Smart life and sustainable development: a comparative analysis on energy and water efficiency in China and the EU

Smart life relies on huge volumes of data analysis, which makes data centers become important infrastructure in smart city areas. Nowadays, data centers are constructed in many countries and have become increasingly large electricity consumers. The consumption of electricity is caused not only by the servers of data centers but also by the cooling systems. Meanwhile, data centers also demand water - cooling methods, which result in water consumption. As for sustainable development, water and energy consumption are huge challenges. Laws and rules are necessary for utilizing efficiently relevant sources. This paper will analyze China and the European Union (EU) as two examples of jurisdictions to compare how the governments regulate the construction of data centers to implement the thrift of electricity and water. In China, provinces and cities established diverse regulations based on their different natural and climate conditions, thus there is not a uniform model for the implementation in the country. In the EU, the amendment of Energy Efficiency Directive seeks to establish common policies. The difference of rules in these two jurisdictions reflects that China and the EU have their own principles and objectives: China attempts to balance the demand of developing smart city infrastructures and the consumption on natural resources, but the EU has strong ambition on low carbon emission in the whole Union. However, the two jurisdictions still have a common goal to maximize the efficiency of water and electricity consumption which is a fundamental issue for accelerating the transition towards sustainability.

The role of environmental knowledge, policies and regulations toward water resource management: A mediated‐moderation of attitudes, perception, and sustainable consumption patterns

AbstractWater is the lifeblood of our Earth, and sustainable water consumption is the key to preserving this scarce resource for future generations and upholding environmental sustainability. In this study, we investigate the relationship between environmental knowledge (EK), environmental policies and regulations (EPR), attitudes toward water resource management programs (APWRMP), perceived water quality (PWQ), and sustainable consumption (SC), enriching the existing literature by integrating the theoretical framework of the theory of planned behavior (TPB) alongside water management program (WMP) concepts. This integration forms a comprehensive model clarifying the influences on SC. Furthermore, this study investigates these relationships within the specific context of select regions in China, addressing a geographical gap in the current literature. With a sample size of (N = 336) participants, we employ partial least squares structural equation modeling (PLS‐SEM) to explore the complex relationships within the proposed model. The finding confirms the hypothesized associations, validating the substantial positive impact of EK and EPR on APWRMP and SC. Additionally, we observe that PWQ notably strengthens the link between the perception and attitude of villagers toward SC of water. Our study explains the multifaceted dynamics underlying individuals' behavior and attitude in making decisions concerning sustainable water consumption.

A taxonomy of demand management strategies for sustainable water consumption in urban households

ABSTRACT Excessive urban household water usage is a pressing global issue faced by many cities. This study aims to develop a concise yet encompassing taxonomy of water demand management strategies, offering a clear and organized framework that enables comparison and evaluation of strategies, informs policy and decision-making, and fosters an interdisciplinary approach to water demand management research. An analytical literature review using grounded theory and hermeneutics was conducted to find key concepts and constructs, identify relationships among them, and synthesize these elements into a coherent framework. The resulting taxonomy presents a classification of demand management strategies into five categories: Psychological, Educational-Communicational, Technological, Economical, and Coercive-Legal.

The interlinkage between land resources, food, water, income, and sustainable environment: Evidence from China's economy with COP27 perspective

AbstractChina, the most populous country across the globe, has emerged as one of the biggest economies; however, regarding food production, water, uplifting the income level, and attaining environmental sustainability, the policymakers are still concerned. China's government has worked immensely on eradicating poverty through increasing food production, ensuring access to clean water, and using land resources. Similar steps are taken about environmental protection. In this regard, China needs more empirical evidence to tackle such an environmentally destructive issue and sustainable natural resource use. The present study investigates the environmental Kuznets curve (EKC) while considering the importance of natural resources, food production and export, and water productivity in environmental quality. This research also explores the impact of tourism, energy use, and renewable energy output on carbon emissions in China during 1990–2021. This research authenticates the variables' stationarity and the long‐term equilibrium relationship between the study factors using the pre‐estimation diagnostic approaches. This study employed several parametric approaches and revealed that the EKC paradox is invalid in the case of China and vice versa in the presence of natural resources and food and water variables. Natural resources are the key hazard in attaining a sustainable regional environment and development. By contrast, increased economic growth and energy consumption also enhance the country's pollution level. In distinction, renewable electricity output, tourism industry, food production, and food export are the substantial drivers of attaining COP27 targets. Based on the study findings, this research recommends enhancement in sustainable food production and water management, improved production and consumption of renewables, reduced consumption of outdated energy, sustainable use of non‐renewable resources, and facilitated tourism across the country.

Striving for Sustainability: A Study of Water Consumption Behavior of Households in Lahore Division

Amid the escalating global water scarcity concerns, exacerbated by increasing demand characterized by unsustainable water consumption practices, this study addresses the imperative need to identify the factors that promotes the sustainable water consumption behavior among households. Our research builds upon the theoretical premises of the Theory of Planned Behavior (TPB), proposing a unique model that incorporates consumers’ water-saving preferences as a moderating factor to address the intention-behavior gap. In order to accomplish the proposed study objective, we approached 1552 households living in the residential premises of Lahore Division. We applied Partial Least Square – Structural Equational Modelling (PLS-SEM) to empirically analyze the results. Our research reveals that consumer’s sustainable water consumption intention and water saving preferences are important factors that promotes the sustainable water consumption behavior among the households. Moreover, the study unveils the moderating role of these preferences in reinforcing the relationship between intention and behavior, effectively bridging the intention-behavior gap. Additionally, our research identifies the indirect influence of consumers’ water-saving attitudes and perceived behavioral control on shaping sustainable water consumption behavior. Importantly, the study demonstrates a substantial improvement in the predictive accuracy of TPB with the inclusion of water-saving preferences as a moderating factor. These insights hold significant implications for devising interventions to promote sustainable water consumption behavior among households.

A segmentation approach to understanding water consumption behavioral patterns among households in Saudi Arabia for a sustainable future

Urban water consumption has significant implications for both human welfare and the environment, especially in arid regions. In Saudi Arabia, where 60% of the urban water supply relies on energy-intensive desalination processes, the average per capita water consumption rate of 300 L/day is one of the highest worldwide. This study investigates potential behavioral patterns in residential water consumption among households in Saudi Arabia. A segmentation approach is employed to classify residents into clusters and evaluate their potential water consumption behavioral patterns. Data from 618 households were collected via a structured questionnaire and analyzed using descriptive statistics, principal component analysis (PCA), and cluster analysis (CA). Participants were categorized into six segments based on the relationship between their behaviors and water consumption derived from the factor analysis. The outcomes of PCA and CA analyses indicate a relationship between respondents’ socio-demographic factors and their potential behavioral patterns in residential water consumption. The findings highlight that education, household size, income, housing type, age, and nationality, in increasing order of significance, are the key factors influencing household water consumption and conservation tendencies. The paper concludes that comprehending residential water consumption patterns is crucial for effective interventions, social marketing strategies, and communication campaigns for behavioral changes. The study can inform water conservation policies and programs that promote sustainable water consumption practices, benefiting agencies, policymakers, and scholars in the water sector.

Turning the invisible into the visible: exploring consumers’ perceptions towards sustainable water consumption

PurposeThis study aims to elaborate on the interface between water scarcity and consumption and, specifically to focus on, how consumers’ perceptions and views towards (un)sustainable water consumption can inform the development of sustainable water practices and environmental policies.Design/methodology/approachA qualitative methodology was adopted, consisting of 34 in-depth interviews with consumers, in four cities in the United Kingdom (UK). The semi-structured interviews sought to examine sustainable water consumption practices in more depth within an unexplored context, and secondary data were also used to explore the phenomenon in more depth.FindingsThe findings provide novel theoretical and empirical insights around the invisibility and imperceptibility of (un)sustainable water consumption. The findings suggest how interdisciplinary and collaborative practices can enhance more responsible and sustainable consumption of water resources in the UK.Practical implicationsThe study can inform marketing strategies on community engagement with localised water sustainable actions and encourage policymakers to develop concrete marketing communications and increased public awareness regarding water scarcity.Social implicationsConsidering the slow growth of water scarcity, the findings can prompt marketing scholars to explore similar phenomena, within seemingly unaffected countries, urban centres, industries and marketplaces.Originality/valuePrevious studies focused on the measurement of household water consumption in the water-scarce context of the Southern Hemisphere. Challenging geographical perceptions of water shortage, this study focuses on the UK and highlights how the multidimensional, finite and invisible nature of water consumption requires collaborative efforts in tackling water scarcity.

Barriers and Motivators of Household Water-Conservation Behavior: A Bibliometric and Systematic Literature Review

Water scarcity, aggravated by growing demands, represents a significant challenge for humanity. Promoting household sustainable water-consumption behaviors has become vital. The Community-Based Social Marketing (CBSM) framework stands out among many strategies to promote water conservation. However, many interventions in this domain often neglect significant theoretical insights, leading to gaps in addressing key social and contextual drivers of behavior. This study conducts a systematic and bibliometric literature review aimed at identifying determinants underlying household water-conservation behaviors. This review encompasses 155 papers published from 1984 to early 2023. Our findings show that this is a highly multidisciplinary field of study with a marked increase in research attention discerned post-2010, particularly from water-stressed regions. Furthermore, our findings also reveal an often-overlooked integration of guiding theories and an over-reliance on self-reported measures in prior research. Factors such as attitude, perceived efficacy, emotions, and habits emerge as pivotal in understanding water conservation. However, while attitudes have been extensively analyzed in previous research, the other factors deserve greater attention from researchers. Inconsistencies in demographic predictors further hint at potential moderating roles. This paper offers valuable insights for designing effective household water-conservation interventions through a social marketing lens.

An integrated approach to water conservation: fuzzy logic assessment of water tariffs in Abu Dhabi Emirate’s residential sector

BackgroundAbu Dhabi, a part of the United Arab Emirates, is situated in an arid region where water scarcity is a significant concern. The residential sector in Abu Dhabi consumes a large portion of the available water resources, leading to a critical need for effective water management strategies. This study aims to understand the relationship between water tariffs and water consumption in the residential sector in Abu Dhabi. It employs an integrated fuzzy logic model, a form of artificial intelligence, to assess the impact of water tariffs on water consumption. The model includes variables such as water tariffs, the level of water awareness, the level of water behavior, and the level of technology use. The objective of these variables is to evaluate their impact on the water-saving index, which represents the ratio of daily water consumption per capita in Abu Dhabi to the global average.ResultsThe findings of this study, based on a survey measuring the level of water awareness, behavior, and technology use, revealed a potential strategy for reducing water consumption in Abu Dhabi’s residential sector. It was observed that increasing water tariffs, while maintaining current levels of water awareness, behavior, and technology use, could lead to a reduction in water consumption. However, it was also found that the impact of further tariff increases on water conservation diminishes after a certain threshold, indicating the necessity of a balanced approach in tariff adjustment. Interestingly, the study also highlights that Abu Dhabi residents demonstrate high levels of water behavior and technology use, indicating a positive trend toward water conservation.ConclusionsThis study emphasizes the importance of increasing water awareness among Abu Dhabi residents as a means to foster sustainable water consumption practices. While water tariffs can contribute to reductions in water consumption, the effects tend to decrease beyond a certain point. Therefore, a comprehensive approach involving water tariffs, increased water awareness, and the adoption of water-saving technologies may be the most effective strategy for water conservation. The insights from this study extend beyond Abu Dhabi and offer valuable guidance for addressing water conservation challenges worldwide. It highlights the importance of adopting a multi-faceted approach in water management, and the potential for such strategies to have international relevance in the pursuit of sustainable water consumption.

Implications for sustainable water consumption in Africa by simulating five decades (1965–2014) of groundwater recharge

Groundwater stands as a vital water resource for both present and future generations in Africa. This underscores the importance of examining the sustainability of current groundwater consumption across the continent, along with its capacity to fulfill the current human and essential environmental water needs. Groundwater sustainable yield is a suitable indicator for assessing groundwater sustainability but has not yet been quantified properly across Africa. A thorough quantification of groundwater sustainable yield necessitates a profound comprehension of the spatio-temporal fluctuations in surface hydrology, groundwater recharge, environmental flow, and sectoral water use. In this study, high spatial resolution (10 km) land surface hydrology was simulated for five decades (1965–2014) across Africa by the Community Land Model version 5 at half-hourly time step and aggregated to monthly and annual temporal resolutions. Then, groundwater recharge and environmental flow were quantified based on the water balance approach for the whole continent. Finally, by including African sectoral water use data available for four decades (1971–2010) we obtained the long-term average of groundwater sustainable yield. Based on extensive simulations of long-term land surface hydrology, we discovered that the groundwater system in Africa experienced an average annual recharge of 57.8 mm yr−1 (with a standard deviation of 110.8 mm yr−1 serving as an indicator of spatial variability), corresponding roughly to an annual recharge volume of 1793.6 km3 yr−1. Furthermore, our analysis revealed that the entire continent possesses an annual average potential sustainable yield (with standard deviations) of 4.5 mm yr−1 (10.2), 20.6 mm yr−1 (42.9), and 37.3 mm yr−1 (75.7) under conservative, optimum, and suitable water consumption scenarios, respectively. This calculated annual groundwater sustainable yield corresponds to 141.9 km3 yr−1, 643.1 km3 yr−1, and 1160.5 km3 yr−1 for the conservative, optimum, and suitable scenarios, respectively. Furthermore, the calculated sustainable yield volume is contrasted with the total water storage figures documented for 50 countries throughout Africa. The outcomes illustrate that our calculated annual sustainable yield equates to roughly 0.02%, 0.1%, and 0.17% of the reported groundwater storage across the entire continent. Based on the estimated long-term average sustainable yield and the reported total water storage at the national level, our conclusion is that the accessible groundwater resources could potentially satisfy the current water requirements of both humans and the environment in African countries. This study offers the first model-based estimation of groundwater availability across Africa, potentially serving as a catalyst to inspire further progress toward adopting more sustainable approaches to groundwater usage on the continent.

Investigation of sustainable water consumption behavior within the framework of value belief norm

Investigation of sustainable water consumption behavior within the framework of value belief norm

Engineering Sustainable Water Consumption in the Western Part of the U.S. Casinos

In recent years the frequency of the term sustainability has increased in both literature and pop culture, specifically regarding the environment. With Casinos utilizing hundreds, sometimes thousands, of gallons of water daily, the sustainability of their methods is often questioned. With the rise in innovations, existing studies tend to be outdated and usually lack content about initiatives made by engineers in sustainable systems, showing the need for research analyzing these gaps. This study defines sustainability according to engineers both working in the field and retired, as well as their insight on the efficacy of current sustainability initiatives in casinos. With a total of 6 interviews, this paper defines sustainability as the utilization of resources without jeopardizing the future generation’s ability to utilize the same resources. It is uncovered how water is withdrawn from Lake Mead and most, if not all, is restored through the use of a credit system (defined in this paper). Plants across the valley ensure water is adequately cleaned and recirculated in Lake Mead to ensure Vegas’ thus far outstanding credit is maintained. Recent laws have been passed completely banning the future construction of golf courses or long landscapes for sustainability. Casinos are under the same scrutiny and regulation of water consumption as residential consumers; they are required to limit landscaping and cooling systems that could potentially expend water in a way that cannot be reclaimed. This paper explains the effectiveness of water consumption procedures in Casinos to combat water depletion in the Las Vegas Valley.

A Content Analysis of Architectural Atmosphere Influencing Mindfulness through the Lens of Instagram

Mindfulness is a psychological construct that enhances sustainable behaviors, environmental behavior, environmental consumption, mindful consumption, and water and energy sustainable consumption. The state of mindfulness can be affected by the determinator of the physical environment as architecture via the architectural atmosphere. The previous studies show that the discrete areas of knowledge between architecture and mindfulness are still widely unknown. However, image-centered social media platforms such as Instagram seem to be able to provide big data for studying people’s perceptions of architecture. Thus, this study aims to describe the concept design and characteristics of architectural atmosphere in architecture images tagged mindfulness posted to Instagram. A coding framework developed from a previous systematic literature review was conducted for this content analysis. A total of 354 architectural images were screened, coded, and analyzed by five architects. The results highlight that the Japanese traditional architecture (59.20%) looks to be the most architectural atmosphere concept that influences mindfulness, following by Biophilic Design (33.05%), and Buddhist contemplative space (20.06%). In addition, it was found that the most common architectural atmosphere characteristic fostering mindfulness performed calm space (73.58%), focus object (54.45%), concrete material (85.71%), hue color (78.17%), hard light and shadow (78.98%), and view with a tree (60.11%).

Responsibility for sustainable water consumption in the global supply chains

Freshwater, a limited natural resource, is unevenly distributed worldwide; this limited availability necessitates the virtual water trade in global supply chains, which may induce freshwater overconsumption (beyond carrying capacities). The dependency on remote water resources is imperceptible and barely recognized by consumers indirectly inducing water consumption. Here, we highlight the significance of remotely induced water consumption through supply chains and considerations for assessing and managing the sustainability of water resources through a case study of the Japanese national water footprint. The blue water consumption induced by the Japanese final demand (53.2 Billion m3) is approximately three times the volume saved through virtual water trade. For the compatible achievement of global and local sustainability of freshwater use, the hotspots in the global supply chains must be identified by considering three additional aspects in parallel, i.e., the concentration of overconsumption, pressure of overconsumption, and proportion to the local total overconsumption amount.

Sustainable water consumption and water‐saving behaviours: A review of consumers' environmental and economic concerns in Turkey

AbstractWater, which plays an important role in human life, has been depleted as a result of changing consumption patterns, climate change and increasing population, and water scarcity has emerged as one of the most pressing issues facing the world in the coming years. One solution to this problem is to make more efficient and sustainable use of existing water resources. In this context, the study aims to investigate the effects of consumers' environmental and economic concerns on sustainable water consumption behaviour, as well as the mediating role of water‐saving behaviour in these effects. For this purpose, it was discovered that environmental and economic concerns have positive effects on sustainable water consumption behaviour as a result of an analysis of data collected from 591 consumers in Turkey via the online survey method; it was determined that environmental concerns have no effect on water‐saving behaviour, whereas economic concerns have a positive effect on water‐saving behaviour. According to the findings of the mediation analysis, water‐saving behaviour only serves to mediate the effect of economic concerns on sustainable water consumption behaviour.

Novel Furrow Diking Equipment-Design Aimed at Increasing Water Consumption Efficiency in Vineyards

Productivity in viticultural practices is highly dependent on seasonal availability of rainfall and the efficiency of soil and water conservation strategies. Sustainable water consumption has been regarded as a business, social, and environmental responsibility, since resource availability becomes more challenging. The present research evaluates a new agricultural equipment design, employed in furrow compartmentalization works, with the aim of improving the efficiency of rainwater storage in the soil, reducing the runoff and the erosion on sloping soils. The newly developed equipment operates on the basis of a rigid memory and employs the cam-tappet mechanism, known for its high customization potential. The system functionality has been improved by integrating enhanced hoe shapes, adapted for the demanding working conditions encountered in vineyards. The evaluated performance indicators showed an increased up to 7% of the water storage effectiveness, while the micro-basins construction performance improved by 10%. The furrow diking phase is integrated into the weeding works, and recorded low additional fuel consumption of only 3–5%, being appreciated by farmers due to its constructive simplicity. As a result, the equipment has shown a significant application potential to increase deep water storage in vineyards and reduce the negative impacts of climate change on agriculture.

Integrated SWAT-MODFLOW Modeling-Based Groundwater Adaptation Policy Guidelines for Lahore, Pakistan under Projected Climate Change, and Human Development Scenarios

Urban aquifers are experiencing increasing pressures from climate change, land-use change, and abstraction, consequently, altering groundwater levels and threatening sustainable water availability, consumption, and utilization. Sustainability in such areas requires the adaptation of groundwater resources to these stressors. Consequently, this research made projections about future climate, land use, and abstraction, examines how these drives will affect groundwater levels, and then proposes adaptation strategies to reduce the impact on Lahore’s groundwater resources. The objectives are achieved using an integrated modeling framework involving applications of Soil Water Assessment Tool (SWAT) and MODFLOW models. The results indicated a projected rise in Tmin by ~2.03 °C and Tmax by ~1.13 °C by 2100 under medium (RCP 4.5) and high-end (RCP 8.5) scenarios, respectively. Future precipitation changes for mid, near and far periods are projected to be −1.0%, 25%, and 24.5% under RCP4.5, and −17.5%, 27.5%, and 29.0% under RCP8.5, respectively. The built-up area in the Lahore division will dominate agricultural land in the future with an expansion from 965 m2 to 3716 km2 by the year 2100 under R1S1 (R2S2) land-use change scenarios (significant at p = 5%). The future population of the Lahore division will increase from 6.4 M to 24.6 M (28.7 M) by the year 2100 under SSP1 (SSP3) scenarios (significant at p = 5%). Groundwater level in bult-up areas will be projected to decline from 185 m to 125 m by 2100 due to increasing groundwater abstraction and expansion in the impermeable surface under all scenarios. In contrast, agricultural areas show a fluctuating trend with a slight increase in groundwater level due to decreasing abstraction and multiple recharge sources under combined scenarios. The results of this study can be a way forward for groundwater experts and related institutions to understand the potential situation of groundwater resources in the Lahore division and implement adaptation strategies to counteract diminishing groundwater resources.

An Approach for Water and Energy Savings in Public Buildings: A Case Study of Brazilian Rail Company

Water scarcity is a current problem in many parts of the planet and there is a worldwide concern about water availability to meet future water demand. In countries like Brazil, where most of the electricity is produced by hydroelectric power plants, water scarcity directly impacts energy production. The water–energy nexus is directly related and impacted by CO2 emissions and its climate consequences, which calls to a broader approach: energy–carbon–water nexus. In this context, the Sustainable Water and Energy Consumption (SWEC) Program was developed to mitigate water and energy supply problems in a railway company in Brazil. The actions took place in four main areas: (a) users conscientization, (b) consumption diagnosis, (c) indicators for evaluating water and energy consumption, and (d) evaluation of implementing alternative cleaner water and energy sources. The per capita consumption of water and energy were reduced by 10% and 19%, respectively. Permanent results were achieved by the SWEC Program, such as the acquisition of two photovoltaic systems with a total capacity of 96.5 kWp. The investment made provided an average monthly reduction in energy consumption of 56% in 2022. This work contributed to the UN Agenda 2030 and the findings may help companies and industries, and other institutions, such as universities and schools, to improve their water and electricity consumption.

Global water consumption impacts on riverine fish species richness in Life Cycle Assessment

Reduced river discharge and flow regulation are significant threats to freshwater biodiversity. An accurate representation of potential damage of water consumption on freshwater biodiversity is required to quantify and compare the environmental impacts of global value chains. The effect of discharge reduction on fish species richness was previously modeled in life cycle impact assessment, but models were limited by the restricted geographical scope of underlying species-discharge relationships and the small number of species data. Here, we propose a model based on a novel regionalized species-discharge relationship (SDR). Our SDR-based model covers 88 % of the global landmass (2320 river basins worldwide excluding deserts and permanently frozen areas) and is based on a global dataset of 11,450 riverine fish species, simulated river discharge, elevation, and climate zones. We performed 10-fold cross-validation to select the best set of predictors and validated the obtained SDRs based on observed discharge data. Our model performed better than previous SDRs employed in life cycle impact assessment (Kling-Gupta efficiency coefficient about 4 times larger). We provide both marginal and average models with their uncertainty ranges for assessing scenarios of small and large-scale water consumption, respectively, and include regional and global species loss. We conducted an illustrative case study to showcase the method's applicability and highlight the differences with the currently used approach. Our models are useful for supporting sustainable water consumption and riverine fish biodiversity conservation decisions. They enable a more specific, reliable, and complete impact assessment by differentiating impacts on regional riverine fish species richness and irreversible global losses, including up-to-date species data, and providing spatially explicit values with high geographical coverage.

How does sustainable water consumption in the shower relate to different dimensions of perceived well-being? Empirical evidence from university students

ABSTRACT Water scarcity is already a worrying issue and it is predicted to get worse in the future. This creates an imperative to use water efficiently and sustainably. In the domestic sphere, one of the main uses of water is showering, not only for hygiene reasons but also as a wellness activity. In order to gain insight into the implications of sustainable shower use, in this paper we analyse the relationship between subjective well-being and water consumption in the shower. We aim to answer the following questions: 1) How does shower water consumption relate to subjective well-being, 2) Does this relationship differ depending on showering habits (time spent in the shower, and number of showers per week), and 3) Does this relationship differ depending on the season (winter and summer). The dataset contains information on 937 students from different disciplines at the University of Granada, Spain. The different interpretations of subjective well-being considered are life satisfaction, affect, and vitality. Results suggest that there is a negative relationship between water consumption and subjective well-being, in line with the literature that identifies a well-being dividend from green behaviour (being pro-environmental helps the environment and increases happiness). All subjective well-being dimensions are negatively related to time spent in the shower, regardless of the season. In contrast, the frequency of showering is not significantly related to well-being. Therefore, it appears that higher water consumption does not translate into higher perceived well-being, indicating that there is no conflict between efficient shower water use and individual well-being.
