Adattarsi al clima che cambia. Innovare la conoscenza per il progetto ambientale / Adapting to the Changing Climate. Knowledge Innovation for Environmental Design
No full textLe conseguenze del cambiamento climatico impongono di innovare i metodi del progetto ambientale alla luce di più complessi approcci al sistema di produzione della conoscenza, anche integrando alla scala meta-progettuale strategie e azioni al fine di garantire più efficaci contributi ai processi di riduzione del rischio, sui quali convergono le raccomandazioni e le politiche di numerosi organismi internazionali e nazionali.
Il volume Adattarsi al clima che cambia. Innovare la conoscenza per il progetto ambientale, rappresenta il primo dei due libri che restituiscono il lavoro scientifico della ricerca PRIN 2015 Adaptive design e innovazioni tecnologiche per la rigenerazione resiliente dei distretti urbani in regime di cambiamento climatico, condotta dalle Unità di Ricerca delle Sedi di Università degli Studi di Napoli Federico II, Politecnico di Milano, Sapienza Università di Roma, Università degli Studi della Campania Luigi Vanvitelli, Università degli Studi di Firenze, Università degli Studi Mediterranea di Reggio Calabria. La ricerca ha posto al centro dello studio la ri-definizione del quadro teorico e metodologico per il progetto di adattamento climatico, individuando nella dimensione inter-scalare e sistemica le chiavi di accesso per una strategia di azione finalizzata alla sfida climatica in specifici contesti urbani italiani.
Partendo da questo punto di vista, il volume inquadra in modo integrato i processi e gli strumenti della conoscenza attraverso i quali affrontare la gestione dei topics analitico-interpretativi a supporto del progetto di adaptive design, puntando ad integrare i metodi di ricerca quantitativi (incentrati sulle azioni di definizione del campo di intervento, misura e sperimentazione) con quelli dell’euristica, per la ricerca di soluzioni creative e site-specific. Un sistema di indicatori per il monitoraggio e la misura di valori di fondo del contesto di riferimento definisce sia le condizioni di criticità legate agli impatti climatici, sia gli esiti ex-post degli interventi di rigenerazione urbana. Conclude il volume una lettura critica di casi scuola internazionali e nazionali, dai quali sono state evinte prassi efficaci, trasferibili e applicabili ai contesti nazionali in ragione dei livelli interscalari utilizzati
Resilience and technological culture of design: the centrality of method
No full textThe article aims at depicting the main scientific points of the resilience debate within the field of the Architecture Tecnology. The contribution identifies into the formula “the method-as-research question" the theoretical roots of the technological culture specific, that is a prime condition for architecture, and a milestone for governing the common scientific results. According to this premise, the article aims at demonstrating the existence of a strongly consolidated design praxis within the disciplinary tradition that allows to continuously review research objectives and cognitive tools, effectively updating the theoretical apparatus. In order to enhance such approach, the article claims the advanced position of architecture technology with respect to the concept of resilience, and it focuses on the disciplinary capacity of adapting research questions to the design responses. Notably, the contribution emphasizes the performance-based design approach as a further methodological skill, typically referable to the discipline, that is a logical key to frame the resilience demand within the systemic condition of the design adaptation and / or mitigation projects
Simultaneous cycle sequencing assessment of (TG)m and Tn tract length in CFTR gene
No full textThe lengths of the dinucleotide (TG)m and mononucleotide Tn repeats, both located at the intron 8/exon 9 splice acceptor site
of the cystic fibrosis transmembrane conductance regulator (CFTR) gene whose mutations cause cystic fibrosis (CF), have been shown to influence the skipping of exon 9 in CFTR mRNA. This exon 9-skipped mRNA encodes a nonfunctional protein and is associated with various clinical manifestations in CF. As a result of growing interestin these repeats, several assessment methods
have been developed, most of which are, however, cumbersome, multi-step, and time consuming. Here, we describe a rapid
method for the simultaneous assessment of the lengths of both (TG)m and Tn repeats, based on a nonradioactive cycle sequencing procedure that can be performed even without
DNA extraction. This method determines the lengths of the (TG)mand Tn tracts of both alleles, which in our samples ranged
from TG8 to TG12 in the presence of T5, T7, and T9 alleles, and also fully assesses the aplotypes. In addition, the repeats in the
majority of these samples can be assessed by single-strand sequencing, with no need to sequence the other strand, thereby saving a considerable amount of time and effort
Less Energy, More Quality. From Leipzig Charta to 2010/31/Ue Directive
No full textTechnology is all geared to "Zero Energy Building " (in accordance with the EPBD Recast: 2010/31/UE Directive) acting especially on the envelope: less energy and other resources's needs and more use of eco-friendly materials, in order to guarantee appropriate performance (without energy sacrifice!) for heating, domestic hot water, cooling, natural ventilation and lighting. All because: "Europe needs cities where life is good!".
The contribute illustrates a design experience begun during the “Archisostenibile 2010” Workshop organized by the Mediterranean University of Reggio Calabria (urban design phase) and completed at the SUN (building design phase)

Social, economic and environmental sustainability in planning community services.
No full textResiliency and sustainability are not synonymous. Sustainability is a final (and constant) permanent objective, often based on a static vision: resiliency assumes instead a dynamic approach, looking at system transformation pro- cesses to drive its evolution and increase the chance of a sustainable final out- come. So, if the goal is sustainability, resiliency is one of the many ways we have today to obtain it.
Moreover, new effective models in the design phase drive towards shared processes, able to stimulate a bottom up and open source participation, and to involve public debate and consent development; thus, we must encourage propo- sitions, so widespread among citizens, that can drive an economy through a continuous dialogue among stakeholders, institutions, companies and civil society.Thus, we need to make the best use of available resources and skills through a building process and product innovation (economic sustainability) that ensures better and more effective/efficient services as well as positive effects for employment (social sustainability), moving from a linear economy to a circular economy (environmental sustainability).
This requires the adoption of increasingly flexible solutions, able to ensure through time the building quality and their fitting to the changing needs.
Within the disciplinary sector of Architectural Technology, this means to re-establish the conditions for a rational management of planning and design phases, by continuously monitoring the building process until a reliable as- sessment of its outcomes during the practice phase is performed, through Post Occupancy Evaluation procedures able to identify critical issues and dissemi- nate knowledge with reducing the failure risks
Development of Highly Bendable Transparent Window Electrodes Based on MoOx, SnO2, and Au Dielectric/Metal/Dielectric Stacks: Application to Indium Tin Oxide (ITO)-Free Perovskite Solar Cells
No full textIndium-doped tin oxide (ITO) is the transparent conductive material of choice for a wide range of optoelectronic devices such as sensors, light-emitting diodes, and solar cells. However, its brittle nature, high cost, scarcity as well as aggressive deposition via sputtering determine the need to find cheap alternatives with high optical transparency, low sheet resistance, and mechanical flexibility. Dielectric/metal/dielectric (D/M/D) electrodes fulfill all these requirements and are deposited via low embodied energy low-temperature processing. We developed D/M/D multilayered electrodes based on thermally evaporated MoOx or solution-processed SnO2 seed layers, a thermally evaporated ultrathin Au film, and a spin-coated SnO2 top layer on rigid glass substrates. We first systematically unraveled the role of each layer on the resistance-transmittance properties of the full D/M/D electrode structure. By optimizing the thickness of the seed, metal, and the top layer, we obtained electrodes with transmittance of 72% at 550 nm and a minimum sheet resistance of similar to 9 omega sq(-1). Subsequently, these optimized multilayered stacks were employed as bottom electrodes for perovskite solar cells (PSC) with glass/D/M/D/mesoporous-TiO2/CH3NH3PbI3/spiro-MeOTAD/Au device architecture, delivering power conversion efficiencies (PCE) of 10.7%. Further, we deposited and characterized D/M/D electrodes on flexible polyethylene terephthalate (PET) films, achieving a maximum PCE of 7.6%. The difference in performance compared to rigid glass devices can be ascribed to the different wetting of the active layer on PET substrates. Flexible D/M/D electrodes displayed excellent mechanical properties compared to commercial PET/ITO, showing completely stable sheet resistance after repeated bending even down to 1.5 mm of curvature radius, whereas PET/ITO showed one order of magnitude increase in sheet resistance in the same mechanical test, due to formation of cracks in the conductive oxide. Our optimized D/M/D stacks on glass and especially on PET or other types of flexible substrates are therefore excellent alternatives to ITO as transparent window electrodes for low-cost, light-weight, and conformal optoelectronics applications
