LEED Fundamental Commissioning
A commissioning process required for LEED certification that is conducted to confirm that building energy systems perform according to the Owner’s Project Requirements (OPR) and the Basis of Design (BOD). A commissioning agent develops procedures to monitor progress throughout the construction process, reports concerns and summarizes results in a final commissioning report.
LEED Enhanced Commissioning
A more advanced LEED commissioning process which includes requirements beyond those included in Fundamental Commissioning. Enhanced Commissioning requires a commissioning agent to review documents during the design phase to confirm that they are consistent with the Owner’s Project Requirements (OPR) and the Basis of Design (BOD). In addition, the process also includes a training audit to ensure the building’s operating staff understands equipment operating and maintenance requirements. A commissioning agent will also perform a review of building operation prior to conclusion of the warranty period so that operational issues are identified and a plan is in place to resolve deficiencies prior to warranty expiration.
A non-LEED, standard commissioning process begins during the design phase and continues through construction and occupancy of the facility. This process involves documentation, adjustment, testing, verification and training that is performed specifically to ensure that the finished facility operates in accordance with the owner’s project requirements and the construction documents. It involves many of the same requirements of fundamental and enhanced LEED commissioning, but does not require the same level of detailed documentation and reporting.
An alternative to LEED or standard commissioning that is intended to verify that the systems are installed and operating in accordance with the owner’s project requirements by focusing on field adjustments, functional performance testing and verification during the construction phase that is limited to a representative sampling of equipment. System validation is a lower cost alternative that delivers similar benefits as Standard Commissioning without the extensive documentation.
