Sustainable Energy Planning and Management with cooking and maritime transport electrification, household energy savings and heating sector integration
Full text linkThis 43rd volume of the International Journal of Sustainable Energy Planning and Management presents contemporary research within the diverse field of energy planning. The issue starts with analyses of an Indian programme targeting the replacement of fossil fuel-based stoves with induction stoves. Another electrification analysis targets maritime transportation and floating offshore charging stations. Third, analyses are presented regarding the potential impacts of household energy savings in Iran, and whether to optimally use savings for unmet demands in industry or for export – or indeed to lower production correspondingly. Two Hungarian studies focus on a comparison of using heat atlas and using measured data for heat planning and on the feasibility of using individual heat pumps as flexibility provider for the electricity system. Taking a Danish case as a starting point, the role of the heating system in the overall energy system transition is analysed and lastly, a study review the literature on city energy planning approaches
Multivariate Forecasting of Electricity Consumption for Sustainable Energy Planning
Full text linkForecasting accurate consumption of electricity is crucial for energy security of a rapidly grown region. Prior study proves that there is a positive relationship between electricity consumption, population and economic growth. Nevertheless, only a few have applied the multivariate model within a regional context for the long-term electricity forecasting. This study tries to bridge the gap in forecast reliability by using machine learning to support regional sustainable energy planning in the Lampung Province. The methodology includes data preprocessing, integration, and cleaning, and model training and validation using time-series data. The Vector Autoregressive (VAR) was employed to predict electricity consumption from 2024 to 2030 based on historical data from 2010 to 2023. The model demonstrated a robust predictive performance, with a low MAPE of 0.57%, RMSE of 37.74, and a high R² value of 0.998. This instills confidence in the findings of the research and the future use of the VAR for electricity forecasting. The model suggests that the trend of energy consumption in Lampung Province is continuously increasing. The study also stresses the need for renewables to meet future electricity needs, ensuring energy infrastructure tackles socio-economic growth and the energy transition agenda with regard to the development of Lampung Province
Establishing Critical Elements of Energy Management for Sustainable Campus Development
Full text linkA comprehensive energy management guideline tailored to higher education institutions in Malaysia is essential for advancing sustainable campus development. As energy consumption rises due to infrastructure growth and increasing student populations, existing sustainable campus tools often fall short in fully integrating key energy management elements. This research focuses on identifying critical energy elements that contribute to campus sustainability. A review of 23 international sustainability frameworks, including STARS, Green Mark, GBI, and UI GreenMetric, revealed that most tools lack a holistic approach to energy management. A framework with 11 essential energy elements is proposed, covering both technical (retrofitting, building envelope, efficient equipment, mechanical systems, and renewable energy) and management aspects (organizational structure, energy policy, planning, energy auditing, reporting, and awareness). UI GreenMetric was selected as the baseline reference due to its alignment with the Malaysian university context. A structured questionnaire was applied in a case study at Universiti Malaysia Sabah to evaluate the relevance of each element. Judgmental sampling targeted. Data were analyzed using descriptive statistical methods including frequencies and mean scores. The findings establish a set energy management elements and highlight the importance of combining critical technical and management aspects to support sustainable energy practices across Malaysian higher education campuses
Sustainable land use planning based on geoecological potentials: Geotope models as a new planning tool in landscape transformations
No full textDenne artikel undersøger, hvordan jordressourcens egenskaber kan danne grundlag for en mere differentieret og bæredygtig arealplanlægning i Danmark. Artiklen indledes med et litteraturstudie, der kortlægger potentialer og udfordringer for rumlig planlægning i landzonen.
Med udgangspunkt i udviklingen af en ny jordressourcemodel – geotopmodellen – introduceres derefter en ny tilgang til rumlig planlægning, hvor landskabet opdeles i funktionelle enheder, der deler biofysiske karakteristika og opfører sig ens under sammenlignelig arealanvendelse. Modellen gør det muligt at vurdere arealers potentiale på tværs af anvendelser inden for landbrug, skovbrug, naturforvaltning og vandindvinding.
Ved hjælp af et nyt planværktøj (LandAllocate) er det afprøvet, hvordan viden om jordressourcens potentialer kan indgå i transparente, datadrevne og lokalt forankrede beslutningsprocesser som eksempel på en ny tilgang til planlægning for bæredygtig arealanvendelse ud fra jordressourcens potentialer. Det diskuteres hvordan geotoper kan fungere som meningsfulde planlægningsenheder og skabe en fælles referenceramme for samarbejde mellem fx. myndigheder, lodsejere og civilsamfund. Der argumenteres for, at modellering af jordens ressourcer er en mulig platform for datadrevne jordreformer, hvor arealtransformationer kan planlægges, igangsættes og evalueres med afsæt i landskabets permanente egenskaber og dets langsigtede kapacitet for understøttelse af arealanvendelse.We here investigate how improved information about the spatial distribution of land resources can form the basis for reforming and refining rural land use planning in Denmark. The article is introduced with a literature review identifying challenges and potentials for spatial planning in rural Denmark, in the context of land use reform initiatives.
Based on the development of a new land resource model – the geotope model – a new approach to spatial planning is introduced and discussed. The new approach to planning divides the landscape into functional units that share biophysical characteristics and behave similarly under comparable land use. In this way the model segments the landscape into ecologically meaningful spatial units for land management, delineated along vectors of maximum variation in conditions for land use. The model makes it possible to assess and compare the land use potential of rural land units across a range of discrete land uses, including agriculture, forestry, conservation, nature management, water extraction, etc.
Using a new tailormade planning tool (LandAllocate), we tested how knowledge about the potential use of land resources can be incorporated into transparent, data-driven and locally anchored decision-making processes, as an example of a new approach to planning for sustainable land use based on the potential of land resources. This was tested in two case studies in the Zealand region of Denmark. On this basis we discuss how the introduction of geotope land units may contribute to sustainable land use planning, by providing a spatial framework of ecologically meaningful planning units and through the creation of a common frame of reference for cooperation between land holders, land users, authorities, and civil society organizations. It is argued that high resolution modeling of functional land resources may hold the potential to act as a platform for data-driven land reforms, where land transformations can be planned, initiated and evaluated based on the permanent characteristics of the landscape and its long-term capacity to support land use
Multimodal metaphors in public service advertisements: Cross-cultural considerations
Full text linkThis study investigates the role of multimodal metaphors in public service advertisements (PSAs), focusing on their application across diverse cultural contexts to understand their impact on global communication. It explores how metaphors are structurally encoded through cognitive, visual, and textual formats, providing insights into their persuasive and communicative functions. Utilizing Lakoff & Johnson’s (1980) Conceptual Metaphor Theory, Forceville’s (2008) multimodal metaphor framework, and Trompenaars’ (1994; 2004) cultural dimensions, the research examines PSAs addressing global warming from both individualistic and collectivist cultural contexts. The analysis is based on a dataset of 100 global warming PSAs sourced from AdForum’s international advertising database. This selection ensures that the advertisements represent a range of effective communication practices across different cultural dimensions. The study is driven by two research questions: a) How is pictorial metaphor structurally encoded across cognitive, visual, and textual modes in PSAs produced in different cultural contexts? b) What intended messages do the PSAs imply, and how do pictorial metaphors and cultural elements contribute to their communicative function? The findings reveal: 1) PSAs from individualistic cultures tend to use straightforward, visually explicit metaphors, while PSAs from communitarian cultures favor more complex, implicit metaphors, reflecting cultural preferences for directness versus contextualization. 2) The intended messages of PSAs vary by cultural context, with individualistic cultures emphasizing personal responsibility through metaphors, while collectivist cultures highlight collective action and shared responsibility. These findings demonstrate how metaphors are tailored to resonate with cultural values, contributing to the fields of advertising, cross-cultural communication, and environmental advocacy.This study investigates the role of multimodal metaphors in public service advertisements (PSAs), focusing on their application across diverse cultural contexts to understand their impact on global communication.

Teaching Virtual Production in Higher Education: Lessons Drawn from the VPSN Research Project
Full text linkVirtual production (VP) are technologies and processes to combine digital environments with physical stages to create content for entertainment industries like cinema. As teachers in related areas, we aim to keep our students up to date with VP skills, as they grow in demand from creative industries, and harnessing them requires significant learning commitment and financial investment. This paper presents a research project, the Virtual Production Studio Network (VPSN), which is aimed at addressing the previous demand, by providing knowledge resources and training. Drawn results from these activities enforce the idea that VP is not a universal solution to shooting films, and given its financial requirements, cost-effective alternatives must be sought to sustain learning. Independently of these challenges, VP holds immense potential, therefore we will keep pursuing ways to integrate its knowledge and technology into our lectures to augment the students' readiness in this field
