최근 새집증후군과 관련하여 건설업체들의 움직임이 상당히 빨라지고 있다. 금년 5월부터 공동주택의 실내공기질 법규가 강화되어 발효되는 것에 발맞추어 신규 분양되는 아파트를 대상으로 그동안 개발되어 온 친환경 기술을 모두 적용하여 예상되는 법규의 가이드라인보다 강화된 선진국 수준의 청정한 실내공기환경 조성에 최선의 노력을 다하고 있다. 이것은 최근 관심이 고조되고 있는 "well-being"바람에 편승하여 소비자들의 많은 호응을 얻을 것으로 보인다. 즉 아파트 공기질과 관련한 사회적 수요조건이 창출되었다고 판단된다.

Purpose: Indoor air quality (IAQ) in the radiation treatment center which is generally located underground is important to the health of hospital workers and patients treated over a long period of time. this study was conducted to measure and analyze the factors related to IAQ and subjective symptoms of sick building syndrome, and to establish the causes influencing IAQ and find a solution to the problems. Methods and Materials : Self administrated questionnaire was conducted to check the workers' symptoms and understanding of the work environment. Based on a preliminary investigation, the factors related to IAQ such as temperature, humidity, fine particulate. carbon dioxide, carbon monoxide, formaldehyde, total volatile organic compounds (TVOC), and radon gas were selected and measured for a certain period of time in specific sites where hospital workers stay long in a day. And we also evaluated the surrounding environment and the efficiency of the ventilating system simultaneously, and measured the same factors at the first floor (outdoor) to compare with outdoor all quality, All collected data were assessed by the recommended standard for IAQ of the domestic and international environmental organizations. Results: Hospital workers were discontented with foul odors, humidity and particulate. They complained symptoms related to musculo-skeletal system, neurologic system, and mucosal-irritatation. Most of the factors were not greater than the recommended standard, but the level of TVOC was third or fourth times as much as the measuring level of some offices in the United States. The frequency and the amount of the ventilating system were adequate, however, the problem arising in the position of outdoor-air inlets and indoor-air outlets involved a risk of the indraft of contaminated air. A careful attention was a requirement in handling and keeping chemical substances including a developing solution which has a risk of TVOC emissions, and repositioning the ventilating system was needed to solve the contaminated-air circulation immediately Conclusion We verified that some IAQ-related factors and inadequate ventilating system could cause subjective symptoms in hospital workers. The evaluation of IAQ was surely needed to improve the underground working environments for hospital workers and patients. On the basis of these data, from now on, we should actively engage in designs of the department of radiation oncology or improvement in environments of the existing facilities.

Thermal comfort provide satisfaction of thermal environment and affects productivity of occupants in residential building. However, temperature control can not provide the thermal comfort at all the time. because thermal comfort is influenced by many environmental variables such as temperature, relative humidity, air velocity, radiation temperature, activity level and clothing insulation. The purpose of this study is that predicted mean vote(PMV) index is used as control. And, Thermal comfort is evaluated both PMV control and temperature control by simulation. Each other cases were compared, in which set-point temperatures of $22^{\circ}C$ and $24^{\circ}C$ and, set-point PMV index through the respective heating season in the simulation. The results show that PMV control is better to maintain comfort state and save energy than temperature control.

최근 환경에 대한 관심이 지속적으로 증가함에 따라 실내 공기질에 대한 관심 역시 증폭되었다. 이에 따라 실내 공기질을 결정 짓고 흡연에 이어 폐암 사망률이 높은 라돈에 대한 관심 역시 증가하였다. 따라서 본 연구에서는 실내 라돈가스의 농도를 낮추기 위한 방법을 찾기 위해 RADON EYE RD200을 이용하여 교육연구시설에서의 세 강의동을 대상으로 라돈 방출량을 측정하고, 환기를 통해 라돈의 감소량을 측정한다. 세 강의동 모두 현재 기준치인 148 Bq/m³을 초과하는 수치를 기록하였고, 강의실을 10분간 환기한 결과 1회 환기 시 평균 77 Bq/m³만큼 감소하였고, 2회 환기 시 평균 56 Bq/m³만큼 감소하였다. 본 연구를 통해 라돈의 실태 및 위험성을 인지하고 라돈에 관련된 시설물 지침 및 환기를 강조하는 방안에 대한 마련이 필요하다고 판단된다.

급속한 도시화와 인구 과밀화에 인한 교통 문제를 해결하기 위해 건설된 지하철과 부대시설은 일반시민들의 생활형태를 변화시키고 있으며 그에 따른 실내환경 문제로 야기 시키고 있다. 그리고 지하 공간의 증가와 함께 일반 시민들의 지하 공간에서의 생활시간이 길어지고 있으며 지하 공간 내의 공기질 악화도 가속화되고 있다. 미세먼지와 더불어 지하공간의 공기를 악화시키는 원인중 하나인 휘발성 유기화합물질(Volatile Organic Com pounds)은 인체에의 유해성 측면에서 중요시 되고 있다.(중략)

Along with the increase in the standard of living, the interest and awareness level of the public about environmental issues have also gradually increased. Recently, time spent on indoor activities have increased and the need for awareness and demand on methods in improving the quality of an indoor environment has been recognized. The purpose of this study is to sense the environment information through real-time monitoring of the room environment by using the IoT based technology and to maintain and improve the indoor environment to an appropriate level through the developed interlocking controller device. This provides an automatic control system in improving the indoor environment at home and other small areas like general offices in place of the traditional passive interior environmental improvement actions or large-scale facility control system. A status analysis with the relative reference values of the air quality and CO2, temperature and humidity and illumination and noise was applied through transmitting a control signal to automatic control module in accordance with the nine indoor environment standards set to improve the indoor environment.
