“…In India, a study was carried out with young male university students in a semi-controlled environment demonstrating that the PMV model overestimated the actual sensation vote (ASV) of people (subjects are less sensitive -more tolerant-to hot but more sensitive to cold) [179,180]. In South Korea, young adults participated in a study in a semi-controlled environment; PMV presented good correlation with ASV, but not with the votes of thermal comfort (authors stated that PMV may be inappropriate to control the indoor environment in order to establish thermal comfort) [181].…”

“…Conventionally, the predicted mean vote (PMV) model, which has been recommended by American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) [3], has played such a role. However, it has been shown that the generalized human-related factors in the PMV model (the met and clo units for metabolic rate and clothing insulation) could misrepresent actual occupants' dynamics [4,5] during the operations. For example, Humphreys and Hancock [6] have shown that occupants prefer diverse thermal sensations from cold to hot, which is different from the assumption of the PMV model for thermal satisfaction at neutral state.…”

Recent research efforts have shown that human thermophysiological features could play a crucial role in inferring occupants' thermal comfort, which is required for comfort-aware heating, ventilation, and air conditioning (HVAC) operation. Our previous studies have demonstrated that variations of respiration, a representative human thermophysiological feature, can be non-intrusively quantified by a Doppler radar sensor (DRS). However, in pursuit of enabling human-aware rooms in buildings, in this study we have explored the impact of distance and position of the respiration monitoring system to investigate the potential of DRS systems as a ubiquitous apparatus in the realworld scenarios. Through experimental studies, respiration characteristics were evaluated in different locations and angles relative to the location of the measurement device. The measurements were carried out using a DRS system and a respiratory belt for ground truth data collection. The noise artifacts were reduced by applying the Savitzky-Golay method and Hann window, and respiration was identified by selecting the frequency component with the maximum amplitude in the typical breathing frequency range (0.1 to 0.5 Hz). Our analyses demonstrated that the signal from a costeffective DRS technology without the use of external amplifiers could cover a range, within 1.0m longitudinally and 0.5m laterally, which is sufficient for an individual sensing given a normal office environment. It was also observed that the use of an external amplifier extends the range of the DRS sensing but at the same time accentuates the noise. Therefore, advanced noise removal methods are needed to increase the range of robust sensing. This study contributes to DRS deployment strategies for realization of comfort-aware systems.

“…De acordo com outros estudos, o modelo de Fanger pode também apresentar inadequação em espaços condicionados artificialmente de climas subtropicais durante os períodos mais quentes, como em Taiwan (HWANG et al, 2009), Hong Kong (FONG;CHOW;LI, 2010) e Índia (MAITI, 2013(MAITI, , 2014. Na Malásia, o super-resfriamento foi indicado como o principal problema observado nas comparações entre os votos reais e os votos estimados (DAGHIGH; SOPIAN, 2009).…”

“…No norte da Itália (RICCIARDI; BURATTI, 2012), na China (CAO et al, 2011) Com base nessa discussão, é possível concluir que quando se trata de conforto térmico em espaços internos condicionados artificialmente, pode haver discrepâncias entre o que é predito e o que é real. Tais discrepâncias ocorrem com frequência nas edificações de climas mais quentes ou durante os períodos mais quentes em edificações de climas amenos, independentemente do modo de climatização em operação no ambiente (HWANG et al, 2009;HENS, 2009;FONG;CHOW;LI, 2010;CAO et al, 2011;RICCIARDI;BURATTI, 2012;MAITI, 2013MAITI, , 2014 …”
