Rating SystemBasic Structure

General Changes 1. 110 Points Total (from 136)

2. Credit names are familiar

3. Order (numbering) is very differenta. Prereqs are pulled out front (p1, p2,

etc.)b. Credits follow (c1, c2, etc.)

4. Single Family, Low-Rise and Mid-Rise are Combined.

5. Bottom Line: Projects will lose one certification level.
