For this purpose, the authors analyzed the data of 1,552 households in Lahore division using Partial Least Square-Structural Equational Modelling (PLS-SEM). The key findings of the study showed that consumer’s sustainable energy consumption intentions and their energy conservation preferences are important determinants of sustainable energy consumption behavior, with energy conservation preferences also act as a significant moderator. It was observed that individuals with strong energy conservation preferences are more likely to translate their intentions into actual behavior, demonstrating the significance of these preferences in bridging intention-behavior gap. Moreover, our results reveal that individuals' attitudes and perceived behavior control indirectly impact their sustainable energy consumption behavior.

The European Commission mandates that all new buildings should be “zero emission buildings” (ZEB), aiming at a zero GHG emission building stock by 2050.

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}

Our results showed that most citizens were willing to invest, but would invest mainly low sums pointing at the need to establish investment mechanisms suitable for citizens. Moreover, the factors influencing willingness-to-invest differ significantly for each renewable type highlighting the need to leverage this differentiation in marketing strategies. While perceived barriers and economic motives were important for almost all renewable types, environmental attitudes were less influential suggesting that strategies using the argument of environmental benefits may be ineffective.
