The Chemical Abstract Service is associated with which MR credit?

The Chemical Abstract Service (CAS) is closely associated with the Material Ingredients credit within the LEED BD+C V4 framework. This credit is designed to encourage project teams to disclose and optimize the chemical ingredients used in building materials, promoting transparency regarding the health impacts of those chemicals. The CAS registry assigns unique identifiers to chemical substances, which helps in identifying, tracking, and communicating the chemical makeup of materials effectively. By using CAS numbers, project teams can better assess the potential health and environmental impacts of the materials they are incorporating into their designs.

In contrast, Raw Materials Sourcing focuses on the sustainability of the materials used, such as their extraction and transportation methods, rather than the specific chemical content. Design Innovation pertains to innovative strategies that go beyond the standard LEED requirements and does not directly relate to the identification or management of chemical substances in materials. Energy Efficiency is a separate category that deals primarily with the performance of a building in conserving energy, which is unrelated to the material composition.
