Sustainability of construction works - Environmental product declarations - Product Category Rules for concrete and concrete elements

This European Standard complements the core rules for the product category of construction products as defined in EN 15804:2012+A1:2013 and is intended to be used in conjunction with that standard.
This European Standard applies to concrete and concrete elements for building and civil engineering, excluded autoclaved aerated concrete.
This document defines the parameters to be reported, what EPD types (and life cycle stages) to be covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804:2012+A1:2013, this European Standard for concrete and concrete elements:
-   defines the system boundaries;
-   defines the modelling and assessment of material-specific characteristics;
-   defines allocation procedures for multi-output processes along the production chain;
-   defines allocation procedures for reuse and recycling;
-   includes the rules for calculating the LCI and the LCIA underlying the EPD;
-   provides guidance/specific rules for the determination of the reference service life (RSL);
-   gives guidance on the establishment of default scenarios;
-   gives guidance on default functional units for concrete elements.
This document is intended to be used either for cradle to gate, cradle to gate with options or cradle to grave assessment, provided the intentions are properly stated in the system boundary description.
Within the construction works context, a cradle to grave declaration delivers a more comprehensive understanding of the environmental impact associated with concrete and concrete elements.

Introduction
The European Standard EN 15804:2012+A1:2013 provides core rules for all construction products and
services.
It provides a structure to ensure that all Environmental Product Declarations (EPD) of construction
products, construction services and construction processes are derived, verified and presented in a
harmonized way.
This European Standard provides additional rules for Environmental Product Declarations (EPD)
specifically for concrete and concrete elements. It complements the core rules for all construction
products and services as established in EN 15804:2012+A1:2013.
An EPD communicates verifiable, accurate, non-misleading environmental information for products and
their applications, thereby supporting scientifically based, fair choices and stimulating the potential for
market-driven continuous environmental improvement.
The standardization process has taken place in accordance with ISO 14025. All common issues are
covered horizontally for all product types in order to minimize vertical (branch specific) deviations. All
common issues are covered horizontally for all concrete and concrete elements in order to minimize
intra-sectorial deviations.
EPD information is expressed in information modules as defined in EN 15804:2012+A1:2013, which
allow easy organization and expression of data packages throughout the life cycle of concrete and
concrete elements. The approach requires that the underlying data should be consistent, reproducible
and comparable.
In line with EN 15804:2012+A1:2013 the EPD is expressed in a form that allows aggregation (addition)
to provide complete information for buildings. This standard does not deal with aggregation at the
building level nor does this standard describe the rules for applying EPD in a building assessment.
The standard deals with a limited number of quantifiable parameters as predefined in
EN 15804:2012+A1:2013. Future revisions of EN 15804 may lead to the incorporation in this standard
of additional predetermined parameters. This European Standard provides the means for developing a
Type III environmental declaration of concrete and concrete elements in the context of the suite of
standards that are intended to assess the sustainability of construction works.
This suite of standards includes:
— EN 15643-1, Sustainability of construction works —Sustainability assessment of buildings — Part 1:
General framework
— EN 15643-2, Sustainability of construction works — Assessment of buildings — Part 2: Framework
for the assessment of environmental performance
— EN 15978, Sustainability of construction works — Assessment of environmental performance of
buildings —Calculation methods
— EN 15804:2012+A1:2013, Sustainability of construction works — Environmental product
declaration — Core rules for the product category of construction products
— CEN/TR 15941, Sustainability of construction works — Environmental product declarations —
Methodology for selection and use of generic data
— EN 15942, Sustainability of construction works — Environmental product declarations —
Communication format - business to business
— CEN/TR 16970:2016, Sustainability of construction works - Guidance for the implementation of
