Efficiency Upgrades

Several energy conservation programs have been implemented on campus:

Chiller Upgrade

In 2001, a four-phase upgrade to the south chiller plant was drafted. In each phase an older chiller is removed and replaced by a new, more efficient system.

In 2006, phase two was completed. A new 2,000-ton chiller, cooling tower, and two pumps replaced two aging 800 ton chillers. One benefit of the new equipment is that it uses a zero ozone-depleting potential refrigerant, R134a (HFC), instead of R11 found in older chillers. This is part of the university's policy to phase out all CFC refrigerants in accordance with the Montreal Protocol.

The fourth and final phase was completed in 2010, giving the university twice the chilling capacity with a greater operating efficiency.

Steam Distribution and Recovery Pipeline Insulation

To improve steam distribution efficiency, Facilities Management commissioned an energy consulting group to conduct an audit. The primary recommendation was to improve insulation on both the steam and condensate pipe lines.

By doing so, the report suggests the Power Plant would significantly reduce its fuel consumption to the tune of about $70,000 each and every year. Even more impressive is the fact that the payback on the project could be realized in as little as 1.8 years. The project wrapped up in 2008.
