I heard that Arc is free. Is that true?
Yes! Access to Arc is free and includes everything a project team needs to get started measuring and managing performance. For details, see the "Arc for all" article.
If your team wishes to submit project data for review to pursue an initial LEED O+M certification or LEED O+M recertification using Arc, then regular LEED fees will apply. For details, see the USGBC fees page. For recertification, the registration fee is waived.
