Which prerequisite applies specifically to all projects regarding refrigerants?

The prerequisite that applies specifically to all projects regarding refrigerants is Fundamental Refrigerant Management. This prerequisite is designed to ensure that projects minimize the impact of refrigerants on the environment, particularly concerning ozone depletion and global warming potential. It requires project teams to evaluate their refrigerant use and make informed decisions centered on environmentally friendly refrigerant options.

This focus on refrigerant management is crucial because HVAC systems often use refrigerants that can have a significant environmental impact if not managed properly. Therefore, Fundamental Refrigerant Management aims to promote sustainability and reduce harmful emissions across all projects, aligning with LEED's overarching goals of improving environmental performance in the built environment.

In contrast, the other options pertain to different aspects of building design and performance. Building-Level Energy Metering focuses on monitoring energy usage, while Minimum Energy Performance sets baseline energy efficiency requirements. Advanced Energy Design Guidelines provide guidance for high-performance building design, but none of these specifically address the management of refrigerants across all projects.
