A short feedback about our experience concerning EQ PC 57 use, for an office tower project in France (Marseille) under LEED CS V3.
For this project, LEED CS V3 and French "HQE" (High Environmental Quality) certification is also targeted. Within "HQE" certification, acoustics issues are studied in the target number 9 “acoustic comfort”. Therefore, these studies were already made when we decided to target this EQ PC 57 credit.
This EQ PC 57 could be enhanced by taking into account local regulations as BREEAM or HQE systems do. Indeed, the LEED objective in terms of “Ldn” does not match with the French acoustic approach (exterior noise emergence issue).
I hope that helps.
