KEY
Measures that are met based on GSA standards or mandates (no premium)
Measures with no cost premiums, or with potential cost decreases
Measures with low cost premiums (<50K for Models from GSA LEED Cost Study)
Measures with moderate cost premiums (between 50K - 150K for Models from GSA LEED Cost Study)
Measures with high cost premiums (>150K for Models from GSA LEED Cost Study)
Measures with variable cost premiums, depending on project conditons
Measures not applicable to the project
Measures unlikely to be pursued on typical GSA projects
Measures not pursued, although technically viable
