본 연구는 대표적인 미세먼지와 실내유해물질인 질소산화물의 저감을 위해 이산화티탄 광촉매를 환기장치에 적용한 것으로 그 내용은 다음과 같다. 기존 연구는 실내에 자외선 적용의 한계로 인해 주로 건축자재에 광촉매 혼입을 통해 실외 자재를 대상으로 진행되었다. 자외선 실내 적용 한계를 극복하고자 기존 선행연구를 통해 확인된 이산화티탄 광촉매의 오염물질 분해 효과를 실내에 적용이 가능하도록 자외선램프의 설치가 가능한 반응장치를 설계 및 제작하였다. 해당 반응장치를 실내 환기장치에 적용하여 Mock-Up에 적용하였다. Mock-Up 실험은 그 체적을 시간당 1회, 5회 환기하는 풍량을 변화시켜 NOx 저감 성능을 확인하였다. 그 결과, 환기 풍량이 증가함에 따라 NOx 저감시간이 비례하여 감소되어 그 성능이 증가하는 것을 확인하였다. 해당 연구를 통해 오염물질 저감 효과를 가진 이산화티탄 광촉매의 실내 활용 방안과 그 성능을 확인할 수 있는 기초적인 연구 결과를 도출하였다.

This study examined the particulate removal performance of three different types of air filters inside a heat exchanger. Of interest was the ability of each filter type in reducing the transmission of outdoor particulate matter of PM10 from entering an apartment while the heat exchanger was in operation. The study tested one commonly used medium filter (E11 grade) and two HEPA filters (H13 grade) of different thicknesses. Two different concentrations of particulate matter were used in the experiment to address different ambient air quality conditions in Korea, 32.75 ㎍/㎥ and 67.26 ㎍/㎥. Study results indicated that under the particulate matter concentration of 32.75 ㎍/㎥, all three filters were capable of removing more than 95% of the fine dust. However at a particulate matter concentration of 67.26 ㎍/㎥, the medium E11 grade filter was only able to remove about 90% of the particulates whereas the HEPA H13 grade filters were able to remove 95% or more of the particulates. The thicker HEPA filter (40T) was also more effective in removing particulates than the thinner HEPA filter (20T) by about 1.6 to 3 percentage points. Based on the findings of this study, it is recommended that HEPA filters of 20T thickness or greater be used during the high air pollution seasons of winter and spring in Korea while medium filters can be used during the other seasons to reduce outdoor air pollution transmission indoors.

The purpose of this study is to investigate energy used during building operation and maintenance phase for TCA. The final goal of this research is to calculate the amount of the most frequently used energy based on the researched data. The analysis is based on statistical data and researched the most frequently used energy source and types of apartment. To achieve this, statistical data from National Statistical office is used and calculated monthly used energy based on the amount of energy used in the apartment. As a result, the use of energy was different even in the similar size of apartment because of the difference of heating system and deterioration of facility. However, monthly use of energy was shown to have certain ratio regardless of size of apartment.

This study was conducted to investigate and possibly prevent airborne infection in general hospitals The CFD analysis of emergency and outpatient departments was summarized as follows; First, assessment on the first floor of the general hospital revealed that indoor exhaust air was not ejected in concurrence with the supply air, which could lead to an air shutdown. Second, CFD analysis confirmed the results of the actual survey that air congestion and inflow into other spaces may increase the probability of airborne infection. Third, the CFD analysis reflecting the improvement plan established that when the exhaust in the lobby was increased and the door was opened, there was difficulty in air control. When all the doors were closed, pressure differences occurred on the left and right sides of the lobby. Particularly, air flow may be stagnant in the stairwells and corridors, or an introduction of air in the lobby. Further installation of the front rooms, doors and exhaust outlets also enhanced the control of air flow between spaces, and flow through staircases and elevators. Therefore, it is thought that the separation of space and the proper location of exhaust could be the most effective way of controlling airflow in hospitals. In addition, it is necessary to put in place measures to reduce the possibility of airborne infection by applying each of the exhaust systems by space.

Recently, high-rise apartment is being briskly built but there has problems such as lack of ventilation, stack effect and energy consumption. Therefore Small Wind Power System combined exhaust as measures to solve these problem. The purpose of this study is increase the effect of small wind power systems with exhaust apply for inflow module to solve these problem. For this, through CFD simulations are use to evaluate inflow module. Results from the study can be summarized as follows; the inflow module can increase exhaust air speed and generation. So inflow module is better than normal exhaust pipe.

In recent years, many studies have been conducted on smart low carbon cities through the fusion of ICT information technology for the purpose of reducing carbon. In this study, we investigated 13 cities in three continents that implement low-carbon city policies and analyzed the size, economic and social characteristics of each city to identify the degree of dynamic mechanism for carbon reduction. To this end, we quantified the elements of the city and analyzed the basic requirements for low-carbon cities using the TOPSIS method. The study found that most cities were better able to activate institutions and cultural conditions, facilities and functional conditions, and economic and industrial conditions than other engines, and these three were the main forms of power for smart low carbon cities. The results of this study are expected to be used as a basis for suggesting policy recommendations and improvement measures for future smart low carbon cities.
