Energy retrofit of residential Building clusters. A literatue review of crossover recommended measures, polices instruments and allocated funds in Spain Ibañez Iralde, Nadia Soledad; Pascual, Jordi; Salom, Jaume The building sector is responsible for more than 40% of final energy consumption in Europe; consequently, retrofitting existing buildings can significantly contribute to mitigate greenhouse emissions. Nevertheless, although the European Union has introduced relevant policy instruments, up to now the annual retrofit rates are considerably low with an average of 0.2% at European level. Understanding the past would support the success of the new strategies, such as the recent ones launched through the New Green Deal, which reinforces the importance of renovating existing buildings stock, as the main aim of the renovation wave. As a starting point for assessing the main challenges to allocate the Recovery funds, this paper provides a review of Spain’s relevant literature to clearly define the characterization of the existing building stock, which actions have been typically considered under the scope of retrofits, and which strategies have been implemented until now, considering both, private and public initiatives and public financial schemes. The present work has a strong focus on energy-related strategies, although other interrelated actions are mentioned, such as accessibility measures and interior refurbishment of dwellings. Differences and similarities within these approaches are presented through the analysis of 27 relevant references of retrofitting actions and 52 references of financial mechanisms. As in Spain 93% of multifamily buildings were constructed prior to the national transposition of the first Energy Performance Building Directive (EPBD), and therefore are in need of deep energy renovations, the retrofitting of multifamily buildings topic has been widely addressed, even though often in a disjointed manner. The study suggests that although historically there have been several recommended strategies, few are conceived as integral actions, only 15% of the intervention packages refer passive and active energy-related measures and renewable energy incorporation. Furthermore, considering the antiquity of the building stock and the advantage of addressing the topic through clusters, only 63% of the resources directly refer these actions to specific clusters among the six distinctive periods, although in most cases focusing their recommendations on buildings constructed before 1980 where the worst energy performance buildings are concentrated. Concerning public financial and funding instruments, the research illustrates that there has been a substantial increment of programs over the last years promoting energy-related measures, renewable energy and other complementary aspects such as accessibility and interior renovations, mainly for older clusters. Nevertheless, the funds constitute only 8% of the necessary declared investments, which along with the dispersion between the different procedures and the complexity of the processes, have significantly reduced the global impact of these actions without generating robust and oriented market dynamics. Despite the several resources found, both financial instruments and guidelines tend to describe in more detail strategies related to heating demand and consumption and not delve into other relevant actions for warmer climates, fact associated both to the dynamics coming from other countries, and to a vision of the past in which people do not consume refrigeration. This clear focus on heating loads rather than cooling could present limitations for warmer regions in the near climate- change future.

Evaluationg the effectiveness of public subsides for energy-efficient retrofit: A comparative study of two next-generation programs with standard market interventions in Catalonia Ibañez Iralde, Nadia Soledad; Pascual, Jordi; Martí Audí, Núria Assessing the impact of past and current renovation efforts is essential for refining decarbonisation mechanisms and ensuring the effective use of public resources. In this context, this paper examines the effectiveness of two Next Generation subsidy schemes implemented in Catalonia between 2021 and 2024. It evaluates their impact on energy demand, non-renewable energy use, and CO2 emissions, while also assessing the associated investment costs. In addition, the analysis compares subsidised interventions with a reference sample of standard market interventions carried out without financial support. The analysis revealed that the subsidies reached 35% of the region and 15% of low-income municipalities, with a scope comparable to that of standard interventions. The study also emphasises that the impact of the samples remained broadly similar, noting only a few minor differences when more restrictive conditions were introduced. Furthermore, the study shows that although in some cases there is a clear improvement in the Energy Performance Certificates, in many others the impact is significantly lower, with some even remaining in conditions clearly below the decarbonisation objectives. The assessment also identifies a lower effect on energy demand compared to overall energy consumption and emissions, as well as a correlation between energy savings and climate, with colder climates yielding greater results. Finally, territorial urban–rural disparities in terms of investment costs are revealed. These findings underscore the need to redesign the instruments to consider geographic and social aspects, effectively engage more of the population, particularly the vulnerable groups, and facilitate integral interventions that surpass conventional market practices.

Special Issue on IberSPEECH 2022: Speech and Language Technologies for Iberian Languages Pérez Córdoba, José Luis; Alías-Pujol, Francesc; Callejas, Zoraida ThisSpecial Issue presents the latest advances in research and novel applications of speech and language technologies based on the works presented at the sixth edition of the IberSPEECH conference held in Granada in 2022, paying special attention to those focused on Iberian languages. IberSPEECH is the international conference of the Special Interest Group on Iberian Languages (SIG-IL) of the International Speech Communication Association (ISCA) and the Spanish Thematic Network on Speech Technologies (Red Temática en Tecnologías del Habla, or RTTH for short). Several researchers were invited to extend the contributions presented at IberSPEECH2022 due to their interest and quality. As a result, the Special Issue is composed of 11 papers that cover different research topics related to speech perception, speech analysis and enhancement, speaker verification and identification, speech production and synthesis, natural language processing, together with several applications and evaluation challenges.
