Lower Costs Per EPC
We aim to significantly reduce the cost of generating an EPC by introducing a standardised, open-source solution. By streamlining the calculation and verification process, EPCs will be quicker and cheaper to produce — without sacrificing quality or accuracy.
More Value From Each EPC
Each EPC will offer greater value — both financially and practically. From lower energy bills and higher property values to reduced carbon emissions and better indoor comfort, OpenBEP4EU helps unlock the full potential of EPCs. Our approach ensures certificates are more accurate, consistent, and better aligned with real-world energy performance, encouraging meaningful actions to improve efficiency.
Faster Return on Investment
Our approach makes EPCs not just cheaper, but smarter. The improved quality and reliability of our solution means investments in energy efficiency can deliver results faster, offering quicker payback and long-term benefits.
Designed to Be Understood
Energy performance shouldn’t be confusing. OpenBEP4EU is committed to making energy assessments clear, approachable, and easy to understand—for everyone, not just technical experts.
Project Deliverables
Deliverable D2.1
User Needs and Requirements for the OpenBEP4EU Toolbox
What it is
This deliverable sets out the user needs and functional requirements that guide the development of the OpenBEP4EU toolbox for harmonised Energy Performance Certificates (EPCs) and Smart Readiness Indicators (SRIs).
Why it matters
Harmonisation only works if tools respond to real-world use. This report identifies what different user groups—such as public authorities, assessors, software developers, building owners, and financial institutions—need from a shared calculation engine. It translates those needs into concrete requirements for transparency, interoperability, data handling, and adaptability to national contexts, ensuring that technical development supports both policy goals and practical use.
Who is it for
Anyone interested in how OpenBEP4EU ensures that its technical tools are grounded in user needs, including policymakers, system developers, and stakeholders involved in EPC and SRI implementation across Europe.
Deliverable D2.2
Advanced EU Kernel EPC Engine
What it is
This deliverable is the fully developed backend of the EU Kernel EPC Engine, designed to meet the latest standards outlined in the European Performance of Buildings regulations and the Energy Performance of Buildings Directive recast provisions.
Why it matters
Member States’ EPC calculation methods vary widely, and the EPBD recast now requires broader EPC indicators. The OpenBEP4EU engine provides a transparent, reusable, hourly EPB-based implementation that generates the calculation-dependent EPC indicators (primary energy, final energy, on-site renewable share, operational GHG emissions) from a common computational basis. Its core modules are released publicly, so national systems and developers can inspect, reproduce, and integrate them rather than building from scratch.
Who is it for
This document mainly serves three audiences in EU building energy performance and EPC implementation: Software developers, EPB standards experts, and national authorities and policy-makers.
Deliverable D2.3
Integrated SRI for Enhanced Energy Performance Assessments and Financing Practices
What it is
This deliverable presents the development and integration of the Smart Readiness Indicator (SRI) Kernel Engine within the EU Kernel Energy Performance Certificate (EPC) architecture,
Why it matters
The SRI Kernel makes smart readiness assessment a standardized, automated, and validated part of the EPC process instead of a separate, inconsistent exercise. It enforces the SRI methodology through strict input validation, so results are comparable across tools and Member States. It plugs into the EU Kernel EPC Engine, so smart readiness results appear alongside standard EPC metrics and support benchmarking and before/after renovation analysis. Its outputs can also serve as supplementary indicators of digital maturity and renovation readiness for financing schemes, one-stop shops, and policy monitoring, helping implement the EPBD’s smart readiness provisions and EU data-harmonisation goals.
Who is it for
It is mainly relevant for EPC tool developers and technical teams who need to integrate SRI computation into EPC workflows, building audit platforms and digital twin environments, national authorities and policy-makers implementing the EPBD’s smart readiness provisions and monitoring or benchmarking at regional, national, or EU level, and financing institutions, one-stop shops, and refurbishment facilitators who can use SRI outputs as supplementary indicators of digital maturity and renovation readiness.
Deliverable D3.1
Innovative Inspection Procedures Handbook
What it is
This handbook explains how building inspections can become more consistent, digital, and reliable across Europe.
Why it matters
Energy Performance Certificates depend on the quality of on-site inspections. This deliverable sets out practical inspection procedures that align with EU standards and support more accurate energy assessments. It shows how digital tools, structured data collection, and clearer inspection steps can reduce errors and improve comparability between countries.
Who is it for
Energy assessors, national authorities, and organisations responsible for building inspections who want more reliable and future-proof EPC processes.
Deliverable D5.2
Internal and External Communication
Channels and Resources v1
What it is
This deliverable maps how OpenBEP4EU communicates its work during the early phase of the project.
Why it matters
Clear communication is essential for transparency and engagement. This document describes the project’s website, social media, events, and internal coordination tools, and explains how they are used to share progress, involve stakeholders, and build awareness of open building performance data.
Who is it for
Stakeholders who want to understand how OpenBEP4EU shares information, engages partners, and builds visibility during the project’s initial stages.
Deliverable D5.5
After-LIFE Conservation Plan
What it is
This plan explains how OpenBEP4EU results will be maintained, used, and expanded after the project ends.
Why it matters
Many EU projects deliver strong results that fade once funding stops. This deliverable sets out how OpenBEP4EU’s open-source tools, calculation engines, and data infrastructure can remain available and useful over time. It describes value propositions, potential users, and paths to long-term sustainability while keeping the project’s open and public-interest character.
Who is it for
Public authorities, technology providers, researchers, and others interested in long-term access to harmonised EPC and SRI tools.
Deliverable D5.8
Internal and External Communication
Channels and Resources v1
What it is
This updated communication strategy reflects how OpenBEP4EU’s outreach evolves as results mature.
Why it matters
As the project moves from awareness-raising to concrete outputs, communication needs change. This deliverable explains how different audiences—citizens, technical experts, financial actors, and policy bodies—are addressed at different stages, and how articles, events, and digital channels support understanding and uptake of results.
Who is it for
Anyone interested in how OpenBEP4EU structures its public communication and ensures that results are understandable and accessible beyond the consortium.
Deliverable D5.9
After-LIFE Conservation Plan v2
What it is
This updated version of the After-LIFE Conservation Plan defines the strategy for the long-term sustainability, governance, exploitation, and market uptake of the project results beyond the duration of LIFE funding.
Why it matters
The document explains how the OpenBEP4EU assets, tools, methodologies, and knowledge will continue to deliver value to the European building sector after project completion. It provides a roadmap for maintaining and further developing the
OpenBEP4EU ecosystem beyond project completion.
Who is it for
Public authorities, technology providers, researchers, and others interested in long-term access to harmonised EPC and SRI tools.
