EVALUATION OF NON-RESIDENTIAL BUILDINGS USING HOURLY CO₂ EMISSION FACTOR

Abstract

CO₂ emissions from building power consumption are calculated using the same CO₂ emission factor throughout the year. However, with the spread of renewable energy, the actual CO₂ emission factor changes from time to time, and the amount of energy consumption in buildings also fluctuates, making true evaluation difficult with conventional calculation methods. In this research, after calculating the hourly CO₂ emission factor, the CO₂ emissions of non-residential buildings are calculated by region and by building use. The verification revealed that the peak CO₂ emissions of buildings are concentrated in the evening, not in the early afternoon.
