Requirements
- Conduct a site noise assessment. Perform qualitative assessments of nearby noise sources and noise-sensitive receivers, and/or a quantitative measurement of site noise in at least one location for at least 24-hours.
-
Design and locate exterior noise sources1 so that the following project noise levels are not exceeded at the project boundary:
- For boundaries adjacent to residential buildings:
-
For boundaries not adjacent to residential buildings:
- Outdoor Day-Night Equivalent Level (Ldn) or Community Noise Equivalent Level (CNEL) of 60 dBA
- Additionally, for residential projects, do not exceed the following noise levels in bedrooms:
General Pilot Documentation Requirements
Register for the pilot credit- Participate in the LEEDuser pilot credit forum
- Complete the feedback survey:
Submittals/Documentation
- Narrative describing the site noise assessment conducted. Describe the boundary types (whether boundaries are adjacent to residential buildings) and for boundaries adjacent to residential buildings, include the existing ambient levels and explain how this level was determined.
- Calculations or measurements for noise levels, including description of noise sources included in the analysis.
- Operations plan for testing of emergency equipment, describing the reason a particular time of day was chosen for testing.
Changes
- Changes made 6/4/2015: The credit intent has been revised to better reflect the purpose of the credit. The exterior noise criteria have been revised to align with existing community noise guidelines The requirements have been revised to separately address noise concerns for residential buildings, including a new requirement for noise levels in bedrooms.
What does it cost?
Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
