Flooring and Carpet

Design Considerations:

Natural or Recycled -  Select flooring products that contain recycled content and may be recycled themselves.  All attempts should be made to select flooring products that have minimum emissions to prevent an accumulation of chemicals in the indoor environment.  Consider reusing textiles from a previous location.

Raw Materials Acquisition - Recycling of materials is desirable and provisions should be made when possible for the reuse of all products by the manufacturer.    

Raw Materials Processing and Manufacturing -  Avoid using flooring products that require high amount of embodied energy to build and create a potential environmental desecration through the chemical production.  Criteria for materials should be set to conserve resources.  Questions such as: Is it needed?  Is there a substitute with lower mass and/or lower embodied energy?

Product Distribution -  Use flooring products that have been manufactured in an "sustaining" manner. Consider the environmental impacts of flooring transportation in your purchasing decision.  Product that can be shipped in large bulk or that do not need to be transported over long distances reduce the embodied energy used; products produced locally in a region help support local economies; products should be selected that  are climatically appropriate solutions for that region; consider the impact of product selection on the user's sense of culture and community.

No / Low Emissions-   Look for products that do not pollute the air inside the building.  Toxicity of emissions from materials should be carefully reviewed to protect indoor air quality, paying particular attention to exposure limits and known medical hazards. For textured floor materials look for carpet that has the Carpet and Rug Institute (CRI) "green label": 

Emissions from carpet meeting the "green label" specifications will not exceed:

  • 0.5 mg/m2 hr TVOC (total volatile organic compounds)
  • 0.4 mg/m2 hr Styrene
  • 0.1 mg/m2 hr 4-phenylcyclohexene (4-PC)
  • 0.05 mg/m2 nr HCHO (formaldehyde)

Emissions from flooring adhesives that meet the CRI "green label" will not exceed:

  • 10.0 mg/m2 hr TVOC
  • 3.0 mg/m2 hr 2-ethly-1-hexanol
  • 0.05 mg/m2 HCHO

Disposal & Renewability- Attempts should be made to use recyclable or biodegradable materials.
