Lemoal Lemoal建筑和景观设计事务所已经交付了法国第一个用麻混凝土块建造的新公共建筑,即为Croissy-Beaubourg镇建造的Pierre Chevet体育馆(77)。制造商、建筑师和建筑公司之间卓有成效的合作,是尝试创新和可持续实施的机会。

Lemoal Lemoal architecture and landscaping office has delivered the first new public building constructed with hempcrete blocks in France, the Pierre Chevet sports hall for the town of Croissy-Beaubourg (77). The fruitful collaboration between manufacturers, architects, and construction companies was the opportunity to experiment with an innovative and sustainable implementation.

麻和木的混合结构。该项目的结构原则是由采用具有多种性能的持久性材料的决心所引导的。木制的半拱形门廊,为运动练习腾出了最大的空间,靠着麻混凝土块的墙来支撑。选择这些麻混凝土块是因为它们具有许多舒适性–和增强安全性–的品质,其中包括它们的高热、声学和结构性能,以及防火性能(REI 30)。

Mixed hemp and wood structure. The project’s structural principle was lead by the determination to employ long-lasting materials with multiple performances. The wooden half-vaulted porticoes, which free a maximum of space for practicing sports, lean against a wall of hempcrete blocks for support. These hempcrete blocks have been chosen for their many comforts – and safety-enhancing – qualities, among which their high thermal, acoustical, and structural performances, and fire resistance (REI 30).


Hemp, a short supply chain. Made by the cement manufacturer Vicat, the hempcrete blocks chosen here are manufactured with hemp hurds, agricultural material obtained from hemp, which until now has been without a market. The fibers are from plants cultivated in France and then assembled at less than 500km from the project site. Durable, high-performance, and innovative, hempcrete and its use in building blocks boost the commercial value of short supply chains, mobilizing actors in France, from the farmer to the worker.


Finishing. Mostly employed in detached houses, hemp is generally treated with a finishing coat of plaster on the exterior. Here, to facilitate their upkeep, the façades are covered in cladding whose panels can be individually replaced. Lower sections of interior surfaces have been treated with hemp plaster. On the upper parts, the hempcrete blocks have been left exposed, thereby maintaining their acoustical qualities.
