Sartrouville – School complex

A major educational facility, exemplary in environmental terms.

From 2025, the future Sartrouville school complex will accommodate more than 1,200 students from kindergarten to secondary school. With a budget of €80 million financed by the Yvelines department and the city, this project is part of an ambitious low-carbon construction approach.

An educational and environmental project

Designed by the Officina and GR Design agencies and built by Léon Grosse, GCC and a group of committed partners, the school complex stands out for :

• massive use of bio-sourced materials (wood and wood-based concrete),
• a biomass boiler and 100 kWp of photovoltaic roofing,
• green roofs, an educational garden, 80 planted trees and landscaped areas promoting biodiversity and rainwater management,
• high energy performance: level E3C1 of the E+C- label, consumption < 50 kWhef/m².an, heating requirements < 15 kWh/m².an.

The role of TimberROC® wood-based concrete

The project’s straight facades are made of prefabricated load-bearing walls in TimberROC® wood-based concrete (6000m²), produced at the Spurgin plant in Mignières (28).
This choice was made for :

• combine structural performance, summer comfort and acoustics,
• meet the requirements of the French RE2020 energy and carbon regulation and exceed level 3 of the Bâtiment Biosourcé label,
• enable rapid, safe implementation thanks to off-site construction, with components delivered just-in-time,
• to guarantee quality finishes and reduce on-site labor.
