This Application Guide is designed to complement the LEED Green Building Rating System and the LEED Reference Guide. The Application Guide should be used as a working document that is referenced and updated frequently throughout the design process. In this manner, the Application Guide serves as a checklist of suggested steps and can be used to track the progress of the design team in the completion of those steps. Because changes in the building design affect the anticipated LEED score, these changes should be tracked as they occur. The elements of this Application Guide include a LEED Scorecard, the Prerequisite and Credit Descriptions and an Appendix.
