Adaptive facades are performance based envelopes that are able to respond dynamically to climatic conditions. One of the recognized adaptive façade technologies is electrochromic glazing. However, very few studies evaluated the performance of electrochromic glazing on the building level. Therefore, we selected a case study of a certified educational building with a nearly zero energy building performance that includes an electrochromic facade. The overall aim of the research is to understand the performance requirements of electrochromic glazing and its overall contribution to energy saving s and thermal and visual comfort improvement. The performance of the Swiss International School in Dubai was analyzed based on interviews with the design and build team, monitored data and post occupancy evaluation. A systematic process mapping took place to review the performance indicators, simulation tools and team responsibilities during the design, construction and operation stages of the building. The paper identifies the key performance criteria of electrochromic glazing in relation to energy and comfort. Finally, we assess the significance of using electrochromic glazing from a technical point of view and share the learned lessons for architects and facade engineers [less ▲]

Assorti d’une série de textes inédits, cet ouvrage monographique vise à faire connaître dans le milieu francophone les écrits d’Aby Warburg (1866-1929), en particulier ceux rédigés dans les dernières années de sa vie. Peu connus, ces textes datent de la période d’élaboration de l’Atlas d’images Mnemosyne – Atlas dont le succès grandissant auprès des artistes et des théoriciens de l’art n’est plus à démontrer . Mais si Mnemosyne attire de plus en plus les spécialistes des images de tous horizons, on accorde encore peu d’intérêt aux textes et aux notes rédigées par son auteur dans les années 1926-1929. Ces textes auraient du accompagner les planches de l’Atlas si le projet avait abouti. Or, les manuscrits inédits conservés au Warburg Institute (Londres) montrent la portée philosophique des recherches tardives d’Aby Warburg. Il y développe une théorie culturelle de l’image pour le moins originale et qui a profondément influencé certaines démarches plus contemporaines (dans les domaines de l’histoire de l’art, de l’anthropologie du visuel, de la Bildwissenschaft allemande ou des Visual Studies anglo-saxonnes). À l’occasion d’un débat avec les pensées de Nietzsche et de Burckhardt, Warburg élabore une conception nouvelle de la Kultur. [less ▲]

Adaptive facades can ensure step-change progresses in the energy efficiency and the use of renewable energy while improving the comfort of the occupants. Therefore, the purpose of this structured interview is to assess advantages, disadvantages and future expectations considering the adaptive facades. This work is a part of actions of The COST Action TU1403 Adaptive Façade Network. The objective of this report is to gain an understanding of how experts currently define adaptive façade systems, which simulation tools they use, the major strengths, weaknesses, opportunities and treats of adaptive façade systems, key performance indicators they use and their vision for the future of adaptive facades. With this information gathered, it is anticipated that adaptive façade professionals will carry on assessment of adaptive facades. A qualitative study design was employed, using semi-structured interviews. Interviewees working in academia and practice were selected. The interviewees represented the range of possible adaptive facade professionals, from researchers and designers considered optimization in the assessment of adaptive facades. Also, every interviewed expert was asked to approve their responses and add any additional comment to their answers. [less ▲]

According to Jennifer A. Peeples, the “toxic sublime” refers to “the tensions that arise from recognizing the toxicity of a place, object or situation, while simultaneously appreciating its mystery, magnificence and ability to inspire awe”. As an alternative to the “technological sublime”, which creates awe through the contemplation of human efforts to master the environment, it urges us to consider the negative and noxious aspects of such endeavours. Through her analysis of Edward Burtynsky’s “Manufactured Landscapes”, Peeples introduces a new form of sublime aesthetics, which may also be used as a valuable trope in the study of the relationship between literature and our physical environment. My goal in this study is to extend such considerations to the recent history of American literature, using examples such as Rachel Carson’s “A Fable for Tomorrow” (1962), which describes the invisible “lethal film” made of “systemic insecticides” that converts natural species into carcinogenic poison, thus depicting landscapes as intoxicated “places of beauty” that no longer symbolise human abilities to dominate the environment but rather their lack of control over it. Likewise, in Don DeLillo’s novel White Noise (1985), the protagonist Jack Gladney experiences his daughter’s “utterance” of the car brand “Toyota Celica” as “beautiful and mysterious”, which “str[ikes] [him] with the impact of a moment of splendid transcendence”. Gladney then proceeds to relate his family’s “garbage” to his relatives’ selves as it is a “sign[] of [their] deepest nature”. Jack’s approach to human waste shows that what Cynthia Deitering defines as the “toxic consciousness”—the general awareness of the existence of toxicity in the landscape—is to be associated with the protagonist’s idea of “consumer consciousness”. Indeed, the term toxicity can also metaphorically refer to the “poisoned” nature of our relationship to and perception of specific places, objects, or situations. The viewer in national parks, for instance, tends to see the “sublime landscape” as a “series of picturesque scenes”, which allows him to consume the scene as an “object of artistic consumption”. Such examples point to different but related ways of examining distinct forms of toxicity that characterise our relationship with our physical environment. They also prompt us to examine the problematic nature of technology and progress while dealing with the elusive and paradoxical nature of the technological sublime. [less ▲]

In the wake of financial and economic crises, the European Union took unprecedented steps to build an institutional framework accompanying financial market governance. This chapter will outline the EU law techniques used to integrate Member States’ interests in the set-up and functioning of that framework. Following a brief overview and recapitulation of the ‘more Europe’ developments having taken shape in the wake of crisis, the chapter will proceed in summarising how Member States’ interests have been embedded directly within the post-crisis EU regulation framework. It will be submitted that two different and complementary kinds of ‘interest inclusion’ techniques can be distilled, more or less explicitly, within the newly created financial market supervision frameworks. The inclusion and presumed safeguarding of Member States’ interests by virtue of administrative law tools is not entirely unproblematic. The final section of the chapter highlights challenges associated with such interest-inclusion approach and questions whether the a modest way forward in an attempt better to legitimate the current interest inclusion techniques by the EU institutions.

The objective of this paper is to investigate the respective influence of various urban pattern characteristics on inundation flow. A set of 2,000 synthetic urban patterns were generated using an urban procedural model providing locations and shapes of streets and buildings over a square domain of 1 x 1 km². Steady two-dimensional hydraulic computations were performed over the 2,000 urban patterns with identical hydraulic boundary conditions. To run such a large amount of simulations, the computational efficiency of the hydraulic model was improved by using an anisotropic porosity model. This model computes on relatively coarse computational cells, but preserves information from the detailed topographic data through porosity parameters. Relationships between urban characteristics and the computed inundation water depths have been based on multiple linear regressions. Finally, a simple mechanistic model based on two district-scale porosity parameters, combining several urban characteristics, is shown to capture satisfactorily the influence of urban characteristics on inundation water depths. The findings of this study give guidelines for more flood-resilient urban planning. [less ▲]

The paper explores the interaction between different kinds of social agents in the funding and management of cult foundations for the dead in the late-classical and Hellenistic period. Textual and archaeological dossiers will be discussed in order to 1) investigate the occupation of sacred space in existing sanctuaries and other public spaces as well as the creation of new sacred places, specifically meant to host ritual practice for dead individuals or groups; 2) provide a comparative analysis of the patterns of establishment, funding and management of cult foundations pertaining to civic, royal, individual or groups' initiatives; 3) explore the forms of interaction between various agents involved, e.g. between civic and private initiative in funding and management. When possible, these considerations will also be integrated with an evaluation of the religious status attributed to the honoured persons, with particular attention to the semantic fields of heroization and deification. Thus an attempt will be made at tracking down possible general trends of religious administration beyond local particularities, and at schematizing these configurations in a model taking into account four factors: the social status of ritual agents and recipients; the religious status acknowledged to cult recipients; the methods of funding and management; the degree of monumentalization and social impact of the cult foundations.

Structural fire engineering has long relied on a prescriptive approach based on isolated member behavior under continuously heating standard fire. By definition, this approach does not allow comprehending the effects of interaction between members of a complete structure nor the effects of real fire exposure. Yet, such effects can have a significant influence on the response of real buildings to fire. Notably, when a structure has survived a fully developed fire, the cooling phase that inevitably follows generates effects that may endanger the structure stability. This has been attested by real structural collapses and poses a specific threat to firefighters. However, the behavior of structures under natural fire and the causes of failure during cooling are still not well understood. This research investigates the response of steel-framed structures to natural fires with the aim to analyze the possible collapse mechanisms during cooling. Numerical simulations by nonlinear finite element method are conducted for different fire scenarios and structural designs. The simulations model the thermo-mechanical behavior of the frames accounting for the interaction between members during the entire fire duration until burnout. Different collapse mechanisms during cooling are highlighted and discussed, including connection failure and progressive collapse under localized fire. In the latter case, collapse of members not directly affected by the fire occurs during the cooling phase. These mechanisms result from a complex combination of several factors, such as the recovery of thermal elongation, the recovery of stiffness, and the prior development of permanent strains in the heated members. The results show that steel-framed structures are subject to collapse during the cooling phase of natural fires. Therefore, natural fires with heating-cooling sequences represent a loading case that should be considered in structural fire analyses and could lead to specific design provisions to prevent the occurrence of collapse during cooling.

Charcoal production in forests is one of the oldest forms of forest exploitation. The legacy of such once widespread activity is a plethora of relic charcoal hearths (RCHs1), where soil shows a thick, black, charcoal-rich top horizon. Even where very common, such as in European forests, RCHs were rarely studied to assess their relevance as C reservoir. For this purpose, as a case study, we investigated some RCHs at Marsiliana, a typical Mediterranean oak forest from Central Italy. We found that RCHs soils, in spite of representing < 0.5% of total surface, gave a substantial contribution in terms of C, i.e. 1.1% to 4.2% of total ecosystem C, including litter, the top 30 cm of soil, deadwood, above-ground and below-ground biomass. On average, soil C content in RCHs was eight times higher than the soil outside the RCHs. The environmental significance of RCHs soils appears still greater considering that, on average, 43% of their C stock was charcoal, a form of C highly recalcitrant to mineralization. These results would stress the importance of accounting for the contribution of RCHs in terms of soil C and giving an estimation of their charcoal content in future C inventories, both as macroscopic and microscopic particles in soil. This study support the necessity of safeguarding the anthropogenic soils of RCHs as a precious C reservoir as well as a memory of past land uses. [less ▲]

Les études consacrées aux interventions de Sartre dans les médias dressent le portrait d’un philosophe frileux à l’égard de la radio, un médium réputé « à sens unique » conformément aux commentaires qu’il en aurait livré dans sa Critique de la raison dialectique. Il n’est pas étonnant dès lors que ces études se satisfont d’une approche essentiellement textuelle de ces interventions et manquent ainsi les usages singuliers que Sartre a fait de ses passages en radio. Partant d’extraits d’interventions enregistrées entre 1946 et 1973, la conférence et projection sonore Réagir à l’archive. Sartre et la radio entend contester l’image d’un philosophe rétif au médium radiophonique tout en dépassant la réduction de ses interventions sonores à leur seule retranscription textuelle. Le rythme des réponses du penseur, leur longueur, le jeu avec l’interviewer dont elles portent les traces, mais aussi les multiples références au direct de l’entretien radiophonique et à la réalité du moment de la diffusion témoignent en effet d’un usage extrêmement lucide d’un médium dont Sartre a tenté d’exploiter toutes les potentialités intellectuelles et politiques propres. On découvrira ainsi qu’avant d’être un matériau d’archive effacé par le texte, les interventions radiodiffusées du philosophe ont été autant de tentatives de (se) jouer de la spécificité radiophonique pour inscrire la pensée critique au cœur même du dispositif médiatique.
