What a formal rating involves

Dozens of indicators across eight dimensions (our detailed scoring rules remain internal, to avoid being copied).

Four sources of evidence: site survey · on-site measurement · document checks · occupant interviews.

Two reviewers score independently; results can be appealed and corrected.

Regular reviews — no stone is permanent: typically every 2 years (every 3 years for company-owned offices); a major change triggers an interim review.

Ratings and recommendations on this site are reference conclusions drawn from public information and our own data; they do not constitute any official certification or qualification. We are equally candid about this limit: if you find an inaccuracy, please tell us via this site, and it will be corrected once verified. © 2026 Shanghai Ouyan Network Technology Co., Ltd.
