Three of Hanson’s energy and commissioning employees — Robert Knoedler, Nate Boyd and Bradley Perrott — spoke June 8 at the ASHRAE Central Florida Chapter’s High Performance Building Conference at the University of Central Florida. The event provided an opportunity for members of the heating, ventilating, air-conditioning and refrigeration industry to share knowledge about trends in high performance building design, operations and construction. Hanson was a sponsor for the conference.
