The project as described meets the intent of the acoustics prerequisite, and is therefore in compliance. Specific responses to items 1 through 4 are as follows: 1. Acoustical performance estimates for the composite wall assembly and exterior noise levels confirm that background noise levels will be below 40 dBA. The exterior wall/window assembly is therefore in compliance with the prerequisite. 2. As a flexible, supervisory space with no lecture type of instruction, the space is exempt from the STC requirements. 3. The composite performance of the exterior wall and door supports interior noise levels below 40 dBA and is therefore in compliance with the prerequisite. 4. The Library and additional rooms as described in the CIR are not core instructional spaces, and are therefore exempt from the STC requirements. Applicable Internationally; UAE.
