“…O tema do conforto térmico (condição mental que expressa satisfação com o ambiente térmico envolvente) tem sido investigado nos mais variados contextos, no sentido de procurar a maximização do conforto térmico de espaços interiores/exteriores, associado à necessidade de redução de consumos energéticos e ao desenvolvimento de soluções arquitetónicas que garantam a segurança, o conforto e a saúde dos indivíduos (M. Castilla et al, 2011;D. Daum et al, 2011; J.…”

“…A sensação térmica (indicação da perceção da transferência de energia sob a forma de calor entre o corpo e o ar envolvente) é uma característica muito própria de cada indivíduo, que está relacionada com o balanço térmico do corpo humano e, por isso, é dependente é influenciada por vários fatores relacionados com o ambiente térmico (conjunto de variáveis termohigrométricas) e com fatores pessoais, sejam eles físicos, psicológicos e/ou fisiológicos (M. Castilla et al, 2011). Com base nestes pressupostos as diferentes zonas de conforto térmico dependem de componentes subjetivas e individuais ou quaisquer especificidades locais/contexto (T. Starling et al, 2013).…”

RESUMOO desconforto térmico é uma causa de insatisfação no trabalho fortemente associada a riscos de acidentes de trabalho.É neste contexto que o presente trabalho se insere, tendo como objetivo, através de índices térmicos, a identificação do padrão térmico dos espaços em estudo e dos postos de trabalho com maior risco a stress térmico, bem como ao conhecimento das sensações térmicas dos trabalhadores. O Departamento de Higiene e Segurança das indústrias estudadas valorizou os resultados para criar medidas que satisfaçam as necessidades em termos de conforto. Palavras-chave:Desconforto térmico, índices térmicos, padrão térmico, EsConTer, ITH. ABSTRACTThermal discomfort is a cause of work dissatisfaction related to work accidents risk. This paper aims to identify, regarding thermal indexes application, the thermal patterns of the spaces in study, the most critical workstations as well as the workers thermal sensation. The Hygiene and Safety Department of the industries in study valorized the results in order to satisfy workers comfort needs.Keywords: Thermal discomfort, thermal indexes, thermal pattern, EsConTer, ITH. RESUMENRiesgo de estrés térmico en un ambiente caluroso en contexto industrial -La incomodidad térmica es una causa de la insastifacción laboral, fuertemente asociada con el riesgo de accidentes de trabajo. El actual estudio se desarrolla en este contexto y tiene como objectivo, através de los índices térmicos, la identificación del patrón térmico de las áreas de estúdio y los trabajos con mayor riesgo de estrés por calor, así como el conocimiento de las sensaciones térmicas de los trabajadores. El Departamento de Salud y Seguridad de las empresas estudiadas ha apreciado los resultados obtenidos para crear medidas ayuden a promover la comodidad de sus trabajadores.Palabras clave: Incomodidad térmica, índice de calor, patrón de calor, EsConTer, ITH. RÉSUMÉLe risque de stress thermique sur les environnements chauds dans les industries -L'inconfort thermique est une cause de mal-être au travail et un facteur de risque d'accidents du travail.

“…Sourbron et al simulated using TRNSYS and investigated whether, for a moderate climate and with the heating and cooling set points chosen according to the adaptive models, the building"s energy use reduces or not and found that ASHRAE55 and the ISSO74 adaptive thermal comfort models do not result in energy savings, for a moderate climate and for office buildings with a cooling load throughout the year and it can be concluded that applying these adaptive thermal comfort models does not offer benefits compared to the basic non-adaptive thermal comfort model of ISO7730 [62]. Castilla et al presented a comparison among several predictive control approaches that allow for obtaining a high thermal comfort level optimizing the use of an HVAC system by means of different cost functions [63]. Mors et al [64] conducted a Field Survey and Statistical Analysis to investigate the thermal comfort and thermal comfort parameters for children in non-air-conditioned classrooms in three different primary school in Eindhoven, the Netherlands and found that PMV method underestimates thermal sensation for children, with an error largest in summer with underestimation ranging from 0.5 -1. made a field survey to develop adaptive thermal model based Actual Mean Vote (AMV) and Thermal Balance Model based (PMV) for three different climatic zones of North-East India and developed an adaptive coefficient which could relate the survey based comfort votes and Fanger"s PMV [7].…”

Abstract-The primary function of a building is to provide thermally comfortable environment to its occupants. A good indoor climate is important for the success of any building, not only because it will make its occupants comfortable, but also because it will decide its energy consumption, and thus influences its sustainability. A literature review of over 100 research papers, in four areas in the field of Energy Conservation in Buildings, i.e. (i) Climate Responsive Buildings, (ii) Analysis, Simulation and Modelling, (iii) Zero Energy Buildings and (iv) Thermal Comfort, were conducted in order to obtain a valid research topic. The findings of the literature survey is presented in this paper which include issue wise discussion, solution approaches used by various researchers, strengths, weaknesses and future scope of work in the four issues pertaining to energy conservation in buildings. Out of the several identified lag, it was felt that there was a dearth of field studies based thermal comfort research in India, which is essential for the correct definition of building codes. Proper building codes are required not only for providing comfort condition but also to conserve energy. Hence field studies based thermal comfort study was considered for further research study. Thus, this paper summarizes the researches about Climate Responsive Buildings, Analysis, Simulation and Modelling, Zero Energy Buildings and Thermal Comfort. It also concludes the methodology of these researches in above four fields, and gives further work suggestions.

“…In previous works, different predictive control strategies have been compared by the evaluation of several cost functions [29]. Concretely, in that work, the main goal was to maintain thermal comfort within an appropriate zone defined by the PMV index minimizing, at the same time, energy consumption.…”

An Economic Model-Based Predictive Control to Manage the Users’ Thermal Comfort in a Building

et al. 2017

Abstract:The goal of maintaining users' thermal comfort conditions in indoor environments may require complex regulation procedures and a proper energy management. This problem is being widely analyzed, since it has a direct effect on users' productivity. This paper presents an economic model-based predictive control (MPC) whose main strength is the use of the day-ahead price (DAP) in order to predict the energy consumption associated with the heating, ventilation and air conditioning (HVAC). In this way, the control system is able to maintain a high thermal comfort level by optimizing the use of the HVAC system and to reduce, at the same time, the energy consumption associated with it, as much as possible. Later, the performance of the proposed control system is tested through simulations with a non-linear model of a bioclimatic building room. Several simulation scenarios are considered as a test-bed. From the obtained results, it is possible to conclude that the control system has a good behavior in several situations, i.e., it can reach the users' thermal comfort for the analyzed situations, whereas the HVAC use is adjusted through the DAP; therefore, the energy savings associated with the HVAC is increased.
