WebGIS Open-source Platform for Localizations of New P2G Plants in Sicily
(Wydawnictwa AGH, 2024) La Guardia, Marcello; D’Ippolito, Filippo
The climatic emergency that involves the globe has led targets of greenhouse gas reduction in the EU and all over the world. In this scenario, recent advances in renewable renewable energy sources (RESs) have focused interest on the diffusion of power supplies that are produced by photovoltaic and wind plants. The non-programmable nature of these energy sources has led recent studies to consider the power-to-gas (P2G) solution as an opportunity for employing the curtailed electric energy by converting it into hydrogen. The localizations of P2G plants depend on several factors regarding power production, distances, and population distributions. The necessity of integrating these factors led this work to study the development of a cost function that is hosted by a web-based GIS (geographic information system) platform, thus allowing for the storage, elaboration, and web fruition of an entire data set that is related to the possible new localizations of P2G plants. The structure is based on open-source technology and creates a solution that is easily employable by specialists. The developed platform is composed of different remotely connected blocks that are solely based on open-source technology and is focused the interest on the territory of Sicily (Italy). GIS software, a RDBMS database, a geospatial server (Geoserver), a Python optimization module, and a WebGIS visualizer are integrated. This work represents a scientific contribution to the management of energy sources, with a particular focus on policies that are based on hydrogen technology. In fact, different data sets that contain several levels of information that are related to the management and the localization of P2G plants will be even further employed in the future.
Optimizing Selection of Sustainable Material-extraction Sites with GIS-based Decision-support Systems (AHP/MACBETH): In-depth Case Study from Settat, Morocco
(Wydawnictwa AGH, 2024) Amellal, Issam; Amellal, Asmae; Hattabi, Said
In today’s world, sustainability is crucial, particularly in managing natural resources for sustainable development. Often, environmental impacts of new activities are overlooked, worsening the effects on already vulnerable environments. Our study uses two multi-criteria decision-making tools, MACBETH and AHP, integrated with GIS technology, to evaluate quarry sites in Settat Province, Morocco. This methodology classifies sites by suitability, based on criteria aligned with sustainable development goals. We found a high consistency between MACBETH and AHP, with less than 4% divergence in criteria weighting, confirming the robustness of our integrated approach in making location-based decisions for quarries. The resulting maps clearly delineate zones from unsuitable to highly suitable for quarrying. Beyond assessing current quarrying practices, our findings offer strategic insights for future site planning and establishment, showcasing adaptability and potential for replication. This research provides a practical model for improving material extraction practices, aligning with sustainable development needs, and serving as a valuable tool for policymakers and industry stakeholders.
Instruments for Supporting Implementation of Sustainable Development Goals for Construction Sector – Case of Poland
(Wydawnictwa AGH, 2024) Szopińska, Kinga; Ramczyk, Marek
Currently, three billion people face dangerous levels of air pollution and rely on non-renewable energy sources for cooking and heating. Due to its environmental impact, the construction sector is a particularly important area for implementing sustainable development policies. On July 10, 2023, the UN published The Sustainable Development Goals Report 2023 (SDGs). In accordance with the provisions of Goal 7 (which was discussed in the above document), the international community should increase its share of renewable energy sources in the global energy mix and promote investment in clean energy technologies by 2030. Achieving this goal necessitates the introduction of support mechanisms to enhance the energy efficiency of residential buildings. Hence, this study aims to showcase the legal and financial tools that aid the growth of energy-efficient construction in Poland, to compare the renovation costs of an existing residential building in order to meet energy-efficiency standards, and to detail the financial support that is available for planned thermal-modernization efforts.
Advanced Method for Determining Land Plot’s Physical Surface
(Wydawnictwa AGH, 2024) Malashevskyi, Mykola; Malashevska, Olena
"This study examines the issue of the accuracy of physical surface calculations for land plots with complex configurations and reliefs. The goal of the study was to develop a methodology for determining the surface area of land plots with complex configurations and reliefs. The presented model was based on the finite element method. The developed method allows one to evaluate a relief’s complexity by using a dimensionless mean physical surface complexity factor"," a Fortran program was developed for the methodology. Experiments that proved the effectiveness of the methodology and a comparative analysis of those areas that were calculated by the presented method and TIN model were carried out. The research findings proved the practicability of the methodology for calculating the physical surfaces of land plots with complex configurations. The presented methodology can be used for flood modeling, landscape and vertical planning, etc."
Weight Impact on Comparative Evaluation of Topographic Data
(Wydawnictwa AGH, 2024) Borkowska, Sylwia; Bielecka, Elżbieta; Pokonieczny, Krzysztof
The paper addresses the problem of weighting in an analysis that supports the selection of a categorical data set according to user needs. Using the Relative Change (RC) of the Compound Correspondence Index (CCI), it is shown that weights have a significant impact on user choice – reaching extreme values in both urbanized and forested areas. Decreasing the weights from 0.25 to 0.17 in forested and built-up areas resulted in the maximum variations that were seen in the hot spot maps, with cold areas generally corresponding to built-up regions and hot areas to forested areas. The analysis covers seven counties that are located in different regions of Poland: Pomerania, Podlasie, Mazovia, Greater Poland and the Beskidy Mountains.
