| Abstract |
This study analyzes in detail greenhouse gas emissions in building sector. To this end, this study used data on building characteristics
(including building type, region, and construction year) and monthly energy consumptions (including electricity, city gas, and district heat) for
all buildings from 2015 to 2018. These data were collected from the National Building Energy Database and the energy consumptions were
converted into greenhouse gas (GHG) emissions. The total amount of GHG emissions from the building sector has increased steadily from
2015 (118.1MtCO2eq.) to 2018 (132.6MtCO2eq.). On the other hand, the more recently constructed buildings had lower GHG intensities. This
result shows that strengthening building design criteria was effective on the reduction of GHG emissions in buildings, and that the increased
buildings contributed to increasing GHG emissions of the building sector. In addition, sales facilities are thought to have the largest reduction
potential as they had the highest amount of GHG emissions and GHG intensity. This study is expected to help establish new policies for
GHG reduction in building sector as well as to evaluate the effects of existing policies. |
