The Energy Efficiency Certificate, Energy Savings Certificate and the EPBD building benchmark in Spain

With the decarbonization objectives set in the building sector for 2030 and 2050, and specifically those derived from the approval of the European directive on energy efficiency in buildings (Directive (EU) 2024/1275), which will require calculating the global warming potential of new buildings from 2028 for new buildings with a surface area greater than 1,000 m2 and 2030 for all newly constructed buildings, and will establish limit values ​​for said indicator starting in 2030, understanding the impact of the carbon footprint of materials on the total life cycle of the building becomes increasingly relevant. Objective: this session aims to first inform about the implications of the approval of this European directive on the construction sector and the new obligations to be met within the deadlines of the coming years. Likewise, it is intended to make known the processes that the MIVAU is carrying out in the transposition of this directive and its support in studies that are being carried out by agents in the sector: the INDICATE project carried out by the GBCe and the University of Seville and the BENCHMARK study of buildings in Spain carried out by IECA together with ARUP. Presentation 1. MIVAU: Requirements of the EPBD directive and transposition process. Criteria for the preparation of the roadmap for the decarbonization of the construction sector in Spain. In this first presentation, the ministry will explain the requirements of the directive and the deadlines for its implementation: the obligation to calculate the global warming potential and the limit values ​​for it. The criteria that have been used to establish the common framework for calculating global warming potential and the process to prepare the roadmap with limit values ​​for the period 2030-2050 will be explained in detail, and which will have to be notified to the European Commission no later than January 2027. Presentation 2. IECA: Benchmark Study of the Environmental Impact of Buildings in Spain. IECA, Spanish Institute of Cement and its Applications, with the support of the Ministry of Housing and Urban Agenda, is carrying out a study to prepare a national benchmark on the average carbon footprint of a typical building in Spain, in order to guide the roadmap that the ministry will have to prepare. This presentation will show the preliminary results and methodology used in this study, based on representative scenarios of the Spanish market and industry data, taking into account the different representative climatic zones in Spain. The study will cover the following typologies: single-family residential, block residential, offices, industrial-logistics and shopping centers. Presentation 3. GBCe: INDICATE Project Presentation of the results of the INDICATE project and the work methodology used, based on scenarios resulting from theoretical models that combine different climatic zones, seismicity scenarios and construction typologies. The study has addressed 6 building typologies that include 5 different residential configurations, an office building typology and a separately modeled basement.
