The new $13 million JD Ross Maintenance Headquarters facility in Vancouver, WA, is nothing, if not energy efficient. Utilized as the Bonneville Power Administration’s (BPA) Southwest Washington base for transmission line for substation maintenance crews, substation operators, control technicians and support engineers, the building is 'Net Zero' in terms of energy use. Fitting with that goal, the building's architect equipped the structure with bifold doors from Schweiss Doors.
