What acoustic façade simulation reports are typically requested when evaluating curtain wall noise-control capability?

Acoustic façades require both laboratory metrics and site-specific simulation outputs. Deliverables should include: (a) Laboratory airborne sound insulation (Rw) or STC values for the curtain wall and window units per ISO 10140 / ASTM E90; (b) Octave-band transmission loss data to support façade noise modeling; (c) Façade noise reduction simulations using site-specific noise sources (traffic, rail, industrial) with software inputs and results (e.g., SoundPLAN, CadnaA), showing expected indoor levels and compliance with local noise criteria; (d) Reverberation/time delay considerations when façades include reflective elements; (e) Modelling of flanking paths (ventilation slots, service penetrations) and their effect on overall insertion loss; (f) Recommendations for glazing/ventilation selection, acoustic seals, and cavity treatments to meet target indoor dB(A) levels; (g) On-site measurement protocols for post-installation verification and acceptance criteria; (h) Third-party acoustic consultant sign-off where necessary and metadata for BIM objects containing frequency-dependent transmission loss values. Provide raw simulation files and assumptions so acoustic consultants can reproduce outcomes against project noise scenarios.
