Sustainability of construction works - Assessment of environmental performance of buildings - Requirements and guidance

Edition date: 2026-03-25
In Force
Available languages: English
Summary: This document specifies the calculation method, based on Life Cycle Assessment (LCA) and other quantified environmental information, to assess the environmental performance of a building and its site, during whole life cycle, based on a building life cycle model. It also establishes a system for the reporting and communication of the outcome of the assessment. The document gives: - the description of the object of assessment based on the functional equivalent; - the system boundary that applies at the building level; - calculation rules and procedure to be used to compile and assess the life cycle inventory and life cycle environmental impacts of buildings; - the list of indicators and procedures for the calculation of these indicators; - demand for information concerning building generated energy reporting; - the requirements for the data necessary for the calculation; - provides recommendations on how to assess aspects at the local environment level; and - the requirements for presentation of the results in reporting and communication. The approach to the assessment covers all stages of the building life cycle and is based on data obtained from Environmental Product Declarations (EPD) and their "information modules" (EN 15804:2012+A2:2019), generic data according to EN 15941 and other data and information necessary and relevant for carrying out the assessment. The assessment includes all building related construction products, processes and services, used over the life cycle of the building. The document is applicable to new, existing buildings and buildings undergoing refurbishment or any other kind of activity to extend its service life. Environmental impacts and aspects that are not related to the building are outside the scope of this standard. Methodologies for and approaches to the interpretation and the making of value judgments of the results of the assessment are outside the scope of this document. The document also provides the methodological basis and assessment rules to support the achievement of environment related macro-objectives in Europe and instruments such as the European reporting framework Level(s). NOTE More information on the European reporting framework Level(s)can be found at Level(s) (europa.eu). Informative Annexes B and C provide non-LCA information covering environmental aspects at the local environment level and additional information on end-of-life scenarios.

Le présent document fournit la méthode de calcul reposant sur l’analyse du cycle de vie (ACV) et d’autres informations environnementales quantifiées, qui permet d’évaluer la performance environnementale d’un bâtiment et de sa parcelle, tout au long du cycle de vie, en s’appuyant sur un modèle de cycle de vie du bâtiment. Il établit également un système pour élaborer le rapport et communiquer le résultat de cette évaluation. Le présent document fournit: — la description de l’objet de l’évaluation sur la base de l’équivalent fonctionnel; — la frontière du système qui s’applique au niveau du bâtiment; — les règles de calcul et les procédures à utiliser pour compiler et évaluer l’inventaire du cycle de vie et les impacts environnementaux du cycle de vie des bâtiments; — la liste des indicateurs et des procédures de calcul de ces indicateurs; — la demande d’informations concernant le reporting de l’énergie produite par le bâtiment; — les exigences relatives aux données nécessaires pour réaliser le calcul; — des recommandations sur la manière d’évaluer les aspects à l’échelle de l’environnement local; et — les exigences relatives à la présentation des résultats dans le cadre de la communication. La méthode d’évaluation couvre toutes les phases du cycle de vie d’un bâtiment et repose sur les données obtenues à partir des Déclarations Environnementales sur les Produits (DEP) et de leurs "modules d’informations" (EN 15804:2012+A2:2019), des données génériques conformément à l’EN 15941 et des autres données et informations nécessaires en rapport avec l’évaluation. L’évaluation comprend tous les produits de construction, les processus et les services en rapport avec le bâtiment, sur l’ensemble de son cycle de vie. Le document s’applique aux bâtiments neufs, existants et en cours de réhabilitation ou faisant l’objet de tout autre type d’activité visant à prolonger leur durée de vie. Les impacts et aspects environnementaux qui ne sont pas liés au bâtiment n’entrent pas dans le domaine d’application de la présente norme. Les méthodologies et les approches relatives à l’interprétation des résultats de l’évaluation et à la formulation de jugements de valeur sur ces résultats n’entrent pas dans le domaine d’application du présent document. Le présent document fournit également la base méthodologique et les règles d’évaluation pour soutenir la réalisation des macro-objectifs liés à l’environnement en Europe et des instruments tels que le cadre européen de reporting Level(s). NOTE Des informations plus détaillées sur le cadre européen de reporting Level(s) sont disponibles à l’adresse Level(s) (europa.eu). Les Annexes B et C, informatives, fournissent des informations hors ACV couvrant les aspects environnementaux à l’échelle de l’environnement local, ainsi que des informations additionnelles sur les scénarios de fin de vie.

Dieses Dokument legt ein auf der Ökobilanzierung (LCA, en: life cycle assessment) und quantitativen Umweltdaten basierendes Berechnungsverfahren zur Bewertung der umweltbezogenen Qualität eines Gebäudes und seines Standortes über die gesamte Lebensdauer auf Grundlage eines Gebäude- und eines Lebenszyklusmodells fest. Es legt außerdem ein System für die Darstellung und Kommunikation des Bewertungsergebnisses fest. Dieses Dokument enthält:  die Beschreibung des Bewertungsgegenstandes anhand des funktionalen Äquivalents;  die auf Gebäudeebene geltende Systemgrenze;  Bilanzierungsregeln und Verfahren zum Erstellen und Bewerten der Sachbilanz und der Umweltauswirkungen des Gebäudes während seines Lebenszyklus;  die Liste von Indikatoren und die Verfahren zur Berechnung dieser Indikatoren;  den Informationsbedarf hinsichtlich der Berichterstattung über die im Gebäude erzeugte Energie;  die Anforderungen an die für die Berechnung benötigten Daten;  Empfehlungen zur Bewertung von Aspekten von Emissionen in die lokale Umwelt; und  die Anforderungen an die Darstellung der Ergebnisse bei der Berichterstattung und Kommunikation. Der Bewertungsansatz deckt alle Phasen des Gebäudelebenszyklus ab und basiert auf den aus Umweltproduktdeklarationen (EPD, en: Environmental Product Declarations) und ihren „Informationsmodulen“ (EN 15804:2012+A2:2019) entnommenen Daten, generischen Daten nach EN 15941 und sonstigen Daten und Informationen, die für die Durchführung der Bewertung erforderlich und maßgebend sind. Die Bewertung schließt alle gebäudebezogenen Bauprodukte, -prozesse und -dienstleistungen ein, welche im Verlauf des Lebenszyklus des Gebäudes genutzt werden. Das Dokument ist auf neue und bestehende Gebäude und auf Gebäude anwendbar, die Modernisierungs- oder sonstigen Aktivitäten zur Verlängerung ihrer Nutzungsdauer unterzogen werden. Umweltauswirkungen und -aspekte, die sich nicht auf das Gebäude beziehen, sind nicht Gegenstand dieses Dokuments. Verfahren und Ansätze zur Auswertung und Einordnung der Bewertungsergebnisse sind nicht Gegenstand dieses Dokuments. Das Dokument enthält außerdem die methodische Grundlage und die Bewertungsregeln, um das Erreichen von umweltbezogenen Makrozielen in Europa und Instrumente wie Level(s), dem europäischen Rahmen zur. Berichterstattung, zu unterstützen. ANMERKUNG Weitere Informationen zum Europäischen Rahmen zur Berichterstattung Level(s) stehen unter Level(s) (europa.eu) zur Verfügung. Der informative Anhang B und der informative Anhang C enthalten nicht zur Ökobilanz gehörende Informationen, die Umweltaspekte in die lokale Umwelt abdecken, und Zusatzinformationen zu Szenarien für das Ende der Nutzung.
