Dendroarchaeology is often discussed with reference to prehistoric contexts; however, it is equally relevant in historical contexts. Dendroarchaeological analysis independently dates the modem reconstruction of prehistoric Kinishba Pueblo with higher resolution than known documentary sources provide and illuminates reroofing practices. Kinishba is a large Mountain Mogollon pueblo on the Fort Apache Indian Reservation in east-central Arizona. Historically, the reconstructed Kinishba is attributed to the 1930s work of Byron Cummings. Nineteen dates from structural beams in nine rooms of the pueblo form a tight cluster with a strong terminal peak at 1950. This peak combined with beam and architectural attributes provides evidence for an undocumented, extensive reroofing episode. Thus, the target event was not the building of reconstructed rooms as originally expected, but replacement of the original reconstructed roofs. This study illustrates two important dendroarchaeological points. First, preconceived ideas, even if based on sound research, should not influence sample dating, which should be free of bias. Second, this study illustrates the importance of tree-ring dates in archaeology and the potential conflict between other types of data and tree-ring dates.

This study assesses the growing field of green building for its potential impact on the field of historic preservation. It is designed to provide a starting point for building owners and professionals in the industry seeking to gain LEED-EB certification on a historic structure. The potential impact of each LEED-EB credit to adversely affect historic fabric is evaluated for preservation, rehabilitation and reconstruction projects as defined by the Secretary of the Interior. Strategies for gaining certification for historic structures are discussed. Recommendations for further growth between the fields of historic preservation and green building are given. Early projects that combine historic preservation and green building are briefly discussed. / Department of Architecture

Tree-ring series of oak, from both living trees (Quercus petraea and Q. robur) and historic timbers in southeastern Slovenia were assembled into a 548-year regional chronology spanning the period A.D. 1456–2003. It is currently the longest and the most replicated oak chronology in this part of Europe located at the transition between Mediterranean, Alpine and continental climatic influence. The chronology correlated significantly with regional and local chronologies up to 700 km away in Austria, Hungary, Serbia, Czech Republic and southern Germany. It also showed good ‘‘heteroconnection’’, i.e. agreement with chronologies of beech (Fagus sylvatica), ash (Fraxinus excelsior) and silver fir (Abies alba) in Slovenia. A preliminary dendroclimatic analysis shows that precipitation and temperature in June accounted for a high amount of variance (r250.51) in the tree-ring widths. The chronology thus contains considerable potential as a climate archive. We also present its use as a tool for the dating of wooden objects of the cultural heritage. Moreover, the chronology can be a point of reference for building tree-ring chronologies in neighboring regions.

Esta tese se refere ao estudo do edifício do Museu Paulista, identificando as características da técnica construtiva tradicional de alvenarias, quanto ao sistema estrutural e os materiais empregados. Descreve as circunstâncias históricas, a evolução do emprego da taipa para o emprego do tijolo, e a inserção do edifício do Museu Paulista na cidade de São Paulo em meados do século XIX. Analisa as características que diferenciam um edifício histórico de um edifício moderno relativo às soluções estruturais e a natureza dos materiais. O sistema estrutural tem como elementos principais paredes e pés-direitos, arcos e abóbadas, colunas e pilastras, pisos de assoalho e abobadilha, e fundações. Os materiais são analisados quanto à presença de umidade constante, devido à inexistência de impermeabilização das fundações, a presença de sais solúveis, a porosidade dos materiais, a presença de microrganismos, e a relação com o tipo de tinta utilizada na pintura. Através do levantamento do histórico das intervenções, verifica-se que entre elas há aquelas que causaram danos ao edifício, pelo fato de não considerar as características específicas que o definem. Através de ensaios exploratórios, se reconstitui os traços das argamassas e identificam processos de danos / This thesis refers to the study of the building of Museu Paulista and identifies the characteristics of the traditional masonries constructions techniques that involves the structural systems and the materials used. It describes the historical circumstances and of the evolution of taipa to brick and the inclusion of the building of Museu Paulista in the city of São Paulo in the middle of XIX th Century. It also analyses the characteristics that differs one history and modern build structural solutions and the nature of materials. The main structural systems are constituted by walls, right feet, arch and vault, pilaster and colums, wooden floor, abobadilha, and foundation. The materials are analysed in the several aspects such as the presence of constant humidity, that occurs when there isnt the impermeabilization of the foundations; presence of solubles salts; the porosity of materials; the presence of microorganism and the type of paint used in the painting. Through the history intervations it is verified that amount them there are some generated caused damage to the building due the fact that the specified characteristics were not taken account of. Through the exploratories essays it is reconstructed the composition of the mortars and the identification of the damages process.

The key issue addressed by this dissertation is that a number of heritage buildings undergoing the adaptive reuse are having building components such as timber structure, timber staircase which cannot meet the current fire safety regulation. Given this, it is imperative to begin researching the reasons why the timber component in heritage buildings cannot comply with the current statutory fire resistance requirement and find out the methods in preserving the timber component. The dissertation will focus on timber floor which is a highly important component in meeting the fire safety requirement as it provides the compartment separation to inhabit the rapid spread of fire and smoke in a building and as the same time it is usually a character defining element having heritage value. The dissertation will try to find out the different methods of conserving the timber floor of the heritage building under adaptive reuse with examples. The different methods will be evaluated based on the fire performance, statutory acceptance and conservation principles and the appropriate method will be matched to the adaptive reuse heritage buildings in Hong Kong. / published_or_final_version / Conservation / Master / Master of Science in Conservation

This dissertation seeks to investigate the grading system and its effect on the private property development right of historic buildings in Hong Kong. Unlike the statutory nature of declaring a monument, the grading system is an administrative and internal measure that is mainly referred to the Antiquities and Monuments Office and Antiquities Advisory Board, and has no statutory significance. It could be understood that statutory measures, like declaring a monument, has an effect on development rights in the way that development parameters imposed under statutes have an effect on a given site; however despite the administrative nature of the grading system, there is a very strong perception among property owners and development that historical building gradings also have an effect on development rights. This dissertation will introduce the notion of and conflict between private property development rights and heritage conservation. Case studies from the local Hong Kong context will be used to illustrate the frustrations property owners face when trying to determine the future of their graded historic buildings. The dissertation will conclude using uses overseas case studies to provide some pointers on the way forward for the local heritage conservation system. / published_or_final_version / Conservation / Master / Master of Science in Conservation

This research serves as a reference not only for persons or organizations intending to propose adaptive re-use of or A&A works to a historical building of Cattle Depot but also for architects, engineers, surveyors, heritage conservationists and designers who are engaged for this type of project as a Youth Hostel. The hypothesis of this dissertation is that there is a high demand for urban youth hostels in Hong Kong and such youth hostels are in critical short supply. This leads to the scope of my dissertation, which is to explore the technical feasibility to adapt a heritage building as an urban youth hostel. After conducting comprehensive desk study and site inspection to the Cattle Depot, the methodology of the study will be based on the various statutory submission stages of adapting a building for a new use. To be more precise, this study will examine the procedures of adaptive reuse in terms of (1) what to do and (2) how and where to get it done in the following three main stages in Planning, Building and Licensing. Last but not least, there would be a way forward of historical building sustainability, to change the more appropriate adaptive reuse as a Cattle Depot Youth Hostel would be more possible as a solution to meet the needs of community and benefit to that district development. More importantly, a number of tangible heritages of the Cattle Depot could make use of these available resources to tell of its story history to the community. / published_or_final_version / Conservation / Master / Master of Science in Conservation
