hi, We are using LEED for Schools 2007 and am looking for some information on where to find STC ratings for ceiling and floor materials.

We have tectum panels (acoustic/insulation panels) above our beams. Do we have to add additional panels to the wall to make up for the ceiling area occupied by the exposed ceiling structure/beams?

The LEED v3 Reference book provides a table of "common materials". The LEED Online template asks for supporting documentation for all the materials used as an acoustic material finish.

The ANSI norm S12.60-2002 refers to IEC 61672-1 in order to define the A-weighted sound level. Is it allowed to use values from local code based on an acustic map of the city?

We are finishing up reporting on a school addition, and I have a few questions about the template. We are using the "calculation" option for both reverberation time and stc.

Has anybody grouped room types for Table IEQp3-1? I am trying to understand exactly how to do this. Simplified scenario: The project has 10 small 100 SF rooms, exactly the same.

In our classrooms and other core learning spaces, we are leaving a concrete, pan joist system exposed.
