Confort climático, cambio climático y actividad turística en Alicante
2016
Ponencia presentada en: X Congreso de la Asociación Española de Climatología celebrado en Alicante entre el 5 y el 8 de octubre de 2016. [ES]Los rasgos climáticos son esenciales para comprender la vocación turística de los territorios. En el litoral mediterráneo desde los años sesenta del siglo XX hay una especialización en el producto turístico basado en los rasgos climáticos de verano (sol y playa). La provincia de Alicante es un destino turístico principal en el área mediterránea española y esta actividad representa el 18% de su PIB provincial. Las condiciones climáticas actuales proporcionan valores de confort climático, según el índice TCI, muy buenos o excelentes durante la temporada …
A case study to the Evaluation of Global Environmental Quality, concerning thermal, acoustic and atmospheric conditions of urban areas
2013
In this paper we propose an operative procedure aimed at assessing and check the global environmental quality in the urban areas. This methodology is set up by using an ergonomic approach that analyses the interaction man-environment in terms of cause-effect and uses information and data from various sources contributing to the formation of discomfort degrees.[1-2] The representation technique by normo-grams is used for showing some applications executed along the urban territory of Palermo and allows to evaluate very simply all the parameters involved in human comfort. This paper is divided in 5 sections, after the introduction in section 2 a review of the principal simple and complex inde…
Analyses of phase change materials’ efficiency in warm-summer humid continental climate conditions
2017
The usage of phase change materials (PCMs) is a way to store excess energy pro- duced during the hot time of the day and release it during the night thereby reducing the overheating problem. While, in Latvian climate conditions overheating is not a big issue in traditional buildings since it happens only a couple of weeks per year air conditioners must still be installed to maintain thermal comfort. The need for cooling in recently built office buildings with large window area can increase signi cantly. It is therefore of great interest if the ther- mal comfort conditions can be maintained by PCMs alone or with reduced maximum power of installed cooling systems. Our initial studies show tha…
Experimental testing of phase change materials in a warm-summer humid continental climate
2019
Abstract The construction industry (and buildings) is one of the largest energy consuming and CO2 emitting sectors in the world. To counter this, more lightweight structures are being used and energy saving applications are being developed. Phase change materials (PCM) are materials that can be considered to tackle these new challenges. It has been proven that PCMs can be passively used to improve the thermal mass of lightweight structures, which improves thermal comfort and reduces peak cooling and heating loads and therefore provides energy savings. To use these materials in an active way, they should be used together with ventilation, cooling or heating equipment, and collectors to accum…
IL COMFORT INDOOR, STRUMENTI LEGISLATIVI: PANORAMA LEGISLATIVO INTERNAZIONALE E NAZIONALE
2022
Già da qualche decennio si parla di IEQ (Indoor Environmental Quality) con particolare attenzione sulla salubrità dell’ambiente costruito e alla sua possibile influenza sulla sostenibilità ambientale. Tale interesse si è riversato per lo più sulla qualità dei prodotti e delle tecnologie dell’edilizia, incentrando la questione sulle prestazioni di essi e sugli effetti ambientali che essi generano. Con gli obiettivi previsti dall’Agenda 2030 si supera l’idea che la sostenibilità sia una prerogativa ambientale e si afferma una visione olistica mirata alla salute umana (obiettivo 3), emergendo la necessità di un passaggio da un approccio “Green” al costruito verso un approccio “Human Centred” c…
Indoor Comfort in School Buildings: The Case Study of Palermo
2014
Buildings primary energy consumption in developed countries accounts for about 40% of whole uses. Therefore, the European Union has released many regulations, concerning energy saving issues; particularly, it has enacted Directive 2002/91/EC regarding the energy performance of buildings, and its Recast Directive 2010/31/EU, that promotes the Nearly Zero Energy Building targets, introducing more strict parameters in this aim. Furthermore, the latter Directive asks Member States to include within their national plans measures aimed at supporting public authorities to become early adopters of building energy efficiency improvements. In the same time, Public Authorities should implement effecti…
Il BIM nella Progettazione Sostenibile
2017
Il Building Information Modeling (BIM) è un sistema di progettazione integrata che usa tecniche di modellazione parametrica, associando a ogni elemento costruttivo una descrizione delle caratteristiche geometriche, dei materiali impiegati, dei costi di produzione, ecc. Ma è anche un’attività umana, che sta determinando consistenti modificazioni dei processi nel settore delle costruzioni. L’articolo presenterà i risultati di uno studio che si sta conducendo nell’ambito del Corso di Laurea in Ingegneria Edile –Architettura dell’Università degli Studi di Palermo, sulle potenzialità e i limiti che il BIM può determinare per il risparmio energetico. Attraverso l’approfondimento di un caso studio…
Chicago e la tradizione dei vetri decorativi: Louis Comfort Tiffany e Frank Lloyd Wright
2012
Pensando all’arte sviluppatasi in America a cavallo tra Ottocento e Novecento non possono non venire in mente le figure di Louis Comfort Tiffany e Frank Lloyd Wright, due grandi protagonisti di quel tempo passati alla storia come pionieri, il primo nell’ambito delle arti decorative e il secondo nello specifico architettonico, ma ancora oggi fonte di ispirazione per designer all’avanguardia.
Fuzzy motion control strategy for cooperation of multiple automated vehicles with passengers comfort
2008
This paper considers motion control for a cooperative system of automated passenger vehicles. It develops a cooperative scheme based on a decentralized planning algorithm which considers the vehicles in an initial open chain configuration. In this scheme the trajectories are intersections-free, and each trajectory is planned independently of the others. To ensure the stabilization of each vehicle in the planned trajectory, a fuzzy closed loop motion control is presented, where, based on the properties of the Fuzzy maps, the Lyapunov’s stability of the motion errors is demonstrated for all the vehicles. Based on the ISO 2631-1 standard, the saturation property of the Fuzzy maps guarantees lo…
Measurements of projected areas of seated and standing people of southern Italy based on a statistical analysis
2006
One of the most important components affecting the human thermal balance is represented by its radiative exchange with the surrounding surfaces. The projected area of the human body is an important parameter of these thermal exchanges. Unfortunately, although the anthropometric measures of people are characterized by significant differences among various populations, the experimental data currently available in the literature refers to a small group of people. Moreover, measurements are generally performed regardless of the statistical significance of the involved subjects with respect to the population to which they belong. In this study, a statistical study is introduced that is based on …
