Approximately what percentage of energy used in larger office buildings is electrical energy?

In larger office buildings, electrical energy typically accounts for a significant portion of the total energy consumption. The correct answer, indicating that approximately 67% of energy used in these types of buildings is electrical energy, reflects the high reliance on electricity for various building systems.

This includes lighting, heating, ventilation, air conditioning (HVAC), and office equipment, all of which predominantly operate on electrical energy. As energy efficiency initiatives become more prevalent, understanding the proportion of electrical energy use is crucial for facility managers, who aim to optimize energy consumption and reduce operational costs.

Other percentage options such as 50%, 75%, and 80% either underestimate or overestimate the typical share of electrical energy use in larger office buildings, thereby highlighting the importance of accurate metrics for effective energy management in facility operations.
