Evaluation of the indoor comfort of the Arabic-Norman architecture for its valorization
2018
Nel 2015 il percorso arabo normanno di Palermo, Cefalù e Monreale è stato riconosciuto patrimonio dell’Umanità. Tra i monumenti del percorso la Zisa costituisce un esempio straordinario di tipologia edilizia con caratteristiche tecnologiche ed ambientali uniche perché, originariamente, era caratterizzato dall'integrazione di alcuni sistemi passivi per il miglioramento del comfort ambientale interno. Fu costruito nel 1160 da artigiani arabi. Era caratterizzato dalla presenza di un sistema di raffreddamento evaporativo e ventilazione naturale che garantiva livelli di comfort che potevano essere soddisfacenti anche ai giorni nostri. La ricerca propone i risultati ottenuti attraverso l’applicaz…
Digital Twin of HVAC system (HVACDT) for multiobjective optimization of energy consumption and thermal comfort based on BIM framework with ANN-MOGA
2022
This study proposes a novel Digital Twin framework of heating, ventilation, and air conditioning (HVACDT) system to reduce energy consumption while increasing thermal comfort. The framework is developed to help the facility managers better understand the building operation to enhance the HVAC system function. The Digital Twin framework is based on Building Information Modelling (BIM) combined with a newly created plug-in to receive real-time sensor data as well as thermal comfort and optimization process through Matlab programming. In order to determine if the suggested framework is practical, data were collected from a Norwegian office building between August 2019 and October 2021 and used…
Climatic change and thermal comfort. Effects on the tourism industry in the region of Valencia
2020
El cambio climático comienza a manifestar efectos en las actividades económicas de la Comunidad Valenciana. El turismo es una parte fundamental de su economía, puesto que representa el 15% de su PIB regional. La modalidad de “sol y playa” es la principal actividad turística en el territorio valenciano, de ahí la importancia del análisis de las alteraciones que están experimentando los elementos climáticos debido a su efecto en el recurso turístico y en las preferencias de la demanda. La pérdida del “confort climático”, el aumento de las noches “tropicales” (Tª > 20ºC), el incremento de la temperatura del agua de mar Mediterráneo y la adaptación a los extremos atmosféricos (olas de calor, ll…
Comparing indoor performances of a building equipped with four different roof configurations in 65 Italian sites
2020
Abstract—Despite the increasing concern of institutions and technical organizations toward the improvement of the building energy (and, therefore, environmental) efficiency, the main goal of technicians should be also devoted toward the levels of internal thermal comfort that buildings are able to realize. As that, the relationships between energy performances and comfort conditions provided by the enclosures are of paramount importance in guiding designers in their work. In this paper, the influence of diverse roof construction typologies on energy and indoor performance of buildings has been investigated, in different Italian sites during heating and cooling seasons. In addition, it must …
The vegetation for mitigating the microclimate and designing livable and healthy public spaces in Palermo City Centre
2018
Urban morphology and increasing building density play a key role in the overall heat and energy balance of our cities. The urban environment and CO2 emissions resulting from human activities cause a local increase of temperature, a phenomenon known as Urban Heat Island (UHI). This is also due to the reduction of vegetation in urban areas. The benefits that green spaces have in urban planning have been widely acknowledged. In particular, in temperate and hot contexts, plants help to reduce the extreme summer temperatures, improving people’s outdoor and indoor thermal comfort and, at the same time, reducing the buildings’ energy demand for cooling. The way plants affect urban climates is gene…
Natural ventilative cooling in school buildings in Sicily
2016
The paper shows analysis of the impact on thermal comfort of natural ventilation in a nonresidential Mediterranean case-study. Results are based on the EN 15251 approach on adaptive comfort. Different scenarios are proposed, granting an improvement of up to 10% in the number of summer comfort hours.
Liberty winter gardens in Palermo: contamination from solar design
2020
At the end of the 19th century, the city of Palermo boasted a tradition of steel elements that could include the most beautiful railings and light steel structures of the time. The paper shows how the technological, formal and spatial aspects of the metallic construction was derived by the application of Central Europe areas examples to the local reality, providing notions on designs, experimentations and originalities. Canopies, verandas, winter gardens and orangeries are architectural elements in iron and glass that represent an added value for the building, they improve the life quality of the people who live there. In particular, in the Liberty architecture these elements took shape thr…
Thermo-hygrometry and IAQ Related Measurements of the Indoor Physical Conditions of Exhibition Halls for Complying International Rules and Standards
2018
Off-line methods for detecting the indoor physical parameters of museums are important tools in order of continuously monitoring the conditions at which works of art are exposed. These conditions, in fact, are mandatory established by several rules and technical standards aimed at preserving the specific artifacts. Moreover, indoor microclimate parameters must also take into account the comfort conditions for visiting people. Both the above-cited requirements suggest to perform the indoor monitoring with equipment visually low impacting. In this paper, some examples of visually low impacting off-line monitoring methods, applied to three artifacts displayed in the “Museo Regionale” of Palerm…
Does oral health people imparirments modify bolus formation, bolus characteristics and food comfortability of meat products?
2018
International audience; Ageing is often accompanied by oral impairments like tooth loss or decrease saliva flow that play a key role in eating behavior. In the context of aging population, the aim of this study is 1- to understand the influence of dental status and salivary flow on the meat bolus formation and characteristics in function of meat structure, 2- to investigate the link between the food bolus properties and the food comfortability (as defined by (Vandenbergue-Descamps et al., 2017)) during meat consumption. This was achieved by asking elderly people (n=65) with good oral health (17H, 16F, age=73±6, UFP n=8±1) or poor oral health (15H, 17F, age=75±6, UFP n=3±1) to consume 4 meat…
An algorithm for the assessment of subjective adaptive thermal comfort conditions based on multi-agent systems
2011
Thermal comfort conditions in the built environment are strictly related not only to the thermal and geometric building features and to air-conditioning systems, but also to the building destination, to its using profile and to the biological-metabolic-psychological characteristics of users. As a consequence, there is a strong claim for new models, both subjective and adaptive to the environment, in a particular holistic vision of the problem, with regards to the novel tern user-plant-building system. In such a frame, through the paper the characterization of an algorithm aimed at subjective adaptive thermal comfort evaluations, enriching the one proposed by Fanger with an adaptive approach…
