Health and Comfort Contest (100 points)

New for 2017, the U.S. Department of Energy Solar Decathlon Health and Comfort Contest combines new contest components with those from previous Solar Decathlon competitions. Teams are challenged to build a house that minimizes the flow of cooled air in summer or heated air in winter to the outdoors, operate heating and cooling systems that keep temperature and humidity steady, all while maintaining healthy indoor air quality.

To earn full points for this contest, teams must maintain:

  • Temperatures between 68°F (20°C) and 74°F (23.3°C)
  • Relative humidity between 35% and 60%
  • Indoor CO2 levels at less than 1,000 parts per million
  • A tight building envelope that minimizes airflow from the outside to the inside of the house and from the inside to the outside, thus reducing amount of energy required to heat or cool that air.
