This paper investigates a novel controlled-temperature double-skin façade (DSF) building element. A three-dimensional time-dependent numerical model was developed for six different geometries for the investigation of thermal performance under different orientations (azimuth 0°, 90°, 180° and 270°). The boundary conditions of the numerical model were determined with the PVGIS tool and adjusted with the sol-air temperature equation. The results of the numerical simulation were validated with the use of measurements from an experimental test cell. The numerical results indicated an improved thermal performance when temperature-controlled air and flow were supplied through the building envelope with annual total energy savings in kWh/m² of 1.99, 1.38, 2.13 and 2.06 for azimuth 0°, 90°, 180° and 270°, respectively. In regard to the total energy savings in %, the maximum benefit was considered to be in the winter season, with values of 65, 29, 80 and 28 for azimuth 0°, 90°, 180° and 270°, respectively. The experimental measurements revealed the test cell’s ability to maintain a relatively constant internal surface temperature and to not be significantly affected by the orientation and diverse ambient conditions.

The integration of advanced terrestrial laser scanning (TLS) techniques into building information modelling (BIM) workflows has significantly enhanced the digitization and preservation of cultural heritage sites. In this context, crowdsourcing can operate as a complementary upstream mechanism for enriching heritage inventories, supporting participatory mapping, collecting preliminary condition observations, and prioritizing assets for subsequent expert-led TLS acquisition, HBIM modelling, and structural assessment. This paper explores the application of TLS within BIM for the structural assessment and the long-term monitoring of historic structures. The reviewed studies show how high-resolution TLS data can support the development and updating of geometry-informed structural models, enabling detailed structural assessment and effective management strategies. The reviewed case studies demonstrate the practical benefits of integrating TLS with BIM, such as improved accuracy in structural assessments, enhanced data processing capabilities, and the creation of comprehensive digital twins. These advancements facilitate better-informed decision-making and targeted preventive measures, contributing to the resilience and preservation of cultural heritage assets. The results underscore the contribution of TLS–BIM/HBIM workflows to condition-informed documentation, structural assessment, conservation planning, and long-term heritage management. This research was supported by the ERA4CH project, which aims to protect European cities’ cultural heritage from earthquake risks through innovative monitoring and management tools.
