Stanford students are planning to revolutionize green home construction with a new standardized platform. A first home based on this concept is being built right now (you can even follow the progress via its very own YouTube channel). This solar-powered, zero-emission house is Stanford’s entrant in the Solar Decathlon, a biennial competition run by the U.S. Department of Energy. The 2013 competition will feature solar homes from 20 collegiate teams from four countries.
At the heart of the project is the Start.Core, a central unit that contains all the plumbing, utilities and appliances and manages the house’s energy usage. The team believes that a standardized unit like the Start.Core could transform green home construction.
“We want to inspire industry to think about houses that can be built more like cars,” said project manager Derek Ouyang, a double major in civil engineering and architectural design.
The ability to mass produce basic but critical elements will make it possible to improve quality control and upgrade equipment with new technology as it becomes available, while at the same time allowing customizability. “The Start.Core is like an engine for homes, and you can build any shell you want around it,” he said.
Most of the students had no carpentry experience before beginning the build, but they are gaining on-site training from five instructors from the Carpenters Union, one of the project’s sponsors. After a few hours on the site with the expert instructors, Ouyang said, most students feel very comfortable with the construction equipment.
Learning their way around a construction site, however, hasn’t been the only challenge.
“Every single day we run into five unexpected issues,” Ouyang said. “Most of them are structural. When you’re designing something using 3-D software, it looks really easy to drop in a beam or a screw. But then you finally get building, and you realize you can’t swing a hammer in the space where you planned to put a nail. I’ve spent most of my time so far going around the site figuring out on-the-spot design changes.”
Earlier this week, 100 6th-graders from nearby Nueva School visited for a tour of the house. A public house-warming ceremony is scheduled for Earth Day, April 22, and the team has plans for more educational tours this summer, when the core systems are fully integrated. Ouyang said that these outreach efforts will help people think about improving their day-to-day energy consumption.
“We’re packaging behavioral design into the Start.Core, to help people become net-zero as well,” Ouyang said. “The more aware you are of your daily energy usage, the more likely you are to improve your habits. That’s hard to do just based on an electric bill at the end of the month.”
This summer the team also will be fine-tuning the operating systems and confirming that the house is really operating at net-zero emissions.
Later this summer, the team will practice dismantling and re-assembling the house in preparation for the competition, which will be held October 3-13 at Orange County Great Park in Irvine, Calif.
