unthsc cumulative savings Sustainability initiatives often
start with energy since it is central to issues in environmental
conservation. UNTHSC’s goals are to reduce energy consumption and make the campus more energy efficient. Since
1999, the campus has been investigating ways to accomplish these goals
and has saved the university millions of dollars through energy
efficiency efforts (click on the picture to the right).

Energy Savings Performance Contract: Phase I

UNTHSC
began aggressive energy conservation efforts in 1999 when it completed a
detailed energy audit for several of the buildings on campus. In 2001, a
feasibility study was completed concerning the implementation of solar
power on campus, but was concluded to not be a cost effective energy
source at the time.

In 2001,
UNTHSC contracted with Tour Andover Controls (TAC), now Schneider
Electric, to complete a two phase guaranteed energy conservation
project. Phase I included:

  • Lighting efficiency improvements
  • Replacing two chillers
  • Installing direct digital controls
  • Domestic water conservation efforts

Phase I was a $3.2 million project
financed through the Texas Public Finance Authority’s Master Lease
Purchase Program. A measurement and verification plan was put in place
along with training of university personnel. The energy and water
reductions exceeded expectations and performance guarantee and resulted
in a total cost avoidance of $1,577,844 as of 2006. According to EPA
figures, the utility savings resulted in a reduction of CO2
emissions by approximately 25,425 tons, the equivalent of removing 5,085
cars from the road annually or planting 6,916 acres of trees.

Energy Savings Performance Contract: Phase II

In 2010, UNTHSC began phase II of the Energy Savings Performance Contract with Schneider Electric. Phase II included:

  • Motion sensor lights
  • Window replacements
  • Energy efficiency lighting in the buildings and parking garages
  • Installing a computer power management system
  • Mechanical upgrades to several building chillers
  • Installation of a new water management package

Phase II was an $8.6 million
guaranteed and self-funded investment. This phase was forecasted to save
$835,000 annually, pay for itself in 10.3 years, and create $2.7
million in positive cash flow for the university. The environmental
impact includes a reduction of over 2,400 tons of CO2 annually.
