Sustainability of construction works - Environmental product declarations - Product Category Rules for precast concrete products
This document offers product category rules (PCR) guidance for the development of Type III environmental declarations for precast concrete products according to EN 15804.
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 what quality data to be used in the development of EPDs.
Additional to the common parts of EN 15804, this European Standard for precast concrete products:
- 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 precast concrete products.
This document is intended to be used either for cradle to gate, cradle to gate with options or cradle to grave assessment, provided the intention is properly stated in the system boundary description.
Nachhaltigkeit von Bauwerken - Umweltproduktdeklarationen - Produktkategorieregeln für vorgefertigte Betonerzeugnisse
Diese Europäische Norm enthält Produktkategorieregeln (PCR) für Umweltdeklarationen Typ III für Beton-fertigteile entsprechend EN 15804.
Dieses Dokument legt die zu dokumentierenden Parameter 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 Qualitätsdaten bei der Entwicklung von EPDs zu verwenden sind.
Zusätzlich zu den allgemeinen Abschnitten von EN 15804 hat die vorliegende Europäische Norm für Betonfertigteile das Ziel: sie
- legt die Systemgrenzen fest;
- legt die Modellierung und Bewertung 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 LCI und der Wirkungsabschätzung, die der EPD zugrunde liegen;
- liefert eine Anleitung/spezielle Vorschriften für die Ermittlung der Referenz-Nutzungsdauer (RSL);
- gibt eine Anleitung zur Festlegung von Normszenarien;
- gibt eine Anleitung für normkonforme Funktionseinheiten für Betonfertigteile.
Dieses Dokument ist vorgesehen, entweder für die Produktionsphase (Wiege bis Werkstor), die Produktionsphase (Wiege bis Werkstor) mit Optionen oder Bewertung des Lebenszyklus (Wiege bis Bahre) verwendet zu werden, vorausgesetzt, dass der Zweck ordnungsgemäß in der Beschreibung der Systemgrenze festgelegt ist.

Foreword
This document (prEN 16757:2014) has been prepared by Technical Committee CEN/TC 229 “Precast
Concrete Products”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
Introduction
This European Standard provides rules for Environmental Product Declarations (EPD) specifically for precast
concrete products. It complements the core product category rules for all construction products and services
as established in EN 15804.
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 standardisation process has taken place in accordance with EN 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 precast concrete products in order to minimize intra-sectoral deviations.
EPD information is expressed in information modules as defined in EN 15804, which allow easy organisation
and expression of data packages throughout the life cycle of the product. The approach requires that the
underlying data should be consistent, reproducible and comparable.
In line with EN 15804 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 predetermined parameters in EN 15804. Future
revisions may lead to the incorporation of additional predetermined parameters. This European Standard
provides the means for developing a Type III environmental declaration of precast concrete products in the
context of a 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 method.
EN 15804, 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
formats: business to business.
