ANSI/ASHRAE/IES 90.1 §9.4 (Lighting Controls)

What it requires

Requires occupancy/vacancy sensing, automatic daylight-responsive control in daylight zones, automatic shutoff, and (in many spaces) automatic shade/fenestration control coordination. This engine documents the control devices and pathway for coordination; it does NOT perform the lighting power density (LPD) compliance calculation — that stays with the engineer of record.
