Connellsville Area Senior High School

253,000-SF renovation combined with 65,000-SF addition for facility serving grades 10-12 expanded its capacity to serve 9th graders and meet energy efficiency goals compliant with LEED gold standards. To meet design goals centered on energy efficiency and occupant comfort, an integrated design approach kicked off with meeting with teachers, administrators and architects. AD was part of these discussions and provided an acoustic study to assess performance of existing spaces. Recommendations identified opportunities for improving sound isolation for classrooms, meeting challenges associated with space reverberance in daylighting existing interior classrooms and finish strategies for both classrooms and open teaching areas for large group instruction. A comprehensive design review verified appropriate details for partitions and room finishes in concert hall with mechanical/electrical design details of new energy efficient systems. This assured that systems met background noise levels requirements for instructional purposes and compliance for LEED Gold standards.
