Sustainability of construction works - Sustainability assessment of civil engineering works - Calculation methods
The document provides the specific methods and requirements for the assessment of environmental, economic and social performances of a civil engineering works while taking into account the civil engineering work’s functionality and technical characteristics. The primary objective of this document is to help in the decision making for a project by providing a standardized method for enabling comparability of scheme options. The document has not been designed to be used for the development of sustainability labels however, this use is not precluded.
The assessment of environmental and economic performances of a civil engineering works is based on Life Cycle Assessment (LCA), Life Cycle Cost (LCC), Whole-Life Cost (WLC) and other quantified environmental and economic information. The approach to the assessment covers all stages of the civil engineering works life cycle and includes all civil engineering works related construction products, processes and services, used over its life cycle. The document is applicable to new and existing civil engineering works and refurbishment projects. The environmental performance is based on data obtained from Environmental Product Declarations (EPD) and additional indicators.
The assessment of social performance differs from the assessment of economic and environmental aspects because it requires both quantitative and descriptive approaches.
The document provides requirements for:
- the description of the object of assessment;
- the system boundary that applies at the civil engineering works level;
- the procedure to be used for the analysis;
- definition of the indicators to be declared, information to be provided and the way in which they are collated and reported,
- presentation of the results in reporting and communication;
- the data necessary for the application of the standard and calculation.
Whenever the asset includes building(s) as part of the civil engineering works the building(s) will be assessed using EN 15978 for environmental performance, EN 16309 for social performance and EN 16627 for economic performance.
Nachhaltigkeit von Bauwerken - Bewertung der Nachhaltigkeit von Ingenieurbauwerken - Rechenverfahren
Das Dokument stellt die speziellen Verfahren und Anforderungen für die Bewertung der umweltbezogenen, ökonomischen und sozialen Qualität eines Ingenieurbauwerkes unter Berücksichtigung der Funktionalität und technischen Eigenschaften des Ingenieurbauwerks bereit. Das Hauptziel dieses Dokumentes besteht darin, zur Entscheidungsfindung bei einem Projekt beizutragen, indem ein genormtes Verfahren bereitgestellt wird, das die Vergleichbarkeit von Programmoptionen ermöglicht. Das Dokument wurde nicht dafür ausgelegt, um für die Entwicklung von Nachhaltigkeitslabels verwendet zu werden, wobei diese Verwendung jedoch nicht ausgeschlossen ist.
Die Bewertung der umweltbezogenen und ökonomischen Qualität eines Ingenieurbauwerks beruht auf der Ökobilanz (LCA), den Lebenszykluskosten (LCC), den Lebenszykluskosten im weiteren Sinne (WLC) sowie weiteren quantifizierten umweltbezogenen und ökonomischen Angaben. Der Ansatz für die Bewertung umfasst alle Phasen des Lebenszyklus des Ingenieurbauwerkes und schließt alle mit dem Ingenieurbauwerk verbundenen Bauprodukte, Prozesse und Dienstleistungen ein, die über dessen Lebenszyklus verwendet werden. Das Dokument ist für neue und bereits bestehende Ingenieurbauwerke sowie für Erneuerungs¬projekte anwendbar. Die umweltbezogene Qualität beruht auf Daten, die von Umweltproduktdeklarationen (EPD) und weiteren Indikatoren stammen.
Die Bewertung der sozialen Qualität unterscheidet sich von der Bewertung der ökonomischen und umweltbezogenen Aspekte, da hierfür sowohl quantitative als auch beschreibende Ansätze erforderlich sind.
Das Dokument stellt Anforderungen bereit für:
- die Beschreibung des Gegenstandes der Bewertung;
- die Systemgrenze, die auf Ebene des Ingenieurbauwerks gilt;
- das für die Analyse anzuwendende Verfahren;
- die Definition der zu deklarierenden Indikatoren, der bereitzustellenden Angaben und der Art, wie diese auf Vollständigkeit überprüft und kommuniziert werden;
- die Darstellung der Ergebnisse bei der Berichterstattung und Kommunikation;
- die Daten, die für die Anwendung der Norm und die Berechnung erforderlich sind.
Wenn der Sachwert (ein) Gebäude als Teil des Ingenieurbauwerks einschließt, werden das/die Gebäude hinsichtlich der umweltbezogenen Qualität nach EN 15978, hinsichtlich der sozialen Qualität nach EN 16309 und hinsichtlich der ökonomischen Qualität nach EN 16627 bewertet.

Trajnostnost gradbenih objektov - Ocenjevanje trajnostnosti gradbenih inženirskih objektov - Računske metode
Dokument podaja posebne metode in zahteve za ocenjevanje okoljskih, gospodarskih ter družbenih učinkov gradbenih inženirskih objektov, pri čemer upošteva funkcionalnost in tehnične značilnosti gradbenega inženirskega objekta. Glavni cilj tega dokumenta je olajšati postopke odločanja pri posameznem projektu z zagotavljanjem standardizirane metode za omogočanje primerljivosti možnosti sistemov. Dokument ni namenjen uporabi za razvoj trajnostnih oznak, vendar takšna uporaba ni izključena.
Ocenjevanje okoljskih in gospodarskih učinkov gradbenih inženirskih objektov temelji na oceni življenjskega cikla (LCA), stroških življenjskega cikla (LLC), celotnih stroških v življenjski dobi (WLC) ter drugih količinsko opredeljenih okoljskih in gospodarskih podatkih. Pristop k oceni zajema vse faze življenjskega cikla gradbenih inženirskih objektov ter vključuje vse gradbene proizvode, postopke in storitve, povezane z gradbenimi inženirskimi objekti, ki se uporabljajo skozi njihov celoten življenjski cikel. Ta dokument se uporablja za nove in obstoječe gradbene inženirske objekte in obnovitvene projekte. Ocena okoljskega učinka temelji na podatkih, pridobljenih iz okoljskih deklaracij o proizvodih (EPD) in dodatnih kazalnikov.
Ocena družbenega učinka se razlikuje od ocene gospodarskih in okoljskih vidikov, saj hkrati zahteva tako kvantitativni kot deskriptivni pristop.
Dokument podaja zahteve za:
– opis predmeta ocene;
– mejo sistema, ki velja za raven gradbenih inženirskih objektov;
– postopek, ki ga je treba uporabljati za analizo;
– opredelitev kazalnikov, ki jih je treba deklarirati, podatke, ki jih je treba navesti ter način njihovega zbiranja in sporočanja;
– predstavitev rezultatov pri poročanju in komuniciranju;
– podatke, potrebne za uporabo standarda in za izračun.
Kadar sredstvo v okviru gradbenih inženirskih objektov vključuje zgradbo/zgradbe, se za ocenjevanje zgradbe/zgradb uporabljajo standard EN 15978 za okoljski učinek, standard EN 16309 za družbeni učinek in standard EN 16627 za gospodarski učinek.

Introduction
This document provides rules for the assessment of the sustainability of civil engineering works including
environmental, economic and social aspects.
Figure 1 illustrates how the assessment of the environmental, economic and social performances fits
within the concept of the sustainability assessment of a civil engineering works.
NOTE The outer box with the dashed line represents the area standardized by CEN/TC 350 – Sustainability of
construction works.
Figure 1 — Concept of sustainability assessment of civil engineering works
Those economic, social or environmental requirements not expressed in the sustainability assessment
are communicated, too.
This document supports quantification of the contribution of the assessed civil engineering works to
sustainable construction and sustainable development.
The evaluation of technical and functional performance is beyond the scope of this document. Technical
and functional characteristics are taken into account here by reference to the functional equivalent, which
also forms a basis for comparison of the results of assessments.
Although the assessment of technical and functional performance does not form part of this series of
standards, their interrelationship with environmental, social and economic performance is a prerequisite
for an assessment of sustainability of construction works and, therefore, is taken into account, as
illustrated in Figure 1.

SIST EN 17472:2022
EN 17472:2022 (E)
The method of assessment of sustainability described in this document is based on a life cycle approach
and provides a consistent model for describing and recording the civil engineering works and its life cycle
for assessing the environmental, economic and social performance. For the assessment of the three
aspects, the same reference study period is used.
The assessment of social performance differs from the assessment of economic and environmental
aspects because it requires both quantitative and descriptive approaches.
The document sets requirements for:
— the description of the object of assessment;
— the system boundary that applies at the civil engineering works level;
— the procedure to be used for the analysis;
— definition of the indicators to be declared, information to be provided and the way in which they are
collated and reported;
— presentation of the results in reporting and communication; and
— the data necessary for the application of the standard and calculation.
The economic assessment is undertaken at the civil engineering works level. However, it requires
technical and cost information about individual products and components within the civil engineering
works and its services and systems, including service life data, type and frequency of maintenance,
replacement and repair, and deconstruction and disposal. This information is used as input quantities for
the calculation of cost in the life cycle of the civil engineering works.
The framework and the general requirements for sustainability assessments of civil engineering works
are specified in EN 15643. Further documents on sustainability assessment have already been developed
by CEN/TC 350 or are currently under development. Table 1 gives an overview on relevant standards
related to sustainability of construction works. Each standard has been assigned to either the framework
level, the works level, or the product level according to the specifications it contains.

1 Scope
This document establishes the requirements and specific methods for the assessment of environmental,
economic and social performances of a civil engineering works while taking into account the civil
engineering works’ functionality and technical characteristics. By the means of this document the
decision making for a project is supported by providing a standardized method for enabling
comparability of scheme options.
The assessment of environmental and economic performances of a civil engineering works is based on
Life Cycle Assessment (LCA), Life Cycle Cost (LCC), Whole-Life Cost (WLC) and other quantified
environmental and economic information. The approach to the assessment covers all stages of the civil
engineering works life cycle and includes all civil engineering works related construction products,
processes and services, used over its life cycle.
This document is applicable to new and existing civil engineering works and refurbishment projects. The
environmental performance is based on data obtained from Environmental Product Declarations (EPD)
and additional indicators.
This document is not applicable for the assessment of the environmental, social and economic
performance of building(s) as part of the civil engineering works; instead, EN 15978, EN 16309 and
EN 16627 apply.

Introduction
The purpose of this document is to provide rules for the assessment of the sustainability of civil
engineering works including environmental, economic and social aspects.
Figure 1 illustrates how the assessment of the environmental, economic and social performances fits
within the concept of the sustainability assessment of a civil engineering works.
Figure 1 — Concept of sustainability assessment of civil engineering works
This document supports quantification of the contribution of the assessed civil engineering works to
sustainable construction and sustainable development.
The evaluation of technical and functional performance is beyond the scope of this document. Technical
and functional characteristics are taken into account here by reference to the functional equivalent, which
also forms a basis for comparison of the results of assessments.
This document is intended to support the decision-making process and documentation of the assessment
of the sustainability of a civil engineering work.

In this document, the method of assessment of sustainability is based on a life cycle approach. It is
important to use a consistent model for describing and recording the civil engineering works and its life
cycle for assessing the environmental, economic and social performance. The same reference study
period is used for all three elements of the assessment.
The general requirements for sustainability assessment of civil engineering works are described in
EN 15643-5. Other standards developed by CEN/TC 350 in this area, and how they are related to this
document, are shown in Figure 2.
Figure 2 — Work programme of CEN/TC 350
NOTE 1 The environmental assessment at civil engineering works level requires information from products and
services (EN 15804).
NOTE 2 The economic assessment is undertaken at the civil engineering works level. However, it requires
technical and cost information about individual products and components within the civil engineering works and
its services and systems, including service life data, type and frequency of maintenance, replacement and repair,
and deconstruction and disposal. This information is used as input quantities for the calculation of cost in the life
cycle of the civil engineering works.

1 Scope
The document provides the specific methods and requirements for the assessment of environmental,
economic and social performances of a civil engineering works while taking into account the civil
engineering work’s functionality and technical characteristics. The primary objective of this document is
to help in the decision making for a project by providing a standardized method for enabling
comparability of scheme options. The document has not been designed to be used for the development
of sustainability labels however, this use is not precluded.
The assessment of environmental and economic performances of a civil engineering works is based on
Life Cycle Assessment (LCA), Life Cycle Cost (LCC), Whole-Life Cost (WLC) and other quantified
environmental and economic information. The approach to the assessment covers all stages of the civil
engineering works life cycle and includes all civil engineering works related construction products,
processes and services, used over its life cycle. The document is applicable to new and existing civil
engineering works and refurbishment projects. The environmental performance is based on data
obtained from Environmental Product Declarations (EPD) and additional indicators.
The assessment of social performance differs from the assessment of economic and environmental
aspects because it requires both quantitative and descriptive approaches.
The document provides requirements for:
— the description of the object of assessment;
— the system boundary that applies at the civil engineering works level;
— the procedure to be used for the analysis;
— definition of the indicators to be declared, information to be provided and the way in which they are
collated and reported,
— presentation of the results in reporting and communication;
— the data necessary for the application of the standard and calculation.
Whenever the asset includes building(s) as part of the civil engineering works the building(s) will be
assessed using EN 15978 for environmental performance, EN 16309 for social performance and
EN 16627 for economic performance.
