The U.S. Department of Energy Solar Decathlon® is a collegiate competition, comprising 10 contests which challenge student teams to design and build highly efficient and innovative buildings powered by renewable energy. Winning teams blend design excellence and smart energy production with innovation, market potential, and building efficiency. The Solar Decathlon offers collegiate teams a unique opportunity to develop critical career skills that prepare them to enter the clean energy workforce. This Solar Decathlon gives teams the option to participate in one of two Challenges: the Design Challenge or the Build Challenge. 

Design Challenge


The US Department of Energy (USDOE) hosts the competition, which culminates at the National Renewable Energy Laboratory in Golden, Colorado. In 2020 we placed first in the Urban Single-Family category of the USDOE Solar Decathlon Design Challenge. In 2021 we placed first in the Mixed-Use Multi-Family Division of the USDOE Solar Decathlon Design Challenge. Back-to-back feels good.

Build Challenge

In 2021 we will begin our first Build Challenge which will take place over 2 years, completing in Spring 2023! 

Laundry Haus (2021)

Laundry Haus was Third Quadrant Design's first attempt at a larger scale building. We transformed a light industrial warehouse at the end of its life into a high performance 5 story mixed-use development. Building on our success in 2020, we hoped to use our momentum to compete in a more challenging and competitive division -- and it worked. We won 1st place in the Mixed-Use Multi-Family Division, beating out schools like Cooper Union, Harvard, Berkeley, and the University of Arizona. Laundry Haus is regeneratively designed, and holds building resilience and occupant comfort as paramount in attempts to create a holistic community to live, work, and play.

Solis House (2020)

Our 2020 submission to the Solar Decathlon's Urban Single-Family Home category won first place! Solis House was Third Quadrant Design's first submission into the competition. It features on-site solar power and food production, rainwater harvesting, passive cooling, hot water recovery, and so much more (check out the video above).
