Red List

Red List Free Materials for Green Building

Introduction to Red List Free Materials

  • Concept of Red List Free Materials:

    • Designing homes that are healthier for individuals and better for the environment.

    • A core idea is to select materials that do not contain harmful chemicals, thus improving the overall health of occupants.

Importance of Red List Free Materials

  • Red List materials help meet standards like the Living Building Challenge:

    • Emphasizes buildings that contribute positively to their surroundings.

  • Established by the International Living Future Institute (ILFI).

    • Purpose: Identify chemicals in building products harmful to human health and the environment.

Chemicals Identified on the Red List

  • Includes substances known to be hazardous:

    • Formaldehyde:

      • Found in pressed wood products.

    • Phthalates:

      • Commonly used in plastics.

    • Heavy Metals:

      • Includes mercury and cadmium.

  • Definition of Red List Free:

    • A material classified as red list free means it does not contain any red list chemicals.

Examples of Red List Free Materials

  • Natural and minimally processed options:

    • Untreated Wood:

      • Sourced sustainably.

    • Clay Plasters:

      • Used for wall finishes.

    • Linoleum:

      • Often free from harmful chemicals.

  • Benefits of Using Red List Free Materials:

    • Improvement in indoor air quality.

    • Reduction of health risks for inhabitants.

Building Standards and Compliance

  • Living Building Challenge Requirements:

    • 90% of building materials (by cost) must be Red List free.

    • Exceptions allowed for small components or complex products documented thoroughly.

  • Manufacturer Transparency:

    • Importance of detailed ingredient disclosures.

    • Programs like the Declare label aid this transparency by listing all product ingredients.

Market Growth and Research Necessity

  • Increasing availability of Red List Free materials but research may be required:

    • Builders are encouraged to inquire about ingredient lists.

    • Search for third-party certifications.

  • Temporary exceptions may exist but the underlying goal remains the same: trending towards safer options.

Health and Environmental Implications

  • Supporting healthier indoor environments through material choices aligns with sustainable building practices:

    • Promotes energy-efficient construction.

    • Aims for regenerative building outcomes.

  • Urgency and necessity of restorative action:

    • Current environmental crisis necessitates the choice of safer materials in construction projects.

Chemical Exposure and Safety Regulations

  • Overview of chemical use in products:

    • Chemicals are ubiquitous in daily life, e.g., fabrics, furniture, food packaging.

    • Approximately 86,000 chemicals reported by the EPA under the TSCA inventory.

    • As of 2023, over 42,000 of these are active but many lack adequate risk evaluation.

Living Building Challenge Red List

  • Definition of the Red List:

    • A comprehensive list citing serious health risks and environmental hazards.

    • Contains over 800 chemicals known to be toxic.

    • Mandates that 90% of material costs must not involve Red List chemicals for certification.

  • Common Red List Chemicals:

    • Asbestos:

      • Historically used for insulation; known carcinogen.

    • Lead:

      • Found in paints and pipes, responsible for various health issues.

    • Vinyl Plastic (PVC):

      • Associated with health concerns and environmental persistence.

  • ILFI's Management of the Red List and Declare Program:

    • The Declare label enhances product transparency to help builders select safer materials.

Resources for Builders and Designers

  • Using Declare labels as a straightforward resource:

    • Products can be Declared as Red List Free or with temporary exceptions.

    • Comprehensive checks are required for Red List compliance, promoting sustainable material use (recycled, salvaged, responsibly sourced).

  • Certification Recognition:

    • Sustainable programs like LEED (Leadership in Energy and Environmental Design) also recognize Declare labels.

Future Directions and Recommendations

  • Need for consumer awareness and engagement with sustainable materials:

    • Ask manufacturers for ingredient transparency.

    • Think critically about materials used in both personal and professional settings.

  • Urgent action is required to transition to a regenerative society:

    • Encourage manufacturers to innovate and adopt safer materials.

    • Collective responsibility to support businesses that prioritize health and the environment.
