The continuous increase in cultural tourism, together with the deficient planning of public use, increases the risk of heritage resource degradation. Currently, there are collaborative methodologies enabling all the agents involved in the conservation of a heritage site to work in a coordinated way (HBIM), such as in the management of public use. However, in this study, through a review of the scientific literature, the lack of a method and tool that allows sustainable conservation management and the planning of cultural tourism of heritage assets in a specific geographical environment is demonstrated. The objective of this research is thus to explore and identify the possibilities of interoperability between HBIM and GIS for the development of a protocol aimed at synchronizing the information concerning heritage architecture across the management and cultural tourism planning and preventive conservation. This protocol was implemented for three monumental buildings in the historic centre of the city of Valencia (Spain). This novel protocol provides a new technological system that fosters the cultural development and preservation and conservation of heritage assets through a single tool integrating HBIM and GIS.

This article presents a bibliometric analysis conducted on the implementation of sensor-extracted data in the context of Historical Building Information Modeling (HBIM) with a focus on the conservation of heritage buildings. The study utilized recognized databases, namely, Web of Science (WoS) and Scopus. A bibliometric analysis methodology was applied, employing the VOSviewer 1.6.19 software. The results obtained provide a robust overview of the current state and trends in HBIM and sensor research and enabled the identification of emerging trends in the field of preventive conservation. Three promising trends were identified, establishing connections between this field and 4D spatial data management, energy performance, and artificial intelligence. Additionally, relations with climate change were also detected. These trends underscore a significant convergence of technologies and methodologies in the realm of heritage building conservation. The conclusions serve as a valuable contribution to guiding future research in the field of built heritage conservation.

This study explores the potential of Heritage Building Information Modeling (HBIM) and Geographic Information Systems (GIS) for assessing tourist visitation and managing public use of heritage buildings. By integrating these tools, the research aims to improve preventive maintenance and conservation management in culturally significant buildings and urban outdoor spaces. The findings demonstrate the value of HBIM and GIS in handling spatial information and facilitating reliable decision-making for tourist itinerary design and visitor flow management. By examining three buildings of the highest degree of protection as assets of cultural interest, the information obtained can be extrapolated to a municipal management network that encompasses numerous urban models. The integration of databases enables the combination of data at different scales, from the building level to the territorial level, involving all relevant stakeholders from various disciplines. The results highlight the importance of using digital tools in the context of heritage architecture and public use management, promoting more sustainable practices in the preservation and conservation of our cultural heritage.

One of the greatest challenges in heritage management is to find a balance between the demands of visitor access and heritage conservation. The income generated prevents decay and benefits the conservation of buildings. At the same time, cultural tourism can accelerate the deterioration of buildings from increased use and an increase in agents harmful to conservation. This unique research analyses the influence of building use at San Juan del Hospital, the oldest church in the city of Valencia. Its architectural characteristics and the climate of the city mean that visits to the building put the conservation of its heritage assets at risk. Monitoring data from the summer months were put into a digital twin generated from a heritage building information model (HBIM), and the modelling of visitor numbers and the impact on indoor environmental quality was conducted. Monitoring and simulations confirmed that visitor numbers need to be reduced or mechanical conditioning systems need to be installed to prevent damage to the heritage artefacts within the building. This research provides building managers with information to make informed decisions about the preventive maintenance of heritage buildings. This research also demonstrates for the first time the value of using monitoring and a digital twin for conservation management.

Accurate documentation of the geometry of historical buildings presents a considerable challenge, especially when dealing with complex structures like the Metropolitan Cathedral of Valencia. Advanced technologies such as 3D laser scanning has enabled detailed spatial data capture. Still, efficient handling of this data remains challenging due to the volume and complexity of the information. This study explores the application of clustering techniques employing Machine Learning-based algorithms, such as DBSCAN and K-means, to automate the process of point cloud analysis and modelling, focusing on identifying and extracting floor plans. The proposed methodology includes data geo-referencing, culling points to reduce file size, and automated floor plan extraction through filtering and segmentation. This approach aims to streamline the documentation and modelling of historical buildings and enhance the accuracy of historical architectural surveys, significantly contributing to the preservation of cultural heritage by providing a more efficient and accurate method of data analysis.

La puerta de la muralla árabe de Valencia denominada de en Esplugues es el prin­cipal referente utilizado para la delimitación de los dos últimos recintos judaicos que tuvo la ciudad. Esta puerta se ha localizado en un lugar diferente al tradicionalmente establecido demostrando que las juderías valencianas tuvieron menor superficie de la que hasta ahora se ha considerado. Asimismo se dispone sobre un plano parcelario actual el perímetro de la tercera judería, localizando los hitos que se mencionan para su deli­mitación en el privilegio de Juan I de 1393 atendiendo a datos extraídos de otros docu­mentos que apoyan su nueva ubicación.
