# B1 — Trend-log strategy (per Op#11)
metadata:
  project: Kingsford Hotel Bacolod — BMS
  date: 2026-04-28

# Per I/O class trend-log enrollment percentages.
# Hospitality (no casino regulatory overlay).
ai_pct: 100   # all analog inputs trended (control-loop tuning + energy reporting)
ao_pct: 100   # all analog outputs trended
di_pct: 30    # status/HOA/trip — most are abundant boolean signals rarely reviewed; trend only equipment-status DI groupings
do_pct: 100   # commands trended (1:1 with AO control)
hli_pct: 70   # equipment HLI subpoints — trend energy/control points (kW, current, valve position) but not vendor diagnostic detail (e.g., refrigerant temps from chiller — already on chiller's own log)

basis: "Hospitality trend-strategy — comfort and energy driven, not regulatory like healthcare/casino. AI/AO/DO trended 100% for control-loop tuning and energy reporting. DI lowered from legacy 40% to 30% because hotel status DIs (HOA, run, trip) are abundant and most are alarm-only — full trend enrollment is operational noise. HLI 70% covers energy/control subpoints; vendor diagnostic detail (e.g., refrigerant pressures already logged at the chiller) excluded."
