 **Rule ID:** 12-2  
-**Rule Description:** Number of spaces modeled in User RMR and Proposed RMR are the same  
-**Rule Assertion:** Proposed RMR = User RMR  
-**Appendix G Section:** Section Table G3.1-12 Modeling Requirements for the Proposed design  
+**Rule Description:** Depending on the space type, receptacle controls may be required by 90.1 Section 8.4.2. Receptacle schedules shall be modeled identically to the proposed design except when receptacle controls are specified in the proposed design for spaces where not required by Section 8.4.2.  
+**Rule Assertion:** Baseline RMD = Proposed RMD  
+**Appendix G Section:** Table G3.1-12 Proposed Building Performance column  
 **Appendix G Section Reference:** None  
-
-**Applicability:** All required data elements exist for P_RMR and U_RMR  
-**Applicability Checks:** None  
-**Manual Check:** None  
-**Evaluation Context:** Each Data Element  
 **Data Lookup:** None  
+**Evaluation Context:** Each miscellaneous equipment load
 
-## Rule Logic:

-  - For each zone in thermal block: ```zone_user in thermal_block_user.zones:```
 
-  - For each space in zone, add to the total number of spaces in the User model: ```for space_user in thermal_zone_user.spaces: num_of_spaces_user += 1```

+## Rule Logic:  
+- Create a list of the lighting space types that correspond to space types that may have receptacle control requirements in Section 8.4.1: `EXPECTED_RECEPTACLE_CONTROL_SPACE_TYPES = ["OFFICE_ENCLOSED", "CONFERENCE_MEETING_MULTIPURPOSE_ROOM", "COPY_PRINT_ROOM", "LOUNGE_BREAKROOM_HEALTH_CARE_FACILITY", "LOUNGE_BREAKROOM_ALL_OTHERS", "CLASSROOM_LECTURE_HALL_TRAINING_ROOM_PENITENTIARY", "CLASSROOM_LECTURE_HALL_TRAINING_ROOM_SCHOOL", "CLASSROOM_LECTURE_HALL_TRAINING_ROOM_ALL_OTHER", "OFFICE_OPEN_PLAN"]`  
+- For each space in the baseline RMD: `for space_b in B_RMD.spaces:`  
+  - Get the lighting space type: `space_type_b = space_b.lighting_space_type`
+  - For each miscellaneous equipment load in the space: `for misc_equip_b in space_b.miscellaneous_equipment:`
+    - Get the corresponding miscellaneous equipment load from the proposed RMD: `misc_equip_p = match_data_element(P_RMD, MiscellaneousEquipment, misc_equip_b.id)`
+    - Get the baseline miscellaneous equipment load schedule: `misc_equip_schedule_b = misc_equip_b.multiplier_schedule`
+    - Get the proposed miscellaneous equipment load schedule: `misc_equip_schedule_p = misc_equip_p.multiplier_schedule`
+    - Get the baseline automatic receptacle control: `auto_receptacle_control_b = misc_equip_b.has_automatic_control`
+    - Get the proposed automatic receptacle control: `auto_receptacle_control_p = misc_equip_p.has_automatic_control`
+    - If it is a leap year, set the schedule comparison mask to 8784 hours, else set it to 8760 hours: `mask_schedule = [1] * 8784 if is_leap_year else [1] * 8760`
+    - Compare the baseline miscellaneous equipment load schedule to the proposed miscellaneous equipment load schedule: `comparison_data = compare_schedules(misc_equip_schedule_b, misc_equip_schedule_p, mask_schedule)`
