Since the autumn of 2017, students in the first and second year of secondary school in Binche have been the first students in Belgium to take their classes in a timber-framed building insulated with straw. The wooden frame structure comprises two floors with eight classrooms. The walls were insulated with compressed straw bales lined with a layer of clay, which ensures optimum air humidity. These two materials, sourced from local industries, only require a small amount of energy to be produced and contain no potentially toxic substances. The floor of the building is constructed from a cork layer. The entire project was delivered in July 2018.
