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.

Post-war migrant built heritage in Melbourne : from assimilation to multiculturalism

If place identities are created by ascribing subjective meaning to sites and buildings it follows that diverse groups will consider place meaning differently. This poses a challenge for the selection and interpretation of heritage sites in plural societies where notions of architectural significance are likely to conflict. Basing heritage policy on the premise of a shared heritage is particularly challenging when the cultural traditions of the past underlie definitions of architectural significance in a more culturally diverse present. This paper presents an introduction to research exploring the inclusion of twentieth century migrant built heritage in Australia. Through selected examples of recently recognised heritage sites in Melbourne, the paper considers how migrant heritage is included and what this reveals about the cultural traditions underlying Australian heritage discourses. The inclusion of migrant places suggests that there is an initial shift in heritage discourses where notions of architectural significance have expanded to include the history of post-war migration. However, the examples raise questions about the nature of cultural inclusivity in heritage frameworks.

Whose identity? Valuing the culture built heritage in diverse and tensioned societies

The UNESCO declaration on cultural diversity in 2002 has raised more questions than answers. More recent events around the World have highlighted the immediate need for legislative actions to protect cultural built heritage in tensioned societies. This paper discusses the potential global risks that face cultural built Heritage. The paper argues that such risks are not only limited to regions where military operations are taking place but also to nations where questions of identity and cultural diversity are raised. The paper questioned the reasons and the impact of the rise of ethno nationalism on the protection of cultural built heritage. The different discourses of these groups that will lead to destruction of cultural artefacts are also explored. In order to properly legislate means for the protection of vulnerable cultural built heritage in conflict areas, the underline value system should be clarified and the values under threat identified. The paper concludes with a plea to move our understanding and definition of culture from the previous 'old' definition with relation to "people' to a 'new' one which is more relevant to context.

Valuing local built heritage in a global setting : identity & visual perceptions of cultural built heritage in Northern Ireland

‘In these troubled times with the world in search of its bearings and way ward minds using the terms “culture” and “civilization” in an attempt to turn human beings against one another, there is an urgent need to remember how fundamental cultural diversity is to humanity itself’ (UNESCO 2002). The progressive idea of culture can be used in regressive ways by extremists who used it occasionally to pursue the politics of xenophobia and exclusion. The hypothesis that different communities can share the same culture but have different visual perception of their built environment might seems contradictory. It is essential to describe what is meant by the ‘same culture’. The ever evolving changes of definition and re-definition of the word has not yet settled. This paper adopts the descriptive definition of culture while challenging its interpretation. The descriptive definition refers to ‘all the characteristics activities by a people’. While this description is generally accepted, the interpretation of what ‘a people’ means is divisive. It is not clear how Eliot defines ‘a people’. Is the term genetically prescribed or is ‘a people’ place related? And what about the moral and religious orientation? This paper argues that culture is basically place related and the forces that shape a culture of a ‘people’ are deeply embedded in the environmental forces that also shape other aspects of the place making and its identity. The paper addresses the questions of conflicts, value systems, and culture definitions and the inseparable links with architecture aesthetics.

Local built heritage in Northern Ireland is taken as a case study. Unlike many parts of the world, visual perceptions in Northern Ireland is well recognised with iconic as well as formal representations. The population is well aware of the signified as well as the signifiers. The boundaries between iconology and formalism theories are very blurred in the Northern Ireland context. This paper examines how the two communities visually perceive their shared built heritage and the extent of overlapping between the understanding of iconic and formalist visual representations in the built environment. The paper takes the buildings of the successful economic ventures of the shirt industry in the 19th century as a case study. The case study provides an insight of how a signified value of a successful economic regeneration initiative that is deeply imbedded in the social structure and within the urban fabric can overcome divisive visual perception. The paper examines the possibility of building upon the historical success of the shirt industry to promote architectural cultural dialogue in which cultural built heritage in Derry is able to facilitate knowledge creation and social capital in different arenas.

Cross-Territorial heritage sites : towards a cross-cultural heritage practice

This paper will describe a current research project at Deakin University’s Cultural Heritage Centre for Asia and the Pacific which aims to develop our current understanding of heritage beyond the national frame usually given to it. The project focuses on a number of heritage sites associated with Australia’s war time heritage. However, all of these sites are located on foreign soil, in land which is not owned by the Australian government. Moreover, because of their location, these sites may or may not have significance for the countries where they are located or to other participants in the same war. Their location in another country and in other people’s narratives poses a complex problem for those who want to conserve, manage and interpret these sites in a manner which preserves their significance to Australia. Is it possible to do this while also recognising other people’s investment or lack of, in these sites? What do we need to think about when recognising the existence of dissonant heritage not only within a nation but across nations? And can this dissonance be used to encourage crosscultural dialogue? Using current understandings of heritage as potentially dissonant, and accepting the need to work within a pluralist frame which supports and argues for cultural diversity, this project explores what happens when this dissonance and diversity occurs not simply within a nation but across national borders. The paper will explore these issues by looking at the interpretation of the Thai-Burma railway, one of a handful of sites which Australians use to mark Anzac Day, the national day of remembrance for those who died fighting for their country.

Managing industrial world heritage sites : preservation, presentation and sustainability

This thesis uses case study methodology to explore how the concept of sustainable development is being applied at industrial World Heritage sites. The thesis proposes a model of sustainable heritage management that is relevant to industrial heritage sites, as well as to other complex heritage sites, including historic urban landscapes.

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.

Whither sporting heritage : reflections on debates in Victoria about Waverley Park and the Melbourne Cricket Ground

The successful nomination of Waverley Park to the Victorian Historic Register
proved as controversial as the stadium was during its thirty-year existence. The
nomination was accepted primarily on the grounds of the social historical value of the site, rather than its architectural or engineering qualities, but in fact a range of different social histories were in conflict during the registration process. Four of the social histories involved are outlined and their influence on the outcome assessed. Some of the implications for the evaluation of sporting heritage sites emerge therefrom (Hay, R., Lazenby, C., Lewis, N., Haig-Muir, M., Mewett, P., 2001).

Understanding public involvement with Australian heritage : a qualitative study using repertory grid analysis

Attempts to increase public participation in heritage related activities have had mixed success. Tourism to heritage sites remains an overt activity that many engage in, but other heritage related activities, such as nominating objects for formal heritage listing, are much rarer. Through a series of qualitative research activities, we examine the public perceptions of what constitutes "heritage" and "heritage - related" behaviours, in order to examine barriers to greater involvement. The findings are that heritage is important to many people, particularly on a personal level. Although initially uncertain about the validity of their views, our respondents defined heritage broadly, believing it to encompass a wide range of objects, places and experiences. Most respondents were undertaking the type of heritage-related behaviours that heritage managers would encourage, however the respondents did not recognise them as being heritage-related. Barriers to greater involvement include this uncertainty over the definition of heritage and a lack of confidence in their ability to effectively recognise and protect heritage. In addition to feeling uncertain about the heritage significance of their own actions and beliefs, the respondents felt even more uncertain about prescribing things of "national heritage value". This uncertainty stifles discussion and action. The solution appears to lay in celebrations of both individual and national heritage, to foster discussions and understanding of communalities across different cultural groups within the nation.
