33 Pacific Bell Park Location: San Francisco, CA A wide range of units were installed throughout the park. They include small horizontal heat pumps, twin circuit verticals, V-Cube Lites, and V-CubesMammoth worked with the developer to provide special arrangements and performance that better suited the layout of the park.
34 Viacom Location: New York, NY Viacom selected V-Cubes and horizontal heat pumps that worked with their open and closed ceilings. Quick delivery was a key point for many units.Some units utilize DDC controls and VAV to service the studio and larger areas of the building.
35 Quality Living Assisted Care Facility Location: Omaha, Nebraska Quality Living added a new east campus to their facility. The new campus utilized Mammoth high efficiency geothermal heat pumps.The new addition operates more than twice total hours at less cost than the older campus with a conventional boiler and tower system.
36 Texas Motor Speedway Condominiums Fort Worth, TX Mammoth was awarded the project because of energy savings, noise control, flexibility in right/left hand configuration and meeting the tight closet fit.
