In this context, local middle actors have been suggested as partners in deploying targeted energy support. Nevertheless, scarce research has engaged with them to assess if they are willing and capable of contributing, if they can reach households, and if they have unmet needs. In this research, we draw on the mapping of 198 local organizations and 34 semi-structured interviews conducted after deploying a pilot energy support service in Setúbal, Portugal. Interviews characterized the organizations and target audiences, assessed energy literacy, explored potential collaborative roles, and recognized drivers, barriers, and solutions. Results show that most organizations are willing to disseminate activities, forward citizens, facilitate contacts, co-organize events, and participate in training. Half can identify vulnerable families for proactive support. Drivers include environmental concerns, community participation, and social support. However, few seem able to conduct energy support, hire/redirect staff, or participate in coordination. Scarce human resources, lack of time, other priorities, and financing concerns severely constrain local organizations. This case study finds some potential for local organizations to act as intermediaries in energy support, building on their communication channels and trusted relationships to fulfill specific roles. However, they are often hard-to-reach themselves and burdened with demanding activities. Thus, we suggest that fostering collaborations with local organizations is challenging but possible. It requires dedicated funding, time, and resources to empower, capacitate, and reward middle actors for their contributions in delivering energy support.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 7","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-024-10262-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142409530","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 incorporation of expanded polystyrene (EPS) and expanded perlite (EP) into cement mortar has shown enormous potential to improve overall thermal performance. This study aims to numerically evaluate the efficiency of using EPS and EP reinforced composites as coating mortars. First, several reinforced mortars were prepared by adding different proportions of EPS and EP to the cement mortar. The thermal, mechanical and microstructural performances of EPS and EP mortars were subsequently analyzed using Hot Disk and MATEST instruments as well as FTIR spectroscopy and XRD analysis. COMSOL Multiphysics software was then used to simulate the inner temperature variation of a hollow brick coated on both sides with the optimal reinforced mortar mix. The results showed that an increase in the amount of reinforcing material led to a reduction in both mechanical strength and thermal properties of the mortar. Optimum performance could be achieved by incorporating 2.5% expanded polystyrene into the mortar, which resulted in approximately 37%, 15%, and 26% reduction in thermal conductivity, thermal diffusivity, and volumetric heat capacity, respectively, compared to standard mortar. This thermal improvement was achieved while ensuring a satisfactory mechanical and chemical properties. By applying varying thicknesses of this reinforced mortar to the brick, the internal surface temperature was reduced by approximately 0.2–1.8 °C during periods of maximum flux exposure. Therefore, the application of these composites as a thermally enhanced coating mortar on building walls seems to be an adequate solution.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 7","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142415018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, there are relevant increases in the prices of energy and food, which are likely to raise poverty rates in low- and middle-income countries. It is concluded that the global emission reduction can vary between 5.1% and 50.3% depending on the SCC used, and only ten countries explain 77% of this reduction. In addition, global emissions reduction falls if data from a more recent base year is used, demonstrating that the structural transformations of the economy also strongly affect the impacts of carbon pricing.

It is also important to consider other environmental effects to avoid that climate benefits come with unintended consequences. Here, we explore the life-cycle environmental performance for a ZEB in a case where electricity and heating are largely fossil-free. The assessment concentrates on i) environmental impact of the use stage in relation to the product stage, ii) the interrelation between different energy sources, with focus on household electricity, and iii) the performance for more impact categories than primary energy use and climate change. While our results generally support the use of ZEBs from an environmental perspective, they also show that the climate benefit in this setting is marginal. However, given that energy systems are connected and energy savings in one place can reduce the demand for fossil energy elsewhere, the climate benefit of ZEBs is likely underestimated. Besides methodological implications for future studies, this indicates that current EU policy is promising, as incentives for implementation of ZEBs are unaffected by domestic effects.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 7","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-024-10253-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204922","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}

Addressing energy consumption in buildings involves two primary facets: accurately predicting and optimizing load demand. This research aims to address the challenges of load demand prediction in the context of building energy consumption. It introduces innovative approaches, including optimized support vector regression (SVR), temperature factor consideration, and the integration of Trombe walls (TW), ultimately contributing to more accurate load demand forecasts and enhanced energy efficiency. To enhance the precision of load demand prediction, we introduce a novel variable that quantifies deviation from the ideal temperature; a key factor in energy usage. This innovative temperature factor plays a pivotal role in forecasting the load demand more accurately. Leveraging this novel approach, we employ an optimized (SVR) that considers weather conditions. The parameters of a radial basis function kernel-based support vector regression (RBF-SVR) method are fine-tuned through an improved particle swarm optimization algorithm (IPSO). In addition, installed TW prove highly effective in reducing building energy consumption by harnessing and redistributing heat, consequently improving the load demand profile. We employ mathematical models to analyze the impact of Trombe walls on predicted load demands, demonstrating that our proposed method yields low mean absolute percentage error (MAPE) when applied to sample buildings. The findings reveal that our method significantly enhances the accuracy of energy usage prediction, while the installation of Trombe walls results in a remarkable reduction of load demand – by 19.32% in winter and 16.24% in summer, thereby promoting energy efficiency and sustainability.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 7","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
