HQE certification, issued to buildings with high environmental quality in more than 25 countries, is especially suitable for Morocco. Through the continued efforts of Cerway, a subsidiary of Certivéa (CSTB Group) and Cerqual (Qualitel Group), HQE is the first environmental certification mark in the country. It covers four urban development projects, more than 1,500 housing units and 15 nonresidential building operations. This strong presence is a gateway to the rest of Africa, increasingly sensitive to sustainable construction. In 2017, Cerway certified projects in Tunisia, Algeria and West Africa.
