A university cafeteria designed for constant activity and large spaces
A university cafeteria is always bustling. Large open spaces, generous ceiling heights and a constant flow of people throughout the lunchtime service. At Gustave Eiffel University, this cafeteria had to cope with this daily intensity without becoming an acoustic or thermal challenge.
230 m² of hemp blocks for internal insulation
A total of 230 m² of concrete block walls were lined internally with 20 cm-thick IsoHemp hemp blocks. This bio-based solution was designed for a demanding shared space where acoustic performance and thermal regulation were key requirements of the specification. The project was designed by Dialog Architecture, under the direction of Aurélien and Georgia Crozet, and carried out by Boisseau.
The sanitary facilities received a specific treatment: hemp blocks combined with a PCS (vapour barrier or additional layer according to the project specifications) and a tiled finish to meet the hygiene requirements of these areas.
Everyday comfort in use
The acoustic comfort has noticeably changed the atmosphere of the space. Conversations are clearer and the overall noise level has been reduced, a significant improvement in a space used by hundreds of people every lunchtime. The thermal regulation provided by hemp concrete is also evident: despite the continuous heat generated by a busy commercial kitchen, the cafeteria maintains a stable indoor environment, a benefit appreciated by its users.
