This lecture discusses the concept of energy autonomy as demonstrated by a pavilion featuring a fully covered roof of photovoltaic panels. The pavilion achieves an impressive 90.7% energy autonomy, with a total consumption of 13.8 kWh/m2. The presentation highlights the pavilion's design, which includes terracotta-colored elements that harmonize with wooden features. It also addresses the life cycle analysis of the pavilion, confirming that its environmental impact during construction and operation remains within acceptable limits for 2050. The pavilion's architecture is designed to enhance the cyclical experience of light, guiding visitors through various spaces while emphasizing the relationship between light and the structure. The lecture concludes by inviting attendees to visit the sustainable pavilion on campus and experience its unique design and energy efficiency firsthand.
