From Site Survey to HBIM Model for the Documentation of Historic Buildings: the Case Study of Hexinwu Village in China
Full text linkArchitectural heritage surveying plays a fundamental role in the preservation of historic buildings for scientific research, education and tourism. The use of Unmanned Aerial Vehicles and Terrestrial Laser Scanning techniques are essential for architectural heritage surveying and mapping. In recent years, the combination of Building Information Modelling (BIM) with heritage studies has been presented as Historic BIM (HBIM) which, integrated with UVA and TLS, is a technique that is able to deal more efficiently with the management and protection of historic buildings. This paper focuses on the integration of UVA images and point clouds from laser scanning to build a 3D architectural model for the documentation of Chinese historic buildings. In particular, the method, tested in the case study of the traditional village, Hexinwu, China, can contribute further to the analysis, evaluation and heritage planning of this remarkable architectural structure, thus increasing its historical significance for the future.Il rilievo del patrimonio architettonico è fondamentale nella conservazione degli edifici storici per la ricerca scientifica, l'istruzione e il turismo. L'uso dei veicoli aerei senza pilota e le tecniche di scansione laser terrestre sono essenziali per il rilevamento e la mappatura del patrimonio architettonico. Negli ultimi anni l'abbinamento del Building Information Modeling (BIM) con gli studi sul patrimonio è stato presentato come Historic BIM (HBIM) che, integrato con UVA e TLS, permette di affrontare in modo più efficiente la gestione e la tutela edifici. Questo documento tratta l'integrazione di immagini UVA con l’insieme punti scansionati con laser per costruire un modello architettonico 3D per la documentazione di edifici storici cinesi. In particolare, il metodo testato nel caso di studio del villaggio tradizionale, Hexinwu, Cina, può contribuire ulteriormente all'analisi, valutazione e pianificazione del patrimonio di questa straordinaria struttura architettonica, aumentando così la sua importanza storica per il futuro
Laser Scanning Data in Revitalization Projects for Historical Building
No full textArchitectural heritage carries rich historical and cultural connotations and is the witness and inheritance of history. The country has always advocated the scientific and effective protection of architectural heritage to inherit history and culture. However, with the rapid development of science and technology, traditional protection methods can no longer meet society’s needs for the protection of architectural heritage. Public demand for architectural functions is increasing
Protection and renewal design of architecture heritage with 3D laser scanning data: taking La Villa Viti in Mazzolla
No full textThis book collects the Proceedings of the fourth edition of the conference “CLIMATE CHANGE AND CULTURAL HERITAGE. IV International Forum on Architecture and Urbanism”, held on 22 and 23 June 2023, in the New Rector’s Palace in Caserta. After the editions in Tirana (Albania) in 2017, Pescara (Italy) in 2018 and Tirana (Albania) in 2019, the IFAU Conference is coming to the University of Campania “Luigi Vanvitelli” in the June 2023. We received 165 papers from Albania, Algeria, Argentina, Brazil, China, France, Germany, Italy, Iran, Kosovo, North Macedonia, Nigeria, Portugal, Czech Republic, Spain, USA. The authors and co-authors who participated in the call are 329 from prestigious Universities, Departments and Research Centres in the world. The IFAU23 Conference entitled Climate Change and Cultural Heritage promotes studies and research on the past, present and future of architecture, the city, and the landscape. Climate Change that affl icts our Planet is a worldwide problem for humanity and affects the practices of knowledge, management and protection of cultural heritage. Cultural Heritage includes the interdisciplinary themes of possible questions related, in one, to the Heritage as a set of multiple categories, from artifact to natural. The IFAU23 Conference proposes a large discussion on cultural heritage as a “place of Life” for all living beings on the Planet as well as on best practices related to heritage as a “place of experience” for the knowledge and protection of the built and natural environment, material and immaterial, tangible and intangible. The contributions will be included in the three topics to follow (architecture; city and landscape; living environments) to activate an interdisciplinary discussion on the topics and criticalities of the current relationship between Climate Change and Cultural Heritage in the opinion that scientific knowledge must always accompany the progressive impact on the life of communities
Three-Dimensional Documentation and Reconversion of Architectural Heritage by UAV and HBIM: A Study of Santo Stefano Church in Italy
Full text linkHistoric buildings hold significant cultural value and their repair and protection require diverse approaches. With the advent of 3D digitalization, drones have gained significance in heritage studies. This research focuses on applying digital methods for restoring architectural heritage. It utilizes non-contact measurement technology, specifically unmanned aerial vehicles (UAVs), for data collection, creating 3D point cloud models using heritage building information modeling (HBIM), and employing virtual reality (VR) for architectural heritage restoration. Employing the “close + surround” oblique photography technique combined with image matching, computer vision, and other technologies, a detailed and comprehensive 3D model of the real scene can be constructed. It provides crucial data support for subsequent protection research and transformation efforts. Using the case of the Santo Stefano Church in Volterra, Italy, an idealized reconstructed 3D model database was established after data collection to preserve essential resources such as the original spatial data and relationships of architectural sites. Through the analysis of relevant historical data and the implementation of VR, the idealized and original appearance of the case was authentically restored. As a result, in the virtual simulation space, the building’s style was realistically displayed with an immersive experience. This approach not only safeguards cultural heritage but also enhances the city’s image and promotes tourism resources, catering to the diverse needs of tourists
Assessment of the Exterior Quality of Traditional Residences: A Genetic Algorithm–Backpropagation Approach
Full text linkThe visual aesthetics of villages are remarkably affected by the exterior quality of traditional residences, influencing the impression and assessment of local culture. A proper scientific assessment of exterior quality can protect traditional cultures and improve the development of villages. This research was conducted in a village consisting of 115 residences (Mengjinglai village, which is on the border between China and Myanmar). The backpropagation (BP) neural network model with genetic algorithm (GA) was applied to evaluate the quality of the dwellings. All the evaluation values of the dwellings were defined by scores. Meanwhile, the score of each residence was affected by three main factors: architectural spatial elements, architectural construction elements, and historical and cultural elements. The results show that the village’s dwellings are well preserved and clearly express the traditional Dai style. Moreover, the GA–BP approach is more suitable than the traditional BP method for the assessment of the exterior quality. The quantitative machine learning model would be useful for other aspects of the assessment of similar villages in the future
Architectural Cultural Heritage Conservation: Fire Risk Assessment of Ancient Vernacular Residences Based on FAHP and EWM
Full text linkThe architectural relics of ancient vernacular residences and villages with brick–timber structures are at great risk of fire; if one occurs, they cannot be recovered. To protect this cultural heritage, this study takes a southern Guangdong He Xinwu building complex as a case study. It focuses on four indicator systems: human factors, facility factors, environmental factors, and social management factors, and 20 sub-indicators to establish an assessment system for fire risk in vernacular residences. Combining triangular fuzzy hierarchical analysis and the entropy weight method to determine weight values reduces evaluation subjectivity, allowing for both qualitative and quantitative measurements to derive the safety level and determine key fire risk factors. The results showed that human misconduct and social management of fire had the greatest impact on fire risk (29% and 25.8%, respectively). The most important secondary indicators were the ability to fight fires early on, the fire resistance level of building materials, fire rescue capability, fire load, and electricity use by villagers. Moreover, comparing differences in protection between ancient houses and high-rise buildings provided targeted policy recommendations that offer a new perspective for protecting architectural heritage from fires

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
