As a form of Demand Side Management to avoid capacity constraints in the grid, the new tariff seeks to reduce consumption peaks by incentivising householders to even out electricity use and shift to nighttime. We examine the perspectives of 13 representatives from grid companies as well as 22 householders and study the process of developing the tariffs, in which the researchers took part at certain times. We draw on previous studies on experts’ perceptions of end-users, social practice theory, and energy justice, and we employ the concept of flexibility capital to examine the situation of the participating households. The findings partly confirm results from previous studies showing that experts may have a simplistic view of end-users and by observing an unequal distribution of flexibility capital across the studied households. However, the study contributes to the field by observing a link between householders’ sentiments towards the new tariff and their respective levels of affluence and flexibility capital. Then, we explicitly address justice perspectives related to the tariff’s introduction as perceived by grid companies and householders and find that both groups voice a need to acknowledge the situation of different kinds of end-users. We discuss the results from an energy justice perspective and observe that details in the design of a DSM mechanism may dampen its negative effects.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"16 7","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-023-10153-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42299750","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 choice to invest in an improved piece of equipment rather than a simple in-kind replacement is driven by many factors, including costs, performance, and familiarity with new technology options. Engineering models that account for equipment stock turnover, such as ENERGY 2020, typically assume that this decision is primarily driven by the difference in marginal costs: higher up front capital costs must be, at minimum, balanced by lower lifetime energy costs for an upgrade to be pursued. Stock turnover analysis requires detailed data inputs regarding the costs and performance of new equipment. For simplicity, a common approach is to develop assumed correlations that reflect the trade-off between marginal capital cost and efficiency and compare these to energy prices to select an efficiency level for new equipment. In this study, we present a novel method to develop such trade-off curves based on a technology-explicit approach rather than a qualitative correlation assumption. We generate trade-off curves for two common types of industrial devices: electric machine drive and natural gas steam generation for the case study of the Canadian pulp and paper sector. The curves demonstrate that the efficiency of new devices can be expected to vary significantly based on energy prices. At current energy prices, we find that newly purchased machine drive and steam generation devices would have an optimal efficiency level of 91% and 75%, respectively.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"16 7","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-023-10150-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4848927","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}

Indeed, informal firms are mostly very small and generally use less energy than formal firms and do not need sophisticated and costly electrical equipment for their operation. We mobilize data from the Enterprises Survey conducted in Cameroon in 2009 and 2016 by the World Bank. We first apply the data envelopment method (DEA) to determine the technical efficiency scores of firms. We estimate average efficiency scores of 25% and 42% for 2009 and 2016 respectively, which represents an improvement over the period. We then assess the impact of powers outages and other exogenous factors on the efficiency scores using the Tobit model as the efficiency scores are between 0 and 1. The results show that the occurrence of powers outages, the number of powers outages events, the duration of a powers outages event, the total cost of electricity and the losses due to powers outages negatively and significantly affect the efficiency scores of manufacturing firms in Cameroon in 2009 and 2016. However, informal firms are more resilient to powers outages than formal firms. Furthermore, sensitivity analyses using quantile regression confirm the robustness of our estimates. These results call, first, for improving the quality of private and public electricity infrastructure in order to reduce the occurrence of powers outages. Secondly, these results suggest the development of substitutes to electric energy to cope with long periods of powers outages.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"16 6","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44439473","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}

Building sector, in particular, accounts for approximately 40% of overall energy use. Urban planners and decision-makers have a significant responsibility to achieve sustainable energy and climate objectives. Urban building energy modeling (UBEM) has increased in popularity in recent years as a tool for calculating urban-scale energy use in buildings with limited resources, and that facilitated the formulation of new energy policies. However, published studies of UBEM methodologies and tools lack comprehensive examinations of the potential limitations of research and the prospects of future opportunities. This paper provides a complete conceptual framework for UBEM based on extensive literature reviews and prior researchers’ work. In addition to providing a comprehensive understanding of the various UBEM approaches and tools, future research directions are explored. The results demonstrate that earlier researches did not adequately account for input uncertainty and lacked proper simulation and calibration control for algorithms/models. These challenges not only increased the workload and computational burden of modelers but also diminished the precision of model calculations. In response, this paper provides targeted recommendations for each essential phase of the present UBEM workflow, namely model input, model development, and model calibration, to address these limitations, as well as a comprehensive analysis of future prospects. The main aim of the research is to further UBEM development as a faster, more accurate and multiscale supportive tool and establish a framework for future UBEM methods.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"16 6","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44379491","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}
