Sea wave energy to supply the Aeolian Islands in sustainable way

2018

The diffusion of technologies supplied by Renewable Energy Sources is contributing in the challenge of reduction of energy dependence from fossil fuels, avoiding the emission of several polluting substances and greenhouse gases. Despite the technological development and important results around the world, in several remote areas or small islands the electrical energy production is based on obsolete technologies, supplied by fossil fuels. This solution is not sustainable for the environment, as the emissions of several pollutants. Focusing the attention on small islands, these areas usually have a standalone grid, as the high cost to build an electrical connection to the mainland, in compari…

A Hybrid AHP Approach and GIS-Based Methods as Fundamental Tools in the SECAP’s Decision-Making Process

2023

Adapting to climate change and mitigating its impacts are the main challenges for cities today. One objective that the European Commission has set in recent decades is reducing climate change inaction, and several political actions have been implemented. Among these actions, the Covenant of Mayors led to the development and adoption of Sustainable Energy and Climate Action Plans (SECAPs) by many cities worldwide. A challenge that local authorities must face during the development of a SECAP is the identification of the policies to be included in the plan. This paper presents a case study to show the validity of using a hybrid analytic hierarchy process (AHP) approach and various geographic …

Societal implications of sustainable energy action plans: from energy modelling to stakeholder learning

2019

This article investigates the potential impact of sustainable energy action plans (SEAPs) on local development through a two-step methodology involving participatory planning and quantitative analysis. The first phase relies on a participatory system mapping (PSM) approach and generates a causal structure at the basis of the urban model. In the second phase, we transform the qualitative map into a system dynamic model which evaluates the effect of the SEAP on social, economic and environmental indicators. This methodology was applied to the case of Cascina Municipality (Italy). Through scenario analysis, we show that some indirect feedback can harm the achievement of the 20% emission reduct…

Supporting the Sustainable Energy Transition in the Canary Islands: Simulation and Optimization of Multiple Energy System Layouts and Economic Scenar…

2021

The Canary Islands have great potential for the implementation of sustainable energy systems due to its availability of natural resources. The archipelago is not connected to the mainland electricity grid and the current generation system is mainly based on traditional fossil fuel. Therefore, the islands strongly dependent on fuel importations, with high costs due to logistics. Furthermore, due to the inadequate coverage of residential heating and cooling needs, the per capita energy consumption is far below the Spanish national average. This occurrence has inspired an intense debate on the current development model of the Canary Archipelago, which has led to the implementation of actions a…

Palermo, ZEN District. An occasion of urban re-qualifying

2012

Among the changes made to the original scheme proposed by Amoroso Group, were some that showed the willingness to accommodate the constraints established by the local council and were designed primarily to protect certain pre-existing historical sites in the area. Consequently, the gridded, dense neighbourhood Zen 2 had to be opened in certain parts. Thereupon on the South-East quarter the "0D" insula, the citrus grove, the historical outskirts and the school in Trapani Pescia Street detect an emblematic fragment, useful to understand the contradictions that exist in this district, where heterogeneous elements form self and distinct parts. The design of new residences in this area is an occ…

Improvement of energy efficiency and quality of street lighting in South Italy as an action of Sustainable Energy Action Plans. The case study of Com…

2014

Existing street lighting systems in most of Sicilian cities are often inappropriate due to the obsolescence of light sources and luminaires and of unsuitable light control systems unable to provide efficient on-off and dimming strategies. Improvement of energy efficiency in street lighting systems can be one of the key actions adopted by Public Administration in developing Sustainable Energy Action Plan in the framework of the “Covenant of Majors” activities. As a task of FACTOR 20 project a set of planning options have been analysed and proposed for Sicilian cities. Particularly, street lighting efficiency projects have been studied for representative case studies. A detailed survey of the…

Implementing the sustainable energy (and climate) action plans: quasi-steady state or dynamic building modeling approach?

2020

Actions contemplated in Sustainable Energy (and Climate) Action Plans (SEAPs), which municipalities adhering to the EU initiative called “The Covenant of Mayors” are required to prepare, regard many sectors, among which are buildings. To implement such plans, it is necessary to make use of methods for predicting energy use in buildings. Technicians involved in this tend to adopt easy-touse simulation models because of the common mid-level expertise of the offices involved. However, such simplified methods could result in a less accurate evaluation of the energy demand of buildings. In this paper the suitability of the quasi-steady state and the dynamic approach, in the frame of these new ur…

Integrazione di celle fotovoltaiche ibride nel vetromattone

2012

L’invenzione riguarda l’integrazione del vetromattone con celle solari ibride (organiche/inorganiche), conosciute come Dye-sensitized Solar Cell (DSC). La combinazione del vetromattone con le DSC consente di migliorare le prestazioni del prodotto originario rendendolo in grado di produrre energia pulita. Le caratteristiche di trasparenza e isolamento termo-acustico del prodotto possono essere regolate agendo sulla configurazione delle DSC. Il prodotto può essere assemblato a formare pannelli fotovoltaici per la realizzazione di facciate traslucide energeticamente “attive” in varie condizioni luminose (condizioni di luce diffusa o artificiale) e indipendentemente dall’angolo di radiazione so…

The integration of Dye-sensitized Solar Cell (DSC) with the glassblock is disclosed. The combination of the two technological elements the glassblock and the DSC module enhance their own peculiarities. The final complete product is ready-made for installation owns the qualities of the glassblock and produces sustainable energy at the same time. The transparency and the thermo-acoustic insulation may be modulated according to the specific requirements of each case of installation. The product may be used for example to create PV panels for glazed and translucent façades that are able to perform efficiently in all light conditions (even in diffuse light also converting internal artificial light) that are not dependant on the angle of the solar radiation and do not suffer from the high operative temperatures of functioning due to the peculiarities of the DSCs. DSCs are made of economic and biocompatible materials and are produced with low-cost and highly productive printing methods on rigid or flexible substrates. With the integration of DSC modules with the glassblock PV panels coincide with the envelope itself so that they do not need any further structures to be installed on and allow the possibility of subtract from the price of the panel the price of the substituted building element allowing further economies. DSCs can be printed in different colours and with various patterns offering to designers and customers the possibility of intervening on the glassblock aesthetical aspect also taking advantage of the peculiar modularity of the glassblock for larger compositions of drawings on the building’s façade. Seven Hypotheses of integration are discussed in order to obtain DSC-integrated glassblock ready for the construction of a precast and dry-assembled PV panel which can use the horizontal and vertical cavities between the glassblocks to house plastic profiles where the electric interconnections and the steel bars -useful for improve the mechanical resistance of the panel- are integrated.Settore ICAR/10 - Architettura Tecnica
