Elevating Efficiency

Seattle University’s carbon footprint continues to shrink. Earlier this month it was announced that SU is the first Puget Sound Energy commercial customer to offset 100 percent of its emissions from natural gas consumption (see "Dung Deal"). Last week, the university further deepened its commitment to conserving resources by outfitting two of its buildings with new equipment that will make them more energy efficient ultimately lower the university’s utilities costs.

New expansion tanks were placed in Bannan and a flue was installed for a new boiler plant in Loyola. The work is part of a hot water loop upgrades project that includes the installation of seven new boilers in the Loyola mechanical room and the connection of Casey and Engineering to the existing heating loop. The output from the Loyola boilers will be dispersed to all buildings in the heating loop including Casey, Loyola, Engineering, Bannan and Biology. 

The effort is expected to significantly reduce the university's greenhouse gas emissions, says Cal Ihler, associate director of facilities operations and maintenance. He estimates the project will remove 616,000 pounds of carbon dioxide from the atmosphere annually.

Ihler adds: "The small-footprint, high-efficiency,  modular condensing boilers now being installed will allow for redundancy if a failure of one boiler occurs. The boilers have an excellent reliability record with other local users and require minimal maintenance."
