eu.bac has published guidelines to support Member States in transposing the revised EPBD, outlining key provisions on building automation, indoor environmental quality and technical building systems.
eu.bac has released guidelines to assist Member States in transposing Directive (EU) 2024/1275 on the energy performance of buildings. The document provides an industry perspective on the directive’s provisions and explains how smart building technologies can support national implementation.
The guidelines outline the main requirements introduced by the revised EPBD, including mandatory Building Automation and Control Systems (BACS) for large non‑residential buildings, the integration of hydronic balancing and self‑regulating devices, and new obligations related to indoor environmental quality. They also describe the forthcoming Union scheme for the Smart Readiness Indicator.
Further sections address data exchange, minimum energy performance standards, and exemptions from inspections for buildings equipped with compliant BACS. The document highlights the role of EN ISO 52120‑1 in calculating energy performance and explains how BACS functionalities contribute to monitoring, optimisation, and interoperability across technical building systems.
The publication also discusses feasibility considerations, compliance pathways, and the need for harmonised national approaches. It provides practical context for definitions such as technical building systems, indoor environmental quality, and air‑conditioning systems, linking them to the directive’s operational requirements.
