Because of its nature, i.e., the interior parts of a building, the energy engineer has less opportunity to aid in earning points in this program. This is the only program to date wherein the E & A credits are not the largest category. However, engineers in general do have the potential to aid points especially in the indoor environmental quality category.

Based upon the LEED NC rating system for new construction and major renovation, LEED CS was developed in recognition of the unique nature of core and shell developments. In particular, there is the lack of developer control over key aspects such as interior finishes, lighting, and HVAC distribution. Thus the scope of CS is limited to those elements of the project under the direct control of the developer.

With its standards for CS and CI, the USGBC addresses the entire building—core, shell, and interiors. The responsibilities for particular sections, however are assigned to those parties having direct control over them. LEED CS is still in its pilot phase as of early 2006. LEED CS Credit Categories

Below is a summary of where the points will be for LEED CS. Note its similarities to LEED NC and that energy & atmosphere is the largest points category.
