Investigating Users’ Perspectives in Building Energy Management System with an Extension of Technology Acceptance Model: A Case Study in Indonesian Manufacturing Companies

This study investigates factors that may influence users’ perspectives in utilizing energy management system. An extended model of the Technology Acceptance Model (TAM) with two external factors, compatibility (C) and technology complexity (TC), was developed to evaluate the implementation of the Building Energy Management System (BEMS) in Indonesia's manufacturing industries. 258 questionnaires were analyzed via the structural equation modeling and the result shows that both C and TC influence user's intention to use BEMS through the user's attitude, perceived usefulness and perceived ease of use. The findings can be served as guidelines for design improvements of similar energy management systems.
