The common challenge with any mass timber core and shell project is finding the right balance between sustainability and the need for acoustic separation. How do we isolate the mechanical floor from the office floors? How do mass timber materials interact with the façade? What is the best way to minimize footfall noise from transferring between floors? And how do we enhance the acoustical performance of each floor without sacrificing the aesthetic design of the exposed wood and concrete? The acoustical team from Cerami, part of Trinity Consultants, worked closely with the client and the design team to develop strategies to address these uncertainties.
