Comfort Zone Contest

(100 points)

For the U.S. Department of Energy Solar Decathlon Comfort Zone contest, teams design their houses to keep temperature and humidity steady, uniform, and comfortable. Full points are awarded for maintaining narrow temperature and relative humidity ranges during specified periods of time.

For full points, the houses must maintain:

  • Temperature between 71°F (22.2°C) and 76°F (24.4°C)
  • Relative humidity below 60%.
