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.
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…
STCMS: A Smart Thermal Comfort Monitor For Senior People
2020
Undoubtedly, the steady increase in the number of elderly people is not to be underestimated. These demographic changes call attention to new challenges regarding adequate aging-in-place strategies. Since the majority of the senior population spend up to 90% of their time indoors, appropriate and comfortable housing represents an important foundation for such strategies. In this respect, different types of data gathered from sensors, connected devices, and Internet of Things (IoT) technologies come to play an important role to support services for the elderly population in indoor environments. One of the aspects of concern is thermal comfort. In this paper, we introduce a new deep learning-…
Foot Temperature Assessment
2016
Thermographic studies of the foot can be very useful in 3 different ways: in preventing injury, in analyzing sporting technique and in assessing the effects of footwear and clothing. The aim of this chapter is to discuss several methodological points concerning the thermal analysis of the foot using infrared thermography, as well as to discuss how it can be applied to the science of sports, both in areas already researched and those as yet uninvestigated.
A survey on the thermal conditions experienced by a surgical team
2007
The complex environment of the operating theatre is shared by a group of people having highly different needs: on one side, there is a surgical team whose work may last many hours and, on the other, an anaesthetized patient often subject to liquid infusion. Up to now, little consideration has been given to the different needs of the surgical team who may be affected according to their positions with respect to the scialytic lamp and their particular task. Clothing influences the comfort of the surgical team to a considerable degree: in fact, in some surgery (orthopaedics, neurosurgery and so on), surgeons and assistants must wear paper overalls beneath non-breathable plastic overalls and p…
The preservation of the artistic heritage within the seat of the Chancellorship of the University of Palermo. A proposal on a methodology regarding a…
2006
The correct maintenance of artworks of historical and artistic value requires a wide and detailed analysis of all the information relevant for preserving them, such as identification of the main deterioration factors, knowledge of the climatic history of the object, set-up of measuring methods and statistics of the guide parameters, and definition of a set of recommended environmental aspects to be controlled within a stable climate condition linked to the particular kind of object or its surface. In Italy, the basic laws UNI 10829 and UNI 10969 impose a reference methodology for the in-field measurement and data analysis. This paper reports the first results of a measuring campaign, carrie…
