Since particulate matter(PM) is generated from various emission sources when the city is operated, it is necessary to understand the characteristics of PM according to the emission source in order to establish a countermeasure. Therefore, in this study, the total amount of PM generated when the district-level city is operated was predicted for each emission source, and seasonal characteristics were analyzed. In addition, the generation of condensable PM, as well as filterable PM among the total PM, was predicted. As a result, the average percentage of area pollution in the three districts was 43.1% of the total, and the line pollution was analyzed as high as 43.7%. As a seasonal feature, it was analyzed that all pollutants generated more PM in winter than in summer. In particular, the amount of PM in winter generated from building sources was 5.1 times higher than in summer, which was most affected by seasonality among various emission sources.

The construction industry consumes lots of energy and its influence of environment is much worse than others. There were many studies before but not in building equipment field. However, the consumption of energy and the environmental load are important not only construction part but also building equipment field. We need to have the analysis which compared through the case building as well. We analyzed LCI (Life Cycle Inventory) and LCIA (Life Cycle Impact Assessment) with comparing ice thelma I storage system and direct-fired absorption chiller-heater system in the stage of manufacture and use (except construction and disposal). This study shows you the ice thermal storage system's LCI emission is 10.5% lower than direct-fired absorption chiller-heater system's and the ice thermal storage system's LCIA is 15.7% lower than direct-fired absorption chiller-heater system. It means ice thermal storage system is more environment-friendly than direct-fired absorption chiller-heater system.

Recently, due to environmental concerns and the mandatory installation of renewable energy systems, installation cases of the photovoltaic system are increasing. As renewable energy systems increase, there are many research reports and researches on the installation status of photovoltaic facilities in Korea. However, most researches are based on the total amount of renewable energy produced nationwide. Therefore, the number and system capacity were investigated and analyzed in order to understand the current status of photovoltaic facilities for business in each administrative district in Korea. In this study, data related to photovoltaic facilities by the administrative district in Korea were collected through open information portal(open.go.kr). The scope of data collection was for business facilities corresponding to power generation projects among electricity businesses and was for plants from the past to 2019. Based on the collected data, the number of photovoltaic facilities by region, system capacity, capacity per population, and capacity per area of the administrative district were analyzed. Korea"s photovoltaic facilities have surged since 2017, and about 70.9% of the total installed system cumulative capacity has been installed after 2017. By administrative district, about 24.31% of the total number of photovoltaic system facilities surveyed was found in Jeollabuk-do, showing the largest number.

This study attempted to estimate oil consumption and carbon dioxide emissions caused by the use of construction equipment and machine at the construction operation phase in 27 apartment construction sites. To calculate oil consumption at the construction operation phase of the apartment buildings, the construction equipment & machine-used construction items were classified using the construction statements. Then, oil consumption at the construction operation phase was obtained in 27 apartment construction sites. For carbon dioxide emissions, the construction items were categorized by construction type and building based on the estimated oil consumption. In terms of carbon dioxide emissions by building, ‘welfare facilities’ were the highest with 11,508.86g-CO₂/㎡(27%). In terms of carbon dioxide emission by construction type, on the contrary, ‘building construction’ was the largest with 5,453.25g-CO₂/㎡(89.34%).
