How much energy does it take to power a skyscraper?

The energy required to power a skyscraper varies significantly based on its size, design, and use, but on average, a typical skyscraper may consume between 15 to 100 million British thermal units (BTUs) per year. This translates to approximately 4,400 to 29,000 megawatt-hours (MWh) annually. Energy use is influenced by factors such as heating, cooling, lighting, and the number of occupants. Advanced energy-efficient technologies and designs can significantly reduce these energy demands.
