I don't see specified in the documentation the extent of measurements required in order to meet this credit.

It is correct that sound reinforcement systems are only required fro conference rooms or auditoriums for more then 50 people? Are masking systems optional in order to comply or mandatory?

Hi, This credit require to evaluate the sound isolation performance of constructions using STC rating which is very common in US. Our project is in Europe where STC rating is not use.

We just registered for this Credit - called EQpc24 - in the USGBC Pilot Credit Library for LEED 2009 . It was impossible logging into the forum from that webpage.

The documentation requires a composite STC of 50 between Office / Conference Room and Hallway / Stairway.

Is this ID credit approach asking for an effort substantially above and beyond the enhanced credit for LEED for Schools?

We are considering this credit for a New Construction Project. Before making a decision we need to estimate the engineering cost involved for this credit.

Is this s design or construction credit? From the credit form requirements looks like the NC levels will have to be measured, the rest criteria can be theoretically analysed or modeled.

Hi all, We have a clinic project that is seeking LEED HC certification and the credit IEQ c2 is similar to this pilot credit.
