That is why, next two groups of objects are the orientation of glazing and
window-to-wall ratio (WWR%). In the considered alternatives (WWR%) ranges
from 10 to 80 % for 4 orientation—north, south, west, and east, it includes both
qualitative criteria and quantitative criteria.
In the group dealing with facade orientation, we assess two criteria—comfort
and daily heat gain, which in our case are equally important.
In the group dealing with the area of glazing, we assess more criteria: heat gains
(0,3), comfort (0,2), price for glazing (0,15), aesthetics (0,15), price for wall
construction (0,1) and maintenance (0,1). The variation of heat gains shows which
orientation and area of glazing will produce the highest heat gains. Here, quali-
tative criteria are very important—comfort in particular, the sense of well-being at
higher or lower solar exposure.
