Urban Retrofit and Resilience: The challenge of Energy Efficiency and Vulnerability

Urban retrofit is becoming increasingly established as one of the most effective solutions to contain the energy consumption of the existing building stock, to reduce vulnerability to natural and man-made risk and generally improve the quality of built space. However, the planning of retrofit interventions at urban scale should take account of the actual feasibility of measures lest they remain only on paper. This contribution supplies an overview of the many issues related to the subject of urban regeneration, proposing a procedure to identify practical interventions to minimize costs and maximize benefits, in terms of energy efficiency, an increase in resilience and improvement in the quality of the building stock. This procedure was applied to a case study of a neighborhood in the city of Naples, a high-density urban area which is particularly vulnerable to volcanic and seismic risk, and to risks due to climate change.

Green Infrastructure and climate change adaptation

One of the main challenges urban areas, and more particularly the compact ones, are facing is their adaptation to climate change. In recent years, is had been recognized that a more ecosystem approach to spatial planning can play a critical role in meeting these challenges. Green Infrastructure (GI) and its integration in spatial planning emerges as one of the most appropriate and effective ways to improve microclimate and tackle the impacts of climate change and mainly the Urban Heat Island (UHI) effect. This paper initially attempts to clarify the term GI and portrays its benefits and its role as an important spatial planning tool to fulfill different environmental, social and economic needs of urban areas. Then, the paper proceeds to an empirical evaluation of the role of GI in reducing the vulnerability to UHI effect in a compact urban area of the city of Thessaloniki. For this reason, a simple methodology is developed with a twofold purpose: to recognize the risks posed by climate change and especially UHI and to assess the potential offered by available in a compact area GI assets as well as by their redesign in order to maximize their contribution to climate change adaptation.

Telesia Archaeological Project: Indagini nella basilica e nel foro (2014-2015)

The Telesia Archaeological Project is an initiative that will make a significant contribution to thi historical and archaeological knowledge of the urban area of the Roman city of Telesia, located near Benevento (S. Salvatore Telesino). The first and second season of the Telesia Archaeological Project (2014-2015), conducted under the supervision of the Archaeological Superintendence, and thanks to the indispensable collaboration of a private landowner, provided results of great scientific interest. There was the possibility to investigate part of a significant building of imperial age, richly decorated, identified with the basilica of the city. It was possible to establish, in addition, that this large building (36 by 21 m ca) was opened, through a great brick colonnade, to the forum, localized in summer 2015 with certainty for the first time. The extraordinary large double colonnade (porticus duplex), 9 meters wide, covering the entire façade of that public building, was erased in the fifth century AD, probably after two earthquakes that seriously damaged the city in 346 and 375 AD.
