2020-21 Challenge

In the 2020-21 Challenge, about 1000 students from backgrounds including engineering, architecture, agriculture, building energy performance, business administration, disaster mitigation and management, planning, microbiology, naval architecture, physics, and transportation, among others participated. They came from 103 academic institutions across the country. They learned about building science and net-zero energy-water, and got hands-on experience on live, real projects. They learned soft skills of team work and the use of simulations to predict building performance. They collectively worked on 12 million square feet of new construction buildings to make them net-zero energy-water, showing how 6.3 million tonnes of CO2 emissions can be abated over the life of these buildings. The finalists’ projects demonstrated that these buildings could be built affordably while reducing energy consumption by at least 50%.


In the 2020-2021 Solar Decathlon India Challenge, participating teams designed buildings in one of the four Divisions:

  • Multifamily Housing
  • Educational Building
  • Office Building
  • Community Resilience Shelter

Designs had to comply with byelaws, codes, and standards and strive to meet special requirement of the real estate partner. The competition guide provides more details about the guidelines and rules. Check out the final reports submitted by the finalists.

Ten Contests in the 2020-21 Challenge

In the 2020-2021 Solar Decathlon India, participants worked to excel in the following Ten Decathlon Contests:

  • Energy Performance;
  • Water Performance;
  • Resilience;
  • Affordability;
  • Environmental Quality and Comfort;
  • Scalability and Market Potential;
  • Architectural Design;
  • Engineering Design and Operations;
  • Innovation;
  • Presentation

Participants demonstrated progress in all 10 contests. This enabled students to approach building design in an all- encompassing manner. The competition guide provides more details about the Contests.
