Consideration of acoustics in leadership in energy and environmental design (LEED) version 4

Acoustical criteria have been added to the LEED rating systems with each new revision, beginning with Schools and Healthcare. With the recent Version 4 update, an acoustical credit has been added for the majority of New Construction LEED rating systems. There are weaknesses in the acoustical LEED credits, including imbalance between cost and benefit, mitigation beyond industry standards, and implementation of requirements within non-sensitive areas. This paper reviews the purpose of acoustics within a sustainable design system, identifies areas where the current language hits the mark or should be revised, and adds areas for future consideration of acoustical design within a sustainable design rating system.
