The purpose of this paper is searching for the reduction way of carbon tax in the life cycle of apartment building through the estimation on the carbon tax influence of the construction cost and the running energy cost in the apartment building. The Green House Gases(GHG) emission level of South Korea was 10th in the world at 2004. Therefore, Korea may should be into Annex-Ⅰlevel of UNFCCC at 2013 and Korean government has been prepared the regular of carbon tax that aim to GHG reduction. The reduction of GHG in the building industry is a task of great significance because the building industry has been consumed 30∼40% energy of all energy consumption. This paper used the unit CO2 emission data of the construction materials, the construction works, the running energies as well as the unit cost of the construction materials, the construction works, the running energies in the apartment building. In conclusion, if carbon tax will be levied 10,000~150,000(won/CO2Ton) in the korea, the construction cost will rise up 1.03~15.45%, the running energy cost will rise up 2.95~44.26%, and the life cycle cost will rise up 2.10~31.43% in 60 years building life cycle. The carbon tax of construction phase is unavoidable tax because all of the construction materials is necessary in the building, but the reduction of running energy carbon tax is passible because running energy conservation is passible. Therefore, the reduction ways of carbon tax in the life cycle of apartment building were the conservation of running energy and the change to the renewable energy system.

For the building energy conservation, the energy authorities recommended that the manager of building should keep the indoor temperature below $18^{\circ}C$ in the public spaces, in the large scale building during heating season. The occupants in the spaces don't feel the thermal comfort because Predicted mean vote(PMV) of the spaces temperature below $18^{\circ}C$ is approximately -1.0(slightly cool). Recently, the companies of wears supply the rechargeable heating insole with the lithium ion battery to the people in the cold environment. This research aim is to present of thermal responses when the occupant wearing the rechargeable heating insole in the spaces temperature below $18^{\circ}C$ through it experiment on the thermal responses of subjects wearing rechargeable heating insole as well as it evaluate on the variation of thermal responses of subjects in the climate chamber. The variations were Thermal sensation vote(TSV) with ASHRAE 7 and 11 scales, Mean skin temperature(MST) with ISO 9886-2004, Sole skin temperature(SST) of the subjects as well as PMV of environmental chamber. The research presents that TSV-7scale, TSV-11scale, MST of the subjects wearing heating insole were not increasing during the experiments. As contrast this, SST of the subjects were $1.6^{\circ}C$ higher than the subjects not wearing heating insole. In conclusion, the rechargeable heating insole with the lithium ion battery influence the SST increasing but it can't influence the whole body thermal response at the $18^{\circ}C$ environment.

The body temperature after walking in a cold environment may appear lower than when it is measured under stable indoor conditions. In order to improve the accuracy of detecting abnormal body temperature for COVID-19 pandemic situation, it is important to measure the accurate body temperature of subjects who enter the buildings. To do this, the body temperatures of 19 subjects were measured and analyzed immediately after walking for 15 minutes in a cold environment (7℃) and at rest in a climate chamber (20 ℃) for 15 minutes. As a result of measuring the subject's eardrum temperature with an eardrum thermometer, it was found that 36.3℃ (S.D. 0.50℃) immediately after walking in a cold environment, 36.8℃ (S.D. 0.42℃) after stabilization, and a difference of 0.5℃. As a result of measuring the subject's forehead temperature with non-contact infrared thermometers A, B, and C, immediately after walking in a cold environment, they were 36.3℃ (S.D. 0.27℃), 36.3℃ (S.D. 0.27℃), and 36.2℃ (S.D. 0.33℃), respectively, and after resting, 36.7℃, (S.D. 0.27℃), 36.6℃ (S.D. 0.20℃), 36.8℃ (S.D. 0.41℃), respectively, the difference was 0.4℃. As a result of measuring the subject's forehead skin temperature with a contact skin thermometer, it was found to be 31.0℃ (S.D. 1.57℃) immediately after walking in a cold environment, 33.2℃ (S.D. 1.43℃) after stabilization, and a difference of 2.2℃. The difference between the forehead contact skin temperature and the eardrum temperature was 5.3℃ immediately after walking in a cold environment and 3.6℃ after stabilization. In conclusion, it is thought that some correction is necessary when discriminating abnormal body temperature with a non-contact infrared thermometer in winter. 추운 환경에서 보행 후 입실한 인체의 체온은 실내 안정 시보다 낮게 나타날 수 있다. 이 연구는 COVID-19 이상체온 판별의 정확성을 높이는데 기여하고자, 피험자 19명을 대상으로 추운 환경(7℃)에서 15분 보행 직후와 15분 기후 챔버(20℃) 내 안정 시 체온을 측정, 분석하였다. 고막 온도계로 피험자의 고막온도를 측정한 결과, 추운 환경 보행 직후에 36.3℃(SD 0.50), 안정 후에 36.8℃(SD 0.42), 차이 0.5℃로 나타났다. 비접촉식 적외선 온도계 A, B, C로 피험자 이마의 체온을 측정한 결과, 추운 환경 보행 직후 각각 36.3℃(SD 0.27), 36.3℃(SD 0.27), 36.2℃(SD 0.33)로, 안정 후에 각각 36.7℃(SD 0.27), 36.6℃(SD 0.20), 36.8℃(SD 0.41)로, 차이가 0.4℃로 나타났다. 접촉 피부온도계로 피험자의 이마 피부온도를 측정한 결과, 추운 환경 보행 직후에 31.0℃(SD 1.57)로, 안정 후에 33.2℃(SD 1.43)로, 차이는 2.2℃로 나타났다. 이마의 접촉 피부온도와 고막 온도의 차이는 추운 환경 보행 직후 5.3℃, 안정 후에 3.6℃로 나타났다. 결론적으로, 겨울철 비접촉식 적외선 온도계로 이상체온을 판별할 때에는 약간의 보정이 필요하다고 생각된다.

고정하중 및 공사비 경감과 관련하여 체육관 등의 큰 공간에 경량 철골 및 금속재 지붕재료가 사용되고 있다. 이러한 금속 지붕은 매끄러운 표면에 의하여 햇빛 경면반사를 일으키고 이에 의하여 인근지역에 불능현휘를 야기 시킨다. 이러한 현상은 인근 건물에 과열, 눈 건강 위해, 열적 불쾌적, 냉방부하 증가와 같은 환경적 문제를 발생시킨다. 본 연구는 이러한 금속 지붕의 햇빛 경면반사를 감소시키기 위하여 여러 가지 도장 샘플을 제작한 다음 각각의 햇빛 반사 휘도를 측정하고 가장 효과적인 감소방법을 찾고자 한다. 본 연구에서 9개의 샘플 가운데 7개의 샘플은 불능현휘를 발생시킬 수 있는 수준의 경면반사 휘도가 나타났다. 반면 규사를 혼합하여 표면을 매우 거칠게 구성한 2개의 샘플에서 확산반사가 발생됨에 따라 확연히 경면반사를 감소시킬 수 있었다. A lightweight building envelope, such as metal roofing, is widely used to reduce the dead load and cost of construction when designing gymnasiums and other large buildings. The specular reflection of sunlight from a gymnasium roof with a highly reflective metal material can result in disability glare. The reflective phenomenon generates environmental problems, such as the overheating of the building materials, vision problems, discomfort in thermal environment and the increase of cooling load in the neighborhood. The aim of this research is to reduce the specular reflection of sunlight from a metal roof using a rough coating, such as paint mixed with silica sand. The brightness of the sun’s reflection on a metal roof of model gymnasium was investigated. The research was carried out by using 9 samples of coating material and measuring the level of brightness of the reflected sunlight under natural sunshine condition. As the result, the disability glare occurred on 7 samples without rough surface and the diffusing reflection occurred on 2 sample surfaces with rough silica mixed coating.
