Recently, health and pleasant environment are becoming increasingly significant in society due to the increased interest in qualitative improvement of social environment and dwelling environment. People today are spending more than 90% a day in indoor environment with increased indoor residence times, and environmental factors as air quality, sound environment, light environment, and thermal environment for comfortable indoor environment are being recognized as fundamental conditions for buildings. Research and laws are being established by various organizations with the emerged importance of indoor environmental management, however detailed assessment is not being conducted because there are very few evaluation items for indoor environment. Specially, realtime measurement of the elderly with weakened physiological function needs to be conducted according to the surrounding environment and residents’ behaviors because they relatively lack the ability to adapt to the changes in indoor environment compare to the general public. Therefore, the purpose of this study is to compose sensors and establish a system structure for integrated measurement and realtime monitoring of indoor environment for the elderly. The methods of this study are as follows. First, this study investigates influencing factors of indoor environment and measurement sensor by analyzing literature reviews and previous studies. Secondly, measurement sensors for the elderly are categorized by taking environmental disease factors that affect the elderly into consideration based on literature review. Thirdly, this study suggest a sensor organization system for integrated measurement of the indoor environment in home improvement of the elderly. It is judged that this study can be used to optimize environmental conditions of interior space of housing for the elderly and elderly care facilities because it is suggested a configuration system of sensors by considering environmental disease factors that affect the elderly.

Yang, Wonyoung,Moon, Hyeun Jun Elsevier 2019 Building and Environment Vol.148 No.-

<P><B>Abstract</B></P> <P>Humans perceive environments through the interaction and integration among various sensory stimuli. While research on multisensory interaction research has increased over the last few decades in the fields of cognitive neuroscience and neurophysiology, the effect of multisensory interaction on indoor environmental perception, including thermal comfort, acoustic comfort, visual comfort, and indoor environmental comfort, has not been comprehensively understood. This study investigated the influence of multisensory interaction on acoustic comfort, thermal comfort, visual comfort, and indoor environmental comfort with three physical indoor environmental factors, i.e., acoustic, thermal, and illumination conditions in an environmentally controlled laboratory. Three homogenous room temperatures (20, 25, and 30 °C) and illuminance levels were chosen (150, 500, and 1000 lx). For each of the nine configurations, four different types of sound (babble, fan, music, and water) with four sound levels (45, 55, 65, and 75 dBA) were presented for 25 s each. Sixty university students participated in all the test configurations and provided responses on their subjective comfort of discrete senses and the overall indoor environment.</P> <P>The results indicate that acoustic comfort increases at thermoneutrality, thermal comfort increases with a decrease in the noise level at 500 lx, and visual comfort increases with a decrease in the noise level at thermoneutrality. Indoor environmental comfort increases with a decrease in the noise level at thermoneutrality in brighter conditions. Although a specific physical indoor environmental factor has the greatest effect on the corresponding sensory comfort, other physical factors also affect the perception of subjective comfort. In steady-state thermal and illumination conditions with time-varying sound stimuli, the effect of acoustic factors was the greatest on indoor environmental comfort, followed by room temperature and illuminance. Thus, it can be concluded that the impact of acoustics on indoor environmental comfort was the greatest among the three environmental factors tested in this study.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The effects of multisensory interactions were investigated in steady-state thermal and luminous conditions with time-varying sound stimuli. </LI> <LI> Thermal comfort and visual comfort were affected by acoustic, thermal, and illumination conditions. </LI> <LI> Acoustic comfort was affected by acoustic and thermal conditions. </LI> <LI> All the physical factors tested in the study influenced indoor environmental comfort. </LI> <LI> Time-varying acoustic factors had a higher effect size on the overall indoor environmental comfort. </LI> <LI> Effects of gender appeared to differ in the range of each physical factor. </LI> </UL> </P>

Introduction ㅇ The objective of this study is to identify major issues and improvement directions in indoor air quality (IAQ) management by collecting detailed information and expert opinions on the current IAQ management. Ⅱ. Status of Indoor Air Quality Management in Korea 1. Legislation regarding IAQ management ㅇ Different facilities are managed under different laws according to the type of facility; most facilities are managed by the Ministry of Environment. Educational facilities (schools) are managed by the Ministry of Education, and workers’ workplaces (facility) are managed by the Ministry of Employment and Labor. - Since each individual ministry takes part in IAQ management, they all have their own standards, target pollutants, and management methods, differing from one another. 2. IAQ management policy ㅇ For the integrated management of IAQ, the Basic Plan for IAQ Management is established every five years, and the content of the IAQ management statutes and standards are decided after the Minister of Environment consults with the heads of related central administrative agencies. ㅇ In addition, the IAQ management policy is implemented through the Comprehensive Plan for Environmental Health, Comprehensive Plan for Particulate Matter Management, and Measures to Improve Air Quality in Subway Stations. - The Comprehensive Plan for Environmental Health suggests strengthening IAQ management to reinforce exposure management against environmental hazards, and proposes to raise the recommended IAQ standards in newly built houses based on human risk assessment and make public transport more enjoyable as its strategies. - In the Comprehensive Plan for Particulate Matter Management, IAQ management is included as one of the 15 key tasks, and the plan includes details such as support for improving the indoor environment of facilities used by the vulnerable populations, and expanding the range of facilities that are required to install ventilation. - The Measures to Improve Air Quality in Subway Stations present specific tasks for underground stations, tunnels, and subway vehicles, respectively. ㅇ It is necessary for different government entities to share and communicate the information on current status as well as detailed evaluation of the performance and limitations of each plan for continued cooperation. 3. Identification of major issues and policy needs □ Expert survey ㅇ We conducted a survey among experts in the field related to IAQ to evaluate the implementation status of the Fourth Comprehensive Plan for Indoor Air Quality Management by field and identify priority projects. - There were positive evaluations on air quality management in facilities used by vulnerable populations (such as daycare centers, schools, etc.) and underground stations, while residential environment improvement and the establishment of autonomous IAQ management system and indoor environment management centers received negative feedback. - A lack of management personnel was identified as one of the main factors hindering the improvement of IAQ. - Priority projects over the next one-two years included improving the indoor environment of public transportation and multi-use facilities and expanding IoT-based air quality monitoring among the projects currently underway; for new projects,, IAQ improvement in small-scale and old facilities, technology development for IoT and AI-based integrated IAQ management, increasing awareness through education and publicity, introduction of incentive system and expansion of autonomous management through supporting self-measurement equipment were included. □ Expert forum ㅇ An expert forum was held to discuss ways to improve indoor air quality, and various opinions of experts from academia and related institutions were collected. - The forum suggested that the Ministry of Environment take the lead and provide standards and guidelines for all ministries in order to solve problems caused by the fragmented responsibility for management among different ministries. - Since a relatively large amount of budget is being invested to improve indoor air quality in subways and schools, a thorough review of its efficiency should be conducted. - Institutional means are necessary to utilize diverse technologies, and plans for the step-wise implementation of the projects are also necessary. - IAQ management standards should be based on receptor risk, and it is important not only to raise the management standards, but also to prepare a system for implementing the strengthened standards. Ⅲ. Suggestions for Improving IAQ ㅇ We propose policy directions and priorities for improving IAQ based on the current status analysis and expert opinions. - A control tower for indoor air quality management should be established and standardization of indoor air quality management is needed. - Regulatory blind spots should be scrutinized and the scope of target facilities should be expanded to include facilities with a high level of exposure. ㆍ Priorities should be set in consideration of the risk reduction effect and the ease of policy implementation, and a roadmap for expanding the management target accordingly should be drawn. - The focus of IAQ management should be shifted from follow-up management such as removal of pollutants through air purification to prevention strategies that include fundamental management of pollutant removal. - Moreover, it is necessary to increase indoor air quality monitoring and inspection by securing budget and human resources. ㆍ Voluntary management of facility managers must be implemented by actively promoting the Indoor Air Quality Certification. - IAQ management standards and management policies must be based on scientific evidence. - The IAQ management system should be strengthened taking into account regional characteristics and IAQ improvement projects linked to energy efficiency should be designed. Ⅳ. Conclusion ㅇ The strategies proposed in this study to improve IAQ management can be utilized in ‘reinforcing IAQ management for comfortable breathing,’ a national task pursued by the new government. ㅇ We suggest that identifying regulatory blind spots and raising management standards based on health risks should be set as the short-term management priority, and in the long term, the management range should be expanded to include not only reducing exposure to pollutants but also temperature-humidity index, and furthermore, comfort levels. ㅇ The results of this study will contribute to building a national environmental health safety net and strengthening public safety through improvement of IAQ.

제주지역 직장어린이집 보육실의 겨울철 실내온열환경 실태

김봉애(Kim, Bong-Ae),고연숙(Ko, Youn-Suk) 대한건축학회 2017 大韓建築學會論文集 : 構造系 Vol.33 No.12

This study was conducted to investigate the thermal environment status of nursery rooms in workplace daycare centers in Jeju and propose measures to improve their indoor physical thermal environment. For this purpose, measurements were performed in the winter indoor physical environment of 51 nursery rooms in 11 workplace daycare centers and a psychological evaluation survey on the thermal environment of nursery rooms was conducted for 70 nursery teachers. The investigation was carried out over 11 days in January 2017. The results are as follow. The average indoor temperature of the nursery rooms was 21.3℃(18.7-23.8℃) and the indoor temperatures of 47 nursery rooms (92.9%) were higher than the environmental hygiene management standard for domestic school facilities (18-20℃). The average relative humidity was 33.9% (16.4-56.0%), and 37 nursery rooms (86.3%) showed a lower average relative humidity than the standard (40-70%). The average absolute humidity was 9.1g/㎥ (4.7-13.6g/㎥), which was lower than the standard for preventing influenza (10g/㎥). When the indoor temperature and humidity of the nursery rooms were compared with international standards, it was found that 85% or more of the 51 nursery rooms maintained appropriate indoor temperatures, but 40-50% of the nursery rooms maintained a low humidity condition. Therefore, they need to pay attention to maintaining the appropriate humidity of the nursery room to keep the children healthy. The average indoor temperature of the nursery rooms showed a weak negative correlation with the average relative humidity. The indoor temperature had a significant effect on the relative humidity: a higher indoor temperature resulted in lower relative humidity. Regarding the fluctuations in the average indoor temperature of the nursery rooms during the day, in daycare centers that used floor heating, the indoor temperature gradually increased form the morning to the afternoon and tended to decrease during lunch time and the morning and afternoon snack times, due to ventilation. The daycare centers that used both floor heating and ceiling-type air conditioners showed a higher indoor temperature and greater fluctuations in temperature compared to the daycare centers that used floor heating only. In the survey results, the average value of the whole body thermal sensation was 3.0 (neutral): 32 respondents (62.7%) answered, “Neutral”, Which was the largest number, followed by 21 respondents (30%) who answered, “Slightly hot” and 17 respondents (24.2%) who answered, “Slightly cold.” Twenty-nine respondents answered, “Slightly dry,” which was the largest number, followed by 28 respondents (54.9%) who answered, “Neutral” and 10 respondents (19.6%) who answered, “Dry.” The total number of respondents who answered, “Slightly dry” or “Dry” was large at 39 (56.4%), which suggests the need for indoor environment management to prevent a low-humidity environment. To summarize the above results about the thermal environment of nursery rooms, as the indoor temperature increased, the relative humidity decreased. This suggests the effect of room temperature on the indoor relative humidity; however, frequent ventilations also greatly decrease the relative humidity. Therefore, the ventilation method and the usage of air conditioning systems need to be re-examined.

신민규 ( Min Kyu Shin ),이진국 ( Jin Kook Lee ) 디자인융복합학회 2014 디자인융복합연구 Vol.13 No.4

일상의 대부분을 실내공간에서 보내고 있는 현대인들에게 실내 환경의 상태는 건강 및 작업효율성에 영향을 미치는 중요한 요소로써 작용한다. 쾌적한 실내 환경을 위하여 여러 기능을 가진 다양한 센서를 활용하여 환경상태를 파악하고 문제가 되는 요소를 찾아 개선할 수 있다. 과거에는 센서의 크기가 크고 경제성이 떨어지며 제어할 수 있는 하드웨어 및 소프트웨어의 제약이 많았으나, 최근에는 값이 저렴하고 크기가 작을 뿐만 아니라 사용자들이 제어할 수 있는 다양한 하드웨어 및 소프트웨어 환경을 지원할 수 있게 되었다. 이는 실내 공간 곳곳에 설치하여 환경데이터를 측정할 수 있도록 하는 기반을 용이하게 만들었으며, 본 논문에서는 실내 곳곳에 설치된 수많은 센서로부터 측정된 여러 데이터를 사용자의 목적에 따라 수정이 가능함과 동시에 직관이면서도 효과적으로 표현하는 방법으로써 평면도상에 실내 환경데이터를 시각화하는 통합적 구현 접근방법에 관하여 제안하고자한다. 본 논문에서 제안한 접근방법의 구현가능성과 평면도상 시각화 결과 의 효용성을 살펴보기 위하여 특정한 공간의 온도변화를 평면도상에 시각화하는 것을 목적으로 구현을 진행하였다. 구현사례를 통해 환경데이터를 평면도상에 시각화하는 것에 대한 가능성과 숫자 및 차트로만 데이터를 표현하던 방식과는 다른 평면도상에 표현된 시각화 결과를 얻을 수 있다. Indoor environment is a crucial factor which effects on people``s health simply because most people spend their most of daily life indoor. Maintaining a pleasant indoor environment is necessary in terms of people``s health and work productivity. Precisely monitored indoor environment, after understanding the condition of indoor environment by using many sensors, is one of the initial dataset in order to keep indoor environment comfortable. Conventional sensors are comparatively expensive and their control methods are limited. Recently, however, sensors become affordable and controllable by using several user-friendly interfaced hardware and software. This enables us to measure and maintain the indoor environmental data. This paper aims to develop and propose an approach for visualizing the indoor sensor data on the floor plans as a method to effectivelyrepresent sensor data. To find out the feasibility of proposed approach, we implement proposed approach using several software and hardware modules in an integrated manner. As a result, we can visualize the sensor data more intuitive and readable.

<P>The purpose of this study is to suggest a direction by which to develop environment-friendly school facilities. To achieve this, field measurements were conducted to evaluate indoor environmental conditions such as thermal, visual and indoor air quality in 15 schools. Additionally, environmental elements were also investigated and analyzed through teachers' questionnaires. According to the results of measurements, the thermal condition, minimum illuminance, CO, TBC and formaldehyde were satisfactory in most of the classrooms. However, CO<SUB>2</SUB>, PM<SUB>10</SUB> and TVOCs exceeded the standards. As it was found that the indoor classroom environment significantly influences the academic achievement of students, a plan should be made for indoor noise isolation, comfortable thermal environment maintenance, and uniform light distribution. The environment-friendly architectural design elements applicable to school facilities were found to be: environmental studio, vegetable gardening, school forest, and landscape architecture elements, in this order.</P>

There has recently become one of the major concern expressed the general public and regulation agencies concerning health risks associated with indoor air pollution in Korea. A new indoor air quality program under ""Legislation of Indoor Air Quality Management for Public Facilities"" is enforced to act on the end of May, 2004 by the Korea Ministry of Environment. The purposes of this article were to discuss the sustainable development of indoor air pollution and to strengthen the importance of the sustainability of indoor air quality. Sustainable development is development that meets the needs of the present without compromising the ability future generations to meet their own needs and a new theory that grew out of the conservation / environmental movement of the 1970"s. While the conservation/environmental movement asked questions about preserving the Earth"s resources, sustainable development includes questions about how human decisions affect the Earth"s environment. Sustainable development of environmental pollution has been discussed over the last 20 year in most countries, but an important health problems of indoor air pollution became a social issues in recent years. We must develop global perspectives and maintain effective balance between available resources and human needs. The further understanding of the sustainable development of indoor air pollution is extremely useful in defining the components of healthful indoor air in major indoor environments. Additional information concerning more detailed housing characteristics, daily activity patterns, and seasonal factors which may influence indoor pollutants should provide important information on sustainable development in indoor air pollution.
