Internally generated noise

Intent:

To reduce acoustic disruptions from internal noise sources and increase speech privacy.

Post Date: 09 Feb, 2017 Status: Approved Whereas Noise Criteria levels within a space is driven by sound produced by the HVAC and other mechanical systems which may be outside of a tenant’s control, New and Existing Interiors projects may achieve Feature 75 when achieving NC levels higher than listed, with the following conditions: - Achieve NC levels of 5 higher, but the project is limited to Gold level of certification, no matter how many Optimization features are achieved. - Achieve NC levels 10 higher, but the project is limited to Silver level of certification, no matter how many Optimization features are achieved.
Post Date: 06 May, 2016 Status: Approved Noise Rating curve values may be used in lieu of Noise Criterion curve values for the mechanical equipment sound levels required in Part 2 of this feature using the same maximum criteria values listed for each space type. The project team must indicate in their documentation application if Noise Rating is to be used in lieu of Noise Criterion.
