According to statistical data reported by the Japanese government, the major causes of death for Japanese people are cancer, heart disease and cerebrovascular disease. The incidence rate of cerebrovascular disease in particular is higher during winter than summer (Hayama, 2011). One possible reason for this seasonal difference is that exposure to low temperatures can cause fluctuations in blood pressure. In houses with poor thermal insulation, indoor temperature differences between heated and non-heated spaces, such as the bathroom, corridors, and lavatory can be larger during winter. Many houses in the Tohoku region have a poor thermal environment during winter, and the incidence rate of cerebrovascular disease in this area is the highest compared to the other areas in Japan. Hasegawa and Yoshino (1985) investigated indoor thermal environment in houses of Yamagata prefecture, which is included in Tohoku region, during the heating season and the death rate of cerebrovascular disease in 1983 and 1984. As a result, the temperature difference between the heated living room and the unheated rooms was found to be great. Also it was revealed that if the lavatory temperature was low or the bedroom was not heated, the occupants living in such houses statistically tended to be susceptible to cerebral vascular accident. In order to clarify the association between the indoor environment of residential buildings and cerebrovascular disease, an epidemiological survey of 188 elderly persons living in Yamagata Prefecture in the Tohoku region of Japan was conducted. The specific areas investigated included three rural towns (former Yahata town, former Haguro town and Asahi town) and these areas are same as the investigated areas about 30 years ago. The survey was divided into three phases. The first phase (Phase 1) was a cross-sectional questionnaire on housing characteristics related to the indoor thermal environment and occupants' lifestyle habits among elderly persons. This paper describes the results obtained from this questionnaire and presents the characteristics of the indoor thermal environment and occupants' lifestyle habits during winter. Moreover, an association between the increase in rate of death due to cerebrovascular disease and factors that influenced the indoor environment of houses is examined using multivariable logistic regression analysis. The multivariable logistic regression analysis shows that always feeling a draft in the living room while operating heating equipment (AOR, 8.14; 95%CI, 1.55-42.8) and low temperature in a living room at morning (AOR, 0.87; 95%CI, 0.78-0.98) was positively associated with an increased rate of death due to cerebrovascular disease for former Yahata town. These results indicate that a poor indoor thermal environment may contribute to an increase in the rate of death due to cerebrovascular disease. In addition, a high salt diet may contribute to the onset of cerebrovascular disease. When participants moved from a living room to a bathroom during winter, they reported thermal sensations, such as ‘warm’, ‘neutral’ and ‘cold’. AOR for ‘cold’ when entering a bathroom (AOR, 0.17; 95%CI, 0.05–0.58) was significant for former Yahata. These results indicate that occupants in this town did not feel cold, although the indoor temperatures among surveyed towns were similar. AOR for light clothing when staying at home was significant for former Yahata town and participants were thinly dressed during heating season. Therefore they may be more readily exposed to a cold indoor environment than other towns.

This study explored changes in spatial radiation dose rate both indoor and outdoor associated with a decontamination operation for a wooden house in a high dose rate region in Fukushima. As a result, the averaged spatial dose rate at 1m height from the floor before the decontamination was 1.73μSv/h and the dose rate after the decontamination was 0.86μSv/h. Furthermore, the results of a comparison of the dose rate between pre- and post-decontamination indicates a decrease in the dose rate at almost all points. The reduction rate of spatial dose-rate was 40 to 50% at the center of the house.

This study aims to clarity the thermal characteristics of the heat storage concrete using mat foundation of solar house based on the measurement survey through a year and the three dimensional unsteady heat conduction numerical analysis considering heat exchange between the concrete and the soil. The characteristics of the room air temperature under several operation modes of the solar system controlled by the room air temperature, the outdoor air temperature and the temperature in the ridge duct were clarified based on the measurement survey. It was clarified by the numerical simulation that the consideration of the heat exchange between the concrete and the soil was important to know the heat exchange characteristics of the heat storage concrete and the most of the cold supply heat from the concrete to the room was originally from the soil. It was also clarified that the heat quantity less than a half of the whole heat quantity stored in the concrete contributed to heating of the room and the remainder moved to soil during heating season. Moreover, several interesting findings were obtained about the relationship between the heating and cooling performance of the heat storage concrete and the thickness of the concrete/the existence of the thermal insulation under the concrete.

The previous paper confirmed that the local dynamic similarity model can predict discharge coefficients, which vary with wind direction and opening position, if some requirements are met. Four types of wind tunnel experiments were carried out in this study to investigate how strictly these requirements have to be met when the model is applied to inflow openings. If was thus found that the model should not be applied when the opening is in a flow separation region, because it does not consider the effect on the discharge coefficient of recalculating flow generated by flow separation. It was also found that the effects of the direction of flow tangential to the opening, the profile of this flow over the opening and a wall hindering the diffusion of incoming air flow near the opening were generally small or negligible. Thus, there are no substantial problems in applying the model when the direction or profile of the tangential flow is changed or when there is a wall near the opening.

Under warm conditions, ceiling fans and cooling panels provide an inexpensive method for improving human thermal comfort. It is expected that ceiling fans and cooling panels controlled automatically according to thermal comfort indices can keep occupants' thermal comfort at a certain level, even under changing conditions. In this paper, two indices used for control were evaluated. One was the PMV and the other was the mean body temperature (Tmb) simulated with the 2-node model. Based on experiments with eight human subjects, the study showed that a ceiling fan system controlled according to the PMV could maintain a neutral thermal sensation in a transient environment. The Tmb-controlled ceiling fan system was not better than the PMV-controlled system. The PMV-controlled cooling panel system worked well for subjects' thermal sensation and comfort, whereas the Tmb-controlled cooling panel system could not maintain a stable ambient temperature. Subjects' thermal sensation fluctuated according to the swing of the ambient temperature. The combined system of a ceiling fan and a cooling panel was proposed as a better solution: the draught caused by the ceiling fan and the slow response of the cooling panel under changing conditions. The control of the combined system was based on the PMV. The air speed under the ceiling fan that was usually kept at 0.8m/s for energy saving, resulted in more than 80% of the subjects finding the conditions acceptable in the ceiling fan experiment. The cooling panel was controlled to be PMV=0, assuming that the air speed was 0.8m/s. The ceiling fan was controlled to increase or decrease the air speed from the 0.8m/s for rapidly changing conditions. The combined system kept subjects' thermal sensation neutral, and maintained subjects' thermal comfort. The PMV proved to be a good index to control devices to maintain occupants' thermal comfort, except when the occupants' thermal sensation deviated too much from thermal neutrality, e.g. immediately after the devices were started, or just after the occupants entered from outside.

Introducing air conditioners to school classrooms is proceeding for avoiding heatstroke. The introduction of air conditioner to school gymnasiums has started as well. The field measurements of thermal and air environment in schools were conducted in the area of Hokkaido, Tohoku, Hokuriku, Kanto and Kyushu. It was found that the risk of heatstroke in classrooms in Hokkaido area was observed. The popularization of ventilation equipment to classrooms lags behind compared to the air conditioners. The ventilation equipment is useful for measures of flu and COVID-19. The field measurements were conducted both in classrooms with ventilation equipment and those without them. The ventilation rates after COVID-19 were increased compared to those before COVID-19.

Our experiments demonstrated that there were both short-term (temporary) and long-term (accumulative) effects of temperature and humidity exposure on skin moisture. As the short-term effect, it was found that skin moisture content increased due to not only high indoor absolute humidity but also high indoor temperature. The increase in skin moisture content with high indoor temperature could be attributed to the increase in the moisture diffusion coefficient in stratum corneum according to the Arrhenius relationship. As the long-term effect, it was found that the skin moisture content was decreasing as the season changed from summer to winter. This phenomenon was considered to be due to the long-term change of the equilibrium moisture content of stratum corneum.

In order to establish a new human thermophysiological model which can predict not only body temperature but also blood pressure and blood flow rate, we conducted reference data collections through some experiments and field surveys, and developments of the sub-models which compose our new model. In the experiments and field surveys, we obtained detailed physiological data under six steady-state and two unsteady-state conditions, and data on the daily life fluctuations of exposure temperature, blood pressure, etc. in winter. As the sub-model developments, we improved the thermal network and cardiovascular models, and verified their applicability. In addition, we developed a prototype of the physiological model to simulate the regulations of sweat, blood pressure and blood flow rate.

First, simultaneous measurements of outdoor thermal environments and physiological responses of walking pedestrians were conducted and the relationships between the thermal environments and the physiological responses were determined. Secondly, the validation of the human thermoregulation models was performed in order to select the suitable models for heatstroke and thermal comfort evaluation of walking pedestrians.Lastly, a new prediction method of outdoor thermal environments based on the viewpoint of “suppressing heat stress increase of walking pedestrians to keep thermal environment in outdoor space within acceptable range” was developed by using these models and coupled simulations of radiation, conduction and convection. Based on this method, a study of the most suitable arrangement of cool spots and the evaluation of countermeasures against urban warming in a certain street in the Shimbashi area was conducted.

There are two aspects to the countermeasures against urban warming: mitigation and adaptation. Moreover, urban warming is caused by both global warming and urban heat islands (UHIs). This study proposed a system to assess the effects of countermeasures used to mitigate global warming, mitigate UHIs, and adapt to urban warming simultaneously. Moreover, an evaluation method for outdoor health risk in the extremely hot days was developed. In this study, to distinguish between hazards that cannot be controlled by humans and those that can be controlled by modification of urban structures, “natural hazard” and “actual hazard” were defined, respectively. Using the assessment systems, the effects of countermeasures were evaluated. Finally, the priority of measures for appropriate design of outdoor urban environment under future climate conditions was concluded.

In order to clarify the association between the indoor environment of residential buildings and cerebrovascular disease, an epidemiological survey of approximately 200 elderly persons living in Yamagata Prefecture of Japan was conducted. The survey was divided into three phases. From first phase, an epidemiological survey of 188 elderly persons living in three areas that have different rates of death due to cerebrovascular disease was conducted. Results indicate that poor quality of the indoor environment during winter could increase the risk of cerebrovascular disease.The results obtained from the final phase, which included field measurements of indoor temperatures and blood pressure of 30 elderly persons during one year. Results indicate that in most houses, that the indoor temperature at daybreak can be as low as the outdoor temperature. The systolic blood pressure of elderly persons was shown to be positively associated with exposure to temperatures lower than 15°C.

In order to prevent health problems caused by severe thermal environments, we developed a new human simulation model, which can predict not only body temperature but also blood pressure and blood flow rate. We also carried out some subjective experiments to collect reference data for the development. The experiments were done in 9 cases with different combinations of ambient temperature and body posture, and some physical quantities, e.g. body temperature, blood pressure, blood flow rate, were measured. The new human model was designed to be composed of a physical model and physiological model, and besides, the physical model was designed to be composed of a thermal network model and cardiovascular model. In this study, the thermal network model and cardiovascular model were developed, and it was confirmed that the models were able to reproduce the subjective experiments reasonably.

We conducted questionnaire survey and field measurements on 6 cities in China. Results of the questionnaire survey suggested the association between mold and chemical pollution and children’s allergic diseases. The results also showed that the prevalence of allergic diseases in southern three cities was higher than that in northern three cities. On the other hand, results of the field measurements showed that there was no difference in air concentrations of fungus and chemical substances between the groups with and without allergic diseases. However, concentrations of TVOC and PM2.5 were higher in southern cities than in northern cities, and it is not contradictory to the prevalence of allergic diseases. Measured indoor temperature and humidity suggested that Chinese houses were little improved on thermal insulation but reduced air change rate in this decade. We proposed the minimum thermal resistance of houses for preventing winter dew condensation from the aspect of mold prevention.

In order to verify that arousal state is one of the human responses mediating causal relationship between IEQ (Indoor Environmental Quality) and work performance, three subjective experiments were carried out. Results showed that (1) arousal state varies due to IEQ, (2) work performance improves with increase in energetic arousal and falls with increase in tense arousal, (3) simple work calm down both energetic and tense arousal and the resulting arousal states are almost the same under different IEQ conditions, while complex work increase both energetic and tense arousal and the differences in the resulting arousal states due IEQ are clearly observed.

The field experiments, wind tunnel experiments and image analysis have been carried out. The findings of the study can be summarized as follows. (1) The local dynamic similarity model can predict discharge coefficients, which vary with wind direction and opening position, if some requirements are met. Four types of wind tunnel experiments were carried out in this study to investigate how strictly these requirements have to be met when the model is applied to inflow openings. There are no substantial problems in applying the model when the direction or profile of the tangential flow is changed or when there is a wall near the opening. (2) The local dynamic similarity model was coupled with a COMIS network model. The prediction accuracy of ventilation flow rates was verified for one-zone and two-zone building models. The coupled model achieved better predictions of discharge coefficients and ventilation flow rates than the conventional orifice flow model. (3) The airflow characteristics outside and inside a cross-ventilated room were measured by ultrasonic anemometers in summer 2006. The major contributions to the energy spectra of cross-ventilation are revealed in the frequency range less than 0.1Hz and that the energy spectra of cross-ventilation contain some region of wave numbers with an exponential decay of k-5/3. (4) When the air velocity was more than 0.5m/s, various air velocity changes and airflow fluctuations in time and space made subjects feel more comfortable under cross-ventilation than under airflows from the air-conditioning system. (5) The influence of air velocity fluctuations on surface temperature fluctuations of thermal mannequin was visualized in the experimental room under cross ventilated cases and under air conditioned cases. An image processing method to transfer the infrared animations to power spectrum images was proposed in order to clarify the frequency of surface temperature fluctuations. (6) The influence of building coverage ratio on ventilation performance was small rather on roofs than on walls. A roof window was found to be a very effective tool for increasing ventilation flow rates especially in densely populated area.
