Dataset of Virtual and Real-Life Visual Experiences Inside a Museum: Survey on Visual Perception With Objective and Subjective Measures
(Elsevier, 2023) Salvadori, Giacomo; Tambellini, Giuseppe; Çevik, Aslıhan; Kazanasmaz, Zehra Tuğçe; Leccese, Francesco
Occupants’ perception of a space depends on their experience [1–3]. Four kinds of visiting experiences were carried out inside the Natural History Museum of the University of Pisa [4]. The museum is housed, together with the National Museum of the Charterhouse [5], inside the Monumental Charterhouse of Calci, near Pisa. Four of the permanent exhibition halls of the Museum were selected for the survey: Historical Gallery, Mammal's Hall, Ungulates’ Gallery and Cetaceans’ Gallery. A total of 117 participants were divided into four groups depending on their visiting experience: real-life, or virtual based respectively on videos, photos or computer-generated photorealistic images (renders). Experiences are compared. The comparison comprehends objective data (measured illuminance levels) and subjective data (questionnaire outcomes on the perception of the space). The illuminance levels were measured using a photoradiometer: datalogger Delta Ohm HD2102.2 equipped with LP 471 PHOT probe. The probe was placed 1.20 m above floor level, and it was set to measure vertical illuminance at 10 seconds intervals. To evaluate participants’ perception of the space questionnaires were used. The presented data refer to the article: “Perception of light in museum environments: comparison between real-life and virtual visual experiences” [1]. This kind of data provides a base to assess if virtual kinds of experience can be implemented in museum environments as an alternative to the real-life experience, and to understand if such an implementation is detrimental or not in terms of participants’ perception of the space. Virtual experiences can be particularly useful for spreading culture, making it accessible even in presence of moving restrictions for people, such as those in force today due to the SARS-CoV-2 emergency.

Experimental data showing the thermal behavior of a flat roof with phase change material
(Elsevier, 2015) Tokuç, Ayça; Başaran, Tahsin; Yesügey, Sadık Cengiz
The selection and configuration of building materials for optimal energy efficiency in a building require some assumptions and models for the thermal behavior of the utilized materials. Although the models for many materials can be considered acceptable for simulation and calculation purposes, the work for modeling the real time behavior of phase change materials is still under development. The data given in this article shows the thermal behavior of a flat roof element with a phase change material (PCM) layer. The temperature and energy given to and taken from the building element are reported. In addition the solid-liquid behavior of the PCM is tracked through images. The resulting thermal behavior of the phase change material is discussed and simulated in [1] A. Tokuç, T. Başaran, S.C. Yesügey, An experimental and numerical investigation on the use of phase change materials in building elements: the case of a flat roof in Istanbul, Build. Energy, vol. 102, 2015, pp. 91-104.

Application of Climate-Based Daylight Simulation To Assess Lighting Conditions of Space and Artworks in Historical Buildings: the Case Study of Cetacean Gallery of the Monumental Charterhouse of Calci
(Elsevier, 2020) Leccese, Francesco; Salvadori, , Giacomo; Tambellini, Giuseppe; Kazanasmaz, Zehra Tuğçe
Exhibits are often displayed in spaces originally not designed to be museums. Thus, is common for those spaces to fail adequate lighting display conditions, both in terms of the artworks’ conservation and visitors’ comfort. In order to objectively assess if an exhibition meets the required standards it is necessary to establish a proper evaluation method. This work proposes a novel procedure relying on climate-based data and dynamic daylight metrics. The procedure, that considers both artworks’ and visitors’ needs, can provide museum curators with scientific, repeatable data. These data can help them screen out potential interventions until the most adequate is found. The main advantages of the new approach are that, if properly validated, the simulations can substitute annual measurement campaigns (thus leading to time and costs savings), and the results are very reliable (thanks to the use of climatic data specific for the site in exam) and that the effectiveness of potential interventions can be predicted simulating as many sceneries as needed. The novel procedure can be applied to assess the exhibits’ display conditions in historic building whenever daylight is the main light source. The validity of the procedure is demonstrated through its application on a case study: the Cetacean Gallery of the Monumental Charterhouse of Calci, near Pisa. The outcome of the assessment demonstrated that the Gallery is over-lit and the exhibits are being damaged, for this reason four potential interventions have been analysed and compared. The accuracy of the simulations was validated through a comparison with on-site measurements. © 2020 Elsevier Masson SAS
