A team of �°������ϲ���Ļ��Ϣ Davis students are tackling the California drought through innovative housing design with their entry for the U.S. Department of Energy’s 2017 Solar Decathlon.

The design focuses on cutting typical residential water use in half while maintaining the same level of comfort at an affordable price.

Held every two years, the Solar Decathlon challenges collegiate teams to design, build, and operate solar-powered houses that are cost-effective, energy-efficient, and attractive. National teams will compete in Denver, Colorado in October 2017. The winning team best blends affordability, consumer appeal, and design excellence with optimal energy production and maximum efficiency.

Design plans are due to the competition this month, with construction scheduled to begin in January on a field beside the �°������ϲ���Ļ��Ϣ Davis West Village community.

A Very, Very, Very Fine House

California is experiencing one of the most severe droughts in the state's recorded history, now in its fifth consecutive year. In many cases, water usage has been restricted for home and agricultural use.

With its Our H₂Ouse (“our house”) design, the seeks to create a home that will change water consumption for the better in the face of ongoing and future water demands.

The home design's features include systems for rainwater catchment, graywater and blackwater re-use, and a two-way communication system to monitor water and energy consumption.  

“We’re designing the house to feature a dual-energy and water-use feedback system that will inform the occupants about their energy and water usage and hopefully take some stress off of the environment so it can regenerate," said Justin Dela Cruz, spokesperson for the �°������ϲ���Ļ��Ϣ Davis Solar Decathlon team and a �°������ϲ���Ļ��Ϣ Davis communications major. “This house is trying to tackle the drought in California. Taking a systems approach to this reduction is just the first step. True reduction lies in the hands of the people who live in the house and those in the surrounding community.”

Building on Success

At the 2015 Solar Decathlon at Irvine, California, �°������ϲ���Ļ��Ϣ Davis’ Team Aggie Sol took home a first place win for affordability and commuting with designed for farmworkers.

Preparing for the Solar Decathlon is a campuswide, multidisciplinary effort involving team members from many academic backgrounds, including design, engineering, communications and economics. The team is assisted along the way by �°������ϲ���Ļ��Ϣ Davis faculty and staff. Engineering professor Frank Loge, director of the , serves the team again as faculty adviser, a role he held for the 2015 competition.
