Role of daylight in preserving identities in heritage context

The narrow alleys and the small neighbourhood squares are the most recognisable urban configuration forms that highlight the fabrics of Old Cairo. Parts of Old Cairo are currently going through major conservation projects. The extent of the success of some of these projects in preserving the identity of the Cairene context is currently under scrutiny and has created a debate among local residents, professionals, and politicians. Preliminary investigation has been conducted to assess the rehabilitation strategy of the selected case of el-Darb el-Asfar in relation to its context. Daylight is an essential contextual ingredient that characterises particular places from its counterparts. The rehabilitation project, using new finishing materials, has led to changes in daylight levels and reflections in the space and hence modify the visual perception and the identity of the place itself. This paper aims to assess the impact of the proposed intervention on the visual perception and the identity of the selected built heritage. Daylight variables in open spaces, a combination of sunlight, skylight and the reflected light from the facades and the ground, are identified. Using TOWNSCOPE, daylight's components are calculated pre and after the implementation of the project. The performance of reflected component is traced by simulating the impact of the original and recently used materials. The paper concludes by suggesting a set of measures to achieve an appropriate daylight performance to achieve a sustainable development in the area and maintain the identity of the old city.

Daylight for sustainable regeneration of built heritage sites

Daylight is an essential contextual ingredient of place making. Research in daylighting has recently received major attention for its valuable contribution to the sustainability of the built environment. Previous research has investigated the role of daylighting in energy efficiency, its regional qualities in relation to the façade configuration, and its contribution to the sense of visual comfort. This paper argues that appropriate use of daylighting will ensure not only visual and thermal comfort in an urban setting, but also contributes to the place identity and hence sustainability of urban regeneration projects. The paper identifies the daylight variables that affect the success of the regeneration of heritage sites in Eastern Mediterranean. Daylight variables in public open spaces include a combination of sunlight, skylight and the reflected light from the facades and the ground. The Solar altitude, the geometry of sectional profiles, the reflectance of the opposing facades, the width of the street and the density of the urban built environment are examined to simulate the daylight performance in the selected heritage sites. Located in the historical Darb al-Ahmar district, Aslam Square is selected as part of one of the rehabilitation project in Cairo. This paper examines the photometric and morphological properties of the existing configuration using daylight simulation software. Various spherical projections were developed to represent full 3D visual environment. The paper calculates and analyses the direct radiation energy, the sky diffused energy and the reflected energy in the case study.

Daylight for sustainable development of historic sites

Consideration of daylight is one of the contextual ingredients for maintaining a sustainable identity when intervening in a heritage site. Appropriate consideration of daylighting ensures not only visual and thermal comfort in the urban setting, but also contributes to the preservation of the place visual identity. The historic district of el Darb al-Asfar is undergoing a rehabilitation project that raises questions about the new ‘sparking’ look of the place. The ongoing cultural debate in old Cairo on the extent of success of the rehabilitation efforts in preserving the place identity identified a gap in literature regarding the ingredients that constitute identity in heritage settings. The paper argues that the project using new finishing materials of facades has led to changes in daylight levels in the space and hence the visual perception of the place itself. This paper aims to assess the impact of such intervention on the visual perception and the space identity. A digital model is built utilising a combination of photogrammetric and 3D digital technique. The TOWNSCOPE simulation package is used to trace the performance of direct, diffused, and reflected components of daylight within the original and recently resorted scenes. The output of the simulation exercise has been validated by empirical data. The paper concludes by suggesting a set of measures for achieving an appropriate daylight performance in heritage sites Eastern Mediterranean climatic conditions.

Study on the visual performance of a vernacular dwelling in Egypt

Vernacular dwelling buildings located in hot arid regions are well known for their sensitive architecture response to the region’s climatic conditions and the socio-cultural norms. The architectural value of these buildings is not only limited to their historical merit, but also to the human conscious adaptation to its context and the optimum utilisation of natural resources creating both a pleasant and a functional environment. The majority of these traditional dwellings are well recognised for their unique perforated fenestration system and courtyard arrangement that evolved to control the harsh solar, climatic conditions without compromising the quality of space and occupants’ wellbeing. However, the successful design of these features and solutions cannot be fully appreciated without understanding the nature of daylight and solar radiation in which these buildings are revealed. This paper investigates the impact of the characteristic of the dense narrow streets of medieval cities on the visual performance of a typical courtyard house in Cairo.The paper examines the daylight  behaviour of one of the well-known historic alleys and of a courtyard house in Cairo. The paper analyzes and measures the variability in the visual perception and comfort for a typical pedestrian street and the occupants of the house using a simulation modelling tool (Integrated Environmental Solutions (IES) software). The paper gives an insight into the overall visual performance of the urban fabric that shapes of the microclimate, which is an important ingredient of the overall identity of the place.

The suburbanisation of the coastal communities of Sorrento and Queenscliff : measuring the effects of overdevelopment.

Architecture is often read as a marker of change. The Victorian towns of Sorrento and Queenscliff are undergoing immense change as a result of rapid modernisation and building due to the ‘sea-change’ phenomenon. It has been argued that this is adversely affecting place, diminishing ‘sense of place’, destroying neighbourhood character and leading to unsustainable development. Planning strategies such as Melbourne 2030 have exacerbated this trend by advocating increasing population densities without regard to specific local environmental or historical conditions. Richard Neville comments generally that ‘Architecture is a lightning rod for passions about community, development, taste and lifestyle. Few issues engage and enrage people more than development – whether a prominent public site … or a more local issue such as housing design or density.’ Anecdotally the increase in building footprint is one measure of cultural lifestyle change that has occurred in the last half century in the coastal areas of the Mornington and Bellarine Peninsulas. While the change from the 1950s ‘fibro shack’ to the 2000s supersize ‘McMansion’ in Sorrento and Queenscliff demonstrates increasing prosperity and sophistication, these developments show little awareness of the local coastal landscape or place identity. If the impacts of this ‘sea change’ phenomenon on place are to be considered as more than anecdotal, ways of evaluating these impacts are required. Monitoring and documenting the impact of changes to place will enable the researchers to quantify overdevelopment as site specific and recommend that modern planning schemes need to value and address place differently.

Study on the visual performance of a traditional residential neighborhood in Old Cairo

Traditional dwellings located in the hot arid zone in Egypt are well known for their sensitive architectural response to the region's climatic conditions and socio-cultural norms. The majority of these dwellings are well recognized for their courtyard arrangement and perforated fenestration systems that evolved to control the harsh solar, climatic conditions without compromising the aesthetic quality of the space and the occupants' well-being. The unique visual characteristics of these structures cannot be fully appreciated by assessing the visual performance of buildings in isolation from their urban context. Much of the character of the traditional urban fabric of this region came from the collective visual perception of its architectural components as well as urban patterns. This paper examines daylight behavior of a well-known historic alleyway and of a courtyard house in the Old City of Cairo. Using the Radiance IES simulation modeling tool and a scaled model under an artificial sky dome, the paper investigates the visual comfort in a typical pedestrian street and a selected house. A comparative analysis between simulated results and measured values at target points was conducted. The results indicate a reasonable agreement with the simulation results. The paper gives an insight into the overall visual experience in the traditional settlements in the Old City of Cairo in relation to daylight components and hence their contribution to the unique sense of identity of the place.

De vilarejo a cidade: identidade de lugar de moradores nativos de Tibau do Sul-RN

This study aimed to analyze some indicators of the restructuring process of place identity of natives resident in Tibau do Sul, a coastal town in the state of Rio Grande do Norte state, in relation to changes occurring in this locale in the last few decades. The concept of place identity a complex psychological structure in constant process of restructuring stresses the focus of this analysis on the aspects referring to the relationships of people with their physical and social environment throughout the transition process from the former village of fishermen and peasant farmers to the current growing town. Interviews with insider informants on local history were carried out as a preliminary step to getting in touch with the native participants. In total, 29 native local residents were interviewed, according to a wide range of personal and professional roles, focusing on their cognitions in regard to their past and present relationships with this context, as well as those related to expectancy for the future. The analysis focused both on the elements of distinctiveness, continuity, self-esteem and self-efficacy, and on how each of them have been valued (positive or negative). The participants evaluations of themselves and of the locale, as well as their distinctions in relation to others (people and places) were, in general, very positive. Many elements of group and place continuity, and the possibility of the satisfaction of their needs were highlighted positively, especially comparing to similar situations in the past. The development of the town, related to tourism as well as to other former economic activities, seemed to contribute to the restructuring process of place identity in a way of achieving desirable states for its structure. The broadening of the analysis to consider a wider spatial and temporal context, however, shows that such positive evaluation can be said to hinder some coping strategies of local residents faced with unsustainable economic activities, oftentimes handled to favor a minority of the population

Põe tapioca, põe farinha d’água?: gastronomia do açaí e identidade socioespacial e cultural na Grande Belém

O presente trabalho teve como objetivo principal analisar as mudanças nas formas de venda e consumo do açaí na Região Metropolitana de Belém (RMB), e sua relação com a identidade de lugar de seus consumidores. O interesse pelo tema teve origem na observação da ocorrência da globalização do açaí, alimento base da dieta das populações amazônicas de origem ribeirinha que hoje é largamente consumido fora da Região Amazônica, em padrões muito diferentes daqueles nela estabelecidos. A escolha da RMB como lócus de pesquisa se justifica pelo fato de que nela se concentra alto consumo de açaí, nos padrões tradicionais e nos modernos, suscitando questionamentos sobre os efeitos dessa convivência na vida cotidiana dos que a habitam. Teoricamente, a pesquisa articula a definição de identidade de lugar de Abe-Lima (2012) com as elaborações de Henri Lefèbvre (1991) sobre a vida cotidiana no mundo moderno e com teoria dos circuitos econômicos de Milton Santos (2008). Metodologicamente, foi adotada uma estratégia multimétodos, envolvendo pesquisa documental, um painel de especialistas com 5 entidades de acompanhamento da produção de açaí, observações pautadas na etnografia urbana em 9 locais de venda e entrevistas semiabertas com 40 consumidores de açaí, maiores de 18 anos e residentes na RMB, recrutados por meio de cadeia tipo bola de neve. Além dos roteiros de entrevistas, foram utilizados como estratégias de coleta de dados diários de campo e fotografias. O conjunto dos dados foi submetido à técnica da análise de conteúdo temática, com eventual apoio do software QDA Miner Lite. Os resultados situaram a globalização do açaí em meados da década de 1990, momento de intensificação dos efeitos da metropolização em Belém, como o aumento populacional, a segregação espacial e a imposição de um ritmo de vida mais acelerado. As análises apontaram que tal processo significou a entrada do açaí no circuito superior da economia, com um processo produtivo mais organizado, utilizando mais tecnologia e envolvendo maiores volumes financeiros, atingindo escala industrial. No entanto, prevalece na RMB o processamento artesanal, em estruturas de pequeno porte, construídas em alvenaria, de organização simples e controle financeiro ausente. O consumo público aumentou, com grande número de locais especializados na oferta de açaí, em caráter de entretenimento, sendo incipiente a adesão a novos acompanhamentos, como granola e aveia. A preferência pelos acompanhamentos tradicionais, como farinha d’água ou de tapioca, açúcar e peixe, permanece, assim como pelo consumo privado, no âmbito da casa, que tem sido favorecido pela disponibilidade do serviço de entrega, recurso recente. A frequência geral de consumo diminuiu, em função do aumento de preço e de mudanças na rotina, como aumento da distância entre local de trabalho e residência. A pesquisa permitiu reafirmar a importância do açaí na vida cotidiana dos belenenses que o consomem, para os quais ele funciona como elemento de distintividade, continuidade, autoestima e autoeficácia, em estreita relação com aspectos próprios da metrópole. Por esse motivo, torna-se preocupante que o acesso a açaí de qualidade, nos padrões desejados pelos indivíduos, esteja tornando-SE privilégio inacessível aos consumidores de menor poder aquisitivo. Assim, espera-se que o conjunto de dados contribua para a compreensão da importância de políticas públicas voltadas ao açaí que considerem melhor as demandas daqueles que o consomem.

L’abitare come relazione sociale: il significato della casa e i processi di coesione sociale di vicinato

Se le trasformazioni sociali in atto tendono a esasperare il senso di incertezza, sradicamento ed individualismo, sussistono pratiche che si contrappongono alle tendenze dominanti, finalizzate a ricucire i legami sociali su scala locale. La progettazione urbano-architettonica interiorizza il nuovo bisogno di comunità originando soluzioni abitative tese a favorire gli scambi informali fra vicini, facendo leva sul concetto di capitale sociale, attaccamento al quartiere, identità del luogo e partecipazione. La casa, simbolo di stabilità e sicurezza ma anche di privacy, privatismo familiare, diventa sempre più oggetto di studi, domanda sociale e intervento politico. Soprattutto è sempre più intesa come un nodo di relazioni familiari in una rete di relazioni sociali più ampie. Casa e quartiere incidono nella esperienza di benessere e socialità familiare? In che modo gli spazi urbani e architettonici influenzano la coesione sociale? Quale il ruolo degli abitanti nello sviluppare socialità e integrazione? Sono queste le domande che ci siamo posti per rilevare le dinamiche sociali e culturali dell’abitare attraverso uno studio di caso condotto in due quartieri simili. Dalla ricerca emerge come il significato della casa non sia univoco ma cambi rispetto al ciclo di vita familiare e a quello economico e ciò incide nella partecipazione alle attività di quartiere. Mostriamo inoltre come lo spazio fisico costruito crea importanti opportunità per gli scambi informali e per il benessere familiare e individuale dei bambini ma che, il contesto sociale sia una discriminate fondamentale. Nel quartiere dove è presente una organizzazione di abitanti il numero delle relazioni di vicinato aumenta, cambiano anche la qualità delle relazioni e le distanze fisiche fra i vicini. Emerge inoltre che la reciprocità è il principale strumento di costruzione della coesione comunitaria interna e crea un atteggiamento di apertura e fiducia che va al di là dei confini di quartiere.

Fenomeni di transizione degli organismi edilizi, criteri operativi di inserimento ambientale e procedure di intervento

La presente tesi indaga le potenzialità, in termini di criteri operativi di inserimento ambientale e procedure di intervento, che possono derivare dall’analisi dei fenomeni insediativi facendo riferimento ai concetti di ‘transizione’ e ‘resilienza’. L’attuale periodo di crisi sembra scaturire dal disequilibrio di due fattori: le esigenze umane e l’ambiente. La contestualizzazione degli interventi, il graduale adattamento alle risorse ambientali locali e la valorizzazione dei processi “dal basso” sembrano consentire di riappropriarsi sia del valore identitario dei luoghi, dando risposta ai problemi di natura sociale evidenziati, sia della eco-compatibilità delle trasformazioni, del corretto utilizzo delle risorse energetiche e della gestione delle dinamiche economiche, in risposta ai problemi ambientali analizzati. Il prefigurare applicazioni pratiche del modello di trasformazione indagato alla scala edilizia, utilizzando tavole parametriche di analisi del costruito, viste d’insieme planivolumetriche ed elaborazioni di dati e immagini, può consentire la gestione di eventuali fasi di programmazione e di pianificazione da parte delle amministrazioni finalizzate a favorire e non ostacolare i presenti e futuri fenomeni di transizione. Particolarmente significativa appare l’analisi delle diverse tendenze di ricerca progettuale in atto, con riferimento a contributi caratterizzati da un’impostazione fenomenologica e tipo-morfologica, che dimostra l’attualità degli argomenti affrontati. La ricerca di Dottorato si conclude con l’applicazione dei criteri operativi di inserimento ambientale e delle procedure di intervento individuati ad uno specifico caso di studio.

National education as a 'civics' literacy in a globalized world: The challenges facing education in Singapore

In this paper we discuss the idea of national education in Singapore. National education, broadly speaking, is a civics programme which seeks to instil a sense of place, identity and history in young Singaporeans with a view to developing national pride and commitment. We set this discussion against the backdrop of globalization and the idea of wired communities and argue that any civics programme needs to be more than simply a nationalistic agenda. To do this we have framed national education in Singapore as a civics literacy informed by the idea of multiliteracies. In doing so, we suggest that the pedagogical work of such an approach can help to sustain the nation state of Singapore yet place the civics agenda on a global stage where national education might be seen more appropriately as global education.

I want out of the labels : how Chuck Palahniuk's characters challenge the dominant discourse

The purpose of this study was to explore postmodern identity in the work of Chuck Palahniuk. The characters within Palahniuk's text Invisible Monsters realize the manner in which identity is a construct, and their response is to oppose and redefine it. In my research, I looked at how postmodern identity is defined by some of the leading critical thinkers in the field, and then I applied their thought to Palahniuk's characters. I showed how these characters come to understand the process by which society defines them, and with that realization, they oppose its totalizing definitions. The characters deconstruct the natural attitudes society has towards identity, and they reveal that it is in some way possible to create a unique identity that is not easily definable by the ruling discourse. I concluded that his attention to identity highlights Palahniuk's concern for the place, identity, and influence of his generation.
