EAST LANSING, Mich. (AP) — Michigan State University is trying to turn one of its oldest science buildings into a model of energy efficiency under a new $7 million project at Anthony Hall.

Anthony Hall opened in 1957, and the Michigan State trustees voted Dec. 14 to begin work on improving its energy use.

The university says the goal is to cut energy consumption by 37 percent and says the work will pay for itself in 10 to 13 years.

The project's features include more efficient air ventilation in laboratories, cooling tower improvements and a conversion to direct digital climate controls.

The work is part of the Better Buildings Challenge, a national initiative that promotes the construction and retro-commissioning of more energy-efficient buildings nationwide.
