The ?rst section of the guide describes the six design requirements for projects to receive incentives from the Program and explains why these particular metrics were chosen ? The second section of the guide provides an overview of lighting terminology ?? it will help you understand the language of lighting ? Next in the third section is a discussion of the important elements of lighting design that constitute good lighting ? The ?nal section provides you with a practical path toward developing and implementing e ?ective energy-e ?cient lighting designs This guide and other tools and resources related to lighting are available for on- line viewing or download at the SCLP web site http www nyserda org sclp Copies of all Program materials may be obtained upon request from your SCLP Account Manager You may also direct any questions or requests for information that are not included in this guide to
