History of Energy Management History of Energy Management Hays CISDHays 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 Hays CISD Energy Management ProgramProgram
Our energy management program is a Hays CISD school board approved process with the following actions:•All campuses built prior to 2002 would have a benchmark electricity cost of fiscal year 2002-03. This campus dollar amount would become the benchmark point for these campuses and funded as such. All campuses built after 2002 will be funded at $1.00 per square foot for electricity costs. Savings are calculated based on these two factors.

• 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.

– 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.

Energy Management Team Evening Maintenance
• The Energy management Team began in 2003 with one coil cleaner in an evening maintenance program. 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 ProgramEnergy 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.
