CEN/TC 350/WG 3 - Products Level

This document supports the data quality assessment and selection of data for product-level Environmental Product Declarations (EPD) according to the core product category rules of EN 15804 and for the environmental performance assessment of buildings according to prEN 15978 1 in a consistent way. It can also be used to assess and select data for the environmental assessment of civil engineering works according to EN 17472.
It defines data quality requirements with respect to temporal, technological and geographical representativeness for the data used to calculate the Life Cycle Assessment (LCA) based indicator results of the EPD and for construction works when applying EPD, life cycle inventory data or other LCA based information, and generates a hierarchy to support the selection of the most appropriate data with regard to data quality. It also addresses the reporting of data quality at product and building level.

This document provides horizontal rules for business-to-consumer communication including benchmarking systems that aim to inform consumers about the life cycle environmental performance of construction products, assembled systems and construction elements. The communication is based on the results of the life cycle of the product, system or element, as incorporated to the construction asset, see EN 15804:2012+A2:2019. B2C communication includes information on benefits and loads beyond the system boundary.
This document is aimed at organizations providing business-to-consumer communication and benchmarking systems and provides guidance on how to develop business-to-consumer communication and common rules for benchmarking methodologies using EPD, see EN 15804, and see EN 15942 for the communication format.
Business-to-consumer communication and benchmarking methodology described in this document is based on a functional unit and cradle-to-grave assessments. B2C communication with no benchmarking is also described in this document.

This document provides the principles and requirements to enable environmental and technical data provided in EPDs for construction products and services, construction elements and integrated technical systems to be used in BIM to assist in the assessment of the environmental performance of a construction works over its life cycle.
This document gives requirements on structuring EPD information using a data template according to ISO 23386 and ISO 23387, to make EPD data machine-interpretable and to enable their integration into information-driven design, construction, use and end-of-life stages.
This document is applicable to structuring generic LCA data for use within a BIM environment, as these data are required in the absence of suitable EPD data to enable assessment of the environmental performance at the construction works level.
The assessment of environmental performance at the construction works level is not covered by this document.

This European standard provides core product category rules (PCR) for Type III environmental declarations for any construction product and construction service.
NOTE   The assessment of social and economic performances at product level is not covered by this standard.
The core PCR:
-   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 and health information, that is not covered by LCA for a product, construction process and construction service where necessary,
-   defines the conditions under which construction products can be compared based on the information provided by EPD.
For the EPD of construction services the same rules and requirements apply as for the EPD of construction products.

This document is applicable to all construction products and services related to buildings and construction works. It specifies and describes the communication format for the information defined in EN 15804 for business-to-business communication to ensure a common understanding through consistent communication of information.
NOTE This document does not deal with business-to-consumer communication and is not intended for that purpose. Business-to-consumer communication format is planned to be the subject of a future document.

This Technical Report provides general guidance to the users of EN 15804 and those preparing complementary Product Category Rules (c-PCR's) by:
—   stating general principles for the use of EN 15804 by CEN Technical Committees for construction products (Product TC's) in order to ensure consistency among the complementary PCR produced by Product TC's;
—   addressing the questions raised by Product TC's, manufacturers or their sub-contractors who provide LCA studies underlying an Environmental Product Declaration (EPD) and by EPD programme operators who include c-PCR of specific subcategories in their PCR registry.

This standard is applicable to building products, processes and services. The product category rules specify requirements for all building products in accordance with ISO 21930 (proposed to be implemented as EN ISO 21930 in another Work Item) and ISO 14025 for the intended audience whether business or consumers. This standard supports the application of environmental product declarations for the assessment of the environmental performance of buildings and for the assessment of the health & comfort performance of buildings in the framework of the integrated performance of buildings.

This European standard provides core product category rules (PCR) for Type III environmental declarations for any construction product and construction service. NOTE The assessment of social and economic performances at product level is not covered by this standard. The core PCR: - 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 and health information, that is not covered by LCA for a product, construction process and construction service where necessary, - defines the conditions under which construction products can be compared based on the information provided by EPD. For the EPD of construction services the same rules and requirements apply as for the EPD of construction products.

Identical to EN 15804+A1 amendment to add additional indicators. Indicators could be : - land use (biodiversity, soil quality), - particulate matter (PM 10), - human tox, - eco tox, - ionizing radiation, - water scarcity, Note oft he secretary: - If it turns out that it is not feasible to have additional indicators a justification has to be developed. - For each indicator this applicability or not should be indicating and justify - Coordination with WG1 - jwg meeting planned however perspective can be different -Pay attention to the use of indicators according to the context. - address third party assessment issue

This Technical Report supports the development of Environmental Product Declarations (EPD).
It assists in using generic data according to the core product category rules (prEN 15804) during the preparation of EPD of construction products, processes and services in a consistent way, and also in the application of generic data in the environmental performance assessment of buildings according to prEN 15978.
The requirements for the use of generic data are described in prEN 15804.
