Partnerships with lighting center aim to achieve deep sustainable energy

This is Science Today. One of the goals of the California Lighting Technology Center at the University of California, Davis is to achieve deep and sustained energy throughout the nation. Michael Siminovitch, director of the center, says a critical way to achieve this is through their many business partnerships, including a current project with Wal-Mart.

Siminovitch:   Wal-Mart is very interested in implementing day lighting solutions into their big box facilities. And so they have a lot of skylights and they have a lot of electric lighting. The big challenge with sky lighting and electric lighting is how to make these things work seamlessly together. We do a really good job in this country of day lighting buildings, but we do an absolutely terrible job of what's called daylight harvesting. We don't back off the electric lights in a systematic way with the availability of daylight.

Narrator:       So, a team of researchers at the California Lighting Technology Center are working with Wal-Mart and the company WattStopper to develop a sensor prototype that will simplify day lighting approaches and save energy. For Science Today, I'm Larissa Branin.
