Abstract |
This study analyzes the possibility of achieving the goal of carbon neutrality in building sector by 2050. This study used data on building
energy intensity by building type and gross floor area of buildings. For this data, we get the data from the National Building Energy
Database and national statistical database from 2015 to 2019. The types of buildings for analysis are detached houses, apartments, commercial
buildings and educational buildings. These energy consumptions of building sector were converted into greenhouse gas (GHG) emissions. To
this end, the prediction of GHG emissions in building sector has increased steadily from 156.9 million ton CO2e in 2020 to 217.8 million ton
CO2e in 2050. The suggested reduction scenarios in this study were 5 scenarios as mandatory scenario for zero energy building for new
buildings, green-remodeling scenario for existing buildings, dissemination scenario for high-efficiency energy facilities, scenario for behavior
improvement and scenario for low carbon energy source. The result of this study shows that the potential reduction emissions is about 107.7
million ton CO2e by these scenarios in 2050. This result told us that the possibility of 2050 carbon neutrality in Korea’s building sector is
low based on these scenarios. This study suggested the necessity for very challenging reduction plans and is expected to help establish the
reduction policies for building sector. |
