Which credit is specifically noted as not being eligible for Exemplary Performance?

The credit that is specifically noted as not being eligible for Exemplary Performance is indeed all of the options listed. In LEED V4, certain credits are structured in a way that they do not offer opportunities for additional points through Exemplary Performance measures.

The Optimize Energy Performance credit, for instance, is already aimed at maximizing energy efficiency within the project, so its metrics are tightly defined and maximizing points through additional performance is not applicable.

Similarly, the Demand Response credit focuses on the capacity to reduce energy use during peak demand periods, and the enhanced commissioning process ensures that building systems are designed, installed, and operate as intended. All of these credits have specific performance metrics that do not allow for the flexibility or additional advancements that Exemplary Performance typically entails.

Therefore, since none of the individual credits can achieve Exemplary Performance, selecting that all of the above credits are not eligible is correct. This provision is part of maintaining consistent evaluation standards within the LEED certification process, ensuring that different types of credits have distinct performance pathways.
