LEED Requirements

LEED 2009 For Schools – Indoor Air Quality Credit 9, requires classrooms and other core learning spaces meet STC requirements for the ANSI Standard S12.60-2002. Several STC ratings for interior doors are referenced within the standard, depending on the location of the learning space. STC 30 is the minimum requirement for all classroom doors, and music room doors require a minimum STC rating requirement of STC 40.
