96% of the transported sediment carried by the Nile originating in Ethiopia, the agricultural system collects the fertile soil the river carries during the flood season. Computer analysis of water flows and dynamics optimize the capture of sediment onto the structure. During the dry season, the towers emerge from the water and lay open the soil for cultivation.
The abandonment of Agadir’s Inbiaât Stadium has drained the lifeblood of the precinct and initiated the idea to redevelop the adjacent wasteland in between the beach and the city center. The result is the Agadir Connection concept to support urban development and upgrade facilities on the fringe of the city center. Architectural, landscaping and urban design interventions transform the previous transit space into an attractive living zone and space to rest.
The winners of the 3rd International Holcim Awards competition for sustainable construction projects and visions from Africa Middle East have been announced at a ceremony in Casablanca.
A total of USD 300,000 was presented to ten outstanding projects.
