If a building is seeking credit for the efficiency of the DES under EA Credit, what should be included in the commissioning scope to earn Ongoing Commissioning?

Including all equipment, both upstream and downstream, in the commissioning scope is essential for earning Ongoing Commissioning for the efficiency of a District Energy System (DES) under the Energy and Atmosphere (EA) credit. This comprehensive approach ensures that the entire system is evaluated, optimized, and verified for performance.

By encompassing all components of the DES, it allows for a detailed understanding of how each piece of equipment interacts and contributes to the overall energy efficiency. Upstream equipment refers to the major systems supplying energy, while downstream equipment includes those that distribute energy throughout the building. Commissioning both types of equipment helps identify issues, ensures the systems operate as intended, and facilitates continuous performance monitoring.

The effectiveness of a DES relies on a holistic view of its components, as improvements in one area can significantly impact overall efficiency. Therefore, recognizing the interconnected nature of these systems and ensuring their optimal performance through ongoing commissioning is crucial for achieving energy efficiency credits in the LEED framework.
