Sustainability of construction works - Environmental product declarations - Product category rules

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.

Foreword
This document (prEN 15804:2008) has been prepared by Technical Committee CEN/TC 350 “Sustainability of
construction works”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
Introduction
This European standard provides Product Category Rules for all construction products. It provides a structure
to ensure that all Environmental Product Declarations (EPD) of construction products, services and
construction processes are derived, controlled and presented in a harmonised way.
The standardisation process has taken place in an open consultation, as required in ISO 14025. All common
issues are covered horizontally (all product types) as far as possible, which minimises vertical (sector specific)
deviations.
The EPD information is expressed in information modules, which allows 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 (summation) to provide complete information for
buildings. This standard does not deal with aggregation for the building level nor does this standard describe
the rules for applying EPD in building assessment. These rules will be found in the future standard WI 350003,
„Use of EPD”.
This standard does not define requirements for developing and operating EPD programs. These requirements
are found in ISO 14025.
The standard deals only with a limited number of indicators for which quantification is available with sufficient
experience. Future revisions may incorporate further agreed indicators.
This European Standard is part of a suite of standards that are intended to provide the means for the
declaration of environmental performance of building products.
Other relevant standards are the future standards:
 prEN 15643-1, Sustainability of construction works - Integrated assessment of building performance -
Part 1: General framework
 prEN 15643-2, Sustainability of construction works - Integrated assessment of building performance -
Part 2: Framework for the assessment of environmental performance

1 Scope
This voluntary European standard provides product category rules for Type III environmental declarations for
all European construction products and services.
The PCR:
 defines the indicators and other parameters to be declared and the way in which they are collated and
reported,
 includes the rules for calculating the Life Cycle Assessment, Life Cycle Inventory or the information
modules underlying an EPD, including the specification of the quality of the applied data,
 describes which stages of a product’s life cycle are considered in the EPD and which processes are
included in the life cycle stages,
 defines rules for the development of scenarios,
 includes the rules for calculating and reporting any relevant additional environmental information for a
product, construction process and service where necessary,
 defines the conditions under which construction products can be compared based on the information
provided by EPD.
For the EPD of services the same rules and requirements apply as for the EPD of construction products.
NOTE In this standard the EPD is an abbreviation for ‘environmental product declaration’, which is intended to be
synonymous with the designation ‘Type III environmental declaration’. In the practice of developing Type III environmental
declarations, programs or their declarations are referred to by various names such as eco-profile, environmental
declaration of product, environmental product declaration (EPD), or environmental profile.

5 General aspects for Product Category Rules for EPD of construction products
and services
5.1 Objectives
The objective of an EPD is to provide an environmental quantification for a product. The purpose of EPD in
the construction sector is to provide the basis for assessing buildings and identifying those, which cause less
stress to the environment. This is accomplished through the communication of verifiable, accurate, not
misleading environmental information for the products and their applications, thereby supporting scientifically
based, fair choices and stimulating the potential for market-driven continuous environmental improvement.
The objective of the PCR is to provide the rules to ensure:
 the provision of verifiable, consistent and comparable data for EPD, based on LCA (covering the whole
life cycle), describing the environmental performance of construction products on a fair and scientific
basis;
 the provision of verifiable, consistent and comparable product related technical data or scenarios for the
assessment of the environmental performance of buildings;
8

---------------------- Page: 10 ----------------------
oSIST prEN 15804:2008
prEN 15804:2008 (E)
 the provision of verifiable, consistent and comparable product related technical data or scenarios for the
assessment of the health and comfort performance of buildings;
 informed comparisons between construction products in the context of their application in a building for
purchasers and users of construction products;
 the communication of the environmental performance of construction products in particular from business
to business, e.g. along the supply chain;
 the communication of the environmental performance of construction products to consumers if relevant,
e.g. in a “do it yourself” store.
Declarations based on these PCR are not comparative assertions.
5.2 Information modules of construction products
In the development of EPD, all relevant environmental aspects of the product throughout its life cycle shall be
taken into consideration and become part of the declaration. If the aspects considered to be relevant are not
calculated for all stages of the life cycle then this shall be stated and justified.
This PCR requires the provision of pre-selected indicators for the “product stage” (see clause 9 for indicators
and clause 6.2 for life cycle stages). In this case the EPD is not based on a LCA covering all life cycle stages
but only on the product stage information module including raw material supply, transports and manufacturing;
it is then said to be “cradle to gate”. There is also the option for calculating pre-selected indicators for other life
cycle stages and information modules such as the “construction stage”, “maintenance” “transport” or “final
deposition” stages.
The data from any information module, calculated according to this PCR is addable with data from any other
module and if all modules from all life cycle stages are added a complete LCA for the construction product is
produced, provided there are no data gaps or overlaps. This is the principle of modularity.
An EPD that includes all life cycle stages, such as the product stage, installation into the building, use and
maintenance, replacements, demolition, recycling and disposal is said to be „cradle to grave” and becomes an
EPD of construction products based on a LCA. Information modules and „cradle to grave” EPD are illustrated
in Figure 1.
The EPD of an assembly or element of construction shall incorporate the results of the EPD or information
modules of all the assembled materials, construction products and processes.
NOTE 1 The EPD of an assembly or element of construction can incorporate the results of the EPD or information
modules of services, e.g. maintenance.
NOTE 2 Information modules can supply information for processes for which there is no EPD available, e.g. a cleaning
process.

NOTE 3 It is possible to have an EPD for a substance or preparation (e.g. cement), for a product (e.g. window), for a
service (e.g. cleaning service as part of maintenance) and for an assembly and/or a construction element (e.g. wall) or a
technical construction service (e.g. elevator).
The requirements of this standard apply to the EPD of construction products. They also apply to EPD of
elements of construction. However the EPD of the element takes into account the quantities of the individual
products included in the element of construction. The same logic applies for complete buildings.
5.3 Comparability of EPD of construction products
Comparison of the environmental performance of construction products using the information supplied by EPD
shall only be carried out on building level. This means comparisons shall be based on
 A common functional unit (see 6.4.1);
 Consideration of all stages of the product’s life cycle;
 The functional equivalent of the building, where relevant to the product.
For example:
 Comparisons carried out using cradle to gate EPD require additional scenarios for the use stage and end
of life stage;
 Comparisons of construction products shall be based on the same conditions for use in the building.
Comparability of EPD of construction products shall be in accordance with the requirements for comparability
as described in the general principle of 5.6 of ISO 14025:2006-07, and detailed in clause 6.7.2. Data
comparability can only be expected between EPD based on the same PCR document. The information
provided for such comparison shall be transparent in order to allow the purchaser or user to understand the
limitations of comparability inherent in the EPD. In order to compare EPD based on information modules,
either the environmental impacts of omitted life cycle stages of the products shall not be significant, or the
data of omitted life cycle stages shall be identical for the compared products within the accepted uncertainty of
the data.
NOTE EPD not covering all life cycle stages may be declarations that have limited or no comparability.
5.4 Additional information
Additional information related to environmental aspects, other than the environmental information derived from
LCA, LCI or information modules is used to complement the pre-set parameters based on LCA, where the
LCA does not cover all relevant environmental aspects of the product’s Life Cycle. In this PCR the following
categories of additional information are addressed:
