**Appendix G Section:** Section G3.1-6 Modeling Requirements for the Baseline

**Applicability:** All required data elements exist for B_RMR
**Applicability Checks:** None
**Applicability Checks:** Space function is not crawl space, plenum or interstitial space.
**Manual Check:** No

**Evaluation Context:** Each Data Element

## Rule Logic:

- For each building segment in the baseline model: `building_segment_b in B_RMR.building.building_segments:`
- For each building segment in the baseline model: `building_segment_b in B_RMD.building.building_segments:`

- Get matching building segment in R_RMR: `building_segment_p = match_data_element(P_RMR, BuildingSegments, building_segment_b.id)`
- Get matching building segment in P_RMD: `building_segment_p = match_data_element(P_RMD, BuildingSegments, building_segment_b.id)`

- Get lighting status type dictionary for P_RMR: `space_lighting_status_type_dict_p = get_lighting_status_type(building_segment_p)`
- Get lighting status type dictionary for P_RMD: `space_lighting_status_type_dict_p = get_lighting_status_type(building_segment_p)`

- For each thermal block in building segment: `thermal_block_b in building_segment_b.thermal_blocks:`

- For each zone in thermal block: `zone_b in thermal_block_b.zones:`

- For each space in zone: `space_b in zone_b.spaces:`
- **Applicability Check:** Check if the space is a crawl space, plenum or interstitial space: `if space_p.function in [PLENUM, CRAWL_SPACE, INTERSTITIAL_SPACE]:`
- Rule is not applicable because space function is crawl space, plenum or interstitial space: RULE_NOT_APPLICABLE: `continue`

- For each space in zone: `space_b in zone_b.spaces:`
- Get total lighting power density in space: `total_space_LPD_b = sum(interior_lighting.power_per_area for interior_lighting in space_b.interior_lighting)`

- Get total lighting power density in space: `total_space_LPD_b = sum(interior_lighting.power_per_area for interior_lighting in space_b.interior_lighting)`
- Get lighting status type for space: `space_lighting_status_type = space_lighting_status_type_dict_p[match_data_element(P_RMR, Spaces, space_b.id).id]`

- Get lighting status type for space: `space_lighting_status_type = space_lighting_status_type_dict_p[match_data_element(P_RMR, Spaces, space_b.id).id]`
- Check if lighting space type is specified, get lighting power density allowance from Table G3.7: `if space_b.lighting_space_type: LPD_allowance_b = data_lookup(table_G3_7, space_b.lighting_space_type)`

- Check if lighting space type is specified, get lighting power density allowance from Table G3.7: `if space_b.lighting_space_type: LPD_allowance_b = data_lookup(table_G3_7, space_b.lighting_space_type)`
- Else, lighting space type is not specified, assume "Office-Open Plan" as lighting space type to get lighting power density allowance from Table G3.7: `else: LPD_allowance_b = data_lookup(table_G3_7, "OFFICE-OPEN PLAN")`

- Else, lighting space type is not specified, assume "Office-Open Plan" as lighting space type to get lighting power density allowance from Table G3.7: `else: LPD_allowance_b = data_lookup(table_G3_7, "OFFICE-OPEN PLAN")`

**Rule Assertion:**
- Case 1: If space lighting status type is as-designed or as-existing, and lighting space type is not specified: `if ( space_lighting_status_type == "AS-DESIGNED OR AS-EXISTING" ) AND ( NOT space_b.lighting_space_type ): FAIL and raise_warning "P_RMR LIGHTING STATUS TYPE IS AS-DESIGNED OR AS-EXISTING.
