The new European Energy Performance of Buildings Directive, EPBD 2024, marks a profound change in the way automation is understood. It is no longer just about installing efficient equipment. It is about the building being able to monitor, control, optimize and demonstrate how it consumes energy.
The EPBD 2024 was published in May 2024 and Member States must adapt their regulations by May 29, 2026. In addition, it introduces obligations related to automation and control systems in buildings, especially in non-residential buildings with technical installations above 70 kW.
This is where BACS, Building Automation & Control Systems, evaluable according to EN ISO 52120-1, come in. This standard classifies the functional level of building automation into four classes: D, C, B and A. Class C represents minimum compliance, while Classes B and A are geared toward advanced automation, with demand-based control, continuous monitoring, interoperability and energy optimization.
