The article concerns the issue of revitalizing historical buildings by assigning new functions to them. The authors of the writing provide examples of constantly dilapidating edifices in Lublin and their brief historical outlines. Basing on the expert’s report concerning Sobiescy Palace in Lublin, the writers present problems resulting from the technical condition of this as well as other historical buildings. Chances for improving the conditions of such properties by including them in a completely new functional programme are seen by authors. In order to support this thesis, the writers present already implemented revitalization projects in Poland by assigning various new ones, e.g. living and public utility functions to the buildings.

Technical Parameters

Determination of the main characteristics of the topology and technical condition of equipment underoperating conditions is necessary for analyzing and assessing power and electricity losses in intrashoplow-voltage industrial power supply networks. A comparative analysis of the technical characteristicsof automatic circuit breakers VA57-31 (KEAZ), NSX100 TM-D (Schneider Electric), DPX3 160 (Legrand), Tmax XT1 TMD (ABB) has shown that the main technical parameters of the machines are close in their values. At that it has been found out that automatic switches of the BA57-31 series have the lowest value of power losses per pole (7.5 W), whereas the automatic switches of the Tmax XT1 TMD series have the highest value (10 W). Thus, under the operating conditions of the equipment, the lowest value of power and electricity losses is characteristic of low-voltage electrical networks with installed circuit breakers of the BA57-31 series, and the highest value of losses is noted in in-shop systems with installed circuit breakers Tmax XT1 TMD. Using catalog data, the dependences of active power losses in circuit breakers on rated currents have been established; the algorithms have been developed and the obtained dependences have been modeled using approximating functions. The standard deviation of the compiled approximating functions has been calculated. Analytical expressions of the dynamics of power losses per pole have been determined as a function of the rated current. The graphical dependences of the investigated parameters of low-voltage equipment have been presented. The developed models are recommended to be used to increase the reliability of the assessment and refinement of the amount of active power and electricity losses in low-voltage electrical networks of industrial power supply systems, agrotechnical complexes, and enterprises of the public utility sector.

Degradation Of Materials

Continued exposure of human induced vibrations contributes to the degradation of materials and joints, causing the initiation of cracks or the growth of existing ones, such that they may endanger the structure. Loads, which an undamaged structure could safely resist, can be critical if repeated numerous times. This risk is present in various types of historical buildings, and is influenced by changes in vibration magnitude, by the distance from their source, and by the quality of the building’s maintenance. Good maintenance, which includes regular inspections, allows early detection of any emerging damage and its subsequent repair. This article describes the methods and results of the measurement of dynamic response to road traffic and other types of technical seismicity in four historic buildings. The goal of this paper is to present some examples of analysis and evaluation of the effects of such human activity.

Historic buildings and monuments are an important part of our cultural heritage that must be protected and their sustainability ensured, especially when earthquakes occur. In this paper, a technique that uses structural steel frames is proposed as one way of strengthening unreinforced masonry (URM) in historical buildings. The idea underpinning this technique is to reduce the earthquake displacement demand on non-ductile URM walls by attaching steel frames to the building floors from inside. These frames run parallel to the structural system of the building and are fixed at their base to the existing foundation of the building. Furthermore, they are constructed rapidly, do not occupy architectural space, save the building’s historic fabric, and can be easily replaced after an earthquake if some minor damage ensues. The proposed technique was applied to a five-story historical masonry building in Istanbul. The results of seismic performance analysis indicate that even though the building has plan irregularities, the proposed steel frames are able to effectively enhance the building’s seismic performance by reducing inter-story drifts and increasing lateral stiffness and strength.

Abstract The historic Jewish Purification House Bet Tahara was erected in Olsztyn in 1913 on the basis of the debut design of Erich Mendelsohn, a world-famous architect born in Olsztyn. The most valuable element of the building is a self-supporting pyramid vault above a mourning hall. The paper presents the interesting structure of the building, its technical condition before renovation, as well as the scope of work involved in adapting it into a public utility building - MENDELSOHN HOUSE Intercultural Dialogue Centre. The undertaking was executed thanks to the commitment of the building’s leaseholder - “Borussia” Cultural Community Association, which raised money for this goal from public funds.

The article highlights the challenges and proposes solutions for integrating solar PV systems into historic buildings. The essential factors and their constituents (excluding natural and orientation), which limit the integration of solar electrical systems (PV) into historical buildings, are analyzed. It proposes its own view of the degree of value of territories and the most historic buildings and associated legal restrictions. The main properties of photovoltaic cells that influence the choice of solutions for integration into buildings of various categories in territories of different values are determined. The suitability for the integration of the visible parts of solar photovoltaic systems is assessed in terms of their selection and adaptation of their properties in the conditions of the historical environment. The visibility of photovoltaic cells installed on the outer shell of building structures from public spaces is investigated as an aesthetic component of integration, initial conditions, approaches and tools for its analysis. A bunch of value features of territories and buildings with a visual and aesthetic component is proposed as the basis for resolving issues related to determining the level of “criticality of the environment” or “sensitivity of the historical context”. Historical buildings of all categories of value make up a significant part of the construction fund of our state. They are the hallmark of our historic cities. But their normal functioning, and possibly their existence, primarily depends on the preservation of their utilitarian function and adaptation to new energy realities. In order to preserve the architectural heritage for future generations, it is necessary to find such approaches and solutions in the energy modernization of historic buildings that will simultaneously increase comfort, reduce energy bills and minimize environmental impact - to preserve historical and aesthetic values.

Historic buildings are a fundamental part of the tangible cultural heritage of today’s society. However, the energy saving requirements to limit climate change may present limitations with respect to the characteristics of these buildings. In the case of historical buildings from the early 20th century to the present, the bioclimatic design principles applied by architects may have been limited. In some cases, it may be due to project modifications or urban expansion. In this study, these two aspects are analyzed in a case of a historic building located in Seville: The Duclós House by José Luis Sert. This building presents modifications in the roof between the projected and the built one. Likewise, the urban environment is different from the one existing when it was built. The analysis was carried out with energy simulations using weather data from 2000 to 2019. The results show the influence that the modifications of the projected roof and the urban expansion had on the energy performance of the building with respect to the original idea of the building.

Initial Survey

The research on The Initial Survey of Evolution of Adaptive Reuse of Historic Buildings in Thailand is aimed at constructing knowledge for the module named Reuse and Rehabilitation of Historic Buildings. This module is part of the curriculum of Bachelor of Architecture, which studies the role of architecture fabricated within historical buildings. In the era between 1997 and 2012 in Thailand, there was a notable transformation from conservation to contemporary conversion. A review of conservation perspectives indicates a combined multi-disciplinary cooperation between architectural design and conservation. To establish issues regarding the knowledge of conversion, a research question is raised: how do architectural elements play its role through changing of use? Aimed at understanding the complexity among conversion ideologies, issues surrounding architectural elements of historical buildings are rationally explored. Based on significant conversion projects from 1996 to 2012, architectural elements were referenced as to how concepts and objectives were associated.  Qualitative research was conducted through a study of primary sources; survey and classification of representative samples, and secondary documents, records and architectural drawings. The controlling significance of the buildings led to a discussion and an analysis of the architectural designs through new additions and amendments made on the historical fabric. Included in this discussion are the principles of conversion as they relate to the architecture of historic buildings and the ideology of the modification. It is found that understanding a change to architectural elements through an ontological perspective, that of attachment and associational approaches, could clearly reveal the construction programme that felicitates the historical building for which conservation or adaptation is determined. A dialogue on relevant contexts surrounding amendments of architectural elements demonstrated that a strong emphasis towards particular objectives of use could coincidentally harm the historical building’s architectural dimension framework. This leads to the notion that architecture for adaptive reuse should include knowledge of the original construction, a balance among conditions of the existing building, its programming and further habitation.
