CEN/TC 350

The changes in the building sector towards more sustainability lead to new information requirements for buildings and therefore building products. Since sustainability is assessed on a building level, not on a product level, relevant product related data is required in a harmonised format for building assessments. This product related data needs to be life-cycle based and covers various environmental impacts (including energy issues) from the cradle to the grave (from raw materials to after-production-stage).

To find a common European approach and to eliminate barriers to trade, CEN has developed standards for the sustainability assessment of buildings (EN 15978), as well as for relevant product information (EN 15804) which was released in January 2012.This standard has an amendment published in 2013.

EN 15804 “Sustainability of construction works — Environmental product declarations — Core rules for the product category of construction products” provides core product category rules (PCR) for Type III environmental declarations for any construction product and construction service.

This standard:

  • defines the parameters to be declared and the way in which they are collated and reported
  • describes which stages of a product’s life cycle are considered in the EPD and which processes are to be included in the life cycle stages
  • defines rules for the development of scenarios, includes the rules for calculating the Life Cycle Inventory and the Life Cycle Impact Assessment underlying the EPD, including the specification of the data quality to be applied
  • includes the rules for reporting predetermined, environmental information, that is not covered by LCA for a product, construction process and construction service where necessary
