Which credit is not eligible for Exemplary Performance?

The credit that is not eligible for Exemplary Performance is MR Design for Flexibility. This credit focuses on the incorporation of flexible design strategies that allow buildings to adapt to changing needs over time, primarily targeting material reuse and future adaptability rather than performance metrics. LEED rewards innovations and outstanding achievements in aspects directly related to environmental benefits, such as increased energy performance or enhanced indoor air quality.

In contrast, the other credits listed, including IAQ Enhanced Air Quality Strategies, IAQ Low-Emitting Materials, and IAQ Indoor Air Quality Assessment, are all eligible for Exemplary Performance because they involve quantifiable enhancements leading to improved indoor environmental quality. These credits offer opportunities for teams to achieve higher levels of performance than the standard requirements, thereby addressing issues like pollutant levels and overall occupant comfort more effectively, which can be measured and verified.

Therefore, MR Design for Flexibility stands out as it does not directly offer a pathway for such measurable performance enhancement in the same way that indoor air quality strategies do, which is crucial for achieving Exemplary Performance in LEED certification.
