Abstract: Buildings consume approximately half of the annual energy supply of the United States in their construction and operation. To effectively decrease this extensive energy footprint, both embodied and operating energy must be quantified and optimized. Although validated standard methods are available to compute operating energy, quantifying embodied energy is still complicated and inconsistent. Among the available embodied energy calculation methods, an input-output-based hybrid (IOH) method has the potential to offer a more complete calculation. However, its calculation lacks specificity and reliability, which can be improved using suggestions provided by literature. Studies across the globe have proposed techniques such as sectoral disaggregation to enhance not only the specificity and reliability, but also the completeness, of an IOH method.
