  1. Reducing Carbon Footprint: Absorbs and stores carbon dioxide, reducing greenhouse gases.
  2. Energy Efficiency: Requires less energy to produce and process than steel or concrete.
  3. Renewability: Can be sustainably harvested and replanted.
  4. Biodegradability: Breaks down naturally at the end of its life cycle.
  5. Enhancing Indoor Air Quality: Naturally regulates humidity and emits fewer pollutants than synthetic materials.

How is wood being used in green building certifications like LEED?

Wood is used in green building certifications like LEED (Leadership in Energy and Environmental Design) by:

  1. Sourcing: Using certified sustainable wood products (e.g., FSC-certified) to earn points.
  2. Energy Efficiency: Contributing to energy efficiency through its natural insulating properties.
  3. Indoor Environmental Quality: Improving indoor air quality with low-emission wood products.
  4. Material and Resources: Utilizing reclaimed or rapidly renewable wood products.
  5. Innovation: Incorporating advanced wood technologies and designs to achieve higher LEED ratings.
