Construction of a webgis tool based on a gis semiautomated processing for the localization of p2g plants in sicily (Italy)
2021
The recent diffusion of RES (Renewable Energy Sources), considering the electric energy produced by photovoltaic and wind plants, brought to light the problem of the unpredictable nature of wind and solar energy. P2G (Power to Gas) implementation seems to be the right solution, transforming curtailed energy in hydrogen. The choice of the settlement of P2G plants is linked to many factors like the distances between the gas grid and the settlement of RES plants, the transportation networks, the energy production, and population distribution. In light of this, the implementation of a Multi-Criteria Analysis (MCA) into a Geographic Information System (GIS) processing represents a good strategy …
GIS-data related route optimization, hierarchical clustering, location optimization, and kernel density methods are useful for promoting distributed …
2019
Currently, geographic information system (GIS) models are popular for studying location-allocation-related questions concerning bioenergy plants. The aim of this study was to develop a model to investigate optimal locations for two different types of bioenergy plants, for farm and centralized biogas plants, and for wood terminals in rural areas based on minimizing transportation distances. The optimal locations of biogas plants were determined using location optimization tools in R software, and the optimal locations of wood terminals were determined using kernel density tools in ArcGIS. The present case study showed that the utilized GIS tools are useful for bioenergy-related decision-maki…
Informational analysis of forest landscape spatial heterogeneity
1999
Summary Under the perspective of forest ecosystem management, landscape is interpreted as a functioning structure. From an inventory and monitoring operational point of view, such an approach implies wise use of geographic information systems and remote sensing techniques enabling a global view of the territorial mosaic. From a methodological point of view, landscape ecology theory may be used as the assessment framework. Remotely sensed data provide excellent opportunities for the involved analyses, using both vegetation density measures and spatial statistics. The objective of this paper was to assess landscape spatial heterogeneity using an analysis method based on Shannon's information …
Wind speed spatial estimation for energy planning in Sicily: A neural kriging application
2008
Abstract One of the first steps for the exploitation of any energy source is necessarily represented by its estimation and mapping at the aim of identifying the most suitable areas in terms of energy potential. In the field of renewable energies this is often a very difficult task, because the energy source is in this case characterized by relevant variations over space and time. This implies that any temporal, but also spatial, estimation model has to be able to incorporate this spatial and temporal variability. The paper deals with the spatial estimation of the wind fields in Sicily (Italy) by following a data-driven approach. Starting from the results of a preliminary study, a novel tech…
Visualization of the Renewable Energy Resources
2016
The methods of the renewable energy resources visualization are analysed in this work, the examples of the systems and possible architecture of the renewable energy monitoring systems of the Republic of Kazakhstan are considered. Successful practices are analysed, the leading scientific organization in the field of green energy are considered, a comparative analysis of geographic information systems and data sources in the field of green energy is performed. Possible software architecture of the system based on 3M paradigm of geographic information system (multilayer views, multilayer architecture and multi-agent interaction) is considered.
Improving energy efficiency of commercial buildings by Combined Heat Cooling and Power plants
2020
Abstract Commercial buildings play a key-role in the energy consumption of the building sectors. Recent statistics have shown that as the number of commercial buildings is continuously increasing, their effects on energy consumption are expected to grow. These buildings are characterized by high energy demand mainly due to lighting and HVAC requirements. Rooms of energy saving exist by considering that: (i) electricity demands and HVAC requirements occur simultaneously during the day and (ii) both demands are currently satisfied by using separate energy systems. It is apparent that the adoption of polygeneration systems could represent a valid solution to achieve energy savings. To this aim…
Conceptualizing Core Aspects on Circular Economy in Cities
2021
Currently, there are many different interpretations in the literature of what a circular economy is and how it functions. As cities are still facing challenges to become fully sustainable, the need for a comprehensive analysis of how the circular economy can be implemented in urban areas is increasing. This article aims at outlining circular cities by their key characteristics and to further explore and provide a framework for fostering circularity at the city level. In order to achieve this goal, we performed a systematic review and analyzed key papers published in the field of circular economy to determine how circular economy practices form circular cities. We discovered that cities play…
Sustainable Infrastructure Projects: Systemic versus Traditional Delivery Models
2021
Sustainability involves multiple environmental, technical, social and economic factors, and such complex analysis requires systemic solutions. Delivery models are key to achieving system benefits and enhancing sustainable development in infrastructure investments. They define the phases of a project, incentive structures, risk sharing and the relationships among the actors in it. They are usually developed early in the project and determine the project dynamics and outcomes. We compared traditional delivery models with systemic ones. We identified and illustrated elements that differ between them through two cases. The contribution is an increased understanding of how systemic infrastructur…

High rates of short-term dynamics of forest ecosystem services
2021
Currently, the main tools for assessing and managing ecosystem services at large scales are maps providing snapshots of their potential supply. However, many ecosystems change over short timescales; thus, such maps soon become inaccurate. Here we show high rates of short-term dynamics of three key forest ecosystem services: wood production, bilberry production and topsoil carbon storage. Almost 85% of the coldspots and 65% of the hotspots for these services had changed into a different state over a ten-year period. Wood production showed higher rates of short-term dynamics than bilberry production and carbon storage. The high rates of dynamics mean that static snapshot ecosystem service map…
