Data Paper 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, FrancescoOccupants’ 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.Article Citation - WoS: 5Citation - Scopus: 6Laptop Displays Performance: Compliance Assessment With Visual Ergonomics Requirements(Elsevier, 2021) Leccese, Francesco; Rocca, Michele; Salvadori, Giacomo; Öner, Merve; Burattini, Chiara; Bisegna, FabioThe use of display devices such as smartphones, tablets, laptops is now massive and continuous in everyday life. It, therefore, becomes increasingly important to be aware of the performance of these devices, not only in terms of the tasks to be performed but also in terms of interaction with humans and therefore knows any possible effect on the ergonomics of vision. Following previous research activities conducted by the authors on the assessment of the visual ergonomics at video display terminal workstations, the aim of this study is to evaluate the ergonomics of human-system interaction of laptop displays. In details, a sample of 57 laptop displays is analyzed in accordance with the requirements of the EN ISO 9241-3xx series of international standards related to the display luminance, luminance ratio, contrast non-uniformity. An extensive luminance measurement campaign was carried out using a special pattern that allowed to measure the luminance in 13 different areas of the displays. The results obtained with this activity showed a great luminance variability between different displays. Almost all the displays are able to emit high levels of display luminance, and almost all the displays meet the requirement of contrast non-uniformity. However, several devices did not meet the recommended values of luminance ratio. Furthermore, the authors created a simplified graph to allow a rapid evaluation of the performance of the displays. This method could be periodically used in practice in order to evaluate the residual performance level.Data Paper Citation - WoS: 3Citation - Scopus: 4Experimental data showing the thermal behavior of a flat roof with phase change material(Elsevier, 2015) Tokuç, Ayça; Başaran, Tahsin; Yesügey, Sadık CengizThe 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.

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 SASConference Object Citation - WoS: 2Citation - Scopus: 2A Case Study on the Selection of Optimum Loop Units for the Deployable Arch Structures Exposed To Lateral and Non-Uniform Gravity Loads(Elsevier, 2020) Yuceturk, K.; Aktas, E.; Maden, F.; Gur, S.; Mitropoulou, C. C.Radially deployable arches may be created by using various types of units. However, for any deployable structure to be constructed in real life, it should satisfy the structural regulations and codes. Despite various advantages from architectural perspective, deployable structures are weak to satisfy the operational code limits when compared to trusses with similar height and span. Therefore, weight minimization is very important to reduce the dead loads of the structure which facilitates the code-conformance of the structure. The optimization of the deployable structures requires an initial selection of the loop types to define the structure parametrically. An initial selection strategy depending on the loads on the structure is important to increase the efficiency of optimization process. Under uniform gravity loads, optimum arrangement for each unit type converges to a similar point. However, in the real world, the loads on the arches are not always uniform and the structure is exposed to nonuniform loadings such as point loads or lateral loads. This work focuses on the performance of various arches with different unit types under lateral and non-uniform vertical loads. Different lateral load and non-uniform gravity loading scenarios are created. For each scenario, the arches with different units are analyzed. In all cases, clear span and height are kept as same. The performance of an arch with a specific unit type for a given load is measured with a score that includes the deformations and the weight of the structure. All the members are assumed to be circular hollow sections with variable diameter and thickness to have a meaningful weight comparison between structures. This work intends to define an initial selection guide for deployable arches under typical non-uniform and lateral loading conditions. (C) 2020 The Authors.

Especially, conscious decisions in earlier design stages are more significant due to lifespan impact of buildings. Deficiencies in systematic approach for design decision support to increase energy and environmental performance of buildings are projected as the major problems of this study. Decisions for performance-based design should be made in terms of the most effective design parameters peculiar for each project. This study exemplifies the act of design decision support in early design stage of a residential building in Turkey. The relation between design parameters and annual energy consumption for heating, cooling and annual operational CO2 emissions is examined by global sensitivity analyses for the present, 2020s, 2050s and 2080s weather conditions. Design process requires the assessment of the uncertainties in building performance caused both by design parameters and climate change. The results indicate that the decisions about solar heat gain coefficients (SHGC), and heat transfer coefficients (U) of transparent surfaces on building envelope have the highest impacts on energy and environmental performance of residential buildings in hot-humid climatic conditions.Book Part Citation - Scopus: 2Ventilation Strategies for the Preventive Conservation of Manuscripts in the Necip Paşa Library, Izmir, Turkey(Elsevier, 2018) Coşkun, Turgay; Şahin, Cem Doğan; Gülhan, Özcan; Durmuş Arsan, Zeynep; Gökçen Akkurt, GüldenLibraries are specific spaces in which the indoor microclimate should meet rigorous requirements such as the thermal comfort of humans and the conservation of books, manuscripts, and cultural property. An inadequate indoor microclimate (mainly temperature, relative humidity, and their fluctuations) in libraries may cause chemical, biological, and mechanical degradations in paper-based collections. In this chapter, the indoor microclimate of the Necip Paşa Library, the historic library located in Tire-Izmir, Turkey, is discussed from the perspective of the preventive conservation of manuscripts. The library, which has no active heating, cooling, and ventilation system, was modeled with the help of a building energy simulation tool, DesignBuilder. The indoor temperature and relative humidity were monitored throughout 1 year and the model was calibrated with respect to these measurements. To reduce the risks of the manuscripts degrading, ventilation strategies were proposed including natural and mechanical control. The results showed that risks of chemical degradation can be diminished to some extent. © 2018 Elsevier Inc. All rights reserved.
