Abstract This study proposes a Level of Service (LOS)?based indicator framework to evaluate human?robot coexistence in buildings, extending assessment from static checklists to operational performance during building operation. Candidate measures were derived from pedestrian LOS and HRI/HRC literature and robot-inclusive building guidelines, and were refined through focus group interviews. The final framework comprises four domains?mobility/crowdedness, safety/collision, communication/acceptance, and interoperability, efficiency, and maintenance? and includes 12 indicators computable from robot and facility logs, video/LiDAR tracking, and user surveys. An expert panel (n=11) rated each indicator on six criteria using a 10-point scale. Ratings indicated overall high relevance, with acceptable content validity (S-CVI/Ave = 0.84). Event-based safety indicators and user acceptance were prioritized, while charging accessibility and operational efficiency showed greater disagreement, highlighting the need for clearer operational definitions and standardized measurement protocols. The proposed indicator set can complement existing certification schemes by enabling performance monitoring and supporting targeted design and operational improvements. Future work will validate the indicators and establish LOS grading thresholds through field measurements across building types.
