What is commissioning and why is it important for LEED?

• A. The process of selecting materials based on color and texture.
• B. A post-occupancy survey to evaluate occupant comfort after turnover.
• C. A dedicated process to verify and document that building systems perform according to their design intent.
• D. A budgeting exercise to estimate project costs.

Answer: (C)

Commissioning is a structured process to verify and document that building systems perform according to their design intent, from planning and design through construction and occupancy. It includes establishing the owner’s project requirements, conducting functional performance tests, calibrating controls, and compiling verification documentation to prove systems operate as intended. In LEED, fundamental commissioning and verification is a prerequisite for new construction and major renovations, ensuring energy-related systems are designed, installed, and calibrated to run efficiently. This proactive verification helps achieve better energy performance and indoor environmental quality, and Enhanced Commissioning can earn additional points by expanding the scope and depth of verification. This process is distinct from selecting materials, post-occupancy surveys, or budgeting activities.
