+# Lighting - Rule 6-10  
+
+**Rule ID:** 6-10  
+**Rule Description:** Lighting and miscellaneous equipment loads and schedules are modeled identically across the baseline and proposed for plenums, crawl spaces, and interstitial spaces.  
+**Rule Assertion:** Proposed RMD = Baseline RMD    
+**Appendix G Section:** Table G3.1 #1 Baseline Column  
+**Appendix G Section Reference:** None  
+
+**Applicability:** Spaces with a function defined as plenum, crawl space, or interstitial space.  
+**Applicability Checks:**  
+
+  1. Spaces with a function defined as plenum, crawl space, or interstitial space.
+
+**Manual Check:** None  
+**Evaluation Context:** Each Space  
+**Data Lookup:** None  
+
+**Function Call:**
+
+1. compare_schedules()
+2. match_data_element()
+
+## Rule Logic:  
+
+- For each space in the proposed RMD: `for space_p in P_RMD...Space:`
+
+  - **Applicability Check:** `if space_p.function not in [PLENUM, CRAWL_SPACE, INTERSTITIAL_SPACE]:`   
+    - RULE_NOT_APPLICABLE: `continue`
+  
+  - **Rule Logic:**
+  - Create boolean to track mismatch between baseline and proposed: `mismatch = False`  
+  - Match baseline space: `space_b = match_data_element(B_RMD, Spaces, space_p.name)`  
+  - If space not found then mismatch is TRUE: `if not space_b:`  
+    - mismatch = True: `mismatch = True`  
+    - No match found: `continue`  
+  - Index baseline lighting by ID: `baseline_lighting = {obj.id: obj for obj in space_b.interior_lighting}`  
+  - For each interior lighting object associated with space_p, compare each to baseline lighting object: `for lighting_p in space_p.interior_lighting:`  
+    - Get analogous baseline lighting object: `lighting_b = baseline_lighting.get(lighting_p.id)`  
+    - If lighting_b not found then mismatch is TRUE: `if not lighting_b:`  
+      - mismatch = True: `mismatch = True`  
+      - No match found: `continue` 
+    - Compare attributes: `        if (
+            lighting_b.purpose_type != lighting_p.purpose_type or
+            lighting_b.power_per_area != lighting_p.power_per_area or
+            lighting_b.occupancy_control_type != lighting_p.occupancy_control_type or
+            lighting_b.daylighting_control_type != lighting_p.daylighting_control_type or
+            not compare_schedules(
+                lighting_p.lighting_multiplier_schedule,
+                lighting_b.lighting_multiplier_schedule,
+                method="1 for all 8760"
+            )
+        ):`  
+      - Mismatch equals true: `mismatch = True`  
+  - Index baseline misc by ID: `baseline_misc = {obj.id: obj for obj in space_b.miscellaneous_equipment}`  
+  - For each misc equipment object associated with space_p, compare each to baseline misc object: `for misc_p in space_p.miscellaneous_equipment:`  
+    - Get analogous baseline misc object: `misc_b = baseline_misc.get(misc_p.id)`  
+    - If misc_b not found then mismatch is TRUE: `if not misc_b:`  
+      - mismatch = True: `mismatch = True`  
+      - No match found: `continue` 
+    - Compare attributes: `        if (
+            misc_b.energy_type != misc_p.energy_type or
+            misc_b.power != misc_p.power or
+            misc_b.sensible_fraction != misc_p.sensible_fraction or misc_b.latent_fraction != misc_p.latent_fraction or
+            misc_b.remaining_fraction_to_loop != misc_p.remaining_fraction_to_loop or
+            misc_b.energy_from_loop != misc_p.energy_from_loop or
+            misc_b.type != misc_p.type or
+            misc_b.automatic_controlled_percentage != misc_p.automatic_controlled_percentage or
+            not compare_schedules(
+                misc_p.multiplier_schedule,
+                misc_b.multiplier_schedule,
+                method="1 for all 8760"
+            )
+        ):`  
+      - Mismatch equals true: `mismatch = True`  
+
+  **Rule Assertion:**  
+  - Case 1: If no mismatch was found then PASS: `if not mismatch: PASS`  
+  - Case 2: if a mismatch was found then FAIL: `else: FAIL and raise_message "It is expected that lighting and miscelleneous equipment would be modeled identically across the baseline and proposed for plenums, crawl spaces, and interstitial spaces. A mismatch was observed for <include space id and the mismatches observed>" `   
+
+**Notes:**
+1. Could the interiorlighting and misc objects have different IDS across the baseline and proposed, if so how do we match them up ?  
+2. Need to add this rule to Workbook.
+3. Need to also add this to 90.1 2019.
