2014 ASHRAE TEcHnology AwARd cASE STudiES thereby reduce the peak cooling load on the geothermal heat pump energy plant. The geothermal heat pump energy plant consisting of the magnetic-bearing chiller, pumps, variable speed drives, power wiring and controls was factoryassembled at an ISO-9001 facility and shipped to the site in five portions for site assembly. This significantly reduced construction and commissioning time as well as risk related to varying Second floor corridor area with daylight windows and light diffusers. on-site conditions and quality control. Conclusions Several conclusions can be drawn from this project. First, the application of anticipatory predictive controls on a geothermal HVAC system can provide additional energy saving benefits not possible with traditional real-time control approaches. Additionally, significant system efficiencies and energy cost reductions are possible in climates where the mean earth temperature allows some portion of the cooling load to be addressed directly by GHX loop water without the operation of a chiller. Finally, actual building operation is always different from a design energy model and controls that track, analysis and adapt to these differences will provide more optimum operation over time than a control system that is simply commissioned and left in a static operational condition. www.info.hotims.com/49804-42 88 ASHRAE JouRnAl ashrae.org M ay 2 0 1 4
