With HVAC-Calc, you just follow the numbered steps. Because we are adding this window to the West Wall, the program already knows the direction. Next we just select the type of window from the lists. In the real program (not on this screen shot), if you hold your mouse over a list, the help at the bottom will give you specific advice on the particular item.
Now we click on Add and that is all there is to adding a Window to the Wall.
Do you see the Resutls tab, just to the right of the word "Window"? The next screen shows the results so far. Next Screen on tour.
