Sustainability of construction works - Sustainability assessment 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.

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.
---------------------- Page: 6 ----------------------
oSIST prEN 17472:2020
prEN 17472:2020 (E)

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.
