Envelope - Rule 5-18

Schema Version 0.0.23
Primary Rule: False Rule ID: 5-18
Rule Description: Manually controlled dynamic glazing shall use the average of the minimum and maximum SHGC and VT. Appendix G Section: Section 5 Envelope
Appendix G Section Reference: Section G3.1-5(a)5 Building Envelope Modeling Requirements for the Proposed design

Applicability: All required data elements exist for P_RMR
Applicability Checks:

  1. The proposed building uses manually controlled dynamic glazing

Evaluation Context: Each Data Element
Data Lookup: None
Function Call: None

Rule Logic:

  • For each building segment in the Proposed model: for building_segment_p in P_RMR.building.building_segments:

    • For each zone in building segment: for zone_p in building_segment_p.zones:

      • For each surface in zone: for surface_p in zone_p.surfaces:

        • For each subsurface in surface: for subsurface_p in surface_p.subsurfaces:

        Rule Assertion:

        • Case 1: If subsurface has manual dynamic glazing, outcome is UNDETERMINED: if subsurface_p.dynamic_glazing_type == "MANUAL_DYNAMIC: outcome = UNDETERMINED and raise_message "SUBSURFACE ${subsurface_p} INCLUDES MANUALLY CONTROLLED DYNAMIC GLAZING IN THE PROPOSED DESIGN. VERIFY THAT SHGC AND VT WERE MODELED AS THE AVERAGE OF THE MINIMUM AND MAXIMUM SHGC AND VT."
        • Case 2: Else, outcome is NOT_APPLICABLE: else: outcome = NOT_APPLICABLE

Notes:

  1. Update Rule ID from 5-39 to 5-29 on 10/26/2023
  2. Update Rule ID from 5-29 to 5-18 on 12/22/2023
