Buildings are not uniform.
The same building is not stressed the same way everywhere. One side gets rain. Another gets direct sun. Another stays shaded and damp. Floor 12 near a hot-water riser ages differently from a top-floor corner.
Yet "building maintenance" is still mostly answered at the building level — periodic inspections, generic schedules, reactive tickets. We think the unit of analysis should be the zone and the component, not the building.
