Energy Consumption Model for Open-Space Geometry Building: A Study Case in Jakarta

Abstract

 Abstract —Occupant behaviour and their activity contribute to entire building energy consumption. This study proposes energy consumption prediction model which integrates appliances category, occupancy rates and occupant activity. Site measurement method is used in collecting all appliances along with their operating characteristics. Occupant activity and working behaviour are obtained through questionnaire survey. Simulation results show that energy consumption from base appliances is stable during the working day whereas energy consumption of occupant activity and personal appliances is more fluctuate due to occupancy rates of office building. Validation process with actual energy consumption shows that simulation energy consumption using the proposed model has an average accuracy rate 94%. This model is applicable to predict the energy consumption in open-space office building by knowing occupant behaviour and appliances
