Changes in A901 1.21 (rel. to 1.2)

• Any fenestration having a slope of less than 60 degrees from the horizontal is now considered a skylight and will be available in the skylights tab.
• The opaque parts of a skylight get the same U-value as the fenestration part of the skylight.

Fixed bugs

• Fixed a bug in reporting wall areas in the "Shading and Fenestration" tab.
• Fixed a bug where the skylight fenestration type in the baseline wasn't in line with tables 5.5-1 to 5.5-8.
