ASET vs RSET: The Inequality Behind Every Evacuation Plan

ASET vs RSET decides whether a building passes. Here come the timeline, the tenability limits, the equations, and the one term that swings the answer most.

Wide cinematic cutaway photograph of a tall office tower at night under a deep-blue winter sky with snow blowing past lit windows; inside, a single illuminated emergency stairwell runs the full height of the building like a glowing vertical spine, with faint pale arrows of rising air suggesting stack effect drawing upward through the shaft — calm, architectural documentary framing that shows why a stairwell pressurization system behaves so differently on the coldest night of the year
