LEED-CS stands for Core and Shell. Which option best represents the abbreviation?

• A. LEED Core and Shell
• B. LEED Core and Systems
• C. LEED Construction and Shell
• D. LEED Commercial and Shell

Answer: (A)

The term CS in LEED-CS stands for Core and Shell. In LEED terminology, Core and Shell refers to projects where the base building’s core components (like cores, stairs, elevators, and shared mechanical/electrical/plumbing elements) and the exterior shell (structure and envelope) are completed, while the tenant’s interior fit-out is not part of the project scope. That makes “LEED Core and Shell” the correct expansion.

Other options misstate the meaning: “Core and Systems” would imply including tenant systems, which isn’t the standard interpretation for this rating, and the others use terms not used in the official name of the rating system.
