Which category in LEED evaluates the performance of energy systems after construction?

The category in LEED that evaluates the performance of energy systems after construction is commissioning. This process involves the verification of the performance of all building systems, including HVAC, lighting, plumbing, and electrical systems, to ensure they are installed and functioning according to the design intent and operational requirements.

Commissioning is essential because it helps identify and rectify any issues before the building is occupied, ensuring that energy systems perform efficiently and effectively. The goal is to optimize the system performance, enhance energy efficiency, and contribute to the overall sustainability of the building.

Effective commissioning can lead to significant energy savings, improved occupant comfort, and extended equipment life, illustrating its vital role in energy management within the LEED framework. This ongoing evaluation ensures that the systems not only meet targets initially set during design but continue to perform well throughout their operational lifespan.
