Sustainability of construction works - Environmental product declarations - Core rules for the product category of construction products

This European standard provides core product category rules (PCR) for Type III environmental declarations for any construction product and construction service.
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.

EN 15804:2012 (E) 5 Introduction This European standard provides core product category 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 harmonised way.

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 minimise vertical (branch specific) deviations. EPD information is expressed in information modules, 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. 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. Future revisions may incorporate additional predetermined parameters. This European Standard provides the means for developing a Type III environmental declaration of construction products and is part 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;  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. SIST EN 15804:2012

EN 15804:2012 (E) 6 1 Scope 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. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

EN 15804:2012 (E) 12 5 General aspects 5.1 Objective of the Core PCR An EPD according to this standard provides quantified environmental information for a construction product or service on a harmonized and scientific basis. It also provides information on health related emissions to indoor air, soil and water during the use stage of the building. The purpose of an EPD in the construction sector is to provide the basis for assessing buildings and other construction works, and identifying those, which cause less stress to the environment.

Thus, the objective of the core PCR is to ensure:  the provision of verifiable and consistent data for an EPD, based on LCA;  the provision of verifiable and consistent product related technical data or scenarios for the assessment of the environmental performance of buildings;  the provision of verifiable and consistent product related technical data or scenarios potentially related to the health of users for the assessment of the performance of buildings;  that comparisons between construction products are carried out in the context of their application in the building;  the communication of the environmental information of construction products from business to business;  the basis, subject to additional requirements, for the communication of the environmental information of construction products to consumers. Declarations based on this standard are not comparative assertions. NOTE See definition 3.4 and ISO14044:2006, clause 5.1 for more information concerning LCA used for comparative assertion. 5.2 Types of EPD with respect to life cycle stages covered The LCA based information in an EPD may cover (see Figure 1):  The product stage only. Such an EPD covers raw material supply, transport, manufacturing and associated processes; this EPD is said to be “cradle to gate” and becomes an EPD based on information modules A1 to A3;  The product stage and selected further life cycle stages. Such an EPD is said to be “cradle to gate with options” and becomes an EPD based on information modules A1 to A3 plus other selected optional modules, e.g. end-of-life information modules C1 to C4. Information module D may be included in this EPD;  The life cycle of a product according to the system boundary (see 6.3.4). In this case the EPD covers the product stage, installation into the building, use and maintenance, replacements, demol
