ANDERSONVILLEā€”No one was injured, but three workers were briefly trapped when a roof collapsed at a factory in Andersonville on Saturday, possibly because of ice and snow buildup, authorities said.

The roof collapse was reported at about 7:40 p.m. Saturday. Seven people were inside the Carton Service/Pharma Packaging building on First Quality Drive at the time, said Del Kennedy, chief of the Andersonville Volunteer Fire Department.

Four workers were able to make it out, and firefighters had to help the other three escape from a break room, near the front of the building, at the edge of the factory space behind it. All the workers were in or near the break room at the time of the collapse, Kennedy said.

He estimated that 50 percent of the roof, which was about 40 feet above the factory floor, had collapsed over that portion of the building. There was only a small crew working at the time, Kennedy said. [Read more…]

ORNL roof, attic design proves efficient in summer, winter

A new roof-and-attic system tested at the Oak Ridge National Laboratory keeps homes cool in summer and prevents heat loss in winter, a press release said.

Among the features designed to improve efficiency are a ventilation system that pulls air from the underbelly of the attic into air space above the roof, the release said.

“Heat that would have gone into the house is carried up and out,” says Bill Miller of ORNL’s Building Envelope Group. “And with a passive ventilation scheme, there are no moving parts, so it’s guaranteed to work.”
