Original timber stairwell doors in historic masonry apartment buildings of architectural heritage value can be found in the larger cities of Norway. In Oslo, there are around 4000 such buildings, of ...which many still hold preserved original stairwell doors. The doors often have glass with decorative patterns in the upper parts, and timber panels on the lower part. Old residential buildings are vulnerable to fire due to the building construction and need fire protection upgrades. The stairwell doors are critical elements to prevent fire spread and to keep evacuation routes safe, so their function and condition are important to the level of fire protection in the building. The research work in this paper aims to find retrofit methods for upgrading the fire resistance of these types of doors so they maintain their integrity and insulating properties for up to 30 minutes, at the same time as they maintain their architectural expression. The upgrades must be as little intrusive and destructive as possible. Intermediate scale tests were carried out in a fire resistance test furnace, using different door configurations. The tests lasted between 30 minutes and 42 minutes, with a thermal exposure from the standard time/temperature curve described in EN 1363-1. The results from the tests showed that 40 mm thick laminated wood could withstand up to 30 minutes of fire exposure, thin timber panels could be upgraded using stone wool and robust gypsum boards type R, and that fire-resistant glass could be mounted on the inside of the original glass in different ways. Visual observations indicate that adding smoke seals inside the door leaf are effective for stopping cold and hot smoke. The solutions presented enables the preservation of the original doors' architectural design, their historical values and aesthetic character.
Application of Building Information Modelling methodology, BIM, in the field of architectural heritage in recent years has generated a significant catalogue of experiences classified under the title ...Heritage Building Information Modelling, HBIM. However, these are disparate cases in terms of their scope and purpose without a specified general conceptual framework in which to define each case study. This article proposes a general characterization of HBIM, transferring two BIM concepts originally related to the production and management of new site architecture to the specific context of cultural heritage: BIM Dimensions and Level of Development, LOD, renamed as Level of Knowledge, LOK, for heritage application. According to this conceptual proposal, the HBIM model of the Charterhouse of Jerez has been generated, considering the information required for strategic planning of the main areas of action for heritage management: research, protection, conservation and dissemination.

•HBIM should be understood as a methodology for the comprehensive management of cultural heritage.•The definitions of BIM dimensions are extended to their heritage application in HBIM.•Levels of Knowledge (LOK) are defined in HBIM as LOD heritage application.•An LOK200 model of the Charterhouse of Jerez is presented, suitable for its Master Plan.
In the last decades, the introduction of geomatic technologies in the processes of documentation of built environment has revolutionized the field of morphometric documentation. These procedures have ...undoubtedly helped tangible Cultural Heritage, which in today's society plays an increasingly central role in socio-economic development and the reaffirmation of a country's cultural identity. This research aims to illustrate a management method for Architectural Heritage (AH) using innovative technologies, which allow determining the influence of geographic-environmental conditions on the processes of material and structural degradation of buildings. The case study on which this method was tested is the Facultad de Arte Teatral (FAT) of the Universidad de las Artes in La Habana (Cuba).
Abstract Intangible cultural heritage (ICH) represents living cultural expressions and practices that are part of the heritage of a community, and their preservation and transmission are considered ...highly important. Various methods and tools have been applied so far for the digitization and dissemination of ICH content including a wide range of technologies. Mobile augmented reality is a promising solution along this path that enables the overlap of digital and real-world information in an engaging and efficient manner. Despite the widespread use of AR in cultural heritage, there are not many studies regarding the user experience, the learning outcomes, and the way in which users observe and interact with the virtual content. This paper presents a mobile augmented reality installation that re-enacts the stages of leather tanning process, adopting a novel approach that augments 3D content upon a physical scale model of an old tannery. This approach pursues to transmit the cultural value of traditional craftmanship to visitors of the building and associate its architectural elements to its history and use. A user evaluation was conducted aiming to measure the users’ engagement, learning, and experience using the installation. The encouraging results led to a follow-up study about the impact of the physical scale model on the experience. Two variations of the experience have been studied, one with a physical scale model and one with a digital-only version in a between-subject design. The results of the two studies provide evidence that the proposed approach generated a positive user experience and evident learning gain and was considered easy to use, highlighting its potential to be widely adopted in buildings with architectural value.
Abstract
The ambient environment of architectural heritage is an important factor affecting its conservation. Two adjacent rows of Buddha statues in Grottoes No. 3 (semi-open) of Maijishan Grotto in ...Gansu, China, show apparent differences in the degree of deterioration. This study made a monitoring scheme of grottoes microenvironments such as air temperature, relative humidity, radiation, and surface temperature to explore the cause of the difference. A two-dimensional heat and moisture (HAM) transfer model was established and verified to simulate the temperature and humidity on the surface and inside of the Buddha statues. Then, temperature and water content fluctuation and the risks of thermal stress destruction on the surface and near the surface of the Buddha statues were evaluated. The results show that the radiation difference causes thermal stress and water content differences both in heights and in depths. This impact brought by the direct sunlight may contribute to the different deterioration on the two rows of Buddha statues. The eaves shaded the upper row of the Buddha statues much longer than the lower ones. Less severe fluctuation and differences in temperature and water content occur at the middle and upper points. This study evaluates the degradation of Grottoes No. 3 and has guiding significance for its preservation methods.
With its creation of fissures and fragments, the montage is uniquely positioned to question the representational power of architecture. When related to the field of preservation such a gesture ...conflicts with preservation’s traditional urge to reinstall and complete the architectural fragment into a grander narrative and its underlying leitmotif of authenticity and integrity. From an analysis of Alex Lehnerer’s and Savvas Ciriacidis’s installation Bungalow Germania, the paper explores the possibility of an experimental and critical notion of preservation. A notion emerging from the artistic strategy of montage which frames the fragment as productive rather than reductive. With that, preservation might become a creative just as much as restorative field of practice.
