This study is related with the energy saving of factory buildings, and automotive factory building are targeted for the study. Thus, energy saving strategies of factory buildings have been derived, being focused on automotive factory building, and then the energy saving factors that can be applied to the target factory buildings, have been selected. And then the energy consumption of heating, cooling and lighting, and total energy consumption have been calculated. Through this, the optimal combination by energy, has been derived and each integrated saving model has been proposed.

The current world wide interest in environmental issues has moved from energy conservation to $CO_2$emission reduction. Recently, according to the increase in demand for water resources, insufficient potable water circumstance is supposed, unless there are corresponding in crease in water conservation and water recycling. This study has attempted to analyze $CO_2$emission reduction by water saving strategies like installation water saving devices, rain water harvesting and grey water system. To do this, this research investigates applicable water conservative strategies by literature review and calculated total water saving. The results show that (1) firstly, the water usage and $CO_2$ emission could be reduced up to 44%, (2) $CO_2$ emission reduction by water saving devices and rainwater harvesting system is about 47.7%, and (3) water usage and $CO_2$ emission reduction by grey water system is about 66%. In the future, this paper will be utilized for water management from the early design stage to maintenance stage of water glutton building.

This study aims to present the fundamental strategies to improve the Indoor Air Quality (IAQ) in apartment buildings. To investigate the concentration of indoor air pollutants such as radon, formaldehyde, and VOCs, both the document survey and the field measurement were conducted. In addition, to identify the source of the air pollutants, the laboratory experiment was carried out for various building materials. Finally, the minimum period to be reserved befor3e building occupation to ensure healthy IAQ, which largely depends on the ventilation rates, was simulated using a simple compuer program. The results of this study can be summarized as follows: 1. In case of newly-constructed apartment houses, concentrations of formaldehyde, VOCs and radon were found to exceed the standard. Meanwhile, at existing apartment houses, concentrations of VOCs, particularly toluene and xylene, highly exceeded the standasrd level. Concentrations of formaldehyde and radon, however, had been lowered according to the duration of occupation. 2. The laboratory experiment of concentration of pollutants per square meter of building material surface area showed that radon gas was much emitted from the gypsumboard; formaldehyde from flooring and wallpaper; and VOCs from paints and kitchen furnishings. The emission rates of formaldehyde and VOCs were proportional to air temperature. 3. According to the simulation of the minimum period to be reserved before occupation, newly-constructed airtight houses required about 190-200 days, and naturally ventialted houses with fully-open-windows required about 20-45days, in order to keep the level of radon gas lower than standard. Therefore, with the current practice, the date of occupation should be delayed for about 15 days.

A large portion of the energy cost of a building is cooling and heating to maintain a comfortable indoor environment. Air conditioning is now one of the important parts in the building design, as increase in energy consumption and pollutant emission in energy conversion process. In this study, elements that affects the energy consumption of model building are identified and the perfomance analysis of the alternative a Low Energy Cooling Systems considering characteristics of model building and energy saving performance is analyzed. As a result, applied to earn and suggest basic data for energy saving measures. In this study, EnergyPlus simulation program was used to evaluate the energy load when alternative Low Energy Cooling Systems are applied to the model building. The reliability of simulation program is verified by comparing actual energy load from operation data of building management office and predicted energy load using simulation program. Verification of Low Energy Cooling Systems is highly required due to increase in CO₂ emission and energy cost of cooling energy. There are several types of Low Energy Cooling Systems nowadays, but those systems are rarely applied due to lack of energy saving performance verification and its high initial cost.

As buildings have a significant impact on Global Warming and Climate Change, we need to reduce the carbon footprint of commercial and residential buildings. This can be done by creating 'Zero Emission Building'. Zero Emission Building means that, the net carbon emissions from energy use in the building would be zero. This cannot be achieved by good low-energy design alone. Building energy demand has also to be met renewable energy supply. Therefore, this study aims to provide the foundational data for design process for 'Zero Emission Building'. For this propose, Technical Factors of Zero Emission Buildings were analyzed through the case study.

The cooling load of the top floor of a building will increase greatly due to the excessive solar radiation on the roof compared to other floors. The study selected solar reflectance, thermal emittance and insulation thickness as the thermal performance factors of the roof affecting the energy efficiency of the top floor of the building and conducted the sensitivity analysis. The result showed that the most significant thermal performance factors of the roof affecting the cooling load of the building were in the order of solar reflectance, thermal emittance, and insulation thickness. For solar reflectance and thermal emittance, the cooling load varied as the variables changed. For insulation thickness, however, the cooling load was not affected if the thickness was more than 150㎜. In addition, the result of the sensitivity analysis on the thermal performance factors of the roof affecting the heating load showed that the significant factors were in the order of insulation thickness, thermal emittance, and solar reflectance. For the heating load of the top floor of the building, it showed that the value changed depending on the thickness of insulation and its effect on the heating load decreased before if the thickness was more than 210㎜.
