评委评语

布基纳法索是非洲最贫穷的国家之一，并位于世界上最干旱的地带。因此，基础教育和合适的生活条件是通向可持续发展的主要问题。从这个方面来说，冈多的中学项目做出了杰出贡献，为其他的项目提供了指引。

学校的美感和新颖的建筑概念赢得了评审团一致的深刻印象。项目结合了当代世界和当地的施工方法，在社会和教育方面都很有影响力。房子的墙使用的是当地粘土和水泥的混合物。这个项目还展示了在极其炎热的天气条件下，建筑师是如何使用低科技、低能耗和低成本的概念。建筑整合的技术解决方案包括被动通风、地下降温，以及自动灌溉系统等。再造林、 绿化、 烟囱效应气流，以及双层屋顶和外墙是粘土建筑其他的一些重要的可持续组

1件。为了与不断扩大的沙漠做斗争并防止地面失水，雨水都被收集起来并集中存储用于灌溉这一地区新栽的树木。从材料和技术角度来看，冈多拉中学将在干旱的萨赫勒地区和世界各地所有发展中国家为可持续建筑树立一个新的榜样。

该项目不只是让人们见证了当地材料的潜力。由于社区人民参与了建造，项目的施工过程也被视作是知识的传递。当地人从中学到的新的建筑技能还可以重复使用并传授给他人。这种来自新学校附近居民的共同努力和对他们的现场培训大幅度地增加了社会家庭之间的凝聚力和整个社区的自力更生能力。

评审团高度褒奖这个项目是因为上述这些方面以及项目对未来的关注。这个学校项目的综合设计方法是对可持续建设5个要素的典型应用。它必将对发展中地区类似的尝试产生强烈的影响。

Jury Appraisal

Burkina Faso is amongst Africa's poorest countries and is situated in one of the hottest arid zones in the world. Hence, basic education and appropriate living conditions based on personal responsibility are dominant issues on the country's path to a sustainable future. Te secondary school in Gando is a lighthouse project providing outstanding contributions in this respect.

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 form-work. Te school also shows how a lowtech, 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 facades 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.

Te 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.

Te jury commended this project due to these multifaceted and future-oriented elements. The comprehensive approach to this school project is an exemplary 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.
