Advanced methods and tools for energy rehabilitation of buildings from a holistic perspective

The recently adopted revision of the Energy Performance of Buildings Directive (EPBD) recommends the use of digital modelling and simulation tools in all phases of building design, construction and renovation to improve the energy performance of buildings. These technologies are particularly suitable for creating building renovation passports and digital logbooks, while facilitating the incorporation of the Smart Readiness Indicator and the contribution of buildings to global warming throughout their life cycle. Their use allows for a more comprehensive assessment over time and facilitates the transition from one-off certification to continuous assessment of energy performance.


This course serves as an introduction to methods and tools for building performance assessment and building renovation. It begins by outlining the recently approved Energy Performance of Buildings Directive (EPBD) and then explores the application of BIM technology in generating Energy Performance Certificates (EPCs) during the renovation process. The workflow will adhere to the guidelines from TIMEPAC regarding the Building Renovation Passport, considering energy consumption, economic, and environmental factors. Exercises will focus on both public and residential buildings.

Challenges of the new Energy Performance of Buildings Directive

23/5/2024 9:45–10:00 (CET) | CA

An introduction to the recently approved Directive, a crucial tool for meeting the EU's decarbonization goals. The new legislation mandates Member States to develop national plans to ensure that all new buildings reach zero emissions by January 1, 2030. This session will focus on the use of digital models to generate Energy Performance Certificates and building Renovation Passports, and the creation of roadmaps for building renovation.

Generating enhanced EPC with BIM data

23/5/2024 10:00–10:45 (CET) | ES

The integration of BIM and EPC is a long-term goal, but it faces several obstacles, mainly those arising from the interoperability between modelling and simulation tools. To advance this integration from existing tools, TIMEPAC has developed a set of guidelines for generating an EPC from a digital model, using current technologies and adopting open interoperability standards. These guidelines cover BIM workflows for various modelling scenarios, with the aim of contributing to the establishment of protocols for energy efficiency certification applicable across the European Union.

Creating a BIM model for EPC generation: a municipal building

23/5/2024 11:15–13:45 (CET) | ES

In this hands-on session, two BIM workflows will be demonstrated using the Common Data Environment (CDE) Firstly, the IFC Builder will be utilized to create an analytical model from floor drawings, which will then be linked to the energy certification program CYPETHERM HE Plus. Following this, another workflow will be presented using a Revit model. This will involve verifying the IFC file and extracting the analytical model through the Open BIM programme. Both workflows will be applied to a practical case of renovating a public building.

Certification along the renovation process

30/5/2024 10:00–10:20 (CET) | CA

Effective management of building energy data is crucial to achieve the objective of decarbonising the energy stock of buildings by 2050. The new Directive introduces a tool to facilitate this management: the digital building logbook. This logbook serves as a repository for all building-related data, including energy certificates and renovation passports. Access to this data by owners, managers, financial institutions, and other stakeholders will streamline the decision-making processes related to building renovation.

Building renovation passport

30/5/2024 10:20–10:45 (CET) | ES

The objective of this session is to introduce the building Renovation Passport, an instrument aimed at promoting building rehabilitation included in the new EPBD. We will delve into the key components of the passport and highlight examples illustrating its implementation across various EU countries, outlining the specificities of each case. Finally, we will briefly address the benefits, challenges, and obstacles associated with implementing this tool within the European context.

Generating BIM for a step-by-step renovation of a residential building

30/5/2024 11:15–13:50 (CET) | ES

In this practical session, we will focus on the generation of thermal models to calculate the energy consumption and evaluate the energy performance of a residential building, both for its current state and with the proposed improvements. We will use the CYPETHERM HE Plus software for this purpose. Each renovation measure will undergo analysis from energy consumption, economic, and environmental perspectives. The economic viability of these enhancements will be assessed using the CYPETHERM Improvements Plus software, while the Construction Price Generator will provide economic values and environmental indices for each one.
