Energy performance of buildings - Contribution of building automation, controls and building management - Part 1: General framework and procedures (ISO 52120-1:2021, Corrected version 2022-09)

This document specifies:
—    a structured list of control, building automation and technical building management functions which contribute to the energy performance of buildings; functions have been categorized and structured according to building disciplines and building automation and control (BAC);
—    a method to define minimum requirements or any specification regarding the control, building automation and technical building management functions contributing to energy efficiency of a building to be implemented in building of different complexities;
—    a factor-based method to get a first estimation of the effect of these functions on typical buildings types and use profiles;
—    detailed methods to assess the effect of these functions on a given building.

Energieeffizienz von Gebäuden - Einfluss von Gebäudeautomation und Gebäudemanagement - Teil 1: Allgemeiner Rahmen und Verfahren (ISO 52120-1:2021, korrigierte Fassung 2022-09)

Performance énergétique des bâtiments - Contribution de l’automatisation, de la régulation et de la gestion technique des bâtiments - Partie 1: Cadre général et procédures (ISO 52120-1:2021, Version corrigée 2022-09)

Ce document spécifie:
—    une liste structurée des fonctions de régulation, d’automatisation et de gestion technique du bâtiment qui contribuent à la performance énergétique des bâtiments; les fonctions ont été classées en catégories et structurées conformément aux disciplines du bâtiment et de ce qui s’appelle l’automatisation et la régulation du bâtiment (BAC, building automation and control);
—    une méthode pour définir les exigences minimales ou toute spécification concernant les fonctions de régulation, d’automatisation et de gestion technique du bâtiment à mettre en œuvre dans des bâtiments de différentes complexités et contribuant à leur efficacité énergétique;
—    une méthode basée sur des facteurs pour obtenir une première estimation de l’effet de ces fonctions sur les types de bâtiments et les profils d’utilisation courants;
—    des méthodes détaillées pour estimer l’effet de ces fonctions sur un bâtiment donné.

Energijske lastnosti stavb - Vpliv avtomatizacije, regulacije in upravljanja stavb - 1. del: Splošni okvir in postopki (ISO 52120-1:2021, popravljena različica 2022-09)

Ta evropski standard določa:
–   strukturiran seznam funkcij za nadzor, avtomatizacijo in tehnično upravljanje stavb, ki prispevajo k energijski učinkovitosti stavb. Funkcije so bile razvrščene v kategorije in strukturirane glede na discipline stavbeništva in t. i. sistem za avtomatizacijo in nadzor stavb (BAC);
–   metodo za opredelitev minimalnih zahtev oziroma specifikacije v zvezi s funkcijami za nadzor, avtomatizacijo in tehnično upravljanje stavb, ki prispevajo k energijski učinkovitosti stavb in jih je treba uvesti v različno kompleksnih stavbah;
–   metodo, ki temelji na faktorju, za prvo oceno učinka teh funkcij na običajne vrste stavb in profile uporabe;
–   natančne metode za oceno učinka teh funkcij na določeno stavbo.
Preglednica 1 prikazuje relativno mesto tega standarda znotraj skupine standardov EPB v kontekstu modularne strukture, kot je opredeljeno v standardu EN ISO 52000-1.
OPOMBA 1:   V standardu CEN ISO/TR 52000-2 je za vsak modul mogoče najti enako preglednico s številkami ustreznih standardov EPB in spremnimi tehničnimi poročili, ki so objavljeni ali v pripravi.
OPOMBA 2:   Moduli predstavljajo standarde EPB, čeprav lahko en standard EPB zajema več kot en modul, en modul pa je lahko zajet v več kot enem standardu EPB (na primer poenostavljena metoda in podrobna metoda).
