Hi -- If you are looking for a good way to examine the tradeoff between solar gain and heat loss on specific windows, the RESFEN program (free) is good:
LBNL Window & Daylighting Software -- RESFEN
It does a full hour by hour simulation for your climate and it includes solar heat gain and window orientation.
