Terra infirma: On the base map in urban cartography and GIS

This article investigates the ways in which base maps are a fundamental, but under-recognised, starting point for planners, architects, cartographers and geographic information scientists in urban spatial planning and decision-making contexts. Focusing on the case study of a collaborative mapping project with the Wood Street Commons, an unhoused community in West Oakland, it contends that base maps create a cartographic terra infirma, fundamentally shaping the process of negotiations over urban space in ways that reinforce possessive logics and normalize property as central to the function of the city. Base maps do so by paradoxically absenting all people – with the effect of absenting the occupation of land by unhoused people, while shielding property owners from view while enacting their possession through infrastructure, parcel boundaries and land features. We argue this privileging inherent in the urban base map ultimately fuels a process of “unbecoming” ( Fraser, 2018 ) – a simultaneous invisibilizing and reproduction of spatial inequality – and in response, call for attention towards the politics of base maps from urban cartographers, planners, architects and spatial scientists alike.

Barriers to resolving institutional complexity in access-based service innovation

Access-based services (ABS) mobilize heterogeneous sets of actors, and failed collaboration among these actors can lead to service failure. This case study of a failed casual carpooling project (a form of peer-to-peer access-based service) demonstrates that actors struggle to collaborate when operating under differing institutional logics. When logics are incompatible, key factors can hinder tension resolution and ultimately doom an ABS project. These factors include an absence of effective orchestration, the imposition of a singular (contested) logic while silencing others, and the provision and dissemination of conflicting information. This case study highlights some of the reasons why ABS initiatives, such as casual carpooling, succeed or fail.

Taking first steps so that others can run – functions and limitations of governing the local energy transition

ABSTRACT Rising energy prices and fuel scarcity are exposing the volatility of our energy system and creating additional pressures to speed up the transition towards renewable energy using distributed production and integrated local grids. This raises the need for local governments to become more actively involved in energy governance by managing the transition of their energy systems and involving local stakeholders. However, the exact role of local authorities in steering this transition remains uncertain as they lack financial and administrative capacities and rely extensively on experimental innovation projects and external stakeholders. This paper therefore asks what functions local authorities exercise to govern the energy transition and under what conditions they can facilitate participation in and scaling of energy innovations. Drawing on the literature on experimental governance, the paper analyses four qualitative case studies of energy innovation projects run by local governments in Sweden, Belgium, the Netherlands, and the UK. It finds that local authorities can actively support innovation projects through funding and knowledge, convene between stakeholder groups, scale innovations through planning and promotional work, and use trial insights to advocate for policy change. However, their ability to exercise these functions is dependent on local stakeholder constellations and domestic policy conditions.

Managing Design Changes through Integrating Concurrent Engineering into the Architectural Design Process

This research aims to investigate the role of concurrent engineering (CE) towards managing design changes (DCs) during the architectural design process (ADP). To achieve this aim, a mixed research approach combining qualitative and quantitative methods was designed to accomplish four objectives. Firstly, the literature review investigated ADP, causes and impacts of DCs and CE. Secondly, three case studies of construction projects from Finland, China and Indonesia were collected and analysed to validate the identified causes and impacts of DCs and examine the role of CE towards managing DCs during ADP. Thirdly, a survey questionnaire was conducted with a representative sample of Architectural Design Firms (ADFs) in Egypt to assess their perception and application of CE as an approach for managing DCs during ADP. Based on the above, the research developed and validated a framework to manage DCs by integrating CE into ADP. Data analysis showed that the “Inability of clients and end-users to comprehend and explain the project requirements due to lack of technical knowledge” and “Inability of clients and end-users to accept advice and guidance” were ranked the highest influential causes of design changes (CDCs). In addition, the “Nature of the traditional procurement approach” and “Insufficient support from the senior management” were ranked the highest challenges of integrating CE in ADFs. These findings informed the research and helped in the development of the proposed framework, which represents a novel and creative synthesis that adds value to knowledge in a way that has not previously occurred.

Perancangan Tata Udara Menggunakan Metode Cooling Load Tempreture Difference (CLTD) Pada Studi Kasus Proyek X

This research is related to the design of air conditioning using the Cooling Load Temperature Difference (CLTD) method in the case study of Project X. One of the methods used is the Cooling Load Temperature Difference (CLTD) method. This method considers factors such as wet-bulb temperature, dry-bulb temperature, and air velocity to calculate the room cooling load. This research applies the CLTD method to a case study project in Jakarta with an air conditioning system in office buildings. This case study provides an example of the practical application of the CLTD method that is beneficial for practitioners in the field of air conditioning engineering. To implement the CLTD method, data from field studies such as room conditions, temperature, and humidity of the room and environment are needed. Next, calculations are made using the CLTD formula adjusted to the position of the sun in each room. The CLTD calculation results show that the highest sensible load is in the Boardroom, while the highest latent load is in the Conference Room. The design of the cooling system with the CLTD method shows optimal results and meets the requirements. The AC capacity calculated accurately and considering K4L factors results in an efficient, safe, and environmentally friendly cooling system.

Feasibility analysis of hybrid photovoltaic, wind, and fuel cell systems for on–off‐grid applications: A case study of housing project in Bangladesh

AbstractThis study investigates the viability of hybrid photovoltaic (PV), wind, and fuel cell (FC) systems for on‐grid and off‐grid operations for the Ashrayan‐3 housing project in Bangladesh, with an increased focus on sustainable energy solutions. Motivated by the issue of the delivery of proper and sustainable energy services to remote locations, we conducted an extensive analysis of load demand and found that an average daily demand of 46,176.65 kWh exists, with a peak load of 4852.8 kW. In this research, the HOMER software has been used to make a simulation of five different hybrid system configurations with differing mixes of renewable technologies. From the analyses, the systems based 100% on renewable resources suffer more initial capital costs, with a total net present cost increase of up to 20%, in comparison to conventional systems. On the other hand, the systems give much lower operational costs and cost of energies (COEs) of a minimum of $0.0253/kWh, reported from the on‐grid PV‐based system. On the other hand, the off‐grid PV–FC–wind turbine system showed a COE of $0.286/kWh, along with a decrease in CO2 emissions by about 15,000 kg/year, showing a 30% decrease, compared with on‐grid systems. The results form a basis for the conclusion that such hybrid renewable energy systems are both economically and environmentally feasible. They can reduce COEs by up to 70% in off‐grid systems. This proves that the quality of life and energy security in developing regions will be highly increased, supporting the goals of sustainable development.

Price disparities in the housing market vs. transportation costs for households. A case study of real estate development projects in Szczecin

Motives: Land situated on the outskirts of cities and even outside their borders is being seized for urban development, as well as for housing purposes. Properties in such locations are usually significantly cheaper than those located in the city centers. However, living in a suburban location often entails higher commuting, education, and entertainment costs. Therefore, the following question arises from a property buyer’s point of view: is it more economically advantageous to purchase more expensive property in a downtown district or a cheaper one located peripherally and incur higher transportation costs? Aim: The purpose of the study was to compare the transportation costs incurred by households in peripheral locations with the property price differentials between suburban and central city districts. Results: The study covered the city of Szczecin. Data for the study were obtained from public sources and analyzed with tools such as the payback period, simple rate of return, net present value (NPV) for 10 and 20 years, and internal rate of return (IRR) for 10 and 20 years. The results indicate that in certain cases, very high commuting costs might encourage potential buyers to consider the purchase of more expensive property in a central city location where these costs are significantly lower or not necessary.

Life cycle assessment of carbon emissions for cross-sea tunnel: A case study of Shenzhen-Zhongshan Bridge and Tunnel in China

Due to significant population concentration and capital influx in Guangdong-Hong Kong-Macao Greater Bay Area, the construction of cross-sea tunnels with significant consumption of various resources and materials, has been frequently witnessed. However, there is a lack of knowledge regarding how carbon emissions of cross-sea transportation infrastructure are generated across its life-cycle stages. This study proposes a life cycle assessment (LCA) approach for quantifying the carbon emissions and exploring the carbon reduction potentials with a case study of a world-renowned cross-sea tunnel project in Guangdong-Hong Kong-Macao Greater Bay Area. The results find that this project contributes approximately 849 kilotons CO2eq of carbon emissions with an emission intensity of 1.1 kilotons CO2eq per meter. The materialization stage is the largest contributor of carbon emissions (474.9 kilotons CO2eq), followed by service stage (248.3 kilotons CO2eq, accounting for 29.2 %). Some carbon emissions of raw materials can be offset by using recycled materials. The discarded concrete, block, stone, and sand, occupying over 90 % of the total recycled waste in weight could achieve a 93.5 % of carbon reduction potentially. It provides the opportunity to reveal the engineering details and carbon emission for a world-class super complex cross-sea transportation infrastructure. This study makes one of the first attempts to quantify life-cycle carbon emissions of cross-sea transportation infrastructure, which enriches foundational dataset for environmental impact assessment in this emerging field. The findings of this study can provide scientific references for formulating targeted low-carbon strategies for cross-sea transportation infrastructure across its different life-cycle stages.

A study of irrigation conflict in Khageri irrigation project

While Nepal is rich in water resources, there are also plenty of water related problems. Issues like water scarcity; improper water allocation, distribution, collection of water fees, farmers’ cooperation, performance of water users association etc give rise to water-induced conflict. As there is a wide range of such issues, this article examines only the conflict of water in the sector of irrigation and its management practices. This article assesses the major dimensions of irrigation management and how these dimensions give rise to conflict using a case study of the Khageri irrigation project (KIP). This study is based on the qualitative design including key informant interviews (KII), focus group discussion (FGD) and participant observation. The informants cover key stakeholders like members of water users associations, elderly farmers, local government officials, etc. Some of the major issues concern to conflict is the denial of riparian rights, repair and maintenance activities related to the canal, resource rights dilemmas, human encroachment to the canal, park control and legal restrictions etc. In addition, impact of climate change is one of the major factors that escalate conflict in the study area. Theory of co-management, Hardin’s tragedy of commons -position, interest, and needs (PIN), the best alternative to a negotiated agreement (BATNA), etc. were used as a theoretical lenses to analyze the findings. Analysis through these theories has further given rise to some other new theoretical models like neo-liberal socioeconomic resource management.

International Project Management – Another Challenge for Librarians. How Well Prepared Are We for This? A Case Study of the TRAIN4EU Project

The European Universities Initiative (EUI) was established in 2017. Its aim is to strengthen strategic partnerships between higher education institutions across the EU by building networks of universities. At the end of 2023, there were already 50 European University Alliances gathering 430 higher education (HE) institutions. In each of these Alliances, academic libraries are members, too. These libraries are already involved in intra-alliance projects, and these alliances will probably happen more often due to the EU’s project-driven approach. This practice paper is, to the authors’ knowledge, the first attempt to describe another challenge that European academic libraries currently face i.e., project management practice. The alliance partner universities operate under distinct national laws and institutional practices, making it challenging to easily align them for effective cross-university collaborations. Familiarity with the theoretical principles of EU project management and project management methodology greatly facilitates the preparation of the proposal and the work of the project. It also allows more effective management of the project as a whole or its individual parts. This paper maps the challenges that work in international projects brings and provides suggestions on how EUI libraries can utilize project management techniques, while also aiming at showing the paths to facilitate cooperation. Drawing from an analysis of the literature on project management that might apply in library-led projects to strengthen communities of purpose, the paper is based on the example of the work experience on the project TRAIN4EU, that was co-led by the academic librarians from the University of Warsaw Library, Poland, and run by 4EU + universities. The paper concludes with a set of recommendations based on TRAIN4EU practices, lessons learned, as well as pitfalls to avoid.

دراسة مقارنة لفعالية منهجية IMaRD وIMGSIE في مجال تكنولوجيا المعلومات

The usefulness of two well-known approaches, IMARD and IMGSIE, is compared in this paper within the context of information technology (IT) domains. Techniques are essential for organizing project workflows, improving productivity, and producing the intended results. IMARD, which comprises phases like Introduction, Method, Analysis, Results, and Discussion, is widely used in scientific academic papers and professional research to guarantee methodical problem-solving. On the other hand, IMGSIE methodology which consists of phases Introduction, Method, Generalization, Specification, Implementation, and Evaluation—has become more popular in technical and IT engineering projects. The objective of this paper is to evaluate the relative merits and demerits of different approaches in IT-related projects, taking into account variables like project and papers success rates, difficulties in implementation, and overall project management effectiveness. Discussion of case studies of IT projects that use both approaches offers practical insights into their efficacy. Key findings indicate that IMGSIE is more appropriate for graduation it projects needing iterative refinement and flexibility, even though IMARD offers a systematic and complete approach. Questionnaire was distributed to supervisors who used the IMARD and PPDIOO methodologies to evaluate its quality and effectiveness. The most important differences between the methodologies have also been identified, as well as where and when each method is used. Key words: IMGSIE methodology, IMaRD methodology, IMGSIE Lifecycle, Research methodology.

"Exploring the Process and Perceptions of Noise Conflicts Related to a Geothermal Project. A Case Study of Szeged, Hungary "

The use of renewable energy, including geothermal energy, is essential. Hungary stands out for its remarkable geothermal potential. However, these investments often lead to noise pollution, causing social conflicts between the local population and developers. This research presents a case study of a geothermal district heating renovation project in Szeged, Hungary. The study explores public perceptions and social conflicts related to the geothermal heating renovation, focusing on noise impacts. Local media articles reflect public perspectives, while opinions of key stakeholders (politicians, service providers) offer a broader view of geothermal drilling and its noise impacts. The study examines Szeged residents’ knowledge about the ongoing drilling, its benefits, and the conflicts it entails, particularly noise pollution. The empirical survey employs both quantitative and qualitative methods, including a questionnaire survey and online media analysis. Results show that the public lacks sufficient information about geothermal drilling and its noise impact, whilst online media coverage is unclear. Residents often confuse it with other developments, which neither media experts nor the project owner adequately clarify. Survey respondents provided a complex interpretation of noise impacts, mostly accepting the project but questioning why it was in their immediate neighbourhood and why drilling occurred at night. Inconsistent information emerged as a main problem, revealed through content analysis and compared with questionnaire results, highlighting a general issue of unawareness. Media analysis showed opportunities for public comment and consultation, but communication was often unsuccessful due to local residents’ lack of interest. Project organizers attempted to provide information through various platforms, but local media often lacked clear information, causing confusion between past and current geothermal projects and a lack of understanding of the development’s reasons and site selection criteria. Overall, there was a willingness to understand the problems associated with drilling, but this was only partially achieved due to inadequate communication.

DIGITALLY DRIVEN MODEL OF A CLIMATE-NEUTRAL ECONOMY IN TERMS OF GLOBAL FINANCIAL CAPACITY

The article explores the conditions and drivers for the development of a climate-neutral economy model, emphasizing the pivotal role of digital transformation. A crucial lever in deploying this model is the proactive engagement of international financial entities within the realm of global green financing. The study highlights the instrumental role of green funds as key players in shaping global financial capacity and providing multilateral support for climate change adaptation worldwide. It delves into the overarching frameworks and mechanisms of such assistance. Employing a systematic analysis alongside case studies of the Green Climate Fund's projects, the authors aim to identify the most impactful sectors for cultivating a climate-neutral economy. The research identifies four essential segments for achieving climate neutrality: digitalization for climate, strengthening the financial capacity and business sustainability, rethinking ecosystem development, and community empowerment. The investigation draws on extensive data regarding the execution of 240 climate projects across major beneficiaries of climate finance in Eastern Europe, Africa, the Asia-Pacific, and Latin America. It shows that modern climate finance demonstrates signs of geopolitical dependency and polarization in global influence. The findings argue for bolstering the regional presence of climate funds to increase the financial capacity to implement climate-neutral projects at the local level. The article underscores the scale of financial support required across each segment, as well as the leading role of pre-project preparation. The authors substantiate the overarching and twofold role of digitalization in the model of a climate-neutral economy. The digital transformation produces a whole cluster of independent and versatile IT products for green businesses, industries and governance. On the other hand, digitalization creates an informational environment and a powerful digital infrastructure for better efficacy of other crucial segments. Specifically, it provides digital decisions for financial solvency and sustainability of green businesses in terms of green lending, grants and Fintech; strengthens information awareness and involvement of vulnerable communities in green economy processes; promotes digital support for overall ecosystem adaptation.

Effects of joint tolerances on thermal bridging in precast concrete shear walls: Field tests and numerical simulations

Prefabricated buildings are gaining momentum due to their ecological benefits, speedy construction, and precision. However, unlike conventional cast-in-place structures, precast concrete shear walls are more susceptible to thermal and quality defects due to inherent tolerances. Four precast concrete shear wall connections prone to thermal bridges were identified through case studies of factories and real projects. Steady-state and dynamic modeling was conducted using determinant and stochastic matrices to assess the impact of joint tolerances on thermal distribution. The effects of joint tolerance magnitude and insulation material properties on linear thermal transmittance were investigated, complemented by a polynomial-based sensitivity analysis. A versatile prediction model was developed, integrating physical modeling and data-driven approaches to quickly quantify the thermal bridges of precast concrete shear wall connections. The results revealed a significant positive correlation between thermal bridges and joint tolerances, leading to extensive low-temperature regions within precast concrete shear walls. In dynamic modeling, joint tolerances contributed to additional heat dissipation, with a peak heat flux of 20.07 W/m. The sensitivity analysis demonstrated that joint tolerances greatly influence the correlation between linear thermal transmittance and insulation layer properties. Leveraging Categorical Boosting and Extreme Gradient Boosting, the prediction of linear thermal transmittance for precast concrete shear wall connections exhibited exceptional accuracy while significantly reducing computational costs. This research aids designers and policymakers by providing rapid and precise linear thermal transmittance calculations, offering valuable guidance for manufacturing prefabricated components to ensure enhanced energy efficiency and sustainability.

A Bayesian approach to estimate the capacity factor of offshore wind farms on the Brazilian coast

This work presents a Bayesian approach for inferring the capacity factor of an offshore wind farm. The calculation of the capacity factor depends on the power curve model and the probabilistic wind speed model, which in this work follows a Weibull distribution, whose scale and shape parameters are estimated using a Bayesian approach where the priors are independent gamma distributions, the likelihood is the Weibull distribution, and the posteriors are obtained by Hamiltonian Monte Carlo. The application of the described methodology is illustrated through a case study of an offshore wind power project located on the Northern coast of the Rio de Janeiro State, Brazil.
