Implement radon control measures

Rationale: Radon is a carcinogen found in soil and rock that can seep into lower levels of buildings through cracks in the foundation; testing, monitoring and controlling radon gas effectively limits occupant exposure reducing lung cancer risk.

Requirements

Demonstrate compliance with one of the options below:

Option 1 - Radon Testing or Monitoring - (Full Credit):

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

Multi-Tenant Retail, Retail

1. Test or monitor for radon according to the following sections in the Fitwel Radon Testing or Monitoring Requirements:

• • • frequency
    • qualifying devices
    • required locations
    • methods
    • metrics. 

The Fitwel Radon Testing or Monitoring Requirements can be found here.

Option 2 - No Applicable Testing Locations - (Full Credit):

The project may achieve partial credit by demonstrating compliance with all of the following requirements:

Multi-Tenant Retail, Retail

1. Confirm that the project does not include any of the following spaces:
   – interior spaces located at or below grade
   – interior spaces with floors or walls that contact the ground

Option 3 - Radon Control Measures - (Partial Credit):

The project may achieve partial credit by demonstrating compliance with all of the following requirements:

Multi-Tenant Retail, Retail

1. For projects where the recommended limits for radon levels are not met, establish and implement a radon mitigation and remediation plan that includes a minimum of one of the following interventions:

• • • active soil depressurization or soil suction
    • home or room pressurization, which uses a fan to blow air into the spaces with elevated radon levels
    • installation of a heat recovery ventilator or an air-to-air heat exchanger
    • natural ventilation of spaces with elevated radon levels
    • sealing openings in surfaces between the indoors and the soil.
