“…Others [20] attribute the gender effect on thermal comfort to the differences in metabolic rate between two sexes -based on the finding by McNall et al [57] that females have a lower metabolic rate per unit surface area under sedentary activity than males. Physiological differences between the two sexes may have an influence on their thermal responses.…”

“…A field research conducted in Japan identified significant differences in thermoneutrality between the two sexes [33], in which the female group registered significantly higher neutral temperature (25.1°C) compared to the male group (22.9°C). An experimental study on a small sample by Beshir and Ramsey [20] reported preferred temperatures for females significantly higher than those for males. Based on this result they suggested that workspace set-point temperatures need to be slightly higher for predominantly female workforces.…”

This paper investigates the gender differences in the occupants' perception on various aspects of indoor environmental quality (IEQ) by two lines of inquiry; Firstly, a comprehensive literature survey spanning the research areas of indoor air quality (IAQ), sick building syndrome (SBS), thermal comfort, lighting, and acoustics was conducted. Secondly, statistical analyses were performed on a large, predominantly North American Post-Occupancy Evaluation (POE) database (N=38,257).Statistical analyses indicated that female occupants' satisfaction levels were consistently lower than male occupants for all fifteen IEQ factors (including thermal comfort, air quality, lighting, acoustics, office layout & furnishings, and cleanliness & maintenance) addressed in POE questionnaire, and the differences were statistically significant. Logistic regression analysis identified a significant association between female gender and dissatisfaction with individual IEQ factors. Those gender differences quantified by odds ratios (OR) were most pronounced for dissatisfaction with thermal environment, IAQ, and workspace cleanliness. The analyses produced consistent results, even after potential confounding factors such as age and work characteristics were controlled.

“…Even under the same conditions, the increase in body temperature differs between the aged and young 15) , and the working temperature range considered to be comfortable differs between males and females 20) ; therefore, it is difficult to generalize the results of studies in young men, ignoring sex and age. In societies with a decrease in the productive population, hopes are placed on the work of women and the elderly.…”

Effects of Heating Appliances with Different Energy Efficiencies on Associations among Work Environments, Physiological Responses, and Subjective Evaluation of Workload

et al. 2008

To clarify the association between heat stress, physiological responses and subjective workload evaluations in kitchens using an induction heating stove (IH stove) or gas stove. The study design was an experimental trial involving 12 young men. The trial measured ambient dry-bulb temperature, globe temperature, wet-bulb globe temperature (WBGT) and relative humidity; the subjects' weight, heart rate, blood pressure, oxygen uptake, amount of activity, body temperature, subjective awareness of heat and workload before and after mock cooking for 30 min. The IH stove insignificantly increased heat indicators in the work environment and workers showed lower oxygen uptake, skin temperature, subjective awareness of heat and workload after heat exposure. Both physiological load and subjective awareness of heat and workload were slight in kitchens using the IH stove, which provided a better work environment.Key words: Globe temperature, IH stove, Thermal stress, Physiological response, Feeling of load *To whom correspondence should be addressed. MethodsThe subjects were 12 healthy men (22.4 ± 1.0 yr, 172.5 ± 4.8 cm) not acclimated to heat stress. The study design was an experimental trial. The subjects performed mock cooking once using an induction heating stove (IH stove) and once using a gas stove (total, 24 times). This study was approved by The Ethics Committee of Dokkyo Medical University and complied with the Helsinki Declaration. All subjects were fully informed of the purpose, procedures and possible risks of the study, and then gave written informed consent. Mock cooking workThe experiment was performed in a large-scale food practical training kitchen at The University of Tokyo Kasei Gakuin (Fig. 1, 70.15 m 2 in area, studding 2.6 m). An exhaust hood (1,050 × 600, evacuation air-capacity 1,730 m 3 /h) for the upper part of the cooking stove was used in the experiment. The subjects were fasted for 8 h before the experiment. The total weight of clothes (underwear, trousers, socks, T-shirt, chef's coat and work gloves) was 3.1 kg.As shown in Figs. 2 and 3, the subjects stood with the abdomen 45 cm from the center of the cooking plate. The subjects stood for 10 min and stirred boiling water using their right hand for 20 min. The subjects were directed not to change their position. As shown in Fig. 4, they gripped the end of a rice paddle (length, 20 cm) and stirred at an angle of 180˚ at a rate of 10 stirs/min. The left upper limb was extended along the left side of the body.As heat stress, a pan containing 1 kg konjak (alimentary yam paste, 2.0 × 2.0 × 2.0 cm) and 10 kg water was heated, and the state 6 min after the water temperature reached 99˚C was considered to be stable. In the kitchen environment, before exposure to heat stress, the ambient dry-bulb temperature in front of the stove (height from the floor, 120 cm) was adjusted to 25.0 ± 0.5˚C using an air conditioner in each experiment. The full output of the 2-ring gas stove (10,000 kcal/h) was used. To equalize output between the different heat so...

“…Thermal comfort has been defined and studied both in the lab and field, primarily in the commercial sector (Arens, et al, 1998;Brager, Paliaga, & de Dear, 2004;Fanger, 1970;Humphreys & Nicol, 2002;Leaman & Bordass, 2001). Many factors have been found to influence thermal comfort, such as air temperature, radiant temperature, air speed, humidity, level of clothing/activity (American Society for Heating Refrigerating and Air-Conditioning Engineers (ASHRAE), 2004;Fanger, 1970;Nicol & Humphreys, 2009) as well as psychological, behavioral, and physiological influences (Beshir & Ramsey, 1981;Humphreys & Nicol, 1998;Karjalainen, 2007;van Hoof, Kort, Hensen, Duijnstee, & Rutten, 2010). For example, Bae and Chun reported that in Korea comfort temperatures have been increasing in winter and decreasing in summer in the past 25 years due to improvement of the HVAC systems (Bae & Chun, 2009).…”

“…Other human factors play a role in limiting the effectiveness of PTs. For example, gender differences in thermal perception or different needs/schedules of people in a household made it more difficult to find an agreement on the programmed temperature (Beshir & Ramsey, 1981;Karjalainen, 2007Karjalainen, , 2008McCalley & Midden, 2004). Some researchers have proposed the development of goal setting strategies for occupant interactions with PTs (McCalley & Midden, 2004).…”
