  • Hays CISDDevelopment of Energy Management or “How do you eat an Elephant” answer ‘One bite at a time” 2003 to 2010

  • Hays CISD• Hays Consolidated Independent School District runs between Austin and San Marcos along IH 35 covering 225 square miles, 22 campuses and totaling almost three million square feet of facilities.• Critical people to begin an Energy Management Program is the CFO and School Board.
  • Hays Consolidated Independent School District
  • History of Energy Management Hays CISD• In 2003, Hays CISD was audited by the Texas School Performance Review (TSPR). Two findings of the TSPR audit were that Hays CISD needed a funding mechanism to replace the trucks in the maintenance fleet. Second, Hays CISD needed to develop an energy management program.
  • Hays CISD Energy Management ProgramOur energy management program is a Hays CISDschool board approved process with the followingactions:•All campuses built prior to 2002 would have abenchmark electricity cost of fiscal year 2002-03.This campus dollar amount would become thebenchmark point for these campuses and fundedas such. All campuses built after 2002 will befunded at $1.00 per square foot for electricitycosts. Savings are calculated based on these twofactors.
  • Hays CISD Energy Management Program cont.• In 2003 electricity consumption was 16.57 kWh per square foot. In 2010, electricity consumption was reduced to 9.21 kWh per square foot or a 44.5% reduction in electricity consumption. Over those years, building square footage increased 96.5% but the total amount of electricity used increased only 8.5%.• During the eight years of the Hays CISD energy management program, Hays CISD has repurposed $3.7 MILLION.• In December of the following fiscal year, electricity savings are allocated as follows: – 10% of the electricity savings return to the campus. – 15% of the electricity savings is placed in fund balance to offset any future electricity rate increases.
  • Hays CISD Energy Management Program cont. – 25% of the electricity savings to fund vehicle replacement or equipment for maintenance and operations. Maintenance and operations vehicle fleet replacement was completed in 2008. We will purchase enough vehicles each year for the future to continue in updating our vehicle fleet. – 25% of the electricity savings to hire new personnel for energy management. We have hired two energy management technicians in this category. – 25% of the electricity savings to fund energy management projects.

Evening maintenance has expanded to 13 personnel and covers all maintenance trades. The Energy Management Team includes three coil cleaners, one DDC technician, EM electrician, two PM technicians and an energy management supervisor.
  • Energy Management Team• The ‘billboard for energy management” bus was unveiled in 2007 and serves as a rolling workshop for energy management, remaining visible on a campus having energy management retrofits.
  • Campus and Student Led Energy Initiatives• Initiated “Vampire March” program raising awareness of energy reduction at the campus. Initiated first competition for energy awareness between campuses for unplugging appliances in the classrooms during the Christmas Holidays in 2010 and Spring Break of 2011. Prizes awarded were $3,500 for Christmas Break and $1,500 for Spring Break. Green Team participation key force in utility reduction.
  • Vampire March
  • Student led Energy Projects• Approved expanding student led initiatives in environmental sustainability practices. – In Spring of 2012, student led competition between classes at each campus. – Campus students will design the sustainability program based on the “flavor” of each campus. – Winning class at each campus wins $250. – District will provide posters, banners, stickers for the winning programs at each campus. – Cost for program $6,800.
  • Energy Star Program• In 2010, Hays CISD submitted thirteen campuses to the Energy Star program for consideration. All thirteen campuses were selected as Energy Star buildings. Early in 2011, two campuses were submitted and selected as Energy Star buildings. In the later part of 2011, two additional campuses where selected as Energy Star Buildings. Finally, in 2011, three campuses are in the process of certification of Energy Star. This will bring our Energy Star Portfolio to 20 of 22 campuses rated Energy Star.
  • Energy Star Cont.• Energy Star buildings use 35% less energy and generate 35% fewer greenhouse gas emissions than similar buildings across the nation.

  • FMXcellence Award• "Building Operating Management magazine created the FMXcellence Recognition Program to acknowledge facility management teams that have added significant value to their organizations. The facility management function can play an important role in achieving results for the organization, and FM departments that achieve strong results deserve praise. We selected five facility management teams for FMXcellence recognition in 2011. They represent some of the best work being done in the field today." Ed Sullivan, editor “Building Operating Management”.
  • Energy Efficiency Expo 2011• The Hays CISD Energy Management program was highlighted as a case study during the ‘Energy Efficiency Expo”, held in Nashville Tennessee in September 2011.
