At Institut Bauen und Umwelt e.V., two different EPDs are generally offered: the IBU EPD and the “Core EPD”, in accordance with EN 15804. The primary difference between these two types of EPD is the extent of information provided. The Core EPD contains only normative mandatory required contents. Specifically, this means that a Core EPD, among other things, contains no data regarding the production, product processing, conditions of use, disposal, or the behaviour of the product in unusual circumstances. Further, neither Chapter 6 (Life Cycle Assessment Interpretation) nor Chapter 7 (Evidence) are included. These missing chapters significantly reduce the usefulness of the EPD in comparison to a complete IBU EPD, which is why, in order to supply information that is as concise and comprehensive as possible, the IBU normally recommends the creation of an IBU EPD.
