**Mandatory Rule:** False
**Rule ID:** 10-1
**Schema Version:** 0.0.36
**Mandatory Rule:** False
**Rule ID:** 10-1

**Rule Description:** The proposed design includes humidification and the baseline building design has been modeled with adiabatic humidification if proposed design does not comply with 90.1-2019 Section 6.5.2.4 and non-adiabatic humidification otherwise.

**Rule Assertion:** B-RMR = expected value
**Rule Assertion:** Options are UNDETERMINED/NOT_APPLICABLE
**Appendix G Section:** Section G3.1-10 HVAC Systems for the baseline building
**Appendix G Section Reference:** None
**Data Lookup:** None
**Evaluation Context:** Evaluate each HeatingVentilationAirAconditioningSystem
**Evaluation Context:** Evaluate each Zone

**Applicability Checks:**

**Rule Assertion:**
- Case 1: If the zone was modeled with humidification in the baseline and proposed then UNDERTERMINED (provide the zone_p.id and zone_b.id in the output): `if has_humidification_b == TRUE and has_humidification_p == TRUE: outcome == "UNDETERMINED" and raise_message "This zone is modeled with humidification in the baseline and proposed.

- Case 1: If the zone was modeled with humidification in the baseline and proposed then UNDETERMINED to check that the correct type of humidification was modeled (provide the zone_p.id and zone_b.id and the humidification_type_b in the output): `if has_humidification_b == TRUE and has_humidification_p == TRUE: outcome == "UNDETERMINED" and raise_message "This zone is modeled with humidification in the baseline and proposed.
