HVAC Background Noise - sound rating methods

NC-v4.1 EQc9:Acoustic Performance
posted by  Iris Meeker  on 

For the HVAC Background Noise, do all spaces have to use the same Sound Rating Method (NC/RC, dBA, dBC, RC(N)), or can these vary by individual space or by space type?

We have an office project that looks at achieving both Leed and Well guidance for acoustics. Does anyone have similar experience? And if so which was the overriding criteria?

I filled out these Excel Workbook forms several months ago and now I cannot get access because it asks for a Password that I do not have. How can this be bypassed or a Password provided?

Is this credit to require all of the structure (walls, floor, floor slab, roof ect.) to be accounted for in measuring for this credit? Or just the walls?
