Health and Comfort Contest (100 points)
New for 2017, the U.S. Department of Energy Solar Decathlon Health and Comfort Contest combined new contest components with those from previous Solar Decathlon competitions. Teams were challenged to build a house that minimized the flow of cooled air in summer or heated air in winter to the outdoors, and operated heating and cooling systems that kept temperature and humidity steady, all while maintaining healthy indoor air quality.
To earn full points for this contest, teams had to 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.
For complete information, see the Solar Decathlon 2017 rules. Solar Decathlon teams should always refer to the rules.
