The urban design guidance for the unmanaged spaces under elevated expressways upon users’ preferences
2016
There are many bridges in the Iranian major cities. It is still proceeded for constructing new bridges in order to solve traffic problems. The spaces under bridges and the expectations of users are rarely important for city officials and designers. Hence, this research is looking for guidelines of designing the unmanaged spaces under city bridges considering the environmental preferences of users. The main goal of this research is to achieve urban design guideline for designing the unmanaged spaces under elevated expressways based on expectations of individuals. This research is based on theoretical studies in the field of urban design, under bridge spaces, unmanaged spaces as well as envir…
Alteration-Induced Volcano Instability at La Soufrière de Guadeloupe (Eastern Caribbean)
2021
International audience; Volcanoes are unstable structures that deform laterally and frequently experience mass wasting events. Hydrothermal alteration is often invoked as a mechanism that contributes significantly to volcano instability. We present a study that combines laboratory experiments, geophysical data, and large-scale numerical modeling to better understand the influence of alteration on volcano stability, using La Soufrière de Guadeloupe (Eastern Caribbean) as a case study. Laboratory experiments on variably altered (advanced argillic alteration) blocks show that uniaxial compressive strength, Young's modulus, and cohesion decrease as a function of increasing alteration, but that …
PROGETTARE L’ADATTAMENTO. Resilienze di agricoltura urbana nel contesto europeo
2022
I crescenti fenomeni legati al cambiamento climatico spingono le città a sviluppare piani di resilienza che possano rispondere in termini di sostenibilità ambientale, sociale ed economica. Le strategie nature-based possono rappresentare una soluzione; tra queste l’agricoltura urbana può contribuire ad aumentare la resilienza dei tessuti urbani europei. Questa attività è stata più volte oggetto di interesse in periodi di crisi come impegno comunitario dai caratteri sociali, oltre che produttivi ed educativi. Attraverso un excursus storico e una successiva analisi di casi studio contemporanei, il paper fornisce strumenti progettuali per intervenire nel costruito con strategie che spaziano dal…
IEA EBC Annex83 Positive Energy Districts
2021
At a global level, the need for energy efficiency and an increased share of renewable energy sources is evident, as is the crucial role of cities due to the rapid urbanization rate. As a consequence of this, the research work related to Positive Energy Districts (PED) has accelerated in recent years. A common shared definition, as well as technological approaches or methodological issues related to PEDs are still unclear in this development and a global scientific discussion is needed. The International Energy Agency’s Energy in Buildings and Communities Programme (IEA EBC) Annex 83 is the main platform for this international scientific debate and research. This paper describes the challeng…
Assessing Urban Environmental Sustainability by Means of Indicators: The Case of the Heritage Buildings
2002
Man in developed countries is looking for new and more suitable paradigms of a correct evolution, founded on an improved level of quality of life, on a pollution-free environment and on the availability of rising amount of time to be spent in pleasure and cultural activities.
More nature in the city
2020
According to projects and practices that the Italian botanists and ecologists are carrying out for bringing “more nature in the city”, new insights for a factual integration between ecological perspectives and more consolidated aesthetic and agronomic approaches to the sustainable planning and management of urban green areas are provided.
Nonlinear black-box models for short-term forecasting of air temperature in the town of Palermo
2011
Weather data are crucial to correctly design buildings and their heating and cooling systems and to assess their energy performances. In the intensely urbanized towns the effect of climatic parameters is further emphasized by the Urban Heat Island (UHI) phenomenon, known as the increase in the air temperature of urban areas, compared to the one measured in the extra-urban areas. The analysis of the heat island needs detailed local climate data which can be collected only by a dedicated weather monitoring system. The Department of Energy and Environmental Researches of the University of Palermo (Italy) has built up a weather monitoring system that works 24 hours per day and makes data availa…
Una piazza per il Belìce. Strategie per il Territorio Arcipelago
2019
Le grandi città globali non sono più gli unici contesti per la competizione territoriale: l’Italia è un importante esempio di un nuovo sistema di piccole e medie città, una sorta di arcipelago di spazi tenuti insieme da identità locali, animato dalle comunità, ma frenati da geografie impervie. L’articolo definisce come un territorio può applicare protocolli e azioni innovativi per la sfida dell’Italia interna. Questa “Inner Italy” può essere una piattaforma per l’innovazione locale, lo sviluppo sostenibile, la resilienza ecologica e sociale e la coesione territoriale, come mostrato nella letteratura internazionale, in riferimento sia al Territorio-Arcipelago (Carta, 2016), sia ai contesti u…
Pop-Up Architecture as Urban Regeneration
2016
Recent ideas in urban planning, conceptualized e.g., as New Urbanism, emphasize the humane point of view of the city. The focus of these ideas is on the citizens and their experiences of feeling comfortable and at home in the urban space; people´s possibilities of spending leisure time in the city centre; and enabling the encounter of different people in the city space in order to bring the inner city to life. To revitalize the less used, unused, or decayed city spaces by using them as venues for diverse cultural activities is a part of these ideas. The means of urban regeneration often rely on ambitious and permanent transformations of the urban space, such as constructing cultural infrast…
