The chart displays hourly electricity demand over a one-week period from Monday 08:00 to Sunday 20:00 along the horizontal axis. The left vertical axis shows electricity demand in kilowatt hours from 0 to 70, while the right vertical axis shows electricity demand in watt hours per square metre from 0 to 3.06. Each bar represents an hour and is stacked with six components: Outdoor lighting, Tower crane, S D B 1, S D B 2, S D B 3, and Drying room. Total demand varies between approximately 30 and 68 kilowatt hours. Weekday patterns show clear daily peaks, with higher demand during daytime hours, around 08:00 to 20:00, reaching about 60 to 68 kilowatt hours, and lower demand during nighttime, around 30 to 40 kilowatt hours. The largest contributions come from S D B 2 and S D B 3, followed by S D B 1, while Outdoor lighting, Tower crane, and Drying room contribute smaller portions. Toward the weekend, Saturday and Sunday, overall demand decreases, with peaks around 45 to 50 kilowatt hours and reduced variation compared to weekdays.Hourly electricity usage at Site B for the week starting 9 March 2020
