At this stage, the lighting charts (Table 6) were normalized and then subtracted from A/C functions (Table 5) and finally, the algebraic addition of the two functions was carried out in The analyzed information as a whole and the results listed in Table 6 show that the square shape (Sample B) is the most optimal condition followed by the rectangular shape. In other words, the higher the length-to-width proportion, the higher the energy consumption. Accordingly, Sample H’s plan (length-to-width ratio of 4.1) compared to Sample B’s plan (length-to-width ratio of 1) raises the building energy consumption by more than 10 KWH/m2.
