EPD – Environmental Product Declaration

  • EPDs form the data basis for an environmental building assessment in accordance with DIN EN 15978: Sustainability of construction works – Assessment of environmental performance of buildings – Calculation method.
  • EPDs are based on international standards (ISO 14025; ISO 14040ff) – as well as the European DIN EN 15804, and are therefore internationally coordinated. They are suitable as proof of environmental requirements in public procurement processes.
  • EPDs provide a relevant data basis to show the environmental characteristics of a product in marketing or sales.
  • Through the comprehensive life cycle assessment developed in the creation of EPDs, manufacturers have the opportunity to recognise and optimise hotspots in their production process.

Most building products are utilised in combination within a single ‘system’ – the building. A Type III declaration for building products, which at the same time also aids in evaluating the entire building, has obvious advantages. Resource consumption and emissions into the environment are, at a minimum, recorded over the entire manufacturing process (from cradle to factory gate). The resulting contributions to the greenhouse effect, over-fertilisation, or the acidification of bodies of water can be quantified and evaluated with the life cycle assessment methodology. Life cycle assessments thus provide a systematic and standardised data basis for the ecological evaluation of a building in a ‘building block system’, based on declarations from individual building products. A life cycle analysis takes into consideration the entire life span of the building, from the building phase, to the utilisation phase with possible alternative uses, as far as demolition and disposal, and can indicate the contribution of the building products to energy efficiency or other aspects of the sustainable management of the building.

The declaration provides information about the energy and resources that have been utilised, and the extent to which a product contributes to the greenhouse effect, acidification, over-fertilisation, destruction of the ozone layer, or smog. In addition, data is provided regarding technical characteristics that are required for estimation of the performance of the building product within the building, such as life span, thermal and acoustic insulation, or the impact on interior air quality.

With this quantitative information about the environmental performance of building products, the ISO Type III Declaration is targeted to a wide audience: planners, architects, building contractors, real estate companies, facility managers, and, naturally, to companies involved in production and service in the value creation chain, from the raw materials to the building.
