Webinar 5. Exploitation of EPC for local, regional and national energy planning

The upcoming recast of the Energy Performance of Buildings Directive (EPBD) introduces the national building renovation plan to support the decarbonisation of the European building stock by 2050. This requires data and models to rank the overall energy and environmental performance of the building stock. Archetypes that representative of building clusters play a crucial role in the development of a national building renovation plan, because they encapsulate the heterogeneity of the building stock characteristics. By exploiting bottom-up energy models, the archetype-based approach enhances accuracy in urban energy modelling and, in the same time, reduces model complexity. The content of Energy Performance Certificate (EPC) databases, properly processed to remove erroneous data, represents a core source of information to create the archetypes, to analyse the performance status of the building stock, and to assess the effectiveness of renovation strategies. 

 

This webinar explores the potential to use EPC databases to develop an archetype-based urban building energy model, as devised in the TIMEPAC project. The webinar offers comprehensive training in the statistical analysis of the EPC database, with the goal of leveraging it for benchmarking initiatives. Examples of energy renovation scenarios both at the individual building scale (e.g., by exploiting the information provided in the Building Renovation Passport), and at broader building stock levels will be provided. The training materials cover the workflow of statistical analysis on EPC databases, quality control activities for EPC data, and the development of building stock models.

Introduction to EU legislation related to long-term renovation strategies of the building stock

EN

The session provides an overview of the legislative context and requirements for the deep renovation of the European building stock, which has been included in National Energy and Climate Plans and National Long-Term Renovation Strategies. It will also offer an overview of activities conducted in the framework of the project Concerted Action EPBD (CA EPBD). This project addresses various elements of EPBD and aims to contribute to the reduction of energy use in European buildings through the exchange of knowledge and best practices.

Identification and collection of relevant data from EPC databases to map the energy status of the building stock

EN

Identifying and collecting relevant data from EPC databases is a crucial step in mapping the energy status of the building stock at various scales. This session will cover different types of data available in EPC databases and the techniques used for data extraction. The challenges and limitations associated with using EPC data to map the energy status of the building stock will also be addressed, including issues related to data quality, reliability, and the need for data standardization and harmonization to facilitate data collection and analysis to develop local, regional and national energy plans.

Techniques and control activities on the EPC data to evaluate the reliability of certificate information

EN

This session provides participants with a comprehensive overview of the methods, including techniques and control measures, to assess the accuracy of EPCs. A quantitative procedure for checking the quality of EPC data developed in TIMEPAC will be presented, which focuses on customized rules and scores to evaluate data reliability. It involves comparing the assigned overall EPC score to a predetermined threshold value, beyond which the certificate is deemed unreliable. The methodology is based on standardized, harmonized, and adaptable rules that can accommodate country-specific variations, ensuring the reproducibility of the process.

Data clustering techniques to characterize representative buildings

EN

In the process of assessing building energy and environmental performance in urban areas, clusters are typically formed by categorizing actual or theoretical residential and non-residential buildings based on common characteristics widely recognized by the scientific community. These characteristics encompass various factors such as climatic zones, usage categories, construction periods, size, shape, and key performance indicators. To compile the information to create these clusters, diverse data sources are utilized, including local, regional, or national databases, statistical surveys, and technical standards. The emphasis placed on EPC databases as the primary source of data for cluster formation is of particular importance.

Bottom-up energy model using EPC data as a support tool to assess the energy performance of building stocks

EN

This session will present some of the most recognized approaches to developing building stock energy models with a focus on the model adopted in TIMEPAC.  This model leverages the concept of building typology, which serves as a framework for analysing the energy balance at national or regional scales. This model exploits the EPC database as a supportive instrument to create archetypes to be used in identifying the energy performance of the building stock by means of a bottom-up  approach. A statistical analysis is performed to derive the archetypes after the processes of data quality checking and data clustering presented in the previous sessions.

Making use of renovation roadmaps: from the building to the building stock exploiting the renovation passport data

EN

The renovation roadmap aims at transforming a building towards a zero-emission building by 2050. Despite some challenges associated with the long-term horizon of the renovation passport (e.g. how to deal with the development of costs and technologies within the 2050 time horizon), there are potential benefits for national building renovation plans. This presentation explores the potential benefits of the building specific renovation roadmap as a data source for national building renovation plans. As not only plans but also reports on the evolution of the national building stock will be required, the aspect of tracking the implementation of renovation measures will be of great importance. Options in this regard in connection with the renovation passport are presented.

Energy saving assessment in building stock deep renovation scenarios through EPC data

EN

Accurate modelling of the current energy performance of the building stock is essential to unlock the significant potential for energy savings associated with its refurbishment. This session will provide a comprehensive overview of the entire process, which includes: 1. Establishing a knowledge base on the current state of the building stock through statistical analysis of  EPC databases; 2. Exploring various refurbishment scenarios, considering efficiency measures and retrofit rates, and 3. Comparing the potential CO2 reductions resulting from these scenarios with climate protection targets. The session will cover the processing of EPC data, which encompasses climate conditions, usage categories, geometric features, envelope thermal characteristics, types of HVAC systems, and energy performance indicators.
