(Main)Low-voltage electrical installations - Part 8-1: Energy efficiency
Low-voltage electrical installations - Part 8-1: Energy efficiency
IEC 60364-8-1:2014 provides additional requirements, measures and recommendations for the design, erection and verification of all types of low-voltage electrical installation including local production and storage of energy for optimizing the overall efficient use of electricity. It introduces requirements and recommendations for the design of an electrical installation within the framework of an energy efficiency management approach in order to get the best permanent functionally equivalent service for the lowest electrical energy consumption and the most acceptable energy availability and economic balance. These requirements and recommendations apply, within the scope of the IEC 60364 series, for new installations and modification of existing installations. This standard is applicable to the electrical installation of a building or system and does not apply to products. The energy efficiency of these products and their operational requirements are covered by the relevant product standards. This standard does not specifically address building automation systems.
Errichten von Niederspannungsanlagen - Teil 8-1: Energieeffizienz
Installations électriques basse tension - Partie 8-1: Efficacité énergétique
L'IEC 60364-8-1:2014 fournit des exigences, des mesures et des recommandations supplémentaires pour la conception, la mise en oeuvre et la vérification de tous types d'installations électriques basse tension comportant la production locale et le stockage local de l'énergie pour optimiser l'utilisation efficace globale de l'électricité. Elle présente les exigences et les recommandations pour la conception d'une installation électrique dans le cadre d'une approche de gestion de l'efficacité énergétique afin d'obtenir la fonctionnalité équivalente au meilleur service permanent pour la consommation d'énergie électrique la plus faible, la disponibilité de l'énergie et l'équilibre économique les plus acceptables. Ces exigences et recommandations s'appliquent, dans le domaine d'application de la série IEC 60364, pour les installations neuves et la modification d'installations existantes. La présente norme est applicable à l'installation électrique d'un bâtiment ou d'un système et ne s'applique pas aux produits. L'efficacité énergétique de ces produits et leurs exigences opérationnelles sont couvertes par les normes de produits concernées. La présente norme ne traite pas spécifiquement des systèmes d'automatisation de bâtiments.
Nizkonapetostne električne inštalacije - 8-1. del: Energijska učinkovitost
Ta del standarda IEC 60364 določa dodatne zahteve, ukrepe in priporočila za zasnovo, postavitev in preverjanje vseh vrst nizkonapetostnih električnih inštalacij, vključno z lokalno proizvodnjo in shranjevanjem energije za optimizacijo celotne učinkovite uporabe električne energije. Uvaja zahteve in priporočila za zasnovo električnih inštalacij v okviru pristopa upravljanja energijske učinkovitosti, da bi dobili najboljšo stalno funkcionalno enakovredno storitev za najnižjo porabo električne energije in najbolj sprejemljivo razpoložljivost energije ter gospodarsko ravnotežje.
Te zahteve in priporočila veljajo, v okviru skupine standardov IEC 60364, za nove inštalacije in spremembe obstoječih inštalacij. Ta standard velja za električno inštalacijo zgradbe ali sistema in ne velja za izdelke. Energijsko učinkovitost teh izdelkov in njihovih obratovalnih zahtev določajo ustrezni standardi za izdelke. Ta standard se ne nanaša neposredno na gradnjo sistemov za avtomatizacijo.
