Giant Lacewing

Found this guy at work. After checking in, walking out the front doors, I found him stuck between the two sets of doors. When I opened the front door he flew out and landed on the door so I could take his picture. I believe it's a giant lacewing. Every source I can find says they're rare and little is known about them. He was a little over an inch long, much bigger than the green lacewing which is very common around here this time of year.
