The environmental sustainability of universities was critically analyzed recently. These bodies can contribute to the sustainability of cities due to their social role in shaping the future generations. The aim of this work is to analyze Urban Building Energy Modeling with a place-based approach using the open-source software QGIS in predicting energy production with photovoltaic solar technologies on the rooftops of the central university campus of Politecnico di Torino. This modeling can help in assessing the energy security and affordability of current and future sustainable scenarios considering their impact on climate change. This study evaluates the accuracy of urban scale QGIS-based energy modeling with a comparison of measured data available from the monitoring activity of LivingLab of Politecnico di Torino, the free tool PVGIS, and the web tools of ENEA. The QGIS modeling accuracy depends on the different precisions of the Digital Surface Model used to describe the built environment (i.e., 1 m or 5 m) and the climate input data (monthly and annual diffuse-to-global radiation and Linke turbidity factor). Moreover, this assessment can be used to map the results of new photovoltaic systems improving the energy and environmental performance of university campuses. The results of this work shed light on the significance of different input data for energy simulation tools at neighborhood-urban scale. The result shown accuracies in PV production of 10 to 37% with different spatial resolutions of the 3D built environment and of 14 to 15.2% for temporal resolution of solar irradiation variables.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 5","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-024-10233-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141400386","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}

It is also a hotspot of climate change and socio-economic and political turbulence, which inflate the already flammable conditions and reinforce existing local vulnerabilities. Some of the most arduous challenges of cities relate to the built environment – although vital for human well-being, buildings rarely offer both sufficient and affordable shelter to their inhabitants. With energy performance regulations coming into effect during the past three decades, a considerable proportion of the worldwide building stock had already been constructed and is now ageing and inefficient. Harmonising the energy performance of buildings at a sufficient level requires common objectives and priorities, and the EMME region consists of nations with different governance and regulations. Scarce literature exists on the existing operational frameworks, and this study aims to offer an overview of the built environment policy scene in the EMME region, identifying gaps, good practices and prospects. The study draws from scholarly literature, national and international regulations and other document sources, as well as local experts. This work finds that although most EMME countries participate in and embrace international agreements, they act individually and not collectively, confirming our hypothesis that the policy agenda reflects the diverse characteristics of the region. By recognising standing failings and strengths, moving forward becomes a possibility through the adoption of integrated governance, common policy agendas and financing mechanisms to create sustainable urban centres inhabited by resilient and equitable communities.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 5","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-024-10217-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141259799","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}

It adopts a difference-in-difference model to assess the effect of ECRTS on energy efficiency. The research finds that ECRTS improves energy efficiency of enterprises, and ECRTS can improve energy efficiency by promoting technological innovation and optimizing the efficiency of capital allocation. Further, ECRTS is more conducive to improving the energy efficiency of state-owned enterprises, enterprises with executives financial background, high pollution enterprises, and enterprises in regions with low resource endowments. Moreover, the improvement of energy efficiency can further enhance the value of enterprises after enterprises participate in ECRTS.

It is argued that interventions in individual behaviours are subject to attrition over time following the withdrawal of the intervention. Evaluation of these arguments is difficult since the conditions and composition of households change over time, making it hard to isolate the effects of a behavioural intervention several years later. Social practice theory argues for interventions that do not target individual attitudes or behaviours but focus instead on household practices (such as laundering and heating homes), and the underlying notions of cleanliness and comfort that are the causes of energy use in households. In contrast to behaviours, practices are also seen as socially shared, bundled with other practices, and embedded in social structures and processes. Practices are durable entities that persist over time; true practice change would hence entail durable intervention impacts. Our paper qualitatively investigates the long-term effects (2018–2023) of a practice-based living lab intervention that aimed to influence laundry and heating practices in Finnish households. We compare how the new or changed practices of 21 households, learned during the intervention, have persisted through societal changes (i.e., the Covid pandemic and the energy crisis), and whether these new or changed practices helped households to deal better with these crises. In this way, we contribute to, and also reframe, the problem of evaluating long-term effects, and critically consider the persistence of small-scale interventions in practices.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 5","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-024-10231-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141106084","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 hotel industry's activities might be directed to ecological harms such as the diminution of usual resources, global warming, and the emission of various green hazards that lead to wildlife extinction and water, air, light, and industrial pollution. The hotel business can become more environmentally friendly by utilizing employee green service recovery performance to determine which issues are environmentally friendly or unfriendly and are motivated by eco-friendly dedication and sustainable human resource management (GHRM) practices. GHRM encourages employees to be committed to the environment and act sustainably, enabling hotels to enhance their environmental sustainability. The key benefit of this research is to make it easier to understand how integrating GHRM practices improves environmental performance by increasing employees' commitment and behavior in an environmentally friendly manner. The modern study aimed to inspect and assess the effect of green intellectual capital and green commitment on environmental performance with the assistance of employees and managers working in hotels in India. It also investigates how green management of human resources affects how environmentally responsible hotels are. Moreover, Structural Equation Modeling (SEM) will be implemented to continuously evaluate any proposed interlinkages between the latent construct. Empirical findings have revealed that managing sustainable human resources improves employees' commitment to the organization, their environmentally responsible conduct, and the environmental performance of hotels.

Many private and public organisations support and promulgate this view. It accords with a stream of academic literature which suggests that the under-adoption of energy efficiency measures is a paradox indicating market failures and economically irrational behaviour by property owners. This paper offers cost–benefit analyses of 44 case study scenarios to test whether deep renovation in Germany pays back in monetary terms. These include both specific buildings and Germany-wide averages of classes of buildings. It uses current construction, finance and energy costs, and takes account of inflation, discount rates and opportunity costs. None of the scenarios are economically viable in monetary terms, and the average payback after 25 years is around 22.5%. Sensitivity analyses suggest payback would only be achieved using improbable parameter values.

Our findings reveal a diverse mix of policies targeting residential building decarbonization in all three regions. While the EU and China have long-established diverse policy instruments, India's building energy efficiency policies are relatively recent and limited. Detailed analyses of building energy codes, information disclosure, and financial incentives expose variations in ambition, scope, and implementation, even with shared policy instruments. Significant advancements in building energy codes, particularly in stringency and compliance checks, are evident in the EU and China. Conversely, India faces a notable obstacle with limited adoption of residential building energy codes, impacting its journey towards net-zero. The EU leads in building energy labelling policies, while China and India encounter various challenges hindering widespread implementation. Financial incentives across the three regions predominantly take the form of subsidies, potentially straining public budgets.

Very sophisticated models, which decision-makers are often unfamiliar with, are typically used to provide such assessments for large and complex systems.

A model is best known to its developers, who, therefore, need to be contracted to estimate the effects of the proposed policies. This takes time and money, yet leaves the credibility of the results questionable in countries with a limited culture of cooperation between decision-makers and a modeling community. One possible, yet partial, solution is to use an ensemble of models. Another option is to use a set of compact meta-models to address specific policies and measures; the parameters of such compact models can be assessed using other, large and complex, models. Decision-makers can run these simple compact models on their own to make policy dialogue more operational and to have more confidence in the results. This paper presents one such model, which consists of 95 compact sub-models designed to outline comprehensive energy efficiency programs, along with the results of its pilot application for an illustrative set of policies.
