News: The 2017 Solar Decathlon will be held in suburban Denver. Link
When the contest was held in Irvine, California, I complained: "This is a significant and disappointing decision because it confirms that the contest is about solar electricity, not solar heating. In Irvine in October, the average temperature is 64˚F, practically room temperature! ... Why not hold the contest in Minneapolis a month later?"
In October in Denver, the average temperature is 49˚F (High - 65; Low - 36). Heating will be needed!
