The new campus for environmental studies in Acatitlán, 140 km west of Mexico City will trigger a local regeneration process, reinforcing communities throughout the region. The project’s design for the Universidad del Medio Ambiente is locally attuned, self-sufficient regarding energy and water, promotes on-site food production, and will be realized with low-impact materials to minimize the architecture’s ecological footprint. Rather than promoting efficiency for efficiency’s sake, the authors frame the university curriculum based on local knowledge: “It’s not about the campus, it’s about a community.” Erected in three phases, the buildings are organized around a series of courtyards. Construction assemblies include stone foundations, wooden structures and wall finishes made of soil. The result is a sustainable and regenerative project, a “living classroom” that could readily be replicated.
