Teams design their houses to maintain steady, uniform indoor environmental conditions. Full points were awarded for maintaining narrow temperature and relative humidity ranges inside.

For full points, the team houses had to maintain:

  • Temperature in the range of 72°F (22.2°C) to 76°F (24.4°C)
  • Relative humidity between 40% and 55%.
