BIPV Glass Integration: 10 Surfaces Beyond the Rooftop

BIPV Glass Integration: 10 Surfaces Beyond the Rooftop A modern glass tower is a strong candidate for solar glass on its walls, not only its roof. I. Why the Roof Is No Longer Enough Picture a 12-story office tower. The roof holds chillers, stair bulkheads, antennas, and a window-cleaning rig. After setbacks and fire access paths, very little roof is left for solar. The walls tell a different story. On many mid-rise and high-rise buildings, the facade has 1.5 to 3 times more surface area than the roof. That is the “roof space bottleneck.” It is the main reason net-zero targets often stall on paper. The shift from add-on solar […]
