第25条组织正在尼日尔使用美丽的红土石重建一所学校 – 第25条组织是一个人道主义建筑慈善机构,专注于设计和帮助在世界最需要的地方建设教育和医疗项目。尼日尔的教育系统面临着巨大的挑战。该国是世界上出生率最高的国家(平均每个妇女生7个孩子),同时也在努力将年轻人留在教育系统中,特别是小学以上的教育。

Article 25 are redeveloping a school in Niger using beautiful laterite stone – Article 25 are a humanitarian architecture charity with a focus on designing and helping to build education and healthcare projects in parts of the world that needs them most. Niger’s education system faces huge challenges. The country has the highest birth rate in the world (~7 children born to every woman on average), and simultaneously struggles to keep young people in the education system, particularly beyond primary schooling.

第25条与尼日尔的Hampaté Bâ学院合作,设计新的教室和相关设施,使该学院能够容纳1200名从小学到高中的儿童。该学院的建议包括翻修现有的教室和增加5个新的教室区(共20个教室),以及新的行政设施、礼堂、图书馆和厕所区。为了提高学校对间歇性市政供应的适应能力,还建议对水和电力服务进行升级改造。

Article 25 have been working with Collège Hampaté Bâ in Niger to design new classrooms and associated facilities that will enable the college to accommodate up to 1,200 children from primary school age through to lycée. The proposals for the college include refurbishment of existing classrooms and the addition of 5 new classroom blocks (totaling 20 classrooms), along with new administrative facilities, assembly hall, library and latrine blocks. Upgrades to water and electrical services are also proposed in order to improve the school’s resilience to the intermittent municipal supply.

用可持续的红土石建造–设计优先考虑使用当地材料,采用当地技术来应对具有挑战性的气候条件,并创造有利于学习的美丽、舒适的空间。主要的建筑材料是红土石;这是一种廉价的、可在当地获得的、低碳的材料,代表了尼日尔的一种未被充分利用的资源。红土石提供热质,减缓白天的热量释放,而且比尼亚美现代建筑中无处不在的水泥块更透气。

Built from sustainable laterite stone – The design prioritizes the use of local materials, adapting vernacular techniques to respond to the challenging climatic conditions and create beautiful, comfortable spaces conducive to learning. The principal building material is laterite stone; a cheap, locally available material with low embodied carbon, which represents an underutilized resource in Niger. Laterite provides thermal mass to slow the release of heat during the day and is a more breathable material than the cement blocks that are ubiquitous in modern construction in Niamey.

红土是在尼亚美10公里外的采石场用手挖出来的,与空气接触后变硬,适合建筑使用。在施工过程中,当地泥瓦匠接受了如何使用红土的培训,目的是为了在该地区的其他项目中传播这些技能。第25条还为对建筑业感兴趣的年轻女孩发起了一个现场培训项目。

Laterite is dug from the ground by hand in a quarry 10km outside Niamey, and hardens on contact with air to become suitable for building. During construction, local masons have been trained in how to use laterite, with the intention that the skills can be disseminated in further projects around the region. Article 25 have also initiated an on-site training program for young girls interested in the construction industry.

被动式通风使教室保持凉爽 – 建筑物采用被动式设计原则来缓解高温,并为教学和学习创造舒适的空间。尼亚美的气候极具挑战性,白天的温度全年都在30多度,在温暖的月份经常达到40度以上。空调是昂贵而不可靠的,因此采用了被动式设计策略,以尽可能减少空调的使用。

Passive ventilation keeps the classrooms cool – The buildings use passive design principles to mitigate the high temperatures, and create comfortable spaces for teaching and learning in. Niamey’s climate is extremely challenging, with daytime temperatures in the 30s all year round, and regularly reaching well above 40 degrees in the warmer months. Air conditioning is expensive and unreliable, and a passive design strategy has been employed to reduce its use as far as possible.

教室的设计采用了由Francis Kere推广的双层屋顶系统。教室天花板上的土砖拱顶,上面是轻质的飞行金属屋顶。屋顶的角度和建筑的方向有助于将空气拉过屋顶的空腔,这意味着太阳的热量不会被辐射到房间里。事实证明,这种被动式设计策略是非常成功的。通过测量几个月的温度数据,我们观察到,即使教室里坐满了40个学生,教室里的温度也明显比外面低,温度通常为7-8度。

The classrooms have been designed with a double roof system popularized by Francis Kere. Earth brick vaults from the classroom ceiling, with a lightweight flying metal roof above. The roof angle and building orientation help pull air through the roof cavity, meaning the sun’s heat is not allowed to radiate into the rooms. The passive design strategy has proved a great success. By measuring temperature data over several months, we have observed that even when filled with up to 40 students the classrooms stay significantly cooler than outside, with temperatures typically 7-8 degrees
