Water Campus Redevelopment
IMEG was the engineer of record for Denver Water’s Operations Complex central utility plant and the 185,000-sf administration building, which has achieved LEED Platinum and WELL Building certifications, targets net zero energy, and is One Water designed.
The central utilities plant provides chilled water, hot water, potable water, and 13.2kV medium voltage electrical. It uses non-traditional systems to optimize energy use across the Operations Complex, serving the trades, fleet maintenance, meter test facility, and warehouse buildings, which were designed by another firm.
The primary systems are magnetic centrifugal heat pump chillers, which provide cooling and heating through a balanced load. For peak heating and cooling, the plant uses 60,000 gallons worth of thermal energy storage and high efficiency air source heat pumps to cover these rare peak events. The plant also is connected to a 54-inch potable water distribution conduit, which acts as another source/sink of the complex’ energy, in addition to being a direct “water side” economizer source. The administration building’s primary mechanical system is radiant heating and cooling that is integral to the building’s structural post-tension slabs. In addition, a dedicated outside air energy recovery system provides ventilation air through an access floor and underfloor air distribution system.
IMEG also provided designs for the three stone buildings, the wellness building, and the parking garage.
