The Vocational Training Building in Zaragoza (Spain) applies a sustainable, site-responsive design. Positioned east-west, it engages the Juslibol canal and green spaces. A central courtyard carved diagonally enhances solar gain and spatial richness. Subtractive volumetry adapts to climate, shielding from western sun and opening eastward. Programmatic layers follow use frequency. Native gardens, green roofs, and rainwater systems support resilience. Brick and ceramics link tradition with low-impact design, meeting ECCN (Nearly Zero Energy Building) standards for regenerative urban development.
