The Three Types of EPDs

The Three Types of EPDs

This post is a follow up to our earlier post on Environmental Product Declarations.

Three types of Environmental Product Declarations can contribute towards Option 1 of the Environmental Product Declarations credit. A product with any of the following three documents below will help a project team achieve the 20+ product threshold needed for credit achievement.

  • Product-Specific Declaration
  • Industry-Wide (Generic) EPD
  • Product-Specific Type III EPD

These three types of EPDs are meant to accommodate the various stages of EPD development throughout the different industries. Based on the stage of development, each type of EPD is valued as a quarter of a product, half of a product or one whole product in terms of how much each document contributes towards LEED compliance. All EPDs must be publicly available, however the materials an EPD does or does not reference will help determine what kind of EPD it is.

Once the project has reached the 20+ product threshold using any of the three documents above, Option 1 of the Environmental Product Declaration credit is complete. Option 2 requires products to show an impact reduction below industry average for 50% by cost. In order to achieve this option, a product must have two EPDs – the industry-wide (generic) EPD and a Type III EPD. Both documents are needed to compare the generic to the Type III EPD and demonstrate that the Type III is showing a reduction below industry average. Currently, not many industries have a generic EPD, which makes Option 2 difficult to achieve.
