ACCOMPLISHMENTS

Any successes of Facilities Management’s Sustainability Plan would not be possible without the support and cooperative efforts of the agencies in each building. In addition to upgrading the building’s mechanical and technological aspects, it is imperative that state agencies work together to develop a culture to improve building sustainability. 

Efficiency begins with individual participation and behavior.

Results (FY08 vs. FY09):

Total energy reduction: 35,224,619 kilo-British thermal units (kBtu) (16.9%)

Total electricity reduction: 6,234,882 kilo-watt-hours (kWh) (13.9%)

Total natural gas reduction: 12,859 Dekatherms (Dth) (29.9%)

Total water reduction: 3,906,000 gallons (7%)

Due to higher costs-per-unit, the 16.9% reduction of energy use contributed to cost-avoidance instead of money saved. 

  • Total of $673,779 in costs-avoided

Contributing Projects:

  • Many lighting improvements were made including the replacement of 17,307 T-12 fluorescent light tubes with more efficient T-8 tubes in four foot fluorescent fixtures.
    • The upgrade switched a 20,000 hour life bulb (T-12) to a 36,000 hour life bulb (T-8) resulting in an 80% longer life.
    • The retrofit also earned $34,614 from OG&E energy efficiency rebates!
  • A delamping process has removed over 1,300 unnecessary, fluorescent light tubes from many common area fixtures.
  • 24-hour emergency lights in the Will Rogers building are now equipped with LED tube lights.
    • Exit signs were also converted to LED throughout Capitol Complex.
  • Over 200 lighting control devices were installed in low-traffic areas and in some offices.
    • These devices minimize electricity use by use of either timer switches, occupancy sensors, or daylight sensors.
  • The ability to control and monitor the efficiency of equipment in state buildings is vital to any sustainability efforts. This is made possible through innovative programming strategies used in correlation with new controls and sensors for the Building Management System (BMS).
    • Reduced hours of operation for natural gas-requiring Heating Ventilation and Air Conditioning (HVAC) equipment.
  • Installed low-flow urinals & toilets, faucet aerators, and many touch-free & timed-flow restroom fixtures.
  • The state-operated buildings that OFM is tracking on Energy Star have shown a 15% rating increase:
    • Average rating for all buildings in June 2008: 56.8
    • Average rating for all buildings in May 2009: 66.8
      • Ratings based on efficiency of operations compared to similar buildings in region.

To inform tenants of Sustainability Projects and to further minimize the environmental impacts of state-operated buildings, Facilities Management has developed the Green Fingerprint energy awareness campaign. The ‘Green Fingerprint’ concept represents what DCS is actually doing to curtail the environmental and monetary repercussions of wasteful energy use. 

Leaving a Green Fingerprint means we are making a difference for the preservation of our future.

  • One of the first initiatives of the Green Fingerprint campaign was a light bulb exchange. Through the cooperation of building occupants, this exchange provides energy-saving Compact Fluorescent Light (CFL) bulbs to replace high-wattage, incandescent bulbs in desktop lamps.
    • DCS has replaced over 2,268 incandescent bulbs with CFL bulbs in state-operated buildings.
    • Official results of the Earth Day CFL Exchange: 
      • Total bulbs replaced: 2,268 
      • Total watts removed: 106,954 watts
      • Total kWh avoided: 102,675.84kWh per year
      • Approximate cost avoided: $8,214.24 per year
      • Approximate CO2 emissions avoided:177,100 lbs per year
        • Calculated using lamps an avg. of 4 hours/day & cost of electricity $.08/kWh.
    • The electricity saved in the CFL Exchange is enough to:
      • Run a microwave oven 24 hours a day for 10 months!
    • The CO2 emissions avoided in the CFL Exchange could:
      • Occupy the volume of 5,906,000 official-sized basketballs!
