Above, we have described the so-called product-specific EPD –i.e. the declaration that describes how a specific building material impacts the environment.
However, if no EPD is available for the building material you want to use, you can either use a so-called industry average or sector EPD or rely on generic data from the ÖKOBAUDAT database.
Sector EPDs state an average for how building materials within a particular industry typically impact the environment. For example, you might have a sector EPD for concrete elements, windows, construction timber, tiles/brick etc. There is no sector EPD for cement-bonded wood wool products.
If possible, you should always choose product-specific EPDs, as these provide the most accurate data. For the same reason, you are required to add 10 per cent to the EPD values if you are using a sector EPD in connection with the certification of a building project. And if you use generic data, you need to add 30 per cent to the data.
