Specification of green acoustical materials is difficult to implement from the acoustical expert’s perspective. A contributing factor is the accepted definition of “green” that is poorly understood by the acoustical community. The widely accepted interpretation of the term does not refer exclusively to building materials that have a high recycled material content or are made without the use of toxic chemicals but extends to the entire project. Overall building design implications extend beyond material content to water consumption, energy use, and to the health and wellness of the occupants. These larger considerations are reflected in the most prevalent green rating system, the LEED rating system as established by the United States Green Building Council (USGBC). Within the framework of a larger, holistic building system, acoustical material can be considered green on three levels: (a) its contribution to the health and comfort of the building occupants, (b) environmentally preferable nature of its components or manufacturing process, and (c) its secondary performance features that have a positive impact on other building systems. Acoustical experts must therefore review the “green‐ness” of sound control materials in this same framework. A review of such an approach and a review of existing green acoustical products will be presented.
