General requirements for Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS) - Part 12-2: Smart grid - Application specification - Interface and framework for customer - Interface between the Home / Building CEM and Resource manager(s) - Data model and messaging

This document specifies the fundamental aspects of semantic interoperability for the S2 interface and the related data exchange between a CEM and the Resource Managers within the premises. It provides a technology independent set of data models and interaction patterns in order to enable applications for Energy Management within the premises. This document does not include: — mappings to concrete data representations (XML, JSON and similar); — mappings to application protocols for the message passing; — security related aspects.

Allgemeine Anforderungen an die Elektrische Systemtechnik für Heim und Gebäude (ESHG) und an Systeme der Gebäudeautomation (GA) – Teil 12-2: Smart grid – Anwendungsspezifikation – Schnittstelle und Modell für Anwender – Schnittstelle zwischen dem Heim-/Gebäude CEM und den Ressourcenmanagern – Datenmodell und Informationsaustausch

Exigences générales relatives aux systèmes électroniques pour les foyers domestiques et les bâtiments (HBES) et aux systèmes de gestion technique du bâtiment (SGTB) - Partie 12-2: Réseau intelligent - Spécification d'application - Interface et cadre pour le client - Interface entre le gestionnaire d'énergie pour le client (CEM, Customer Energy Manager) et le gestionnaire de ressources pour foyers domestiques/bâtiments - Modèle de données et échange de messages

Le présent document spécifie les aspects fondamentaux de l'interopérabilité sémantique de l'interface S2 et l'échange de données connexe entre un CEM et les gestionnaires de ressources à l'intérieur des locaux. Elle fournit un ensemble de modèles de données et de modèles d'interaction indépendant de la technologie afin de prévoir des applications de gestion de l'énergie à l'intérieur des locaux. Le présent document n'inclut pas: — les mappings vers les représentations de données concrètes (XML, JSON et apparentés); — les mappings vers des protocoles d'application pour l'envoi de messages; — les aspects relatifs à la sécurité.

Splošne zahteve za stanovanjske in stavbne elektronske sisteme (HBES) in sisteme za avtomatizacijo in krmiljenje stavb (BACS) - 12-2. del: Pametno omrežje - Aplikacijske specifikacije - Vmesnik in okvir za odjemalca - Vmesnik med upravljalcem stanovanjskih in stavbnih virov (CEM) - Podatkovni model in izmenjava podatkov

Ta dokument določa temeljne vidike semantične interoperabilnosti za vmesnik S2 in s tem povezane izmenjave podatkov med CEM in upravljavci virov v prostorih. Zagotavlja tehnološko neodvisen nabor podatkovnih modelov in vzorcev interakcije, ki v prostorih omogočajo aplikacije za upravljanje z energijo. Ta dokument ne vključuje:
–   preslikav v konkretne predstavitve podatkov (XML, JSON in podobno);
–   preslikav v aplikacijske protokole za posredovanje sporočil;
–   vidikov, povezanih z varnostjo.
