Figure 5
There are 8 panels labeled a through h, each plotting weekday and weekend hourly consumption with error bars. In all panels, the horizontal axis is labeled “Time (hours)” and ranges from 0 to 23 in increments of 1 hour. In each panel, a legend identifies two lines: Weekday and Weekend. Panel a is titled “Hourly consumption for H V A C (Electricity) in January” and the vertical axis is labeled “H V A C (electricity) (kilowatt-hours)” ranging from about 30 to 65 in increments of 5 kilowatt-hours; weekday values rise sharply after hour 5 from about 33 to about 55 at hour 6, then stay high around 54 to 63 through hour 23, while weekend values remain lower around 33 to 44 with small peaks near hours 12 and 18. Panel b is titled “Hourly consumption for H V A C (electricity) in July” and the vertical axis ranges from about 20 to 70 in increments of 5 kilowatt-hours; weekday values jump from about 28 at hours 1 to 5 up to about 57 at hour 6, peak around 70 at hours 12 to 15, then decline to about 58 by hour 23, while weekend values stay nearly flat around 26 to 30. Panel c is titled “Hourly consumption for lighting in January” and the vertical axis is labeled “Lighting (electricity) (kilowatt-hours)” ranging from about 0 to 25 in increments of 5 kilowatt-hours; weekday lighting rises from about 11 at hour 0 to about 20 at hours 5, drops to about 12 at hour 7, then stays around 19 to 20 from hours 10 to 16 before declining to about 10 by hour 20, while weekend values stay lower around 6 to 12. Panel d is titled “Hourly consumption for lighting in July” and the vertical axis is labeled “Lighting (electricity) (kilowatt-hours)” ranging from about 0 to 25 in increments of 5 kilowatt-hours; weekday lighting increases from about 10 at hour 0 to about 22.5 at hour 5, dips near hour 7, then peaks around 24 to 25 between hours 10 and 15 before decreasing to about 12 by hour 23, while weekend values stay near 8 to 12 with a sharp dip of 5 at hour 9. Panel e is titled “Hourly consumption for other usages in January” and the vertical axis is labeled “Other Energy Use (kilowatt-hours)” ranging from about 14 to 20 in increments of 1 kilowatt-hour; weekday values rise sharply after hour 8 from about 16.4 to a peak around 21 at hour 13 then drop to about 15.6 by hour 23, while weekend values stay flatter around 14.5 to 15.5. Panel f is titled “Hourly consumption for other usages in July” with vertical axis ranging from about 14 to 22 in increments of 2 kilowatt-hours; weekday values rise after hour 7 to a peak near 22 at hour 12, then steadily decline to about 15 by hour 23, while weekend values remain low around 14 from hours 0 to 5 and then stable around 15 to 16. Panel g is titled “Hourly consumption for space heating (gas) in January” and the vertical axis is labeled “Space Heating (gas) (cubic meters)” ranging from about 0 to 55 in increments of 5 cubic meters; weekday values peak around hours 4 to 6 near 35 to 40, then decline to a minimum near hour 13 around 5, then increase again toward hour 23 near 34, while weekend values show a similar but lower pattern with wide variability. Panel h is titled “Hourly consumption for space heating (gas) in July” and the vertical axis ranges from about 0 to 300 in increments of 50 cubic meters; weekday values rise from about 108 at hour 0 to peaks near 230 between hours 6 and 10, dip to about 120 around hour 14, then rise again toward about 190 by hour 23, while weekend values remain lower around 80 to 140 with a mid-day dip near hour 15.
