Embodied energy analysis of building materials: An improved IO-based hybrid method using sectoral disaggregation

This study investigated and improved an IOH method of embodied energy calculation. Using the improved method, the embodied energy of commonly used building materials was calculated and evaluated. The results demonstrate a significant difference after disaggregating the relevant industry sectors. The study concludes that using embodied energy values without industry sectors being disaggregated can cause significant errors in a building's embodied energy calculation.
