BEI provided mechanical, electrical, plumbing and fire protection engineering for the new 32-story hotel for the Greentown Casino in Detroit, Michigan. The Hotel Podium Levels include over 60,000 square feet of retail, lounge, restaurant with bar, ballrooms, meeting rooms, prefunction area, separate restaurant and ballroom kitchens, administrative offices, back of house areas, computer room, and a fitness center in addition to the 400 guest suites. The hotel and adjacent parking structure are connected to the casino by an air conditioned and heated pedestrian connector and sky bridge.

Chilled water is supplied to air handling units, suite fan coil units, ice machines and fan coil units serving elevator and electrical rooms. The heating plant includes modular type gas-fired boilers and hot water to hot water heat exchangers that supply hot water to air handling units, suite fan coil units, miscellaneous supplemental heating units, and domestic hot water to plumbing fixtures located throughout the building.

Variable air volume and constant volume air handling units serving the Podium Levels are located in a mechanical room on Level 6. Each unit includes a hot water heating and chilled water coil. Vertical fan coil units provide heating and cooling in each of the suites.

A direct digital building management system provides temperature control and monitoring of all mechanical systems.

The building is fully protected by standpipes in the stairwells and a wet fire protection sprinkler system. A fire pump and domestic water booster pump package are installed in a pump room located in the parking structure.
