Hi, I have project where is several open plan offices with different volumes. LEED Acoustic Performance requires T60 below 0.8 sec.

The LEED v4 acoustics credit addresses sound isolation purely through composite STC ratings. In my research, I have struggled to find STC ratings for ceiling products.

Dear all, I have a question according to meet the composite sound transmission class (STCC) ratings listed in Table 1: Do we have to meet the STC rating for the combination 'office - hallway' for a

For a project, we are dealing with the following situtation: we have small meeting rooms, situated (as "boxes") in an open-office plan.

The LEED v4 acoustics calculator expands on the guidance provided in the credit and reference guide with respect to the sound transmission requirements and associated calculations.

Hi, we have a project with large waiting rooms: are there specific values for "Reverberation time requirements", as there are not similar room type in the table 2 of reference guide? Thanks

Sound transmission requirements for adjacency combinations are listed in Reference Manual Table 1.

I know under LEED that the design engineers cannot also be the Cxa, but does that also apply for an entity/company who is the building envelope CxA but can also be the acoustical engineers?

Hello, Is it possible to pursue this credit in a Core&Shell certification in the Innovation section ?
