The blank provides guidance for deciding which rating system to pursue when several rating systems appear to be appropriate for a project. The blank is as follows:
*If a rating system is appropriate for less than 40% of the gross floor area of a LEED project building or space, then that rating system should not be used.
*If a rating system is appropriate for more than 60% of the gross floor area of a LEED project building or space, then that rating system should be used.
*If an appropriate rating system falls between 40% and 60% of the gross floor area, project teams must independently assess their situation and decide which rating system is most applicable.
