Utilities

Facilities Services is responsible for the management of all utilities - electric, natural gas, steam, and water - for the Frost, Medical Center, and Downtown campuses.

Spring 2014 saw Facilities Services' Strategic Action Team, Energy and Utilities Strategies, finalize reduction goals for energy and water consumption on campus. To meet these goals, Facilities Services is actively implementing sustainable energy and water practices.

Energy

Energy Goal: 20% reduction in energy intensity (BTU/GSF) by 2020 from the 2013 Baseline

Energy Graph

The graph above shows the average decrease required each year to achieve the University's goal, shown by the line, compared to the actual consumption for each year, represented by the power lines.

Energy Projects: Below are a few of the energy projects that have been implemented

  • Building Sub-Metering: Many of SLU's buildings are clustered onto one electric meter. Sub-metering has been installed on many buildings to collect individual energy consumption numbers for tracking and analysis.
  • Occupancy Sensors & Vending Misers
    • Occupancy sensors for room lighting have been installed throughout campus to improve the energy efficiency of those buildings.
    • In 2010, 105 vending machines were equipped with Vending Misers to manage the machine's lighting and compressor cooling cycles. The installation reduced energy usage by 157,000 kWh annually, for a savings of $10,229. 
  • LED Nativity Scene Christmas Lights: 2013 saw an upgrade for the Nativity Scene display located on the Medical Center Campus from incandescent to LED lighting. This upgrade saves 81.6 kWh of energy each night for a operational savings of $277.00 for the seven weeks the display is standing.
  • Young Hall Auditorium: In 2014, Facilities Services replaced the auditorium lighting with LED bulbs. This upgrade saves 37,370 kWh of energy for an annual cost savings of $2,997.

 

Water

20% reduction in potable water consumption (gallons/campus acre) by 2020 from the 2013 baseline

Water Graph

The graph above shows the average decrease required each year to achieve the University's goal, shown by the line, compared to the actual consumption for each year, represented by the water bottles.

Water Projects: Below are a few water reduction initiatives that have been implemented

  • Building Sub-Metering: Many of SLU's buildings are clustered onto one water meter. Sub-metering is being investigated for those buildings to be able to collect individual water consumption numbers for tracking and analysis.
  • Water-Saving Technologies: Where applicable, Facilities Services has installed low-flow faucets, shower heads, urinals, and toilets.
    • Low-flow faucets use on average 30% less water than conventional faucets
    • Current plumbing codes in St. Louis City and St. Louis County prohibit the use of water-free urinals
  • RainBird's Maxicom2 Irrigation Management System: This centralized control system manages the operation of the irrigation system to reduce water usage, for example the system is capable of suspending irrigation if it is raining or just recently rained.
  • Rainworks Stormwater Management Garden: In 2014, four civil engineering students designed and were awarded a grant from MSD to install a stormwater management garden on the east side of Busch Student Center, which is prone to erosion. 
    • SLU's Grounds Department installed the garden
    • It is projected that the garden diverts 7,473 cubic feet of water from the combined sewer system

Measurement and Tracking Initiatives:

  • 25 X 20 Voluntary Energy Benchmarking Pledge: This initiative ties seamlessly with Facilities Service's energy and water reduction goals.     
    • Launched by the High Performance Building Initiative, which is coordinated by the St. Louis Regional Chamber and U.S. Green Building Council - Missouri Gateway Chapter 
    • SLU joins University of Missouri - St. Louis and Webster University by taking the pledge
    • Aligns with the City of St. Louis' goal to reduce greenhouse gas emissions by 25% by 2020
    • According to Energy Star data, companies that benchmark have an average energy savings of 7% over three years
  • FAMIS: Facilities Services is in the process of implementing the FAMIS Utilities module which will allow for a more complete and concise collection of SLU's utility data.
  • Metasys Building Automation System: The system has been configured to enable night setbacks as well as unoccupied and centralized operation of remote buildings.
    • It is used to turn air handlers and pumps on and off according to the scheduling needs for a particular building or zone within a building
