EPD for US Plywood, OSB, I-Joists and LVL

The American Wood Council has produced four EPD relating to softwood_Plywood_EPD, OSB_EPD, I_Joists_EPD and LVL_EPD.

The British Research Establishment and the US Underwriters Laboratories  now recognize each other’s certified EPD making it simpler for APA member mills to gain environmental performance ratings under the BRE Environmental Assessment Method  (BREEM).  This is the UK’s leading and most widely used environmental assessment method for buildings and communities. It sets the standard for best practice in sustainable design and has become the de facto measure used to describe a building’s environmental performance.

Each EPD provides a standardised Transparency Brief which summarises the most important information including:

  • composition
  • material content
  • water and energy usage

The Transparency Brief also covers the following life cycle environmental impact categories:

  • Global warming potential
  • Ozone depletion potential
  • Photochemical and ozone creation potential
  • Acidification potential
  • Eutrophication potential
  • Depletion of abiotic resource (elements and fossil fuels)
