Sustainability of construction works - Framework for assessment of buildings and civil engineering works

This document provides principles and requirements for the assessment of environmental, social and economic performance of buildings and civil engineering works taking into account their technical characteristics and functionality. Assessments of environmental, social and economic performance are the three aspects of sustainability assessment of buildings and civil engineering works, or combination thereof, (hereafter referred to as “construction works”).
The framework applies to all types of construction works, both new and existing, and it is relevant for the assessment of the environmental, social and economic performance of new construction works over their entire life cycle, and of existing construction works over their remaining service life and end of life stage.
The sustainability assessment of construction works concentrates on the assessment of environmental, social and economic aspects and impacts of construction works expressed with quantifiable indicators. It includes the assessment of a construction works’ influence on the environmental, social and economic aspects and impacts on the local area (area of influence) and of the local infrastructure beyond the curtilage of the building and the civil engineering works. It excludes environmental, social and economic risk assessment.
The European Standards developed under this framework do not set the rules for how the different assessment methodologies may provide valuation methods; nor do they prescribe levels orclasses for measuring performance.
NOTE   Valuation methods, levels, classes or benchmarks can be prescribed in the requirements for environmental, social and economic performance in the client’s brief, construction regulations, national standards, national codes of practice, construction works assessment and certification schemes, etc.
The rules for assessment of environmental, social and economic aspects of organizations, such as management systems, are not included within this framework. However, the consequences of decisions or actions that influence the environmental, social and economic performance of the object of assessment are taken into account.

Nachhaltigkeit von Bauwerken - Allgemeine Rahmenbedingungen zur Bewertung von Gebäuden und Ingenieurbauwerken

Dieses Dokument stellt die Grundsätze und Anforderungen für die Bewertung von Gebäuden und Ingenieurbauwerken hinsichtlich ihrer umweltbezogenen, sozialen und ökonomischen Qualität unter Berücksichtigung ihrer technischen Eigenschaften und Funktionalität bereit. Die Bewertungen der umweltbezogenen, sozialen und ökonomischen Qualität stellen die drei Aspekte der Nachhaltigkeitsbewertung von Gebäuden und Ingenieurbauwerken oder einer Kombination derselben (nachfolgend als „Bauwerke“ bezeichnet) dar.
Die Rahmenbedingungen gelten für alle Arten von Bauwerken, für neue wie für Bestandsbauten, und sind für die Bewertung der umweltbezogenen, sozialen und ökonomischen Qualität bei neuen Bauwerken über deren gesamten Lebenszyklus und bei Bestandsbauten für deren restliche Nutzungsdauer und die Entsorgungsphase maßgeblich.
Die Nachhaltigkeitsbewertung von Bauwerken legt den Schwerpunkt auf die Bewertung der umweltbezogenen, sozialen und ökonomischen Aspekte und Auswirkungen von Bauwerken mittels quantitativer Indikatoren. Sie schließt die Bewertung des Einflusses eines Bauwerks auf die umweltbezogenen, sozialen und ökonomischen Aspekte und Auswirkungen auf die Region (das Einflussgebiet) und die lokale Infrastruktur über das Grundstück des Gebäudes und des Ingenieurbauwerks hinaus ein. Sie schließt die umweltbezogene, soziale und ökonomische Risikobewertung ein.
Die unter diesen Rahmenbedingungen erarbeiteten Europäischen Normen enthalten weder Festlegungen hinsichtlich der unterschiedlichen Verfahrensweisen bei der Beurteilung von Bauwerken zu Bewertungsverfahren, noch schreiben sie Grenzwerte oder Klassen für die Ermittlung der Qualität vor.
ANMERKUNG   Bewertungsverfahren, Grenzwerte, Klassen oder Richtwerte können in den umweltbezogenen, sozialen und ökonomischen Qualitätsanforderungen im Lastenheft des Auftraggebers, durch gesetzliche Bestimmungen im Bauwesen, in nationalen Normen, in nationalen Verfahrensregeln, in Programmen zur Beurteilung oder Zertifizierung von Bauwerken usw. festgelegt sein.
Regeln zur Bewertung der umweltbezogenen, sozialen und ökonomischen Aspekte von Organisationen, wie Managementsysteme, sind in diesem Leitfaden nicht enthalten. Jedoch werden die Folgen von Entscheidungen oder Maßnahmen, die die umweltbezogene, soziale und ökonomische Qualität des bewerteten Objektes beeinflussen, berücksichtigt.

Contribution des ouvrages de construction au développement durable - Cadre pour l’évaluation des bâtiments et des ouvrages de génie civil

Le présent document énonce les principes et les exigences de l’évaluation des performances environnementales, sociales et économiques des bâtiments et des ouvrages de génie civil en tenant compte de leurs caractéristiques techniques et fonctionnelles. Les évaluations des performances environnementales, sociales et économiques sont les trois aspects de l’évaluation de la contribution des bâtiments et des ouvrages de génie civil, ou d’une combinaison de ceux ci, (ci après dénommés « ouvrages de construction ») au développement durable.
Le cadre méthodologique s’applique à tous les types d’ouvrages de construction, neufs ou existants, pour l’évaluation des performances environnementales, sociales et économiques : pour les ouvrages de construction neufs tout au long de leur cycle de vie, et pour les ouvrages de construction existants pour leur durée de vie résiduelle et leur phase de fin de vie.
L’évaluation de la contribution des ouvrages de construction au développement durable se concentre sur l’évaluation des aspects et impacts environnementaux, sociaux et économiques des ouvrages de construction exprimés à l’aide d’indicateurs quantifiables. Elle inclut l’évaluation de l’influence d’un ouvrage de construction pour les aspects et impacts environnementaux, sociaux et économiques sur la zone locale (zone d’influence) et ceux de l’infrastructure locale au delà du périmètre du bâtiment et de l’ouvrage de génie civil. Elle exclut l’évaluation des risques environnementaux, sociaux et économiques.
Les Normes européennes élaborées dans ce cadre méthodologique ne définissent pas de règles concernant la façon dont les différentes méthodologies d’évaluation peuvent fournir des méthodes d’attribution de valeur. Elles ne prescrivent pas non plus de niveaux ou de classes pour situer les performances.
NOTE   Des méthodes de notation, des niveaux, des classes ou des références comparatives peuvent être prescrits dans les exigences en matière de performances environnementales, sociales et économiques du programme du maître d’ouvrage, des réglementations du secteur de la construction, des normes nationales, des codes de bonnes pratiques nationaux, des programmes d’évaluation des ouvrages de construction et de certification, etc.
Les règles de l’évaluation des aspects environnementaux, sociaux ou économiques des organisations, telles que les systèmes de management, ne sont pas incluses dans ce cadre méthodologique. En revanche, les conséquences des décisions ou actions ayant un impact sur les performances environnementales, sociales et économiques de l’objet de l’évaluation sont prises en compte.

Introduction

This document forms part of a series of European Standards, written by CEN/TC 350, that provide a

system for the sustainability assessment of buildings and civil engineering works using a life cycle

approach. The sustainability assessment quantifies aspects and impacts to assess the environmental,

social and economic performance of buildings and civil engineering works using quantifiable indicators

measured without value judgements. The purpose of this series of standards is to enable comparability

of the results of assessments. This series of European Standards does not set benchmarks or levels of

performance.

This series of standards will allow the sustainability assessment, i.e. the assessment of environmental,

social and economic performance of a builings and/or civil engineering works, to be made concurrently

and on an equal footing, on the basis of the technical characteristics and functionality of the object of

assessment.

The sustainability assessment of buildings and civil engineering works uses different types of

information. The results of a sustainability assessment of a building and/or civil engineering works

provide information on the different types of indicators, the related works scenarios, and the life cycle

stages included in the assessment.

In carrying out assessments, scenarios and a functional equivalent are determined at the construction

works level. Assessment at the construction works level means that the descriptive model of the works

with the major technical and functional requirements has been defined in the client’s brief or in the

regulations, as illustrated in Figure 1.

Assessments can be undertaken either for the whole building or civil engineering works, for a part of the

works or for a combination of several buildings and/or civil engineering works.

Although the evaluation of technical and functional performance is beyond the scope of this series of

standards, the technical and functional characteristics are considered within this framework by reference

to the functional equivalent. The functional equivalent takes into account the technical and functional

requirements and forms the basis for comparisons of the results of the assessment.

Any particular demands for, or related to, the environmental, social and economic performance defined

in the client’s brief, or in regulations, may be declared and communicated. Figure 1 shows how the

functional equivalent, and the technical and functional characteristics that differ from those required,

either by the client’s brief or through regulations, are to be declared and communicated with the results

of the assessment.

NOTE The outer box with the dotted line represents the area standardized by CEN/TC 350.

Figure 1 — Concept of sustainability assessment of construction works

In concept, the integrated construction works performance incorporates environmental, social and

economic performance as well as the technical and functional performance, and these are intrinsically

related to each other. 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.

The users’ activities associated with the constructed asset (referred to as “users’ activities”) are part of

the assessment of construction works. These can include, for example, the fuel consumed by the cars

users of a road as part of the assessment of infrastructure, or the energy used for commuting to and from

a building, as part of a building assessment.

It is advisable to carry out an assessment at the earliest opportunity during the conceptual stages of a

construction or refurbishment project such as in the initial planning stage in order to provide a broad

estimate of the environmental performance, social performance and economic performance. As the

project evolves, the assessment can be periodically reviewed and updated to support decision-making. A

final assessment (as-built) should be carried out. The results of this final assessment can be used to

inform all parties concerned, and also serve as the database for future new similar projects.

This framework is the general framework for sustainability assessment of buildings and civil engineering

works. The purpose of this EN 15643 is to provide a framework with principles, requirements and

guidelines for the assessment of the environmental, social and economic performance of a building

and/or civil engineering works or combination thereof at the “framework level”. This document has been

drafted by combining the previously publishled 5 parts of the framework standards; i.e. EN 15643-1, −2,

−3, −4 and −5 into one framework standard.

1 Scope

This document provides principles and requirements for the assessment of environmental, social and

economic performance of buildings and civil engineering works taking into account their technical

characteristics and functionality. Assessments of environmental, social and economic performance are

the three aspects of sustainability assessment of buildings and civil engineering works, or combination

thereof, (hereafter referred to as “construction works”).

The framework applies to all types of construction works, both new and existing, and it is relevant for the

assessment of the environmental, social and economic performance of new construction works over their

entire life cycle, and of existing construction works over their remaining service life and end of life stage.

The sustainability assessment of construction works concentrates on the assessment of environmental,

social and economic aspects and impacts of construction works expressed with quantifiable indicators.

It includes the assessment of a construction works’ influence on the environmental, social and economic

aspects and impacts on the local area (area of influence) and of the local infrastructure beyond the

curtilage of the building and the civil engineering works. It excludes environmental, social and economic

risk assessment.

The European Standards developed under this framework do not set the rules for how the different

assessment methodologies may provide valuation methods; nor do they prescribe levels or classes for

measuring performance.

NOTE Valuation methods, levels, classes or benchmarks can be prescribed in the requirements for

environmental, social and economic performance in the client’s brief, construction regulations, national standards,

national codes of practice, construction works assessment and certification schemes, etc.

The rules for assessment of environmental, social and economic aspects of organizations, such as

management systems, are not included within this framework. However, the consequences of decisions

or actions that influence the environmental, social and economic performance of the object of assessment

are taken into account.
