Summary

In 2003, NV5 teamed with Iowa State University to design a satellite chiller plant that housed one 4,000-ton steam turbine chiller with provisions to install an identical chiller. In 2016, additional chiller tonnage was required to support a fast-growing campus and the favorable electric rates from a MISO grid connection made adding electric chiller capacity to this plant economically viable. Ultimately, two chillers in series-counterflow and parallel arrangement, totaling 7,000 tons, were chosen. NV5 worked with the University to analyze operational data, confirm space constraints and make necessary utility upgrades inside and outside the plant. Chillers are projected to come online July 2018 and will provide substantial operational savings, utility resiliency, and operational flexibility. Challenges and resolutions will be part of the presentations.
