   - `height`: [float] Height of the building, in m. Default value is 3.35.
   - `width`: [float] Width of the building, in m. Default value is 3.05.
   - `window1`: [str] Position of window 1 (bottom), in cartesian coordinates, in meters. Default value is '.38 .22 2.29 .85'. These values represent respectively: starting X, starting Y, width, and height. More specifically, the origin of x=0; y=0 is the ground level and the south facade is always at -y, north at +y, west at -x, and east at +x.

   - `window2`: [str] Position and size of window 2 (middle), in cartesian coordinates, in meters. Default value is  '.38 1.07 2.29 .85'. These values represent respectively: starting X, starting Y, width, and height. More specifically, the origin of x=0; y=0 is the ground level and the south facade is always at -y, north at +y, west at -x, and east at +x.
