NOTE 4 The assessment of social and economic performances at product level is not covered by this document.
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 the predetermined, environmental and health information that is not covered by Life Cycle Assessment (LCA) for the product, construction process(es) and construction service(s), as relevant;
- 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.

Introduction
!The European Standard EN 15804:2012+A2:2019" 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 harmonized way.
This document provides complementary product category rules !(c-PCR)" for Type III
Environmental Declarations (EPD) specifically for windows and pedestrian doorsets.
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 EN ISO 14025. All common issues for
windows and pedestrian doorsets are covered horizontally in order to minimize intra-sectorial
deviations.
EPD information is expressed in information modules, which allow easy organization and expression of
data packages throughout the lifecycle 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. !Neither EN 15804:2012+A2:2019 nor this document deal with aggregation at the building
level nor do the standards describe the rules for applying EPD in building assessment."
This document deals with a limited number of quantifiable predetermined parameters as defined in
!EN 15804". Future revisions may incorporate additional predetermined parameters.
This document provides the means for developing a Type III environmental declaration for windows
and pedestrian doorsets, thereby supplementing 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 15804:2012+A2:2019, Sustainability of construction works — Environmental product
declarations — Core rules for the product category of construction products;
— EN 15941, Sustainability of construction works — Data quality for environmental assessment of
products and construction work — Selection and use of data;"
— EN 15942, Sustainability of construction works — Environmental product declarations —
Communication formats: business to business;
— EN 15978, Sustainability of construction works — Assessment of environmental performance of
buildings — Calculation method.
1 Scope
This document !provides complementary product category rules (c-PCR)" for Type III
environmental declarations for windows and pedestrian doorsets as defined in EN 14351-1 and
EN 14351-2. Windows and pedestrian doorsets additionally providing fire resistance and/or smoke
control characteristics according to EN 16034 are also covered by this document.
NOTE 1 Windows that incorporate shutters and/or shutter boxes and/or blinds are in scope of this
!c-PCR". For any connected electrical devices (e.g. motors, sensors) — see !6.3.5.2".
!NOTE 2 For wood and wood-based products for use in construction, see EN 16485.
NOTE 3 For building hardware, see EN 17610."
This document complements the core rules for the product category of construction products as defined
in !EN 15804:2012+A2:2019". This document is to be used in conjunction with
!EN 15804:2012+A2:2019", not replace it.
!NOTE 4" The assessment of social and economic performances at product level is not covered by this
document.
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 the predetermined, environmental and health information that is
not covered by Life Cycle Assessment (LCA) for the product, construction process(es) and
construction service(s), as relevant;
— 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.

5 General aspects
5.1 Objective of this !c-PCR"
An EPD according to this document provides quantified environmental information for a window or
pedestrian doorset using a uniform 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 building and other construction works and
identifying those which cause less stress to the environment.
Thus, the objective of this !c-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 doorsets/windows are carried out in the context of their application in
the building;
— the consistent communication of the environmental information of door sets and windows.
Declarations based on this document are not comparative assertions.
NOTE See !EN 15804:2012+A2:2019", 3.4 and EN ISO 14044:2006, 5.3 for more information concerning
