What document provides guidance for materials and resources in LEED certification?

The LEED Reference Guide is the key document that provides comprehensive guidance on materials and resources within the context of LEED certification. It serves as an essential resource for project teams, offering detailed insights into the specific credit requirements and strategies for achieving points related to materials and resources. This guide helps practitioners understand the nuances of material selection, recycling practices, and the importance of sustainable products in the construction process.

While the LEED Handbook and the LEED Certification Manual contain useful information about the certification process and overall strategies, they do not focus specifically on the materials and resources aspects to the same extent as the Reference Guide. The LEED Scorecard, on the other hand, is primarily a tool to track credits and points achieved, rather than a source of detailed guidance on how to meet the requirements. Thus, the LEED Reference Guide is recognized as the authoritative document for understanding and implementing materials and resources criteria in a LEED project.
