Potential Reduction of Greenhouse Gas Emissions for Buildings by Renewable Energy

This study aims to propose a renewable energy scenario for the building sector to reduce greenhouse gas (GHG) emissions and to estimate the potential reduction of emissions in the building sector by 2050, based on this scenario. The types of buildings used for analysis are detached houses, apartments, commercial buildings, and educational buildings. The activity data for the building sector’s projection model are building use type, gross floor area of building use, building energy intensity, and GHG emission factor. The prediction of GHG emissions from this scenario is that they will increase steadily from 2020, peak in 2039, and start declining from 2050. The result shows that the potential reduction in emissions will be about 43.1 million tons of CO2e against business as usual, in 2050.
