A Cool Day in the Sun
Spearheaded by the U.S. Department of Energy, the Solar Decathlon throws down the gauntlet to university students: design and construct a fully solar-powered house. These innovative houses undergo a barrage of tests and trials to determine the cream of the crop. At its core, the competition aims to spotlight the practicality of solar energy for everyday consumers while equipping students with hands-on expertise in real-world design and construction.
Back in 2002, I had the honor of being part of the University of Virginia team for the inaugural Solar Decathlon. Armed with a Mechanical Engineering degree, my primary focus revolved around fine-tuning the plumbing and HVAC systems of our pride and joy, affectionately known as the Trojan Goat.
Hours upon hours were poured into drafting and redrafting, followed by relentless toil in building and testing. Our goal? Crafting a setup that minimized energy wastage and maximized efficiency, ingeniously repurposing solar energy for secondary and tertiary uses. If the primary domestic hot water tank didn’t need heating, we diverted the energy to warm up the backup tank or the water supply for the radiant floor heating system. And if all else failed, we stashed the surplus heat in a colossal custom-made storage tank for future use.
On the dawn of the competition’s first day, I anxiously observed as the water temperature surged upon exiting the solar panels, a tangible sign that our system was indeed harnessing solar energy to produce hot water. It was a defining moment, a testament to our team’s dedication and ingenuity.
For me, that was one of the competition’s biggest highlights.
