The Evolution of Sustainability in Roofing: Understanding NSF/ANSI 347 Membrane Durability The 2021 revision replaces all prior
: Energy efficiency, water conservation, and waste management during production. Membrane Durability The classroom shifted from a static lecture hall

Pandemic pedagogy: learning in motion If the course dealt with systems—food systems, public-health systems, or technological systems—then 2021 offered a live laboratory. Students weren’t just reading case studies about disrupted supply chains; they were watching grocery shelves empty and reappear, tracking global shipping delays, and seeing how local farmers pivoted to CSA boxes and direct-to-consumer models. The classroom shifted from a static lecture hall to a patchwork of Zoom rooms, community partnerships, and fieldwork where safety protocols mattered as much as research methods.
