Urban Renewable Energy Communities and Energy Poverty. A proactive approach to energy transition with Sun4All project

The transition to an environmentally sustainable, low-carbon economy requires fundamental transformations in various sectors such as industry, technology, and especially in society as a whole. Adopting and encouraging community energy are the key policies to facilitate sustainable energy and ecological and social transition. The Sun4All methodology aims at the design, promotion and building of energy communities based on solidarity, to contrast energy poverty and foresee the engagement of vulnerable households that normally have many difficulties in becoming active members of an energy sharing project realising PV plants. The selection of the beneficiaries’ families in the urban context is a process both technical, including socio-territorial GIS-based analysis, and social, activating the participation of grass-root associations, local schools, and facilitators. The strategic role of the municipality is coherent with the SECAP and results in the offers of several public building roofs with PV plants that are the cores of the Sun4all Energy Communities and will ensure the delivery of economic benefits for the vulnerable households, while through workshops, site visits to the plants, and communication activities will increase the citizens' knowledge. The purpose of this paper is to explore the benefits that go far beyond energy efficiency, which is only the starting point

Innovative Uses of Rain Screen Cladding. CFD and Gas Dispersion Analysis of a Prototype

Abstract In this work, both CFD and CH 4 dispersion analysis in rain screen cladding were carried out, in order to reduce the visual impact of Natural Gas distribution network in civil buildings ensuring high safety standards. In the first part of the work it was conducted the parametric analysis in order to identify the main physical parameters that influence the air velocity in air-gap. Subsequently, CFD simulations were carried out in order to evaluate how the geometric and constructive characteristics can influence the air velocity inside the cavity. In particular, were realized both 2D and 3D models, and was used Ansys Fluent 6.3 software. Finally, Natural Gas dispersion analysis was carried out, in order to evaluate the safety against explosive atmosphere

Adsorption gas Heat Pump fuelled with hydrogen enriched natural gas blends: The analytical simulation model development and validation

This study deals with the implementation of an analytical model to simulate the energy performance associated to a commercial Gas adsorption Heat Pump, when H2NG (Hydrogen Enriched Natural Gas) blends are used as fuel. In detail, a water source heat pump manufactured by Robur (GAHP-WS) has been used as a reference device for building the simulation model within the MATLAB-Simulink environment. Thereafter, the simulation results have been validated by the experimental campaign, testing on field and in actual operating conditions the heat pump. Specifically, the model has been developed by implementing the WaterAmmonia mass and energy balances for each component. It is able to evaluate fuel consumption, efficiency in terms of GUE, required thermal power from the cold heat sink as well as the water outlet temperature at the evaporator, once the heating load is used as the main input. The experimental campaign for the model calibration and validation has been carried out over the winter season. Additionally, the heat pump performance has been detected when it operates to supply hot water at 60 °C and 55 °C, and it is fuelled with growing hydrogen fractions, starting from 0% vol., 5% vol. up to 10% vol. In the end, the standard errors as well as the relative ones affecting the main output parameters have computed for the validation process. From the outcomes it emerges that the average relative standard error related to all load conditions is lower than 2.5% for natural gas operation. On the contrary, it ranges between 2.5% and 4% when H2NG at 5% and 10% by volume have been burnt

Experimental envelopes and their integration in the building information modeling energy simulation process

The present contribution deals with an ongoing Italian research which includes several steps and it is approaching to its final stage. The main goal is analysing and testing the feasibility of municipal waste reuse for designing building envelopes for Near Zero Energy Buildings (NZEB), so as to contribute to the decreasing demand for energy and improve eco-friendly waste management in urban areas. First, prefab building components have been designed using selected waste and their thermal and acoustic behaviours have been calculated, according to the European rules; then the economic costs of the obtained building envelopes have been assessed and compared to common building structures to verify their possible appeal on the Italian market, and finally the components have been assembled in the project for a small NZEB building: a didactic classroom for the Mira Porte Primary School (Venice, Italy). This paper refers to the in-depth elaboration of the project, mainly concerning fire and pollutant protection, and it focuses on the reliability check of the Building Information Modeling (BIM) parametric model, especially as concerns non-conventional materials and components. The relative building energy behaviour has been obtained exporting the BIM energy simulation model using the EC770 Integrated Design for Revit plug-in. Finally, a comparison between the results obtained with the traditional energy assessment (according to D.M. 26/06/2015) and those using the BIM model has been made to evaluate the interoperability between architectural modeling software and the energy simulation one

SUMmer school on European iSland LANDscape (SUMESLAND)

OBJECTIVES: The main goal of this project is to develop a multinational outstanding summer school on European island landscape and cultural heritage, and to disseminate to students the methodology carried out by the ESLAND Project funded by the EC Culture Programme. The course will facilitate cooperation and mobility between European universities who are dealing with this emerging research field, improving both know-how and exchange of educational practices and programmes. This pioneer course therefore will tackle landscape theory, e-tools and information system technologies, as well as debating issues concerned with teaching content and new curricula approaches. It will in this way support the implementation of the European Landscape Convention, which requests member states to design educational programmes and courses on landscape. TARGET GROUPS are students in landscape studies and related subjects. PhD students are the main target, but exceptional Master students in their final year could also be considered. MAIN ACTIVITIES: A) Intense cooperation between lecturers of the institutions involved will precede the summer school, leading to setting up a detailed programme. B) Particular attention will be given to organisation and logistics. C) The ten-day course will be composed of lectures, discussions, workshops, teamwork and field trips. D) The interdisciplinary theoretical approach will be enriched by indoor and outdoor interactive activities with the students. E) The lecturers in charge will debate innovative teaching and curricula approaches emerging from SUMESLAND, and will prepare a report that will be useful for other tutors in the subject. LEARNING OUTCOMES: Exchange of know-how and teaching approaches. Innovative teaching & learning landscape methods. Interchange of teaching best practices in landscape. Improved academic performance. E-tools and GIS mapping skills. Enhancing possibilities for students and lecturers to meet and cooperate in new studies on European island landscapes that would not be possible otherwise, covering: island landscape history, characterization, identity and scenario. EXPECTED OUTPUTS: SUMESLAND Summer School website. Course programme with teaching & learning activities. Course and field trip material. Island landscape history methodology. Island landscape identity interactive workshop. Island landscape character mapping. Island landscape scenarios visualisation. INNOVATION Students and lecturers will be encouraged to consider European island landscapes from the point of view of cultural heritage, by looking at the unique identity and values these landscapes have for the people of Europe (landscape identity), by describing island landscape evolution (landscape history), assessing present landscape conditions (landscape characterisation) and visualising future scenarios (landscape scenario). The knowledge and link of these topics are essential for a sustainable future of European island landscapes. However innovative approaches like this proposed by SUMESLAND are lacking in the current treaching and learning of European universities, but urgently needed to achieve sound conservation and development of island landscapes. As mentioned before, this has been urgently requested also by European Conventions and Directives in the subject. LERNING OUTCOMES & SUBJECT RELATED COMPETENCES • Innovative landscape teaching & learning methodology on island landscape history, characterisation, identity, scenario and their interlinks • Know-how and exchange of teaching best practices and learnign skills and on the above • Increased academic performance and developed curricula in island landscape studies • Possibilities for students and lecturers to meet, exchange and cooperate in innovative studies on European island landscapes that would not be possible otherwise. • Facilitated future employment of graduates in tha above sectors tackle
