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

This document complements the core rules for the product category of construction products as defined in EN 15804:2012+A2:2019 and is intended to be used as a c-PCR in conjunction with that standard.
This c-PCR applies to products within the scope of CEN/TC 104 and CEN/TC 229, but it may be applicable to other concrete products until they have product specific c-PCRs.
This document applies to concrete and concrete elements for building and civil engineering, to the exclusion of autoclaved aerated concrete and resin bound concrete. Apart from Annex G, it may be used as guidance for glass fibre reinforced 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+A2:2019, this document 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 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.

Nachhaltigkeit von Bauwerken - Umweltproduktdeklarationen - Produktkategorieregeln für Beton und Betonelemente

Dieses Dokument vervollständigt die Grundregeln für die Produktkategorie von Bauprodukten, wie in EN 15804:2012+A2:2019 festgelegt, und ist für die Anwendung als grundlegende Produktkategorieregel (c PCR, en: core product category rule) in Verbindung mit dieser Norm vorgesehen.
Diese c PCR gilt für Produkte, die im Anwendungsbereich von CEN/TC 104 und CEN/TC 229 liegen, darf aber auch für weitere Betonprodukte anwendbar sein, sofern diese über produktspezifische c PCRs verfügen.
Dieses Dokument gilt für Beton und Betonelemente für Gebäude und Ingenieurbauwerke, mit Ausnahme von Porenbeton und Kunstharzbeton. Abgesehen von Anhang G darf es als Leitlinie für glasfaserverstärkten Beton verwendet werden.
Dieses Dokument legt die anzugebenden Parameter und darüber hinaus fest, welche EPD Typen (und Phasen des Lebenszyklus) zu behandeln und welche Regeln zu befolgen sind, um Sachbilanzen (LCI) zu generieren und Wirkungsabschätzungen (LCIA) durchzuführen, und welche Qualität die bei der Erstellung von EPDs verwendeten Daten haben müssen.
Zusätzlich zu den allgemeinen Abschnitten von EN 15804:2012+A2:2019 hat dieses Dokument für Beton und Betonelemente folgende Ziele: Es
-   legt die Systemgrenzen fest,
-   legt die Modellierung und Beurteilung der materialspezifischen Eigenschaften fest,
-   legt die Allokationsverfahren für Multi Output Prozesse entlang der Produktionskette fest,
-   legt die Allokationsverfahren für die Wiederverwendung und das Recycling fest,
-   enthält die Regeln für die Berechnung der Sachbilanz und der Wirkungsabschätzung, die der EPD zugrun¬de liegen,
-   liefert eine Anleitung/spezielle Regeln für die Ermittlung der Referenz Nutzungsdauer (RSL, en: reference service life),
-   gibt eine Anleitung zur Festlegung von Standardszenarien, und
-   gibt eine Anleitung für übliche funktionale Einheiten für Betonelemente.
Dieses Dokument ist für die Anwendung bei der Beurteilung der Herstellungsphase sowie weiterer Phasen (von der Wiege bis zum Werkstor mit Optionen) oder der Beurteilung des gesamten Lebenszyklus (von der Wiege bis zur Bahre) vorgesehen; Voraussetzung dafür ist, dass die Ziele in der Beschreibung der System-grenzen vorschriftsmäßig angegeben sind.
Auf Bauwerksebene liefert eine umfassende Deklaration (von der Wiege bis zur Bahre) ein besseres Gesamtverständnis der Umweltfolgen, die sich aus Beton und Betonelementen ergeben.

Contribution des ouvrages de construction au développement durable - Déclarations environnementales sur les produits - Règles régissant la catégorie de produits pour le béton et les éléments en béton

Le présent document complète les règles de base des catégories de produits applicables aux produits de construction, telles que définies dans la norme EN 15804:2012+A2:2019 avec laquelle elle est destinée à être utilisée conjointement en tant que RCP c.

This document (prEN 16757:2021) has been prepared by Technical Committee CEN/TC 229 “Precast

Concrete Products”, the secretariat of which is held by AFNOR.
This document will supersede EN 16757:2017.
The main changes are:
— implementation of changes brought by the publication of EN 15804:2012+A2:2019;

— change of the numbering of Annexes AA and BB into Annexes F and G respectively.

Introduction

The European Standard EN 15804:2012+A2:2019 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+A2:2019.

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+A2:2019, 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+A2:2019 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+A2:2019. 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, Sustainability of construction works — Framework for assessment of buildings and civil

engineering works

— EN 15978, Sustainability of construction works — Assessment of environmental performance of

buildings — Calculation methods

— EN 15804:2012+A2:2019, 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

1 Scope

This document complements the core rules for the product category of construction products as defined

in EN 15804:2012+A2:2019 and is intended to be used as a c-PCR in conjunction with that standard.

This document 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+A2:2019, this document 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 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.

In addition to the objectives of EN 15804:2012+A2:2019 this document aims to:

— define the parameters to be declared and the way in which they are collated and reported;

— describe 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;

— define rules for the development of scenarios, including 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;

— communicate EPDs and environmental information about concrete and concrete elements;

— ensure that comparisons between construction products are carried out in the context of their use in

the building on the basis of the functional unit.
5.2 Types of EPD with respect to life cycle stages covered
EN 15804:2012+A2:2019 shall apply.

6 Product Category Rules for LCA
6.1 Product category

The product category referred to in this standard includes concrete and concrete elements for building

and civil engineering works.
6.2 Life cycle stages and their information modules to be included
6.2.1 General
In addition to the text of EN 15804:2012+A2:2019:

As all life cycle stages (from A1 to C4 and D) shall be included when assessing a construction work

(building or civil engineering), it is recommended that EPDs prepared cover the same life cycle, i.e. cradle

to grave and module D.
A general description of the life cycle stages is given in Figure 1.
6.2.2 A1-A3, Product stage, information modules
In addition to the text of EN 15804:2012+A2:2019:

NOTE Concrete and concrete elements may contain the following constituents or products (not exhaustive

list):
— aggregates;
— cement;
— water;
— admixtures;
— additions;
— fibres;
— reinforcing steel (for precast concrete elements).

When the full LCI of constituents is not available, impact indicators and aspects from the EPDs complying

to EN 15804:2012+A2:2019 for the constituents or for ready-mixed concrete, covering modules A1 to A3,

can be used for the assessment of module A1 of the concrete or concrete element. If transport is included,

then the impacts and aspects covering modules A1 to A4 can be used for the assessment of modules A1

and A2 (see Figure 2).

Figure 2 — EPD for constituents (top) and for concrete and concrete elements (bottom)

As an example, for the use of aggregate in concrete, when the EPD of aggregate is used, modules A1 to A3

of the aggregate EPD becomes part of modules A1 of concrete EPD and module A4 of aggregate EPD

becomes part of modules A2 of concrete EPD.
