Sustainability of construction works - Data quality for environmental assessment of products and construction work - Selection and use of data
This document supports the data quality assessment and selection of data for product-level Environmental Product Declarations (EPD) according to the core product category rules of EN 15804 and for the environmental performance assessment of buildings according to prEN 15978 1 in a consistent way. It can also be used to assess and select data for the environmental assessment of civil engineering works according to EN 17472.
It defines data quality requirements with respect to temporal, technological and geographical representativeness for the data used to calculate the Life Cycle Assessment (LCA) based indicator results of the EPD and for construction works when applying EPD, life cycle inventory data or other LCA based information, and generates a hierarchy to support the selection of the most appropriate data with regard to data quality. It also addresses the reporting of data quality at product and building level.
Nachhaltigkeit von Bauwerken - Datenqualität für die Erfassung der Umweltqualität von Produkten und Bauwerken - Auswahl und Anwendung von Daten
Dieses Dokument legt die einheitliche Bewertung der Datenqualität und Datenauswahl für Umweltproduktdeklarationen (EPD) entsprechend den Produktkategorie-Grundregeln nach EN 15804 und für die Bewertung der umweltbezogenen Qualität von Gebäuden nach EN 15978 fest. Es kann ebenfalls für die Bewertung und Auswahl von Daten für die Umweltbewertung von Ingenieurbauwerken nach EN 17472 angewendet werden.
Es legt Anforderungen an die Datenqualität hinsichtlich der zeitlichen, technologischen und geografischen Repräsentativität der Daten fest, welche für die Berechnung der auf der Ökobilanz (LCA, en: life cycle assessment) beruhenden Indikatorwerte der EPD und für Bauwerke bei Anwendung einer EPD, von Sachbilanz-Daten oder anderen auf der Ökobilanz basierenden Angaben verwendet werden und gibt eine Anleitung für die Erstellung einer Hierarchie, um die Auswahl der hinsichtlich der Datenqualität am besten geeigneten Daten zu unterstützen. Es behandelt außerdem die Berichterstattung über die Datenqualität auf der Produkt- und Gebäudeebene.
Contribution des ouvrages de construction au développement durable - Qualité des données pour l'évaluation environnementale des produits et des ouvrages de construction - Sélection et utilisation des données
Le présent document aide à évaluer la qualité des données et à sélectionner les données, de manière cohérente, pour les Déclarations environnementales de produits (DEP) au niveau des produits, conformément aux règles propres à la catégorie de produits de l'EN 15804, et pour l'évaluation de la performance environnementale des bâtiments, conformément au projet de norme prEN 15978 1. Il peut également être utilisé pour évaluer et sélectionner les données dans le cadre de l'évaluation environnementale des ouvrages de génie civil, conformément à l'EN 17472.
Le présent document définit les exigences relatives à la qualité des données selon leur représentativité temporelle, technologique et géographique en ce qui concerne les données servant à calculer les résultats des indicateurs ACV de la DEP et des ouvrages de construction utilisant des DEP, données d'inventaire du cycle de vie ou autres informations basées sur l'analyse du cycle de vie (ACV) et génère une hiérarchie visant à faciliter la sélection des données les plus appropriées en matière de qualité des données. Il aborde également la question de l'établissement des rapports sur la qualité des données, au niveau des produits et des bâtiments.
Trajnostnost gradbenih objektov - Kakovost podatkov za okoljsko oceno proizvodov in gradbenih del - Izbor in uporaba podatkov
Ta dokument na dosleden način podpira oceno kakovosti podatkov in izbor podatkov za okoljske deklaracije o proizvodih (EPD) na ravni proizvoda v skladu z osnovnimi pravili za kategorije proizvodov iz standarda EN 15804 ter za oceno okoljskih učinkov stavb v skladu s standardom prEN 15978-1. Uporabiti ga je mogoče tudi za presojo in izbor podatkov za okoljsko oceno gradbenih inženirskih objektov.
Določa zahteve glede kakovosti podatkov v zvezi s časovno, tehnološko in geografsko reprezentativnostjo za podatke, ki se uporabljajo za izračun rezultatov kazalnikov okoljske deklaracije o proizvodih, ki temeljijo na oceni življenjskega cikla (LCA), in za gradbene objekte pri uporabi okoljske deklaracije o proizvodih, podatkov o popisu življenjskega cikla ali drugih informacij, ki temeljijo na oceni življenjskega cikla, ter ustvarja hierarhijo za podporo izbora najprimernejših podatkov glede na njihovo kakovost. Obravnava tudi poročanje o kakovosti podatkov na ravni proizvoda in stavbe.
