ABSTRACT
ABSTRACT During their lifecycle, buildings consume energy in the form of embodied energy and operating energy. Both these energy components must be optimized to reduce the building's carbon footprint effectively. However, measuring and evaluating lifecycle embodied energy (LCEE) is more challenging, complex and dataintensive than operating energy usage. This is because existent embodied energy calculation methods suffer from issues of incompleteness, unreliability, or poor data quality. A systematic review of literature shows that the input-out hybrid (IOH) method is the most ideal approach to calculate embodied energy. However, the reliability and specificity of the IOH method is questionable. This paper discusses the issues related to embodied energy (EE) calculations and also proposes an economic input-output-based hybrid (E-IOH) model to improve the reliability and specificity of data used for embodied energy calculation. The E-IOH model will significantly help in reducing the data and the computational requirements associated with the process of EE calculation.
