FYI:
If all your interested in, is the calculation of minimum compliance with the minimum window area for a Room/Zone. I would just use a expression property with the zone(s).
Much simpler and no registration required.
If you need to calculate the daylight factor, many regulators will accept a simplified formula of:
DF = 0.1 * (window area/room area (zone)) * 100 usually greater than 2%. Also can be calculated on a zone basis with a expression property.
You could also create a pass/fail property for each zone using a expression property.
