The Solar Decathlon and the Weather

Several colleges are participating in the "Solar Decathlon", a contest to build green housing within a set of constraints, with the model house erected on the Mall, or this year in West Potomac Park.  U of MD won the architectural award.  This year since Tropical Storm Lee went through earlier this month the sun has been in little evidence.  That's unfortunate, because many of the features of such houses depend on reasonably sunny weather, which the DC area usually has in September, but not this year.
