In this field, Ground Source Heat Pump systems represent one of the most promising solutions because of the much more favourable temperature of the ground if compared to ambient air, which is affected by weather conditions. Furthermore, air source heat pumps are further penalized by the defrosting cycles of the finned coil heat exchanger during the heating period. The continuous reduction of the building peak thermal loads and energy needs, thanks to the improvement of standards and European targets in the building sector, has revived the interest of operators in horizontal geothermal systems. In the past, this type of ground heat exchangers was normally not considered due to the large space needed for their installation. In the literature there is a lack of works and research of ground source heat pump systems coupled with shallow flat-panel ground heat exchangers. The present work improves the knowledge of this latter technology. The study analyses and compares the thermal behaviour of flat-panel and vertical 2U ground heat exchangers loops by means of using TRNSYS simulation tool. The simulations have been used to obtain the energy performance of the ground loops coupled with the heat pump. The comparison highlights the differences between different case studies and how the flat-panel ground heat exchangers field is a possible alternative to the current systems.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 7","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-025-10344-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144861486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, a panel analysis was conducted to control for individual effects, utilizing both the experimental data and the responses to a follow-up questionnaire. The dependent variables in the panel analysis were the reaction times and number of round trips between the AOIs. The findings reveal that energy labels in real estate advertisements significantly enhance consumers’ understanding of energy-saving standards. Furthermore, the results underscore the critical role of label design. Specifically, positioning reference information on the left side of the label improves clarity. If a property exhibits poor energy-saving performance, emphasizing the deviation from the energy-saving standard proves effective. Moreover, this study suggests that using energy labels is effective regardless of the degree of consumers’ concern about the environment. Given that energy labels raise consumers’ awareness of household energy standards and promote energy-saving behavior, the early implementation of labeling for all properties, whether for sale or rent, is strongly recommended.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 6","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-025-10342-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The decarbonization process requires the deployment of non-programmable renewable energy sources in power systems, requiring unprecedented attention to grid flexibility and securityIn this context, Data Centers can provide balancing services by Demand Response strategies, modifying or temporarily reducing their electrical consumptions during specific times.

On this basis, a numerical energy model developed using TRNSYS software has been calibrated and validated. Finally, the possibility for DC to participate in the electricity flexibility market a novel demand response strategy that exploits the fluctuations of indoor air temperature and humidity has been investigated.

Modifying consumer behavior, particularly within the residential sector, which accounts for a substantial share of global energy consumption and carbon emissions, is crucial for reducing consumption and achieving sustainable development. Aiming to integrate the concepts of Responsible consumption (RC) and behavioral interventions within the Theory of Planned Behavior (TPB) theoretical framework, this research seeks to develop a conceptual model to explain and promote responsible energy consumption behavior. Research data were collected through questionnaires and expert interviews. Data analysis was conducted using the Fuzzy Delphi Method, Structural Equation Modeling (SEM) in SmartPLS4 software, and scenario writing employing the Cross-Impact Balance (CIB) method. In this study, Behavioral interventions (individual or combined) designed based on the principles of responsible innovation (RI) alongside TPB variables play a key role. The results indicated that combined interventions significantly impact the intention and behavior of Responsible consumption and, as mediating and moderating variables, play a significant role in translating intention into behavior. In contrast, individual interventions alone exhibit weaker effectiveness. Furthermore, 8 future-oriented scenarios for reducing household energy consumption were designed, revealing that participatory and supportive scenarios focused on promoting Responsible consumption behavior have a greater impact on behavior change. By integrating RI, TPB, and behavioral interventions within an analytical and scenario-based model, this research provides a novel framework for energy policymaking in developing countries.

Over the past decades, the average floor area per person has increased steadily, resulting in higher energy demand for building materials, heating and cooling. However, the distribution of floor area is not equal across different demographic groups and household compositions. Redistributing floor area offers a significant opportunity to save resources and reduce the need for new construction by avoiding unnecessary consumption. Strategies such as moving, sharing and rearranging can facilitate this redistribution in the residential sector. In order to assess the feasibility of these strategies, this paper examines the current residents’ behaviour in the residential sector regarding space use and explores the potential for change. It draws on empirical data from an online survey conducted in Germany, Sweden, Poland and Portugal. By conducting a cluster analysis of the collected data, the paper identifies two groups with the highest potential for change in residential space use. It examines their willingness to change their space use patterns and investigates the acceptance of specific strategies that could lead to a reduction in the need for new construction in the residential sector. In order to promote more efficient use of space in the residential sector, the paper recommends encouraging space sharing, supporting structural changes in dwellings, and providing incentives for moving from under-occupied dwellings. It advocates for the implementation of tailored policies that consider the characteristics of each group, along with targeted awareness-raising efforts to increase policy acceptance.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 6","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-025-10343-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
