While BIM is primarily used for digital modelling and management of modern buildings and infrastructure, hBIM is a specialized methodology for the documentation, analysis, and conservation of cultural heritage. Key aspects such as the use of parametric vs. non-parametric models, the integration of historical sources and scanned data, and the role of both approaches in architecture, restoration, and construction are examined.
Proposal for Enriching the Exhibitions of Two Varna Museums with XR Technological Solutions, 2024

The demonstration objects used are two neighbouring sites in the city of Varna: the archaeological site Small Roman Thermae and the Museum of New History of Varna. Based on the analysis of the location and spatial characteristics of the two sites and their historical contexts, the principles of a multi-layered spatial-temporal scenario for an educational tour of the two museums are developed. The scenario covers three historical periods: Antiquity, the Middle Ages, and the Modern era. In spatial terms, the Antiquity period includes the following sites: the Small Roman Baths in ancient Odessos, a Roman street leading to the baths, a building with a high base and pedestals along the street, and a Roman city house with an impluvium. The Middle Ages are represented by the fortress walls of the citadel and its eastern bastion, while the Modern era is represented by the current building of the Museum of New History of Varna, during the years when it was used as a prison. This period also includes the museum's courtyard and the streets adjacent to it, as they were at that time.

Specifically, the shops approached by us were at the southern facade in the forum of Philippopolis and at the northern facade of the Imperial Roman Thermae of Odessos. From the available artefacts (for example, the stone thresholds) conclusions have been drawn about the unpreserved wooden elements. The Roman culture in the lands of contemporary Bulgaria inherited the Hellenic and the local Thracian culture. The two large-scale archaeological sites are the forum of Philippopolis (the contemporary city of Plovdiv), and the Imperial Roman Thermae in Odessos (the contemporary city of Varna). In spite of the wider cultural frame during developing of the agora of the Hellenistic Philippopolis to a forum in the Roman period, the function of the public space was not changed, incl. the commercial function and the building
structure of the shops, as well the elements on their entrances, partially the thresholds. The difference in the shape of the thresholds at both archaeological sites is not caused by the difference of their architectural schemes. The entrances of the shops in the forum are accessible from the inner space of the portico around the antique square called "area". On the
contrary, the shops in the Imperial Roman Thermae of Odessos are located on the periphery of the building and are accessible from the streets surrounding the building outside. The main difference is caused by the structures of both buildings. The shops of the agora of Philippopolis lay on the ground, and during the following renovations the new elements are placed over the old ones. The thresholds of the shops of the Roman Thermae are placed over openings for ensuring a ventilation of the large structural gallery, supporting the heavy northern wall of the biggest hall of the thermae. Although focused on a limited topic, this publication gives concrete examples of how the function and construction of large ancient buildings affected their smallest architectural details.

Hlebarova on the restoration of the most richly ornamented facade in the city of Varna. The house of the entrepreneur Dimitar Kenkov was built according to a project from 1912 by the great Bulgarian architect Nikola Lazarov. In parallel with the restoration of the facade, the design team conducted research on the interior spaces of the building, needed for the technical passport of the building. The 3D model of the building revealed unusual (hidden or illogical) spaces, as well as the absence of expected ones. The research poses a question related to the lack of such a space, expected according to Nikola Lazarov's original project, but not implemented in place or subsequently walled up. It is unclear whether the reasons were difficulties in carrying out excavation work related to archaeology near the antique fortification wall of Odessos (5th-6th century) or if it is associated with the change in the socio-economic reality in Bulgaria after 1944. Further on-site research would be required to discuss this matter in depth. Upon completion of the restoration work on the facade, access to the interior spaces of the building was restricted for specialists.

TARGET TYPE AND QUALITY: The type and quality of AR targets are important factors for ensuring that they are recognizable in the real space to provide a quality visual response. 2.TARGET SCALING: The scale of targets must be appropriate for the purpose of AR. The paper provides concrete examples from the author's work on demonstrating architectural projects with AR.

The team vectorized the old paper plans from 1912, did aerial and terrestrial photos and movies, completed the data acquisition from 2D images to a 3D model, testing 3 types of software for photogrammetry, and finalized the building information model (BIM). The BIM is a base for creating the building energy model (BEM) and applications for virtual reality (VR) and augmented reality (AR) of the same building. The work is included as a virtual demonstration site in the H2020 project BIM-SPEED (Harmonized Building Information Speedway for Energy-Efficient Renovation).

The building is a representative of the architectural style of the Modernism. Nowadays it is in a worse condition than ever. The research team of Dr. N.Stamatova was involved in the project of D.Hristova, architect, specialist in the topic of the industrial archaeology. The digitization works, described in this publication were processed in the summer of 2019. They were done with the participation of 6 interns on the programme “Erasmus+” under the mentorship of Dr.N.Stamatova as follows: 2 engineers on-site and also 2 architects and 2 graphic/video designers in the studio of Architectural Spies EOOD. The digitizing of the building as soon as it is possible was very important, because of penetrating rainwater through the missing parts of the roof, the diffusion of vegetation on the perimeter of the foundations, and vandalism. The digitization works used the remote survey materials collected by a professional drone and 4 photo-devises used terestially from human eyes horizon and also from 2 upper levels with two different telescopic sticks (0.9 m and 3.8 m). The on-site survey was performed in the interval 1 p.m. – 2 p.m. (astronomical 12 a.m.-1p.m.), approximately when the sun was at its zenith. The data processing used the software product for photogrammetry Zephyr. A movie about the on-site works is included in the CD attached to the printed issue.

season of 2019 of the efforts of R&D SME Architectural Spies for
creating a precise three-dimensional base for further developing of the
digital reconstruction of the Imperial Roman Thermae of the ancient
Odessos. The initial 3D model of the reconstruction was created by
the team of Dr. N. Stamatova with the scientific support of Prof. Dr.
S.Boyadzhiev between 2006 and 2013.
The first attempts of the team to create a 3D model of the above
archaeological site, based on the method of photogrammetry, were
done in 2013-2014 by the software 123D Catch and ReMake
(Memento), the predecessors of the current for 2019 software ReCap.

The work in the summer of 2019 was done with the
photogrammetric software Zephyr. The next results will be presented
as a publication Part II. The team considers that the achieved precision
in digitization of the existing ruins in 2019 is sufficient for continuing
the work on the assembling of the prepared 3D models. The final 3D

A piece of peace in sWARajevo: Locally and globally interesting stories for virtual museums
2013 Digital Heritage International Congress (DigitalHeritage), 2013

The local interestingness is understood in a Koestlerian way (AH, AHA, HAHA bisociation effects). Global interestingness is achieved by discovering, within the given unique material, options for relating unrelated contexts, internal poetry and/or change of the narration mode. The craft of storytelling resulted in five short movies, completed during the South-East European Virtual Heritage School: Digital Storytelling for Virtual Museums. These intereStories“ are intentionally aimed at overcoming multiple limitations of backtelling, frequent in virtual museums. The five themes include Bosnian blues Sevdah, fate of Sephardic Jews, existing and nonexisting urban area, and traditional Bosnian coffee. The stories were coauthored by 15 beginners storytellers in groups (24 authors) in 5 days alongside with the 12 lectures on theory and narrative case studies from V-must network good practice. Besides the brainstormings, speed-up focused brainwritting feedback was provided twice: once for preexistent stories, second for betaversions. The final creations were produced in Adobe Premiere Pro and published at YouTube.
