The former studies for expanding a balcony space were tend to be focused on only quantitative aspects. In this study, the characteristics of balcony space on thermal environment in apartment house were analysed. First, the effect of the balcony space on thermal environment of living space was analysed by field measurement. Second, the temperature distribution of the bedroom and heating/cooling load with the balcony expansion were analysed by numeric at simulation.

The purpose of this study was to investigate the present conditions of thermal environment in small-size apartments. The research methods used were measuring of environmental elements and personal self-administration for the residents' thermal comfort responses. The house subjected were 25 peung apartments facing southeast and southwest directions. The results of this study were summarized as follow ; The indoor temperature and humidity of houses subjected were 25.0∼27.3℃, 37.1∼42.5%. Compared with the distribution of indoor temperature and globe temperature of houses subjected, those of southeast house were more stable. And in the residents' thermal sensation responses, the residents of southeast houses checked more often neutral zone. Therefore the thermal environment of southeast houses were more comfortable condition than southwest houses.

These days global warming is the most important problem and the most important factor is high emission of carbon dioxide. The 23% of carbon dioxide emission for building construction must be reduced. Thermal conductivity is the most basic factor that can decrease the energy consumption especially insulation. Therefore, an accurate and continuous thermal conductivity measurement can be a way to save energy. In this paper, there are methods about how to investigate thermal conductivity measurements and comparing two methods which are the Heat Flow Meter 436 and TCi.

This study aims to analyzed thermal comfort characteristics and subject response for thermal environment of Korean traditional houses.. The air temperature and humidity in the living area of the residence were measured in during a day. And the subject response were surveyed to evaluate of controling the thermal environment factor (temperature, humidity, comfort) of the korean traditional houses. As a result, the variation of air temperature and humidity of most rooms are considerably static while condition of outdoors are much varied, it is showed that indoor climate has been controled with traditional soiled walls. And environmental control for the air temperature and humidity is estimated considerably satisfactory.

The purpose of this study was to investigate the heating regulation systems and the thermal environment of the Co-Generation apartment house in winter. Personal self-administration and interview method were used in the survey of this study. The respondents were 352 housewives who resided in Mokdong apartement using Co-Generation heating systems. Data was analyzed using SPSS PC+ computer package. The results of this study were summarised as follow; The typical patterns of heating regulation systems were intermittent and partial heating in the living room and bedroom exclusive of kitchen area. The present condition of the thermal environment were relatively warm in winter and Heatng regulation systems were influenced by type of location. Determinants of the thermal sensation and thermal comfort were the type of location of apartment as a architectural factor, clo as a personal factor.

This study deals with an evaluation method for testing the robustness of the 4 kW commercial power electronic cooling system to the thermal environment. The power electronic cooling system consists of a cascaded push-pull DC / DC converter, a three-phase DC / AC inverter, and an electric compressor. The system manufactured by the thermal environment evaluation test (heat distribution test, thermal impact test, high temperature operation test, temperature cycle test, low temperature operation test) for the commercial electric power cooling system for commercial vehicle proves that it is robust against thermal environment.

The purpose of this study is to analyse the effects of air conditioned room controlled by PMV(Predicted Mean Vote)for energy consumption and human comfort in office building. The 'EnergyPlus' was used for the evaluation of indoor thermal environment and energy consumption by the controls of room temperature and PMV. The result indicates that the PMV control could prove more profitable method for improvement of indoor thermal environment and energy conservation. Consequently, PMV control has a distinct advantage over most other control methods. An additional study is required to establish the various thermal comfort control for rooms on the basis of this work.

In metal cutting, the machining accuracy is more affected by thermal errors than by geometric errors. This paper models of the thermal errors for error analysis and develops on-the-machine measurement system by which the volumetric error are measured and compensated. The thermal error is modeled by means of angularity errors of a column and thermal drift error of the spindle unit which are measured by the touch probe unit with a star type styluses, a designed spherical ball artifact, and five gap sensors. In order to analyze the thermal characteristics under several operating conditions, experiments performed with the touch probe unit and five gap sensors on the vertical and horizontal machining centers.

Thermal comfort in the Rotunda which is high wide visiting space of the new national museum of Korea has been numerically investigated in this paper. To evaluate thor-mal comfort of the Rotunda, well-known indices, PMV and PPD were introduced. The results of present investigation show that thermal comfort is satisfied at the breathing zone of the visiting space. However a thermal stratification with $9^{\circ}C$ of temperature difference occurs along the height of the Rotunda which makes the thermal environment worse. For example, the PPD value reaches up to 50% in the 6th floor connection passage. Consequently, additional HVAC design factors should be considered in order to reduce the large thermal stratification.

본 연구는 시민들이 직접 체감하는 더위인 체감더위를 열환경 단위로 설정하여 공간적 요인과의 상관관계를 분석하고 체감더위 예측 모형을 개발하였다. 체감더위를 수집하기 위해 리빙랩이라는 시민 참여형 연구방법론을 적용하여 시민들이 직접 체감더위를 기록하고 주변의 온도를 측정하도록 하였다. 수집한 체감더위 정보의 입력지점에 기반하여 주변 도시공간적 요소를 수집하여 통계 분석을 위한 데이터셋을 구축하였다. 구축한 데이터를 활용하여 로지스틱 회귀분석을 수행하였다. 분석 결과, 기온은 주변 공간환경에 영향을 받으며, 건물 높이, 녹지율, 도로율과 음의 상관관계를 가지고, 기온과 천공률과 양의 상관관계를 가진다고 분석되었다. 또한 도로율, 천공률, 녹지율 순으로 체감더위에 강한 영향을 미치는 것으로 나타났다. 본 연구의 결과는 기후변화 대응을 위한 국지적인 열환경 대책을 마련하기 위한 열환경 평가의 기초자료로 활용될 수 있을 것으로 기대된다.
