UPDATE: Saving Costs & Reducing Our Carbon Footprint

The first phase of UTakeCharge demand-side energy management and conservation projects was launched in October 2007 to reduce energy and water consumption through targeted renovation and replacement projects. These projects were completed by the end of January 2009.

A measurement and verification program* based on industry standards has been used to measure and verify energy and water savings for the projects. Here’s a brief overview of results:

Lighting

  • Project began in May 2008 and was completed in January 2009.
  • Retrofit more than 183,000 lighting fixtures and installed 2,300 occupancy sensors.
  • Projected savings per year:
    • 28 million kWh/year of electricity (equal to 95,536 MMBTU)
    • 5 megawatt reduction in peak demand power (equal to 17.06 MMBTU/Hr)
    • 24 million pounds of carbon dioxide
    • $1.9 million per year at current billing rates (at Austin Energy and University of Texas billing rates)
    • Annual electric energy savings will be equivalent to energy used by more than 1,500 local, average-size homes.
  • The methods used in measuring and calculating energy savings from the lighting upgrades on the Main and J. J. Pickle Research campuses are described in the Savings Calculation for Lighting*.
  • Building-by-building results are tabulated in the Lighting Savings Summary*.

Steam

  • Project began in July 2008 and was completed in December 2008.
  • Replaced or repaired 420 steam traps and radiator valves.
  • Projected savings per year:
    • 23,480MMBTU of steam energy savings
    • 5.8 million pounds of carbon dioxide
    • $235,000 (at University of Texas billing rate)
  • Annual energy savings will be sufficient to provide heat and hot water to 706 local, average-size homes.
  • Methods and results of energy savings calculations for steam system upgrades on the Main and J.J. Pickle Research campuses are described in the Savings Calculation for Steam*.

Water (domestic and process)

  • Project began in July 2008 and was completed in January 2009.
  • Replaced, repaired, or installed 5,941 plumbing fixtures, including aerators, showerheads, urinals, toilet valves, and tanks and bowls.
  • Projected savings per year:
    • 60 million gallons of water
    • 288,000 kWh (pump power)
    • 246,000 pounds of carbon dioxide (pump power)
    • $572,000
  • Annual water savings equates to a one-year supply of water for 831 local, average-size homes.
  • The methods used in measuring and calculating water savings from upgrades to domestic water fixtures on the Main and J.J. Pickle Research campuses and installation of laboratory process cooling equipment on the Main campus are described in the Savings Calculation for Water*.
  • Building-by-building savings are tabulated in the Water Savings Summary*
