MEP was brought on board as a consultant to provide professional engineering design services for a portion of the campus at Missouri University of Science & Technology. The geothermal system was designed as a Hybrid and is expected to replace the aging steam plant. The balance of the heating and cooling load is a combination of heat recovery chillers, heat exchangers, heat pumps gas fired boilers and existing distribution equipment. The geothermal system will be utilized for the base heating and cooling with the reuse of the existing chilled water system for cooling peaks and new hot water boilers for heating peaks.
Geothermal well fields were separated into three power plants (Straumanis-James, Science Facility and the future James E. Bertelsmeyer Hall). There were 645 total Bores for the three locations totaling an estimated 558,600 lineal ft of 1" u-bend pipe and many miles of horizontal piping. Each power plant has multiple Bore fields, with Straumanis-James topping out with six separate locations.
The geothermal system will be tied into 15 separate campus buildings. These plants will contain screw type heat recovery chillers and serve adjacent buildings with heating water through a new heating hot water distribution system.
Benefits to Missouri S&T:
The system is projected to save more than $1 million in energy savings and operational cost annually. This savings is expected to grow to $2.8 million annually in future years.
