The purpose of this study was to analyze the convenience, dearness and effectiveness of the rating system of the GB. This Green Building uses a rating system which includes a network-diagram; Sorensen-network as well as a Sequence-diagram. This study is consisted of a visualized work sheets that were divided into network-diagram, annual energy consumption, air pollution as well as LCC. It has technique of separated rating for the three departments that of the globe environment conservation, health and convenience, construction ability, as well as highest mark such as the object building's performance was which is not considered with non environmental damage level. This program aimed at establishing a weight given to input to default value and needs constant study for this program. Also this study established a inventory database for estimating air pollution quantity.

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 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.

The GHG(Green House Gases) emitted by the building energy consumption was a serious problem to the global warming because the building energy consumption ratio was approximately 30∼40% to the all energy consumption. Recently, a lot of the building energy source Heat Pump installed for the air conditioning, the domestic water supply. Generally, the Heat Pump is classified the EHP(Electric Air-sourced Heat Pump), the GHP(Gas Engine Driven Air-sourced Heat Pump), the GSHP(Electric Ground-Sourced Heat Pump). As known, the reducing performance of GHG of GSHP is approximately 20∼ 25% higher than EHP and GHP. However, the published quantitative study on the performance of reducing annual GHG was rare case. Therefore, the purpose of this study is comparison of the GHG on EHP, GHP, GSHP based on conversion data of annual energy consumption of GSHP in the case building. According to this study, the GSHP GHG emission is 18.1% lower than EHP, 8.1% lower than GHP. (In this study, the fossil fuel GHG emission estimate due to the IPCC GHG estimation rule as well as the electric power GHG emission estimate due to the electric power production ratio of fuels, the efficiencies of power plant of fuels, the efficiency of electric power distribution in Korea. The case building is a child-care center of which all area is 2,119.2㎡ and GSHP capacity is 90RT and the location is Seoul Korea.)

Recently, the company developed the cooling vest with forced fan(CVFF) for the reduction of heat stress of the worker who working in the hot climate. This CVFF made by the fabric of poly propylene that non reflection material, and it used by the micro air forcing fans and the batteries for there fans. The cooling fan made air movement between human body skin and the cloth, as a result of it made effect of down on skin temperature. But, the cooling effect of CVFF with non reflection material were insufficiency in the outdoor environment because the vest absorb the solar radiation in the day time. This study propose which the reflection material of the aluminum film coat on the CVFF. And this study experiment to the cooling effect of reflection material coating in the CVFF through the temperature measure to the two subjects who the one is the reflection material and the other one is the non reflection material in the outdoor place in hot and humid region(Summer time in the korea). In conclusion, the outside surface temperature of the reflection material coating CVFF was 4.31℃ lower than non reflection material, and the body skin temperature of the subject dressed with the reflection material coating CVFF was approximately 2.01℃ lower than non reflection material. The each subjects evaluated average thermal comfort during the experiment through the ASHRAE 7scale that reflection subject is 1.3 and non reflection subject is 1.9.

The purpose of this research was seek to an objective rating in terms of performances for an energy consumption as well as an air pollution in the green building. The existing standards through ; BREEAM, LEED, Korean government's rule, CASBEE, GBTool. All emphasize performances of an operation in terms of consumption an air pollution, but there standards are given 17~20% weight for it categories. However, these standards have so many different rating results, because there are so many different rating regulations for each other. This research used an estimating program that was made up of the modified Expanded Degree Day Method, Equivalent Rated Full Load Hours Method, and the IPCC's GHG estimation method. And this research analyzed an compare regression curves to a GHG factor of 6 in the model building. According to the this research, the objective rating regulation was based on a quantity of an energy load the GHG pollution as well as the proportional marking system.

The purpose of this study was to suggest ways on reducing the cooling and heating energy cost of the officetel building with the multiple glazing windows according to Life Cycle Costing. This study consisted of an hour-by hour energy simulation program and further data from the EnergyPlus V1-2-2 to the four pane type windows that were applied with 2 low-e polyester film and krypton gas to the officetel model building. It was determined that the four panes type windows that had 2 low-e polyester film and krypton gas applied to, them showed a cooling and heating cost reduction over traditional double glazed windows that were filled with air. According to this study, as well as the information from chart 4.5 and the LCC it was determined that the present value of the four panes of windows that had 2 low-e polyester film and krypton gas applied to them showed. a 11.4% reduction in heating and cooling in comparison to the traditional double glazed windows that were filled with air.
