Sustainability of construction works - Sustainability assessment of buildings - Part 1: General framework
This European Standard provides the general principles and requirements, expressed through a series of standards, for the assessment of buildings in terms of environmental, social and economic performance taking into account technical characteristics and functionality of a building. The assessment will quantify the contribution of the assessed construction works to sustainable construction and sustainable development. The framework applies to all types of buildings and it is relevant for the assessment of the environmental, social and economic performance of new buildings over their entire life cycle, and of existing buildings over their remaining service life and end of life stage. The standards developed under this framework do not set the rules for how the different building assessment schemes may provide valuation methods. Nor do they prescribe levels, classes or benchmarks for measuring performance. NOTE Valuation methods, levels, classes or benchmarks may be prescribed in the requirements for environmental,
social and economic performance in the client’s brief, building regulations, national standards, national codes of practice, certification schemes, etc. The rules for assessment of environmental, social or economic aspects of organizations 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 - Bewertung der Nachhaltigkeit von Gebäuden - Teil 1: Allgemeine Rahmenbedingungen
Diese Europäische Norm ist Teil einer Reihe Europäischer Normen und enthält die allgemeinen Grundsätze und Anforderungen an die Bewertung von Gebäuden hinsichtlich ihrer umweltbezogenen, sozialen und ökonomischen Qualität unter Berücksichtigung der technischen Eigenschaften und Funktionalität eines Gebäudes. Mit der Nachhaltigkeitsbewertung wird der Beitrag gemessen, den die bewerteten Bauwerke zu nachhaltigen Bauwerken und einer nachhaltigen Entwicklung leisten.
Die Rahmenbedingungen gelten für alle Arten von Gebäuden und sind für die Bewertung der umwelt-bezogenen, sozialen und ökonomischen Qualität bei neuen Gebäuden über deren gesamten Lebenszyklus und bei Bestandsgebäuden für deren restliche Lebensdauer und die Entsorgungsphase maßgeblich.
Die unter diesen Rahmenbedingungen entwickelten Normen enthalten weder Regeln, wie die unter-schiedlichen Verfahrensweisen der Beurteilung von Gebäuden zu Bewertungsverfahren weiterentwickelt werden können, noch schreiben sie Grenzwerte, Klassen oder Richtwerte für die Bemessung der Qualität vor.
ANMERKUNG Bewertungsverfahren, Grenzwerte, Klassen oder Richtwerte können in den umweltbezogenen, sozialen und ökonomischen Qualitätsanforderungen des Lastenheftes des Auftraggebers, der gesetzlichen Vorgaben im Bauwesen, nationaler Normen, nationaler Verfahrensregeln, von Zertifizierungssystemen usw. vorgeschrieben werden.
Die Regeln zur Bewertung der umweltbezogenen, sozialen und ökonomischen Aspekte von Organisationen sind in diesem Rahmenwerk nicht enthalten. Die Folgen von Entscheidungen oder Maßnahmen, die die umweltbezogene, soziale und ökonomische Qualität des bewerteten Objektes beeinflussen, werden jedoch berücksichtigt.
Contribution des ouvrages de construction au développement durable - Cadre pour l'évaluation des performances intégrées au bâtiment - Partie 1: Cadre général
La présente Norme européenne présente les principes généraux et les exigences, sous la forme d’une série de normes, pour l’évaluation des bâtiments en termes de performances environnementales, sociales et économiques, en prenant en compte leurs caractéristiques techniques et fonctionnelles. L'évaluation permettra de quantifier la contribution au développement et à la construction durables des ouvrages concernés.
Le cadre méthodologique s’applique à tous les types de bâtiments et concerne l’évaluation des performances environnementales, sociales et économiques des bâtiments neufs tout au long de leur cycle de vie, et celles des bâtiments existants pour leur durée de vie restante et leur phase de fin de vie.
Les normes élaborées dans ce cadre méthodologique ne définissent pas de règles concernant la façon dont les différents programmes d'évaluation peuvent fournir des méthodes d'attribution de valeur. Elles ne prescrivent pas non plus de niveaux, classes ou références comparatives pour situer les performances.
NOTE Des méthodes d'attribution de valeur, 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 du bâtiment, des normes nationales, des codes de bonnes pratiques nationaux, des programmes de certification, etc.
Les règles de l’évaluation des aspects environnementaux, sociaux ou économiques des organisations 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.
Trajnostnost gradbenih objektov - Ocenjevanje trajnostnosti stavb - 1. del: Splošni okvir
Ta evropski standard v seriji standardov zagotavlja splošna načela in zahteve za ocenjevanje zgradb v smislu okoljskega, družbenega in ekonomskega delovanja, z upoštevanjem tehničnih značilnosti in funkcionalnosti zgradbe. Ocena količinsko ovrednoti prispevek ocenjevanih gradbenih del k trajnostni gradnji in trajnostnemu razvoju. Okvir velja za vse vrste zgradb in je pomemben za ocenjevanje okoljskega, družbenega in ekonomskega delovanja novih zgradb v njihovem celotnem življenjskem krogu in obstoječih zgradb v njihovem preostalem času delovanja in na koncu življenjske dobe. Standardi, oblikovani znotraj tega okvira, ne postavljajo pravil o tem, kako lahko različne sheme ocenjevanja zgradb omogočajo metode vrednotenja. Prav tako ne predpisujejo ravni, razredov ali meril za merjenje delovanja.
OPOMBA: Metode vrednotenja, ravni, razrede ali merila so lahko predpisani v zahtevah za okoljsko, družbeno in ekonomsko delovanje v naročnikovem opisu, gradbenih predpisih, nacionalnih standardih, nacionalnih kodeksih ravnanja, certifikacijskih shemah, itd. Upoštevati je treba tudi posledice odločitev ali dejanj, ki vplivajo na okoljsko, družbeno in ekonomsko delovanje ocenjevanega objekta.

EN 15643-1:2010 (E) 4 Introduction This European Standard is part of a series written by CEN/TC 350 that provides a system for the sustainability assessment of buildings using a life cycle approach. The sustainability assessment quantifies impacts and aspects for the environmental, social and economic performance of buildings using quantitative and qualitative indicators, both of which are measured without value judgements. The purpose of this series of European 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 European Standards will allow the sustainability assessment, i.e. the assessment of environmental, social and economic performance of a building, to be made concurrently and on an equal footing, on the basis of the same technical characteristics and functionality of the object of assessment. The sustainability assessment of buildings uses different types of information. The results of a sustainability assessment of the building provide values for the different types of indicators, and information on the scenarios and building life cycle stages included in the assessment. In carrying out assessments, scenarios and a functional equivalent are determined at the building level. Assessment at the building level means that the descriptive model of the building 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 for the whole building, for parts of the building which can be used separately or for elements of the building. 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 the regulations, may be declared and communicated. Figure 1 shows how the functional equivalent and the technical and functional characteristics that deviate from those required, either by the client's brief or through regulations, are to be declared and communicated with the results of the assessment.

Figure 1 The concept of sustainability assessment of buildings NOTE 1 The outer box with the dotted line represents the area to be standardised by CEN/TC 350. In concept, the integrated building performance incorporates environmental, social and economic performance as well the technical and functional performance, and these are intrinsically related to each other, as illustrated in Figure 2. 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 prerequisite for an assessment of sustainability performance of buildings, and is therefore taken into account. 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 sketch plan stage in order to provide a broad estimate of the environmental performance, social performance and economic performance. As the project evolves, the assessment may 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.

Figure 2 The work programme of CEN/TC 350 NOTE 2 The darkened boxes represent the work programme of CEN/TC 350. This document, EN 15643-1, is the first part of the framework standards for sustainability assessment of buildings. The purpose of EN 15643-1 is to provide a framework with principles, requirements and guidelines for the sustainability assessment of buildings. It focuses on the general principles and requirements for the assessment of the environmental performance, social performance and economic performance of a building as described at the "framework level" in Figure 2. The first revision of this general framework standard, EN 15643-1, will combine all four parts of the framework of this series of standards into one framework standard. This will ensure simultaneous revision of the interlinked parts of the frameworks within the series of standards. In the future, the assessment methodologies within this series of standards may be part of an overall assessment of integrated building performance. The assessment methodologies may also be extended to an assessment of the neighbourhoods and wider built environment. SIST EN 15643-1:2010
EN 15643-1:2010 (E) 7 1 Scope This European Standard provides the general principles and requirements, expressed through a series of standards, for the assessment of buildings in terms of environmental, social and economic performance taking into account technical characteristics and functionality of a building. The assessment will quantify the contribution of the assessed construction works to sustainable construction and sustainable development. The framework applies to all types of buildings and it is relevant for the assessment of the environmental, social and economic performance of new buildings over their entire life cycle, and of existing buildings over their remaining service life and end of life stage. The standards developed under this framework do not set the rules for how the different building assessment schemes may provide valuation methods. Nor do they prescribe levels, classes or benchmarks for measuring performance. NOTE Valuation methods, levels, classes or benchmarks may be prescribed in the requirements for environmental, social and economic performance in the client’s brief, building regulations, national standards, national codes of practice, certification schemes, etc. The rules for assessment of environmental, social or economic aspects of organizations 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. 2 Normative references The following referenced documents are indispensable for the application of this document.

Introduction
This European Standard forms part of a suite of the European Standards, written by CEN/TC 350, that provide
a system for the sustainability assessment of buildings using a life cycle approach and quantitative indicators
for the environmental performance, social performance and economic performance of buildings.
The purpose of this EN is to provide a framework with principles, requirements and guidelines for the
sustainability assessment of construction works. The purpose of the suite of standards within this framework is
to enable comparability of the results of assessments.
In carrying out assessments, only at the building level it is possible to provide necessary scenarios and a
functional equivalent for the building. Assessment at the building level means that the descriptive model of the
building with the major technical and functional requirements has been defined (as represented in the client's
brief and regulatory requirements and are the same for each part of the assessment illustrated in the Figure 1.
This suite of standards will allow the sustainability assessment, i.e. the assessment of environmental, social
and economic performance of a building to be made concurrently and on an equal footing, on the basis of the
same technical characteristics and functionality of the object of assessment.
Although, the evaluation of technical and functional performance is beyond the scope of this suite of
standards, the technical performance and functional performance are, considered within this framework by
reference to the functional. The functional equivalent takes into account the technical and functional
requirements and forms the basis for comparisons of the results of the assessment.
Figure 1, shows how the functional equivalent, and any deviation in the technical and functional performance
from that required either by the client's brief or through regulation, are to be declared and communicated with
the results of the assessment. Demands for the environmental, social and economic performance defined in
the client’s brief, or in the regulations, are made available for communication.

Figure 1 – The outer box with the dotted line represents the area to be standardised by CEN/TC350
and the concept of sustainability assessment of buildings
Developing a framework for the sustainability assessment of buildings as a contribution to implementing
sustainability of construction works is a multi-step procedure.
The first revision of this framework standard will combine all four parts of the framework of this suite of
standards into one framework standard.
When describing the integrated building performance at the "concept level", the environmental, social and
economic performance are one part and the technical and functional performance are another; both parts are
intrinsically related to each other, as described in the Figure 2. This interrelationship is prerequisite for an
assessment of sustainability performance of buildings.

on the general principles and requirements for the assessment of the environmental performance, social
performance and economic performance of a building as described at the “framework level“ in the Figure 2.

1 Scope
This European Standard provides the general principles and requirements, expressed through a suite of
standards, for the sustainability assessment of buildings in terms of environmental performance, social
performance and economic performance taking into account technical characteristics and functionality of a
building.
The framework applies to all types of buildings, both new and existing, and it is relevant for the assessment of
the environmental, social and economic performance of new buildings over their entire life cycle, and of
existing buildings undergoing refurbishment, renewal or extension, to the end of their life.
NOTE 1 In the future, the assessment methodologies within this framework standard may be part of an overall
assessment of integrated building performance. The assessment methodologies may also be extended to an assessment
of the neighbourhoods and the built environment.
The 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, classes or benchmarks for
measuring performance.
NOTE 2 Valuation methods, levels, classes or benchmarks may be prescribed in the requirements for environmental,
social and economic performance in the client’s brief, building regulations, national standards, national codes of practice
etc.
The rules for assessment of environmental, social or economic aspects of organizations are not included
within this framework. However, their results, which impact the environmental, social and economic
performance of the object of assessment, are taken into account.
