Hays CISD developed an energy management program from 2003-2010 that resulted in a 44.5% reduction in electricity consumption. The program repurposed $3.7 million in savings to fund vehicle replacement, hire energy staff, and fund projects with average paybacks of 3.6 years. By 2010, 20 of the district's 22 campuses earned Energy Star ratings for reduced energy usage.

5. 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.

6. Hays CISD Energy Management
Program
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.

7. 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.

8. 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.

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.

18. 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.

19. 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.

20. Vampire March

21. 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.

22. 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.

23. Energy Star Cont.
• Energy Star buildings use
35% less energy and
generate 35% fewer
greenhouse gas emissions
than similar buildings across
the nation.
