Abstract

Purpose

This purpose of this paper is to address the problem of reducing energy consumption in existing buildings using advanced noninvasive interventions (NVIs).

Design/methodology/approach

The study methodology involves systematically developing and testing 18 different NVIs in six categories (glazing types, window films, external shading devices, automated internal shades, lighting systems and nanopainting) to identify the most effective individual NVIs. The impact of each individual NVI was examined on an exemplary university educational building in a hot climate zone in Egypt using a computational energy simulation tool, and the results were used to develop 39 combination scenarios of dual, triple and quadruple combinations of NVIs.

Findings

The optimal 10 combination scenarios of NVIs were determined based on achieving the highest percentages of energy reduction. The optimal percentage of energy reduction is 47.1%, and it was obtained from a combination of nanowindow film, nanopainting, LED lighting and horizontal louver external. The study found that appropriate mixture of NVIs is the most key factor in achieving the highest percentages of energy reduction.

Practical implications

These results have important implications for optimizing energy savings in existing buildings. The results can guide architects, owners and policymakers in selecting the most appropriate interventions in existing buildings to achieve the optimal reduction in energy consumption.

Originality/value

The novelty of this research unfolds in two significant ways: first, through the exploration of the potential effects arising from the integration of advanced NVIs into existing building facades. Second, it lies in the systematic development of a series of scenarios that amalgamate these NVIs, thereby pinpointing the most efficient strategies to optimize energy savings, all without necessitating any disruptive alterations to the existing building structure. These combination scenarios encompass the incorporation of both passive and active NVIs. The potential application of these diverse scenarios to a real-life case study is presented to underscore the substantial impact that these advanced NVIs can have on the energy performance of the building.

Abstract

Purpose

The purpose of this paper is to present a conceptual framework that provides insights into major environmental and organizational forces underlying greater levels of organizational responsiveness to the environmental sustainability imperative by a growing number of firms, worldwide.

Methodology/approach

The paper is conceptual in its focus, and the proposed framework builds on extant literature from multiple literature streams.

Findings

Societal progress toward environmental sustainability is a shared responsibility of consumers, corporations, and the government at various levels. A potential avenue for societal progress toward environmental sustainability is fostering a macroenvironment that is conducive to the elimination of consumption certain products, reduction in consumption certain other products, and redirection of consumption of still other products from ecologically more harmful to ecologically less harmful substitute products (and relatedly, demand elimination, demand reduction, and demand redirection).

Research and practical implications

An implication for corporate sustainability responsibility is that firms while planning and formulating strategies for increasing their market footprint must also concurrently plan and formulate strategies for decreasing their environmental footprint. An implication for government sustainability responsibility is that even under conditions of high levels of commitment by a large and growing number of firms and consumers to engage in environmentally sustainable behaviors, in the absence of supporting infrastructure for engaging in such behavior, they may find it necessary to engage in environmentally unsustainable behaviors.

Originality/value

Issues relating to environmental sustainability have been the focus of a large body of recent research in a number of academic disciplines including marketing. A cursory examination of numerous articles published in scholarly journals on issues pertaining to environmental sustainability, and in the business press pertaining to the myriad environmental sustainability initiatives of firms worldwide is indicative of its growing importance.

Abstract

Purpose

The University of A Coruña (UDC) elaborated the SOSTAUGA project, aiming to reach a higher sustainable level of its water management. SOSTAUGA defined four priority points of action: the restoration of the natural courses on the campus; the adoption of an ecological sanitation model; the sustainable management of urban runoff; and the reduction of water consumption in university facilities and activities. This paper aims to present the methodology, the actions and the results related to the reduction of water consumption and the potential for the use of endogenous resources.

Design/methodology/approach

The agents involved were the senior management of the centres, the committees of the Green Campus, the scholarship students and the Office for the Environment. Several actions have been experienced: audit of water consumption in sanitary services; flow reduction in washbasin taps by means of valve adjustment (and repair of the valves when necessary); replacement of tap aerators with other more eco-efficient ones; replacement of faucets; introduction of dual-flush (DF) in cisterns; and information to users (eco-label).

Findings

Water audit reached 68% of the total number of washbasins and tanks in the UDC. Efficient aerator installation covered 16% of taps and valve adjustment covered the further 33.5% and provided flow reduction of 42%. Another 20% of valve units required repair. The current situation in toilets combines tankless flush valves and cisterns with single flush mechanisms. The introduction of DF mechanisms was assessed and proposed. The cost of these actions was very low, as evidenced by the investment return period while showing a high potential for user awareness.

Originality/value

Both from the environmental (water saving) and from the economic and social points of view, this study shows that similar projects aimed at the efficient and rational use of water are applicable to the universities and other public and private schools, with potentially positive results on sustainability and people awareness.

Abstract

Purpose

Ethical consumption is an integral component for the sustainable development in the world and is especially challenging in the Western consumer society. This research demonstrates that mindfulness, a Buddhism-based notion, is associated with two related and distinctive approaches of ethical consumption: refinement and reduction. It examines the psychological mechanisms underlying the effects of mindfulness on these two approaches of ethical consumption.

Design/methodology/approach

Self-report data were collected through an online survey with consumers from western societies (N = 523).

Findings

The findings show (1) that the significance of mindfulness on both approaches of ethical consumption and (2) that the contrast between the different mechanisms underlying them. Specifically, the mindfulness–consumption refinement link is fully mediated by connectedness-to-nature whereas the mindfulness–consumption reduction link is fully mediated by connectedness-to-nature and self-control. A series of supplementary studies further confirmed the proposed model.

Research limitations/implications

It demonstrates the multifaceted and complex nature of ethical consumption, which is positively associated with mindfulness but through distinctive psychological mechanisms.

Practical implications

The multifaceted and complex nature of ethical consumption and its underlying drivers need special attention. Mindfulness can be an effective means to boost ethical consumption behavior. Meanwhile, nurturing the sense of connectedness to nature and self-control capability facilitates the path-through of the positive impacts of mindfulness

Social implications

The findings can be adopted to enhance the effectiveness of mindfulness practice in promoting ethical consumption towards achieving the Sustainable Consumption goal, especially in the West.

Originality/value

The paper makes original contribution by conceptualizing two interrelated and distinctive approaches of ethical consumption and shows how mindfulness promotes both through different mediating pathways. Overall, this study paints a clearer picture how mindfulness relates to ethical consumption.

Abstract

Purpose

The purpose of this paper is to explore how members of an online alcohol reduction community learn, construct and engage in alcohol reduction consumption consistencies.

Design/methodology/approach

Blog data from 15 individuals participating in the online community of Hello Sunday Morning were collected and analysed. Informants also participated in a series of in-depth interviews to gain a self-reflective perspective of alcohol reduction action, activities and interactions.

Findings

The findings indicate learning of new alcohol reduction consumption consistencies occurs through three modes or learning infrastructures: engagement, imagination and alignment, enabling a collective sense of connection in the creation of new alcohol-related rituals and traditions, competency of practices and transmission of values and norms beyond the community.

Research limitations/implications

The results underscore the need for social marketers to recognise learning of alcohol reduction behaviour is continually negotiated and dynamically engendered through socially reproduced conditions, responses and relationships.

Originality/value

This study contributes to the transformational potential of social marketing situating behaviour change as a social interaction between actors within a dynamic market system.

Abstract

Purpose

The purpose of this paper is to outline efforts at the University of Johannesburg, a large metropolitan university in Gauteng province, to examine energy efficiency within the context of the green campus movement, through the analysis of electricity consumption patterns. The study is particularly relevant in light of the cumulative 230 per cent increase in electricity costs between 2008 and 2014 in South Africa that has forced institutions of higher education to seek ways to reduce energy consumption.

Design/Methodology/Approach

A quantitative research design was adopted for the analysis of municipal electricity consumption records using a case study approach to identify trends and patterns in consumption. The largest campus of the University of Johannesburg, which is currently one of the largest residential universities in South Africa, was selected as a case study. Average diurnal consumption profiles were plotted according to phases of the academic calendar, distinguished by specific periods of active teaching and research (in-session); study breaks, examinations and administration (out-of-session); and recesses. Average profiles per phase of the academic calendar were constructed from the hourly electricity consumption and power records using ExcelTM pivot tables and charts.

Findings

It was found that the academic calendar has profound effects on energy consumption by controlling the level of activity. Diurnal maximum consumption corresponds to core working hours, peaking at an average of 2,500 kWh during “in-session” periods, 2,250 kWh during “out-of-session” periods and 2,100 kWh during recess. A high base load was evident throughout the year (between 1,300 and 1,650 kWh), mainly attributed to heating and cooling. By switching off the 350 kW chiller plant on weekdays, a 9 per cent electricity reduction could be achieved during out-of-session and recess periods. Similarly, during in-session periods, a 6 per cent reduction could be achieved.

Practical implications

Key strategies and recommendations are presented to stimulate energy efficiency implementation within the institution.

Originality Value

Coding of consumption profiles against the academic calendar has not been previously done in relation to an academic institution. The profiles were used to establish the influence of the academic calendar on electricity consumption, which along with our own observation were used to identify specific consumption reduction opportunities worth pursuing.

Abstract

Purpose

The purpose of this paper is to quantify the possible interactions among the three European objectives in the horizon of 2020: the reduction of 20 per cent of greenhouse gas emissions (GHG); the saving of 20 per cent of the European energy consumption; and a share of 20 per cent of renewable energies in the overall energy consumption. Particular focus is, however, placed on the influence of the CO2 emission reduction targets and on their consequences on the carbon price in 2020.

Design/methodology/approach

In order to explore the interactions among the three European objectives and their induced effects, a number of scenarios are tested within a combination of two modeling tools: the POLES world energy model and ASPEN, an auxiliary model dedicated to the analysis of quota trading systems. With reasonable assumptions for the burden sharing among the member states, the energy efficiency objectives and the renewable energy targets are achieved using national quota systems in each European country (white and green certificate systems and their implicit prices), while the CO2 emission reduction is carried out within the European Emissions Trading Scheme (ETS) in line with the objective of 20 per cent emission reduction.

Findings

The paper shows, in particular, that the two quota policies (white certificates and green certificates) decrease significantly the European marginal emission reduction cost and consequently, the compliance costs for ETS participants. The high‐renewable target compliance cost could be reduced significantly if carbon price signal and energy saving policies are in place. The paper also shows that the sole carbon price signal has a limited influence for stimulating renewable energies and energy savings and thus concludes on the need for specific policies targeting these two areas.

Originality/value

This paper is a first attempt to comprehensively deal with the economic fundamentals of the 3D regulatory system proposed by the Commission for Energy and Climate and is of value in proposing a comprehensive approach of the economics of the “20/20/20” European policy.

Abstract

Purpose

The purpose of this paper is to asses the welfare and macroeconomic implications of three distinct degrowth strategies designed to reduce carbon emissions: penalizing fossil fuel demand, substituting aggregate consumption with leisure and disincentivizing total factor productivity (TFP) growth.

Design/methodology/approach

Using an environmental dynamic general equilibrium (eDGE) model that incorporates both green renewable technologies and fossil fuels in the production process, this study sets an emissions reduction target aligned with the goals of the Paris Agreement by 2050.

Findings

The results reveal that the conventional degrowth strategy, wherein a reduction in the consumption of goods and services is compensated with an increase in leisure, may entail significant economic consequences, leading to a notable decline in welfare. In particular, a degrowth scenario resulting from a decline in TFP yields the most pronounced reduction in welfare. Conversely, inducing a reduction in fossil fuel demand by fiscally inflating the price of the imported commodity, despite potential social backlash, exhibits noticeably less detrimental welfare effects compared to other degrowth policies. Furthermore, under this degrowth strategy, the findings suggest that a globally coordinated strategy could result in long-term welfare gain.

Originality/value

To the best of the authors’ knowledge, this is the first contribution that uses an eDGE model to evaluate the welfare implications of an additional degrowth strategy amidst the ongoing inertial reduction of carbon emissions.

Abstract

Purpose

The call for consumption reduction behavior has been getting more attention from scholars and practitioners. However, the consumption reduction often receives backfire from consumers because it does not follow the business philosophy of demand creation. Thus, this research dissolves this issue by using a holistic corporate social responsibility (CSR) approach regarding sustainable development.

Design/methodology/approach

A conceptual model was developed to represent the proposed relationships among the related variables. The current study employed an online survey to collect data from 341 international program students of three prominent universities in Ho Chi Minh City, Vietnam.

Findings

The findings indicate that the perception of the holistic CSR negatively impacts perceived corporate hypocrisy, triggering in turn brand credibility, resulting in brand advocacy and mindful consumption behavior.

Originality/value

This research forms a holistic CSR including economic, environmental and societal dimensions and proposes that the holistic CSR triggers brand advocacy and mindful consumption behavior representing consumption reduction behavior via the mediating roles of perceived corporate hypocrisy and brand credibility. These findings contribute to theoretical and managerial implications in CSR practices with the aim of consumption reduction.
