Environmental Product Declaration: MR0003

Format On Demand: Online
Offered by USG Corporation
Category Materials and resources

This USG course reviews what is an Environmental Product Declaration (EPD) and what goes into them. This course review what is published in EPDs and how they are the score card of a Life Cycle Assessment of a product, system or service based on Product Category Rules (PCR) for that product family. This course reviews environmental impacts as outlined in ISO 14040 and how a PCR may or may not include all these Impacts. This course also discusses limitations using examples of LCA and how simple number comparisons can be misleading. Discuss covers additional attributes like durability, adaptability, and performance; after all the Greenest building is theone that does not have to be re-built. Proper specification and detailing of systems will improve the overall performance of your design solutions. We all know durability of a material can affect the building's performance more than any other material attribute, for example we would not use an un-coated steel exterior panel in a high-salt environment. Or a bamboo floor in a high-traffic publiclobby. Durability is one of the biggest impacts on a product's Life Cycle Assessment (LCA) but how is it determined?

Product decisions are made everyday based on all kinds of attributes and trade-off. Understanding the (LCA) of the product you choose for you product will broaden your knowledge allowing you to make intelligent decision selections for your next project. Environmental ProductDeclarations (EPD) are surfacing, what are they and how do they differ from a product LCA?

Learn the basics behind product LCAs,Embodied Energy, and EPDs to assist with future product selections and evaluations. This program discusses what is involved with LCAsand EPDs using examples and some basic rules of thumbs that will aid you in the understanding what you will need to wade throughtheclaims. Embodied energy of product is an important metric when comparing material chooses, but can it be misleading and should all materials be recycled?


1. Review a building LCA and percentage of Initial and recurring energies
2. Review simple product Embodied Energy and compare with other materials
3. Discuss material comparisons of Embodied Energy and LCAs
4. Review why some materials should be recycled but others materials may use other options to achieve land fill avoidance based on their Embodied Energy
5. Discuss the difference of a product LCA and an EPD
