Figure 5
The graph titled “Case A” shows horizontal axis markings, from 6 over 8 to 6 over 30, and from 7 over 1 to 7 over 10, with a unit increment in the denominator. The vertical axis is labeled “Air temperature (degrees Celsius)” and ranges from 0 to 32 in increments of 2 degrees. The legend of the graph includes the Purple line for Average indoor air temperature (living spaces) (degrees Celsius), green line for Kitchen Space air temperature (degrees Celsius), red line for Toilet air temperature (degrees Celsius), and Dotted purple line for F M I outdoor air temperature (degrees Celsius), and blue bars for cloud amount (1 over 8). Two reference lines are as follows: Indoor overheating reference line at 27degrees Celsius in a black dotted line, and Heatwave reference line for 25 degrees Celsius in a purple dotted line. The cloud amount line, ranging from 0 to 8, corresponds to varying levels of cloudiness. The F M I line shows the outdoor air temperature, ranging from 4 to about 31 degrees Celsius, with peaks at 31 and 24 degrees Celsius marked. The other three lines lie above the F M I line with small amplitude, with a peak at 28 degrees Celsius for indoor air temperature. The other three lines intersect the F M I between 6 over 21 and 7 over 3.Indoor and outdoor temperatures in – the summer heatwave of the year 2022: case A
