Resilience best practice: technical data sheets for essential temporary housing
No full textSeveral elements of social and demographic hazards, such as adverse economic conditions, resource
shortage, climate change, and growing immigration flows are affecting the stability of cities.
Conventional urban planning lacks adequate emergency responses and struggles to find fast, low-cost
solutions to cope with the absence of urban structures and houses. Indeed, the housing sector is one
of the action areas considered by what is known as a City Resilience Framework to be essential in
improving urban resilience. The latter is a study on existing resilience requirements that began as a
Ph.D. thesis and actually focuses on the parallels between the informal and the resilient city. It
analyzed 19 case studies and borrowed examples of resilience from them in order to draft a framework
of technical indications for essential, new, and temporary housing construction. The resulting
“Technical Data Sheets for the Design” offer technological, typological, functional, and procedural
information to be applied in preventive planning in order to promote resiliency
Strategie progettuali della Material Efficiency per la transizione circolare.
No full textLa storia della leggerezza potrebbe raccontare non più solo di aeroplani
e materiali a bassa densità, ma anche di una esigenza di dematerializzazione
coerente con il controllo del consumo di risorse e delle emissioni di gas
climalteranti (GHGs). Dall’Accordo di Parigi, le politiche per la neutralità carbonica
si sono focalizzate inizialmente sulle azioni di mitigazione per l’efficienza
energetica e sulle fonti low-carbon. Sebbene cruciali per l’industria dei materiali,
altre strategie sul lato della domanda sono possibili per ridurne la produzione.
Nell’ambito dell’economia circolare applicata all’ambiente costruito, la Material
Efficiency (ME) costituisce un insieme di azioni per il circular design per le quali
occorre reinventare funzioni, configurazioni e processi costruttivi
Buildings and proximity open spaces for energy transition. A testing on Renewable Energy Communities in Rome
No full textThe transition to a sustainable urban energy
system is one of the conditions for mitigation
and achieving a zero-emission economy. Cities
and their inhabitants represent an important
potential to reduce energy consumption and
climate-changing emissions, due in part to their
diversity, dimensional variety and urban
pattern. However, energy transition studies
have focused insufficient attention on the issues
related to space, place and scale, and how these
can shape different energy systems.
Through pilot cases in Rome, the article
addresses subject of Renewable Energy
Communities in the urban context, presenting
the first results of research that, with the aim of
testing, in proximity spaces, solutions for
mitigation and adaptation to the climate change
effects, investigates how the organization of
urban built-up districts and environmental and
social resources can influence the decentralized
energy system and vice versa
Occupazioni illegali di edifici pubblici quali modelli legittimi di coabitazione
No full textCrisi economica, migrazioni costanti e scarsità di risposte
di edilizia sociale stanno portando un sempre più
ampio segmento della popolazione verso l’emergenza
abitativa che, senza soluzioni istituzionali e a basso costo,
trova nell’abusivismo l’unica possibile rapida risposta.
Le occupazioni informali rappresentano una soluzione,
benché limitata nel tempo, per il soddisfacimento
dell’esigenza primaria abitativa. Le autrici ritengono
che dallo studio dei modelli applicati in queste situazioni
di emergenza possano scaturire modelli organizzativi
e progettuali per definire una nuova normativa residenziale.
Questo contributo illustra il caso di studio Spin
Time Labs, occupazione di un edificio pubblico nel centro
storico della città di Roma e modello di coabitazione
temporanea, attivatore di rigenerazione urbana.Economic crises, continuous migration and insufficient
social housing responses are leading an ever-widening
segment of the population towards a housing emergency.
Due to the lack of institutional or affordable solutions,
squatting becomes the only option that is both viable
and immediate. Informal occupations, although timelimited,
are an answer to satisfy the primary housing
need. In studying the patterns used in these urgent situations,
the authors consider the emergence of organisational
and design models that can facilitate defining a
new residential legislation. This contribution illustrates
the case study of Spin Time Labs. Located in an occupied
public building in Rome’s historical centre, Spin
Time Labs is a temporary cohabitation model and an urban
regeneration catalyst
HOUSING EMERGENCY: REQUIREMENTS OF RESILIENCE
No full textThe demographic pressure and the gradual urbanization in large cities determine constant
housing problems.
In addition to a growing and continuous immigration flow of foreigners headed towards the
metropolises in search of better life conditions, there is also the section of the population who,
due to a lack of income, or poor economic conditions, have no access to real estate market,
not even to rented houses.
In absence of quick responses, which fall in the common urban planning, the housing emergency
puts the population in poor condition and turns into self-managed and informal responses
which in turn become emergency.
Although with different dimensions with respect to the megacities in the World, the Italian case
presents common characteristics that, in absence of suitable preventive methods, prefigure an
informal city growth.
The city, a heterogeneous context that is subjected to sudden and chronic emergencies,
requires flexibility and capability of adjustment to the variable conditions of all the urban
systems. Therefore, the reference is to the concept of “resilience”, borrowed by the ecological
approach and declined in several disciplines, as a thin border between flexibility and robustness,
stasis and evolution, change of state and balance (Holling, 1973).
Considering the resilience like the sum of coordinated processes, which increase the adjustment
of the city and its inhabitants, the research investigates about what kind of contribution can
be given by architecture to the overall resilience strategy. It examines whether there are some
characteristic features (technological, typological, functional, procedural), for essential housing
models which, once applied in a preventive basis since the planning phase, can contribute,
even if indirectly, to the overall urban resilience by cooperating to ensure quick and adaptive
responses, with low construction, management, maintenance costs, and low consumption of
energy and resources
Housing emergency and minimum requirements for reception: contribution to the strategy of resilience
No full textThe population pressure and the massive urban migration to the megacities determine a constant housing discomfort in huge masses of population that, in conditions of great disadvantage, do not have access to housing. Without a quick response the housing crisis results in informal, self-managed solutions that become an emergency themselves. The city is called on to face this chronic stress enhancing its resilience, which also includes housing, as highlighted in the resilience framework. Developing a complex methodology based on the analysis of informal settlements and of case studies designed to prevent them, the present study investigates the possible contribution of architecture to the above framework and if any characterising features exist that, if pre-emptively applied to the project, may favour resilient responses. Taking metadesign as a reference, and after outlining the characterising features, the present study drafts a “Framework of technical guidelines for essential new and temporary housing solutions”, structured in “Technical sheets for planning” aimed at helping all the players involved in design processes reach resilient outcomes

No full textRhOME for denCity, il progetto del team di Roma3, vincitore del Solar Decathlon 2014, tra le altre innovazioni messe a punto per la gara svoltasi a Versailles nello scorso luglio, ha come punto di forza l’utilizzo innovativo della massa per migliorare l’efficienza termica degli edifici.
Già intrapreso dallo stesso gruppo di ricerca per la precedente edizione, con il progetto Med in Italy, il tema della valutazione del contributo della massa termica, cerca questa volta un mag- giore approfondimento.
Progettato prevalentemente per i climi mediterranei, il proto- tipo RhOME cerca, attraverso una ricerca puntuale, di fare sin- tesi tra innovazione tecnologica e integrazione architettonica, con l’obiettivo di dare a un edificio in legno, tradizionalmente “leggero”, il beneficio termico degli edifici “pesanti” caratteri- stici dei climi caldi.
L’obiettivo principale del team RhOME è stato quello di muo- versi al confine tra intuizione della strategia e validazione della stessa attraverso l’utilizzo mirato e sinergico di più strumenti di simulazione e di prove sperimentali.
Fin dalle prime battute del progetto, quindi, il team ha lavorato
contemporaneamente sull’integrazione dello strato di massa termica e sulla simulazione di come questo strato di sabbia fosse in grado di influenzare in qualche modo il microclima in- terno degli ambienti, riducendo di conseguenza il dispendio energetico dovuto all’utilizzo degli impianti di riscaldamento e raffrescamento.
Lo strato di massa termica previsto è stato integrato nella co- struzione addizionando, sul lato interno della parete perimetrale, un layer di sabbia sfusa contenuta, ai fini della competizione, in tubi di alluminio (vedi tabella e disegno a pag. 88).
Lo studio scientifico sulla massa termica molto spesso è inteso solo come focus sul comportamento termico della parete, vir- tuoso involucro di separazione tra interno ed esterno, in cui la massa contribuisce a rallentare il passaggio dell’onda termica attraverso la parete.
In questo caso, invece, l’intento del team di ricerca è stato quello di studiare, indagandone le dinamiche, il contributo della massa termica non come cesura tra interno ed esterno, ma come assorbitore termico interno, con il ruolo di smorzare le oscillazioni di temperatura all’interno dell’abitazione.Rhome for Dencity, the project of the team Roma3, winner of the Solar Decathlon 2014, among other innovations developed for the race held in Versailles last July, has the strength of the innovative use of mass to improve thermal efficiency of buildings.
Already undertaken by the same group of research for the previous edition, with the project Med in Italy, the question of the evaluation of the contribution of thermal mass, this time seeking a greater depth.
Designed mainly for Mediterranean climates, the prototype Rhome search through a detailed research, to make synthesis between technological innovation and architectural integration, with the aim of giving a wooden building, traditionally "light", the benefit of "heavy" buildings, characteristic of warm climates.
The main objective of the team Rhome was to move the boundary between intuition and validation of the strategy of the same through the use of more targeted and synergistic simulation tools and experimental tests.Right from the start of the project, then, the team has worked
At the same time on the integration of the layer of thermal mass and on the simulation of how this layer of sand was able to somehow influence the microclimate of procedure of the environments, thereby reducing the energy consumption due to the use of heating and cooling .
The layer of thermal mass provided, has been integrated in the construction by adding, on the inner side of the peripheral wall, a layer of sand, bulk contained, for purposes of competition, in aluminum tubing
The scientific study on the thermal mass is very often understood only as a focus on the thermal behavior of the wall, virtuous casing separation between inside and outside, in which the mass helps to slow down the passage of the thermal wave through the wall.
In this case, however, the intent of the research team was to study the contribution of thermal mass not as break between indoors and outdoors, but as a heat absorber inside the house, with the role of dampen oscillations temperature inside the dwelling
