Computing methods for resilience: evaluating new building components in the frame of SECAPs
2019
Resilience represents a new important feature that the anthropic systems, and cities among them, are called to cope with. In fact, the increasing negative stresses to which urban contexts are exposed, and mainly the climatic pressures, call for the capability of adapting to these modifications and, possibly, to restore the ex-ante situations. The role of the buildings and their envelope components is of crucial importance to this aim. This paper analyses the features of resilience of the roofs of buildings by means of proper quantitative indexes. On purpose, the performances of green and cool roofs are compared. The possibility of adopting nonstructural solutions, like the windows shading d…
Special Issue “Smart Urban Lighting Systems”
2020
The design and operation of multifunctional infrastructures for public lighting as well as their impact on the urban environment and citizens’ life is today of great interest. The cost of energy for public lighting is often an issue for the budget of municipalities. Furthermore, researchers’ and designers’ attention is increasingly focused on aspects of public lighting not directly valuable through economic factors. Starting from the “quality” of the light environment, looking at citizens’ visual comfort, the light has to be considered as an instrument to improve the urban context and objects therein (including buildings). Indeed, urban degradation (lack of infrastructures, maintenance, ser…
INNER AREAS
2022
Inner areas, as defned in the Italy’s National Strategy (SNAI), are part of the territory that plays a central role in the cultural and social fabric of our communities, are an essential component of our society, economy, and environment. However, they are still often neglected and overlooked, resulting in deterioration, abandonment, and social exclusion.For this reason, it is crucial that the felds of architecture, restoratio and architectural history and urban and territorial planning are committed to revitalizing and enhancing inner areas. These disciplines have the knowledge, skills, and tools necessary to create sustainable and innovative solutions that can transform these territories …
Architectural technologies for life environment: improving sustainability by reusing wastes in novel geopolymeric mortars
2021
Recently, implementing construction to a more sustainable industry has become a focal point in the international debate due to the huge volume of non-renewvable raw materials and energy consumed every year, along with the significant emissions of green-house gases and global warming, often associated to the supplementing industries. Besides, valorisation and reuse of industrial wastes and by-products is a viable alternative to the traditional industrial system, becoming a compelling topic to improve processes and materials sustainability. This paper fo- cuses on the development of a novel class of green geopolymers, worldwide considered a solid and sustainable alternative to Portland cement…
Acciones para mejorar la eficiencia energética en los edificios en Europa: estado del arte sobre los standards técnicos
2022
The paper is aimed at reviewing the state of the art of the European technical normative implementation during the last decades concerning the building energy efficiency. Indeed, it is well acknowledged that the present building stock is largely obsolete and inefficient: in the European context alone, around 75% of the buildings is not energy efficient and most are expected to be in use until 2050. Consequently, buildings require not only a general rehabilitation, to extend, or even avoid, its end-of-life time, but also a complete afterthought of their energy performance. That is extremely urgent to improve the overall sustainability of the construction sector that, alone, is one of the mai…
An innovative approach to manage uncertainties and stock diversity in the EPBD cost-optimal methodology
2018
The EU Energy Performance of Buildings Directive (EPBD) 2010/31/EU is a step in the right direction to promote near zero energy buildings (NZEB) in a step-wise manner, starting with minimum energy performance and cost optimal thresholds for “reference buildings” (RBs) for each category. Nevertheless, a standard method for defining RBs does not exist, which led to a great divergence between MS in the level of detail used to define RBs for the EPBD cost-optimal analysis. Such lack of harmonisation between MS is further evident given the resulting large discrepancies in energy performance indicators even between countries having similar climate. Furthermore, discrepancies of 30% or higher betw…
Architettura emergenziale: buone pratiche esecutive
2022
This paper provides a comparative overview of different types of (temporary) shelters that have recently been used in various field locations in response to a forced displacement due to disastrous events. In particular, possible strategies useful to increase the sustainability of the humanitarian response and reduce the carbon footprint, while ensuring the adequacy and suitability of the shelters themselves, are here explored. This study investigates a systematic design framework that is often constrained by many obstacles such as the limited availability of low-cost materials, and a lack of local labour experience. To reduce the negative impact of a disaster, especially in the developing c…
Architectural technologies for life environment: passive cooling strategies in the architectures of the Mediterranean area.
2020
The Mediterranean area is a highly interesting place where various States, characterised by different people, histories, and cultures face. Reigns, religions, powers, state structures, people, nationalities, etc., everything seems to be extremely different and far. On the contrary, there are some cultural points that are much closer than they officially appear. Indeed, historically, the commercial trades between the various countries have always been highly intense and the Christian and Muslim reigns, even if in a continuous state of conflict, were reciprocally linked by deep (financial) interests. Therefore, that translated in a wide trade of goods that moved on the Mediterranean Sea acros…
THE SICILIAN DEFENSIVE SYSTEM: THE COASTAL TOWERS. THEORY AND TECHNIC MEET IN UNIQUE LANDMARKS
2016
Sicily has historically experienced a massive colonial occupation due to its strategic position among the Mediterranean Sea. Still today, its tactical importance is under everybody’s eyes with at least 15 NATO’s headquarters. Thus, it’s easily understandable how defending such a large territory was particularly important which, in turn, meant guarding and protecting more than 1600 km of coasts, leading to a possible supremacy on the trading routes through the Mediterranean area. This work will analyse the Sicilian coastal towers, a real typology that exploited traditional construction technologies and local materials integrated by instances of military engineering, in a continuous relations…
Strategies for building energy retrofit in the mediterranean basin
2012
The paper focuses on passive and active strategies for achieving sustainable recovery of existing buildings in the Mediterranean Basin, in order to improve indoor comfort and reduce carbon dioxide emissions in the atmosphere. The Mediterranean Basin is characterized by relatively mild winters and very warm summers. Although Mediterranean climate conditions offer excellent opportunity for the application of alternative energy sources (eg. wind, solar, hydroelectric), they are not very applied yet. Italy and Sicily in particular, comparing to most of EU countries , hang still behind in the application of innovative techniques for sustainable design and planning, and energy retrofitting of exi…
