Directive (EU) 2024/1275, commonly referred to as EPBD 2024 or the recast EPBD, represents the most significant revision to European building energy legislation in over a decade. According to EUR-Lex, the text was published in the Official Journal of the EU on 8 May 2024 and entered into force on 28 May 2024, repealing and replacing the previous versions of the EPBD (Directive 2010/31/EU and its 2018 amendments). The central objective is to achieve a fully decarbonised EU building stock before 2050, articulated through concrete obligations on energy performance certification, renovation passports, smart readiness indicators, solar infrastructure, and life cycle assessment. According to the European Commission Directorate for Energy, Member States that fail to complete transposition by the 29 May 2026 deadline are exposed to infringement proceedings. | The scope of EPBD 2024 extends across all EU Member States and affects a broad range of stakeholders, including property owners, developers, energy certifiers, and asset managers, for both existing buildings and new construction. In Spain, for example, the directive must be integrated with existing instruments such as the Codigo Tecnico de la Edificacion (CTE), the Reglamento de Instalaciones Termicas en los Edificios (RITE), and the royal decrees governing energy certification. According to MITECO, Spain's institutional energy efficiency platform confirms that some measures were already aligned with existing national regulation, whilst others, particularly those relating to renovation passports and life cycle analysis, require additional regulatory development. According to BUILD UP, the European Commission's platform for building energy efficiency, Spain had reached approximately 60 per cent adaptation around the May 2026 transposition deadline, meaning a significant portion of the technical and administrative obligations still required specific normative development or updating of existing national instruments. | The first major technical obligation concerns energy performance certificates (EPCs). According to BUILD UP, from 29 May 2026 onwards all EPCs must use the mandatory A-to-G scale and the standardised template defined in Annex V of the directive. This harmonised format has two primary objectives: to facilitate comparability between real estate assets across the EU, and to provide more actionable information on recommended improvement measures. The directive adds requirements beyond those in existing national frameworks, including information on the global warming potential of embodied carbon, the smart readiness indicator (SRI) reflecting a building's capacity to interact with smart grids, and integration with the renovation passport. These elements require updates to inspection, calculation, and registration procedures managed by regional authorities across Member States. For asset-intensive typologies such as healthcare facilities and educational estates, where buildings are frequently large energy consumers with complex HVAC systems, accurate modelling of the updated EPC indicators is critical to meeting deadlines and avoiding administrative penalties. | The renovation passport is one of the most substantive innovations introduced by EPBD 2024. According to MITECO, the directive requires Member States to establish a renovation passport scheme based on Annex VIII of the directive, with a deadline of 29 May 2026. A renovation passport is a personalised document describing a staged deep renovation roadmap for a specific building, with the objective of reaching the highest possible energy performance level, ideally nearly zero-energy building (NZEB) standard or above. Unlike a conventional EPC, which captures the current energy state of a building, the renovation passport is a structured plan of sequential interventions, each with estimated energy savings, approximate costs, and temporal priority. Its technical value lies in enabling phased investment planning, minimising the risk of stranded assets, and maximising access to public funding mechanisms such as the EU Recovery and Resilience Facility. From a methodological standpoint, producing a rigorous renovation passport requires a detailed energy model of the existing building, scenario analysis for improvement pathways, estimation of embodied and operational carbon emissions, and coordination with regional certification registries. | Solar energy integration in new construction is addressed directly by EPBD 2024 with binding timelines. According to MITECO, in the Spanish implementation guidance for the directive, all new public and non-residential buildings with a usable floor area above 250 square metres must have solar installations in place before 31 December 2026, where technically and economically feasible. This obligation is extended progressively to other building categories in subsequent phases. This requirement overlaps with provisions already established in the CTE DB HE (Basic Document on Energy Saving), which in its 2019 revision introduced minimum solar contribution requirements. EPBD 2024 raises that threshold and makes it binding within stricter timescales, establishing solar energy as default infrastructure rather than an optional enhancement. For projects in energy generation and distribution, this convergence between building regulation and energy regulation creates a technically complex working context requiring coordination across building services, structural engineering, and planning consent disciplines. | The regulatory calendar under EPBD 2024 extends well beyond May 2026. According to BUILD UP, the first binding life cycle assessment (LCA) requirements will begin to apply to large buildings from 2028, extending to all new buildings in 2030. In the context of EPBD 2024, LCA measures the global warming potential across the full building life cycle, including construction materials, the operational phase, and demolition, expressed in kilograms of CO2 equivalent per square metre per year. This means that projects currently being designed for large-footprint buildings should already incorporate LCA methodologies into their technical documentation in order to be compliant when those requirements enter into force. The integration of LCA into building information models, following information management protocols such as those described in ISO 19650, is the most efficient means of ensuring that documentation is coherent, traceable, and updatable throughout the asset's life. This is particularly relevant for industrial and advanced manufacturing facilities, where buildings combine high technical loads with floor areas that frequently exceed the thresholds triggering the most demanding obligations. Additionally, according to the European Commission Directorate for Energy, Member States are required to submit their final national building renovation plans by 31 December 2026, quantifying the existing building stock, decade-by-decade renovation targets, and associated financing measures, providing the priority framework against which national and European funding calls will be aligned. | The practical implications for building owners and engineering teams operating across the EU are significant and concurrent. EPCs issued before May 2026 may require revision if they do not comply with the Annex V format, particularly in property transactions occurring after that date. Building owners with renovation plans should assess whether a renovation passport is preferable to isolated interventions, given that the passport may be a prerequisite for accessing certain public financing lines. New construction projects exceeding 250 square metres in public or non-residential use must assess the technical and economic feasibility of solar installation from concept design stage, with any exception duly documented. Engineering teams working on large buildings should incorporate LCA procedures into their workflows now to be ready for the 2028 requirements. Energy audits carried out under existing national transpositions of the Energy Efficiency Directive, such as the Spanish Real Decreto 56/2016 which requires large enterprises to conduct audits every four years, must be coherent with the new indicators introduced by EPBD 2024, in particular the global warming potential and the smart readiness indicator (SRI). | EPBD 2024 does not operate in isolation. It forms part of a broader regulatory stack that, across the EU, intersects with national building codes, thermal installation regulations, energy audit requirements, planning legislation, and increasingly with EU taxonomy criteria for sustainable finance. For engineering consultancies and asset managers, the most effective response to this complexity is a structured compliance framework that maps each obligation to the relevant deadline, identifies the technical data required to fulfil it, and integrates that data into a single auditable information environment from project inception. NOVTRIQ's technical team applies this approach across building typologies in the UK, Europe, and the UAE, combining energy modelling, BIM management aligned with ISO 19650, digital twin engineering, and sector-specific expertise to support clients through regulatory transitions of precisely this kind.
