Which category has no minimum point requirements?

The correct choice is indeed the category of Integrated Processes (ID). This category is designed to emphasize the importance of collaborative design processes and innovation in achieving sustainable outcomes. Unlike other categories that have specific point requirements tied to measurable performance outcomes — such as Energy and Atmosphere, Materials and Resources, and Indoor Environmental Quality — Integrated Processes allows for flexibility in how projects can demonstrate sustainability initiatives.

This flexibility is significant because it encourages teams to think creatively and enables a broader range of strategies to be employed without the pressure of scoring minimum points. The goal here is to support innovative approaches that may not fit standard metrics while still contributing positively to the project's overall sustainability objectives. This aspect reflects LEED's commitment to recognizing various pathways to achieve sustainability, thus prioritizing the integration of processes over strict quantifiable goals in this category.
