Figure 9
The graph titled “Case D” shows horizontal axis markings, from 8 over 29 to 8 over 31, and 9 over 1 to 9 over 19, 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 black 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 0 to about 18 degrees Celsius, with a peak at 18 degrees Celsius marked. The toilet air temperature line is at the top of the graph, with fluctuation. The other two lines lie above the F M I line and below the toilet air line with small amplitude, with a peak at 25 degrees Celsius marked for indoor temperature.Indoor and outdoor temperatures and cloud amount 2022 in case E
