<\/p>\n\n\n\n

La conformit\u00e9 aux normes GACS devient une priorit\u00e9 urgente pour les propri\u00e9taires et les exploitants de grands b\u00e2timents non r\u00e9sidentiels dans le Benelux. Et la pression va au-del\u00e0 de l’installation d’un syst\u00e8me de contr\u00f4le. De nombreuses organisations essaient maintenant de comprendre ce dont elles ont besoin en plus pour rendre la performance \u00e9nerg\u00e9tique visible, mesurable et plus facile \u00e0 am\u00e9liorer au fil du temps. <\/p>\n\n\n\n

Un syst\u00e8me d’automatisation et de contr\u00f4le des b\u00e2timents<\/strong> (aussi BACS en anglais ou GACS au Benelux) peut contr\u00f4ler activement des syst\u00e8mes tels que le chauffage, la ventilation, la climatisation et l’\u00e9clairage. Mais le contr\u00f4le seul ne permet pas de savoir o\u00f9 l’\u00e9nergie est gaspill\u00e9e, quels sont les sites les moins performants ou comment les progr\u00e8s doivent \u00eatre suivis dans l’ensemble d’un portefeuille. C’est pourquoi de nombreuses organisations auront besoin de plus d’un syst\u00e8me en place.<\/p>\n\n\n\n

Pour les propri\u00e9taires et les exploitants de b\u00e2timents, il ne s’agit donc pas seulement d’une question de conformit\u00e9. Il s’agit \u00e9galement d’une question de performance. Car une fois l’automatisation obligatoire, le prochain d\u00e9fi consiste \u00e0 transformer les donn\u00e9es du b\u00e2timent en actions, en connaissances et en am\u00e9liorations mesurables dans l’ensemble du portefeuille. <\/p>\n\n\n\n

Ce que la conformit\u00e9 au d\u00e9cret BACS signifie pour les propri\u00e9taires de b\u00e2timents<\/strong><\/h2>\n\n\n\n

Sur le papier, l’automatisation des b\u00e2timents semble simple. Installez les bonnes capacit\u00e9s de contr\u00f4le. Connectez les syst\u00e8mes techniques. R\u00e9pondez aux exigences. En r\u00e9alit\u00e9, le d\u00e9fi est plus vaste. <\/p>\n\n\n\n

La plupart des organisations ne g\u00e8rent pas un b\u00e2timent de mani\u00e8re isol\u00e9e. Elles ont affaire \u00e0 plusieurs sites, \u00e0 des donn\u00e9es fragment\u00e9es, \u00e0 des syst\u00e8mes diff\u00e9rents et \u00e0 une pression croissante pour r\u00e9duire les co\u00fbts et am\u00e9liorer les r\u00e9sultats en mati\u00e8re de d\u00e9veloppement durable. Dans cet environnement, le contr\u00f4le est essentiel, mais il ne repr\u00e9sente qu’une partie du tableau op\u00e9rationnel. <\/p>\n\n\n\n

En effet, les \u00e9quipes immobili\u00e8res ont besoin de r\u00e9ponses claires sur la performance et l’efficacit\u00e9 des b\u00e2timents, en plus du contr\u00f4le. Quels sont les b\u00e2timents qui s’\u00e9cartent de leur objectif ? O\u00f9 la consommation anormale appara\u00eet-elle ? Quelles actions permettront de r\u00e9aliser les \u00e9conomies les plus importantes ? Et comment les \u00e9quipes peuvent-elles montrer les progr\u00e8s r\u00e9alis\u00e9s d’une mani\u00e8re coh\u00e9rente, v\u00e9rifiable et utilisable pour l’ensemble d’un portefeuille ? <\/p>\n\n\n\n

Pourquoi un seul syst\u00e8me n’est pas suffisant pour assurer la conformit\u00e9 au GACS<\/strong> <\/h2>\n\n\n\n

Il s’agit l\u00e0 d’un point essentiel. La conformit\u00e9 au GACS ne doit pas \u00eatre consid\u00e9r\u00e9e comme une d\u00e9cision portant sur un seul syst\u00e8me<\/strong>. Il est pr\u00e9f\u00e9rable de la consid\u00e9rer comme un ensemble de capacit\u00e9s. <\/p>\n\n\n\n

Une couche assure le contr\u00f4le. Une autre couche aide les organisations \u00e0 comprendre la consommation d’\u00e9nergie, \u00e0 comparer les performances, \u00e0 mod\u00e9liser des sc\u00e9narios et \u00e0 produire des rapports qui facilitent la prise de d\u00e9cision et l’am\u00e9lioration continue. Dans les grands portefeuilles, cette deuxi\u00e8me couche devient particuli\u00e8rement importante, car l’analyse manuelle ne s’adapte pas bien, et les donn\u00e9es fragment\u00e9es rendent difficile l’obtention de r\u00e9sultats fiables. <\/p>\n\n\n\n

C’est \u00e9galement la raison pour laquelle les discussions sur le march\u00e9 \u00e9voluent. Les acheteurs ne se contentent pas de demander si leurs b\u00e2timents peuvent \u00eatre contr\u00f4l\u00e9s. Ils se demandent s’ils peuvent faire confiance aux donn\u00e9es, identifier plus rapidement les gaspillages et transformer les informations sur l’\u00e9nergie en actions reproductibles sur l’ensemble des sites. <\/p>\n\n\n\n

Comment Spacewell Energy soutient la conformit\u00e9 au BACS<\/strong><\/h2>\n\n\n\n

C’est l\u00e0 que Spacewell Energy a un r\u00f4le clair \u00e0 jouer. Il s’agit d’un syst\u00e8me de gestion de l’\u00e9nergie \u00e0 l’\u00e9chelle du portefeuille con\u00e7u pour aider les organisations \u00e0 comprendre, mod\u00e9liser et optimiser la fa\u00e7on dont l’\u00e9nergie est consomm\u00e9e, produite, stock\u00e9e et transform\u00e9e dans l’ensemble des b\u00e2timents. <\/p>\n\n\n\n

Il est important de noter que Spacewell Energy n’est pas un BACS. Il n’effectue pas de contr\u00f4le actif des \u00e9quipements ni d’automatisation en temps r\u00e9el de la Gestion Technique du B\u00e2timent (GTB). Au lieu de cela, il compl\u00e8te le contr\u00f4le en ajoutant l’agr\u00e9gation et l’analyse comparative au niveau du portefeuille, l’analyse de l’\u00e9nergie, des co\u00fbts, des \u00e9conomies et du CO\u2082, la d\u00e9tection des anomalies, des tableaux de bord \u00e9volutifs et des mod\u00e8les de rapports, ainsi que des int\u00e9grations avec les compteurs, les plateformes de GTB<\/a>, les GRD et les syst\u00e8mes IoT.<\/p>\n\n\n\n

Elle est donc particuli\u00e8rement pertinente pour les organisations qui se posent la question logique suivante apr\u00e8s la conformit\u00e9 : comment surveiller les r\u00e9sultats, identifier les inefficacit\u00e9s et continuer \u00e0 s’am\u00e9liorer au fil du temps ? Spacewell Energy est con\u00e7u pour r\u00e9pondre \u00e0 ces questions gr\u00e2ce \u00e0 des informations fiables sur l’\u00e9nergie, des r\u00e9sultats v\u00e9rifiables et des analyses reproductibles \u00e0 grande \u00e9chelle. <\/p>\n\n\n\n

Le message sur le produit met \u00e9galement l’accent sur une valeur mesurable. Spacewell Energy a obtenu une r\u00e9duction de 5 \u00e0 20 % de la consommation d’\u00e9nergie gr\u00e2ce \u00e0 la visibilit\u00e9, \u00e0 l’analyse comparative et \u00e0 l’\u00e9tablissement de priorit\u00e9s, ainsi qu’\u00e0 une d\u00e9tection plus rapide des anomalies, \u00e0 une r\u00e9duction du travail manuel d’\u00e9tablissement de rapports et \u00e0 une meilleure v\u00e9rifiabilit\u00e9 des donn\u00e9es relatives aux co\u00fbts et aux \u00e9missions de CO\u2082, bien que les r\u00e9sultats varient en fonction de la maturit\u00e9 du portefeuille et de la qualit\u00e9 des donn\u00e9es. <\/p>\n\n\n\n

Transformer la conformit\u00e9 au BACS en une opportunit\u00e9 de performance<\/strong><\/h2>\n\n\n\n

C’est pourquoi la conformit\u00e9 aux normes GACS ne doit pas \u00eatre consid\u00e9r\u00e9e uniquement comme une charge r\u00e9glementaire. Pour de nombreux propri\u00e9taires de b\u00e2timents, c’est aussi l’occasion de moderniser la fa\u00e7on dont la performance \u00e9nerg\u00e9tique est g\u00e9r\u00e9e dans l’ensemble du portefeuille. <\/p>\n\n\n\n

Les organisations qui en b\u00e9n\u00e9ficieront le plus seront celles qui consid\u00e8rent la conformit\u00e9 comme le point de d\u00e9part, et non comme la ligne d’arriv\u00e9e. Le contr\u00f4le est important. Mais il en va de m\u00eame pour la perspicacit\u00e9, les preuves et la capacit\u00e9 \u00e0 \u00e9tablir des priorit\u00e9s d’action en toute confiance <\/strong>.<\/p>\n\n\n\n

Dans ce contexte plus large, Spacewell Energy n’est pas le syst\u00e8me de contr\u00f4le lui-m\u00eame. C’est la couche d’intelligence \u00e9nerg\u00e9tique qui aide les organisations \u00e0 transformer l’automatisation des b\u00e2timents en une am\u00e9lioration mesurable des performances.
