Since the European Year of Cultural Heritage, adaptive reuse is considered a strategy for intervention on historical buildings and territories to preserve and enhance artifacts, cities, and communities. Adaptive reuse can also generate social and economic benefits. This work looks at adaptive reuse in the context of industrial heritage, which represents an excellent test benchmark because of its intrinsic architectural characteristics and its localization in the city suburbs. The paper puts forward a methodological approach, verified through the application to a case study, which analyzes both the local context and the building. This study concludes using the data obtained to define an adaptive reuse project with positive repercussions for the community, the environment, and the local economy.

Purpose – The purpose of this paper is to develop and discuss a methodological approach for energy assessment and retrofitting of envelope systems in Mediterranean historical buildings, in order to ensure the desirable balance between improvement requirements and preservation principles. Design/methodology/approach – The methodology is based on the assessment of historical districts at the site, building and component scales, the development of energy models of building-types that are highly representative, in terms of materials, construction techniques, typologies and performances, the identification of intervention priorities and the validation of compatible retrofitting solutions. Findings – The methodology, applied to a representative Adriatic sea town in South Italy, shows the potentialities of innovative materials and technologies (aerogel, PCMs, etc.) as tools to achieve the improvement of the energy performances and the preservation of the original characters. Nevertheless, it shows how the preliminary qualification of the environmental, architectural, constructional and technological characteristics is paramount to support the identification of the current behavior of the building system and the transformation boundaries from the historical values. Originality/value – The paper proves how assessment and intervention methods and tools, besides effective, compatible, low invasive and durable, should be geocluster oriented and performance based, thus with general reliability for the whole local context and suitable flexibility to be tailored to different specific situations, toward the definition of retrofitting micro-scale measures and macro-scale strategies that are replicable and scalable.

La presente investigación se dirige a realizar una identificación detallada de las fuerzas externas (factores de deterioro naturales y humanos) e internas (materiales constructivos) que afectan a los aparejos en los edificios históricos. Desde este punto de vista, la estructura de un edificio puede definirse como una combinación estable de elementos que se conciben como una unidad, para soportar y transmitir al terreno las cargas correspondientes de forma segura y sin exceder los límites de resistencia de cada uno de estos elementos.En concordancia con este enfoque, se estudiarán las relaciones entre ambos tipos de fuerzas, tomando en cuenta que las fuerzas internas poseen la misión de contrarrestar las externas para conservar el equilibrio estructural de un edificio. La adecuada comprensión de estas relaciones permitirá elaborar una aproximación metodológica para intervenir sobre los aparejos en edificios históricos, desde el respeto a su autenticidad como elementos estructurales y formales del patrimonio arquitectónico. En este sentido, el respeto a la autenticidad solamente puede alcanzarse investigando las técnicas y los materiales constructivos que se utilizaron en la época a la que pertenece un edificio histórico determinado, lo cual facilita que el proceso de restauración y reestructuración del patrimonio arquitectónico se lleve a cabo preservando sus valores históricos y artísticos.Dado que la estructura distingue a la arquitectura del resto de las artes, toda intervención sobre el patrimonio arquitectónico debe partir de la idea de que los elementos estructurales desempeñan una función práctica, contribuyendo de manera decisiva a la conservación de un edificio a través del tiempo, pero también se les puede atribuir una función estética, expresando con ellos los valores artísticos de la época a la que pertenecen. Esta idea se ha reflejado en la historia de la arquitectura desde la Grecia clásica, de modo que los elementos estructurales de cada época se han convertido en símbolos de su arquitectura. En el desarrollo de esta actividad, siempre se puede resolver un problema de varias formas igualmente válidas, pues la atención y el esfuerzo que se dedican a los detalles formales, más allá de las exigencias del cálculo estructural, rebasan el ámbito meramente técnico y aportan valores artísticos de manera deliberada o fortuita.AbstractThis research is aimed to carry out a detailed identification of the external forces (natural and human factors of deterioration) and internal (building materials) which affect the bonding of walls in historical buildings. From this point of view, the structure of a building can be defined as a stable combination of elements which are conceived as a whole, in order to bear and transmit the pertinent loads to the ground in a safe manner and without exceeding the resistance limits of each one of these elements.According to this approach, relations between both types of forces will be studied, considering that internal forces have the purpose of counteracting the external ones in order to preserve the structural balance of a building. The appropriate understanding of these relations will allow to make up a methodological approach to operate on the bonding of walls in historical buildings, from the respect to its authenticity as structural and formal elements of architectural heritage. In this sense, respect to authenticity can only be achieved doing research on the building techniques and materials which were used in the time which a specific historical building belongs to, which facilitates to carry out the restoration and restructuration process of architectural heritage preserving its historical and artistic values.Given that structure differentiates architecture from the other arts, every operation on architectural heritage must start from the idea that structural elements accomplish a practical function, making a crucial contribution to preserve a building through ages, but they can also have an aesthetic function, expressing the artistic values of the time which they belong to. This idea has been reflected in history of architecture from the classical Greece, in a way that the structural elements of each time have become symbols of its architecture. In the development of this task, a problem can always be solved in different manners which are equally acceptable, because the attention and the effort which are invested in formal problems, beyond the requirements of structure calculation, overtake the sphere of mere technique and provide artistic values in an intentional or accidental way.

Medan is the third-largest city in Indonesia, and so do their heritage. The historic building in Medan City is a valuable asset. These buildings have infinite value and essential to people that ever lived there. Throughout more than five generations, these shophouses are stood still until today and waiting to be eaten by age. Therefore, this area should be conserved. Buildings that lived in Pasar Hindu slowly become extinct because of ignorance from people. Thus, an act of revitalization to this place should be done to conserve the story that ever recorded in this place, so that our next generations can learn and appreciate our history. This project is about how architecture can act as preservation in the historical area throughout the environmental design by the methodological approach. Heritage is a beautiful theme that keeps the scent and the scars of old stories that ever crouched at the shophouse. Compared to other countries that have successfully rejuvenate their historic buildings, their achievements developed much more than building façade but also increased the economic income of the community. These historical buildings had finally become a valuable asset for the owner, precious gems to the city, and pride to the nations.

Abstract This study, presented in a pair of articles, defines a comprehensive methodological approach to the reconstruction of a traditional masonry-timber mansion building constructed in the 1880s of the Turkish house typology on Istanbul’s historical peninsula area that was intentionally demolished in 1948. A historical process research was carried out in the first stage of the study, after which ground penetration radar measurements and an archeological excavation were carried out to determine any possible remains or ruins of the structure, and the original architectural features of the demolished building were ascertained from the obtained data. The proposed stages in the current paper can be considered a comprehensive approach to the determination of the authentic properties of demolished or destroyed buildings in historical areas, given that the methodology allows for the integration of construction features obtained separately and independently through different activities, such as excavations, georadar measurements and historical surveys. The result is a versatile approach to the complete and realistic reconstruction of historical buildings.

The energy analysis of electrons scattered by a specimen in a scanning transmission electron microscope can improve contrast as well as aid in chemical identification. In so far as energy analysis is useful, one would like to be able to design a spectrometer which is tailored to his particular needs. In our own case, we require a spectrometer which will accept a parallel incident beam and which will focus the electrons in both the median and perpendicular planes. In addition, since we intend to follow the spectrometer by a detector array rather than a single energy selecting slit, we need as great a dispersion as possible. Therefore, we would like to follow our spectrometer by a magnifying lens. Consequently, the line along which electrons of varying energy are dispersed must be normal to the direction of the central ray at the spectrometer exit.
