Casinos combine a variety of space types under one roof. Hollywood Casino in Toledo, Ohio, is no different. The 177,000-sq-ft main casino level includes 150,000 sq ft of gaming space and five restaurants, while the 167,000-sq-ft lower service level includes administrative and employee areas and a 276-space valet-parking garage. For heating and cooling the entire building and supporting owner Penn National Gaming Inc.’s pursuit of LEED (Leadership in Energy & Environmental Design) certification, mechanical-engineering designer Concord Atlantic Engineers Inc. recommended rooftop air handlers and centrifugal chillers from Daikin Applied.
