    　View Summary

    近年、低炭素社会への移行が喫緊の課題とされるが、低炭素化対策は経済的負担が大きく普及に繋がっていない。この要因として、低炭素化対策によるCO2 削減効果以外の様々な便益が一般的に認識されていないことが挙げられる。そこで本研究では、高齢化社会への適応という社会的要請にも応えるため、居住環境の改善をもたらす低炭素化対策（Ex. 建築物の断熱・気密化）による健康維持便益（Ex. 医療費節約・欠勤予防）に着目した。その認識と対策の普及に向けて、①居住環境が健康へ及ぼす影響度の解明、②居住環境の改善による健康被害低減の経済性評価を行い、③健康被害低減効果の認識が低炭素化対策の普及に与える影響を解明する。これにより社会の低炭素化・高齢化に適応する新たな居住環境の創出に貢献することを目的とする。

  • THE IMPACT OF INDOOR THERMAL ENVIRONMENT IN WINTER ON DETERIORATION OF CARE LEVEL IN NURSING HOME RESIDENTS A field survey on indoor thermal environment of nursing home and resident’s care condition

    Yukie HAYASHI, Toshiharu IKAGA, Shintaro ANDO and Tanji HOSHI

    Journal of Environmental Engineering (Transactions of AIJ) (Architectural Institute of Japan)  83 ( 745 ) 225 - 233 2018.03

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  1348-0685

    　View Summary

    The Japanese population is ageing, and currently has the world's highest proportion of elderly people. As one consequence, the number of residents in nursing homes is increasing. The Ministry of Health, Labour and Welfare of Japan has identified preventing a need for care as an important aim. The ministry defines “care prevention” in two parts: preventing a care-requiring condition from arising and, when a care-requiring condition already exists, aiming to improve while preventing deterioration. However, mean care level in nursing homes is still increasing, and existing care-prevention strategies are not enough to prevent future increase.
    A field survey was conducted to clarify the effect of indoor thermal environment on the care-requiring condition of residents in nursing homes. Twenty private residential-nursing homes, located in the Osaka, Kyoto, Nara and Hyogo prefectures of Japan, were included in this study. Room temperature and relative humidity were measured over approximately 4 weeks in private rooms, the dining room and other rooms of each facility at 20-min intervals in winter 2015. Additionally, questionnaire surveys were conducted twice, in winter 2015 and winter 2016. In the questionnaire, care level and date of certification of care needs was investigated for all care certifications in effect after occupancy until the time of the survey.
    Most facilities had a relatively warm but dry indoor environment. Fifteen facilities were classified into two groups (warm and cold) based on measured room temperature and two groups (moist and dry) based on measured relative humidity. The Kaplan-Meier method was used to analyse the speed of deterioration (i.e., intensification) of required care level. Residents in the dry facility deteriorated with respect to care level more quickly than residents in the moist facility. In contrast, there was no significant difference according to room temperature. Many factors influence care requirements, including not only the indoor thermal environment but also individual attributes, injury and diseases. To assess these influences, multivariate analysis was carried out.
    Cox proportional hazards regression analysis was used for multivariate analysis to assess the effect of indoor thermal environment on the care-requiring condition of residents in nursing homes. Two questions were evaluated: “Did the care level deteriorate?” and “If so, how long did it take for care level to deteriorate?” The analysis result showed the cold group and the dry group having a higher risk of deterioration of care level. Furthermore, residents in facilities that were both warm and moist had the lowest risk. This result suggests that both temperature and humidity are important for care prevention.
    The study results are expected to contribute to improvement in indoor thermal environments and to care-prevention among residents of nursing homes.

    This study aimed to clarify the impact of indoor thermal environment on sleep quality. Follow-up investigations on sleep quality (sleep efficiency, amount of deep sleep, sleep latency, and number of nighttime awakenings) and indoor temperature were conducted in winter (2014–2016) before and after moving to houses with high thermal insulation performance. Multiple linear regression analysis showed that
    sleep efficiency increased by 0.73% per 1 °C increase in indoor temperature during sleep. Increased indoor temperature also improved the number of nighttime awakenings.

  • Lower Physical Performance in Colder Seasons and Colder Houses: Evidence from a Field Study on Older People Living in the Community

    Yukie Hayashi, Steven M. Schmidt, Agneta Malmgren Fänge, Tanji Hoshi and Toshiharu Ikaga

    International Journal of Environmental Research and Public Health (MDPI)  14 ( 651 ) 1 - 9 2017.06

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  1660-4601

    　View Summary

    The aim of this paper was to explore the effect of seasonal temperature differences and cold indoor environment in winter on the physical performance of older people living in the community based on a field study. We recruited 162 home-dwelling older people from a rehabilitation facility in the Osaka prefecture, Japan; physical performance data were available from 98/162 (60.5%). At the same time, for some participants, a questionnaire survey and a measurement of the indoor temperature of individual houses were conducted. The analysis showed that there were seasonal trends in the physical performance of older people and that physical performance was worse in the winter compared with the autumn. Furthermore, people living in colder houses had worse physical performance. The findings indicate that keeping the house warm in the winter can help to maintain physical performance.

  • Proposal of an evaluation method for resilience improvements considering lifeline supply stoppages: Evaluation of monetary value for resilience improvements by introducing a community energy system

    Kaichi Otsuka, Toshiharu Ikaga, Shuzo Murakami, Ryota Kuzuki, Takahiro Kawayoke

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  1348-0685

    　View Summary

    In urban areas where population and city functions are aggregated, there are calls for the construction of business continuity districts, in which energy supply is secured in times of disaster. A decentralized and self-reliant community-level energy network is expected to contribute to improving resilience and regional vitalization, as well as to reducing carbon emissions. However, the initial investment is high and the stakeholders involved are diverse, creating potential obstacles to the introduction of such an energy network because the necessary measures are of larger scale than a simple construction project. Prior studies have shown the need for accurate recognition of non-energy benefits (NEBs) in addition to energy benefits such as energy cost savings. Moreover, evaluation methods for various co-benefits have been proposed. Yet, NEBs accrued through risk reduction have not been evaluated with respect to temporal changes in business and daily life activities associated with lifeline utilities such as electricity, water, and gas.
    In this study, we conducted a questionnaire survey of city residents and non-manufacturing workers. Using the data from the questionnaire, we developed an evaluation method for improvements in resilience. In addition, we verified the effect of improving resilience through a case study of a real urban district and a housing complex district.
    The results of this research are summarized below.
    (1) Proposal of an evaluation method for resilience in the business sector
    In the questionnaire survey, we asked non-manufacturing workers about the effect on business activities of lifeline stoppages (electricity, water, and gas) and derived a “Resiliency Factor” according to the type of business. Then, we proposed a method for resilience improvements based on Resiliency Factor and a recovery curve for business activity according to the lifeline stoppage time, and we plotted a recovery curve for business activity according to the lifeline stoppage time. In addition, we expressed the resilience improvement in the business sector in monetary terms.
    (2) Proposal of an evaluation method for resilience in the housing sector
    In the questionnaire survey, we asked residents about the losses incurred as a result of electric power failure. Then, we derived a basic unit of loss due to electric power failure according to stoppage time. This basic unit was then used in an estimation model considering housing type and location to assess resilience improvements in the housing sector in monetary terms.
    (3) Case study
    We performed a case study of the effect on resilience of introducing a community energy network under the assumption of a large-scale earthquake. In the evaluation, the Tamachi Station district was taken as an example of urban areas and the Hamamidaira housing complex district was taken as an example of areas around existing housing complexes We found that by introduction of the community energy system, the Tamachi Station district would accrue NEBs of 140 million yen per year and the Hamamidaira housing complex district would accrue NEBs of 5.11 million yen per year.

  • MULTIVARIATE ANALYSIS ON PHYSICAL ACTIVITY OF STUDENTS INFLUENCED BY NEIGHBORHOOD ENVIRONMENT

    Kanoko NISHIKAWA Toshiharu IKAGA and Satoko OMI

    Journal of Environmental Engineering (Transactions of AIJ) (Architectural Institute of Japan)  82 ( 734 ) 317 - 325 2017.04

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  1348-0685

    　View Summary

    The reduced ability to exercise and the increasing prevalence of overweight and obesity in students have recently become serious health concerns. Decreased physical activity in students is cited as a factor in these problems. Governmental agencies have promoted improvement of the regional environment in order to encourage physical activity in students. However, there is insufficient quantitative verification of the regional environmental factors that affect the physical activity of students. Therefore, the purpose of this study was to clarify the relationship between the regional environment and physical activity in students, using a questionnaire survey and actual measurements of physical activity.

    A questionnaire survey was conducted for more than 300 teachers across 13 elementary schools to evaluate the satisfaction with the natural environment, the public security, the facilities for communication and the public facilities of each school district. Also, a measurement survey was conducted in the same public schools in Kawasaki city and data were obtained from 702 students aged 10-11 years old across 13 school districts. During a week of September to November 2014, the number of walking steps of each student was measured by a pedometer, HJ326F and HJA-350IT (OMRON).

    1) Impact of the regional environment on physical activity
    Using the results of a questionnaire survey and actual measurements of physical activity, we conducted the multi-level model analysis in order to clarify the impact of the regional environment on physical activity of students in taking account of individual attributes. As a result, for school regions where the satisfaction with the natural environment and the public security were high, the number of walking steps on weekdays exceeded those where the satisfaction was lower. According to the multi-level model analysis, the regional average number of steps increased by about 300 for every 1pt increase in the satisfaction score of the natural environment and the public security.

    2) Relation between satisfaction with neighborhood environments and land use
    Although we examined the relationship between the satisfaction with neighborhood environment and physical activity in students, a concrete factor which increases such satisfaction with regional environment was unclear. Therefore, we carried out a correlation analysis between the satisfaction score of neighborhood environments and the land use and the zoning of the regions. The satisfaction score of the natural environment of a region was correlated with the proportion of a forested region. We also examined the negative correlation between the satisfaction with natural environment and the proportion of a dense low storied building area.

    In conclusion, the result of this study confirmed a relationship between regional environment and physical activity in students and showed the significance value of the natural environment, the public security and the facilities for communication to encourage physical activity in students.
