Assessing the effectiveness of green roofs in enhancing the energy and indoor comfort resilience of urban buildings to climate change: Methodology pr…

2021

Abstract The effects of climate change on the built environment represents an important research challenge. Today, green roofs (GRs) represent a viable solution for enhancing energy and urban resilience in the face of climate change, as they can have a positive impact on the building's indoor thermal comfort and energy demand, as well as inducing various environmental benefits (easing urban heat island effects, improving the management of runoff water, reducing air pollution, etc.). Thus, it is important to be able to assess their effectiveness, both today and under future climate conditions, in order to evaluate whether they can also provide a valid long-term solution. In this paper, a sim…

Monitoring of the effect of solar radiation and rain on the building envelope with integrated vertical vegetation

2022

The goal of the present paper is the verification of the improvement of the performance of a building envelope with a green wall also in conditions of high irradiance (≥0.6 kW/m2) and with variable meteorological conditions (sunny, cloudy, and rainy), with a focus on intense rainfall and tempest. The object of the analysis has been the Innovation and Technology for Development Center in the University Campus of the Polytechnics of Madrid, where a modular system of integrated vertical vegetation has been installed on the skin of the South and West prospects. The study is based on the analysis of the effective thermoregulation capacity of the system in different climatic situations and has be…

Robust dynamic comfort modeling for motorcycle riding

2015

Comfort modeling is considered a prerequisite in motorcycle design, primarily to address safety concerns and to position the product on the market. However, a comprehensive methodology for comfort modeling during the earliest development phases of a motorcycle model is still missing. Anthropometrical variation is the main noise factor to consider in comfort modeling in relation to the unavoidable variability of body segments. However, comfort is a subjective concept influencing riders' choice of motorcycle model. This work is a generalization of the robust ergonomic design methodology aimed at designing products whose ergonomic performance is insensitive to anthropometrical variation. This …

Radiative heat exchanges of people in complex geometry buildings: An experimentally based algorithm for computing angle factors

2008

Thermal comfort of people working or living in confined spaces depends, to a large extent, on the radiative thermal exchanges. These contributions are expressed, among other things, as a function of the mean radiant temperature that, in the general cases where there is a presence of high intensity sources, must be expressed as a function of the angle factors between subjects and the surrounding surfaces of enclosures. Angle factors, in turn, depend on the projected area factors. Despite this evidence, at the present there is a lack in the availability of simple and reliable methods capable of computing angle factors of people in assigned postures with respect to complex geometry buildings. …

An MAS-based subjective model for indoor adaptive thermal comfort

2015

The achievement of high level personalized sets of comfort parameters is contemplated within the more general context of the so-called smart buildings, where people, by means of the new communication technologies, become active actors to the process of the singling out and control of the best indoor conditions. This Dynamic Intelligence approach would usefully contribute to a better energy efficient and environmental friendly management of buildings. Multi-Agent schemes are suitable tools in this aim, since they are able to manage the user-building-plant system where the adaptivity of people to the indoor conditions is suitably achieved. In this paper a contribution to a development of the …

Assessment of a mattress with phase change materials using a thermal and perception test

2017

Abstract Mattresses composed by phase change materials (PCMs) may improve the thermoregulation of the human body. The aim of the study was to analyse the thermoregulatory efficiency of a PCMs and a conventional mattresses via the evaluation of the skin temperature, thermal comfort and thermal perception. Twenty participants lay on a PCMs and a conventional mattress for 20 min in each mattress on the same day. Skin temperature of the back of the participants and temperature of the sheet of the mattresses were measured before and immediately after lying on each mattress. Thermal comfort and thermal perception were also reported during the last minute of the lying test. The PCMs mattress resul…

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…

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 …
