06. Indoor Environment - Exterior Acoustic Comfort

Implement acoustic control measures to minimize exterior-sourced noises

Rationale: Acoustic control measures like using soundproofing materials or leveraging dense foliage and greenery to minimize exterior-sourced noises, such as road traffic noise, supports improved sleep and cognitive functioning — contributing to reduced rates of stress, depression, and cardiovascular diseases such as hypertension and coronary heart disease.

For the most accurate strategy and documentation requirements, please refer to the digital scorecard made available on the Fitwel Platform.

Requirements

Demonstrate compliance with one of the options below:

Option 1 - Acoustic Control Measures (Full Credit):

To achieve full credit, demonstrate compliance with all of the following requirements:

Multi-Tenant Whole Building (no on-site management), Multi-Tenant Whole Building (with on-site management)

1. Limit exterior-sourced noises caused by highways, heavy traffic, busy streets, busy gathering spaces, or other external factors by implementing a minimum of two of the following qualifying acoustic control measures throughout the building(s):

• orienting all workspaces away from the noise sources
• sealing all exterior windows and doors
• using soundproofing materials on all external walls
• placing areas of dense foliage between noise sources and work areas.

Multi-Tenant Base Building

1. Limit exterior-sourced noises caused by highways, heavy traffic, busy streets, busy gathering spaces, or other external factors by implementing a minimum of two of the following qualifying acoustic control measures throughout the building(s):

• orienting all workspaces away from the noise sources
• sealing all exterior windows and doors
• using soundproofing materials on all external walls
• placing areas of dense foliage between noise sources and work areas.

Single-Tenant

1. Limit exterior-sourced noises caused by highways, heavy traffic, busy streets, busy gathering spaces, or other external factors by implementing a minimum of two of the following qualifying acoustic control measures throughout the building(s):

• orienting all workspaces away from the noise sources
• sealing all exterior windows and doors
• using soundproofing materials on all external walls
• placing areas of dense foliage between noise sources and work areas.

Option 2 - STC Rating (Full Credit):

To achieve full credit, demonstrate compliance with all of the following requirements:

Multi-Tenant Whole Building (no on-site management), Multi-Tenant Whole Building (with on-site management)

1. Provide exterior walls for the building(s) with a Sound Transmission Class (STC) rating of at least 60.

Multi-Tenant Base Building

1. Provide exterior walls for the building(s) with a Sound Transmission Class (STC) rating of at least 60.

Single-Tenant

1. Provide exterior walls for the building(s) with a Sound Transmission Class (STC) rating of at least 60.
