Universities can spend substantial amounts of money heating and cooling large campus buildings. For Dominican University of River Forest, IL, that wasn’t acceptable, especially during the summer months.
Kevin Amyot had serious qualms last spring when contractor Ed Friedrich first proposed a major pump-retrofit project at the Sunset Motor Inn, one of the properties Amyot manages for the H. A. Manosh Corporation in Morrisville, VT. Friedrich’s $13,000 estimate called for the replacement of 18 fixed-speed circulating pumps in the heating system at the Sunset with 10 circulators from the Grundfos Pumps Corporation.
Identifying motor retrofit opportunities in cooling towers, air handlers, exhaust fans, and
circulating pumps reflects the no-stone-unturned strategy Rutgers employs in energy management.For those motors, boiler upgrades, and future projects, the university regularly seizes on multiple incentives opportunities — ranging from utility offers to good old-fashioned intraschool competition — to teach efficiency in action.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
