Energy Conservation Tip #1
Always turn off all lights when you leave a room or when they are not needed. It is
estimated that 26% of a building’s electricity is used for lighting. For D-11 this equals $650,000
annually. This makes lighting one of our biggest opportunities for energy savings. Most D-11
buildings have already been converted from T12 lights to T8 lights saving the district
approximately $350,000 per year. The use of natural day lighting or turning off lights while
using projection equipment can help increase our savings. But the biggest savings are to just
turn them off when you leave the room!
Energy Conservation Tip #2
Unplug electrical devices when they are not in use. This includes projectors and amplifiers,
cell phone chargers, coffee pots, etc. It is estimated that up to 25% of electricity in schools is
used by plug load. Plug load is anything that draws power from an electrical outlet. Many
devices continue drawing electricity from the outlet even when they are turned off. The best
energy conservation practice is to unplug electrical devices when they are not in use. Please
remember safety first and refrain from unsafe activities like climbing on chairs to unplug
projectors.
Attached is a link to student educational curriculum on plug load that provides additional
information and an example of how to estimate plug load:

Energy Conservation Tip #3
Report heating, ventilating, and air conditioning (HVAC) equipment that does not
shutdown during unoccupied times with a work order. It is estimated that 40% of a
building’s energy is used by the HVAC system. This number can be much higher when the
system is working extended hours. You should hear air moving during occupied times. This is
because D-11 schools continuously bring in fresh air during the school day to insure excellent
indoor air quality. Conditioning fresh air requires large amounts of energy. Now is a great time
to identify malfunctioning equipment so it can be repaired before the heating season. You can
also have your building managers verify that the exhaust fans in your restrooms are shutting off
at the end of the day. If something doesn’t seem right, please contact your Building Manager or
Principal for submission of a Work Order since this allows us to track all repairs.
Energy Conservation Tip #4
Do your best to get lights, electrical devices, and HVAC systems in your building shutdown by
4:00 pm. Electric rates nearly double in many of our building between 4:00 and 10:00 pm
October through March. This is known as the on-peak demand period. Having a large electrical
demand during this time period for just one day of the month can cost hundreds and sometimes
thousands of dollars. By keeping our demand lower during this time we can reduce the cost of
the electricity we use during the day when school is in session. Avoid scheduling optional
events from 4 pm to 10 pm October through March, if possible.
Energy Conservation Tip #5
Dress accordingly for the outdoor temperatures and layer clothing to help improve your comfort.
Heating, ventilating, and air conditioning (HVAC) set points generally fluctuate a minimum of 4
degrees (± 2 degrees) due to equipment capabilities. Fall and spring present additional
challenges for our HVAC systems. We generally need heating in the morning and air
conditioning in the afternoon. Many of our HVAC systems are not capable of switching from
heating to cooling instantaneously. Some large units are controlled off an average temperature
of numerous rooms meaning some will be hot and some will be cold. The problem may be
more noticeable than at home because air flows continuously during occupied times to supply
your space with fresh air. Please understand that the temperature in your area may not always
be exactly where you desire it to be. Layering clothing is your best defense against temperature
fluctuations.
Energy Conservation Tip #6
Be sure to keep exterior doors and windows closed while the heating and cooling system is in
operation. Leaving doors and windows open while at recess can cause your system to work
overtime. In some cases more than one room is tied to one thermostat. In these cases leaving
doors or windows open can cause your neighbors to be too hot or too cold in addition to wasting
energy. Heating is the largest utility expense in D-11!
Energy Conservation Tip #7
Please don’t tamper with thermostats or heating/cooling overrides. Tampering with overrides
may provide you temporary results, but often causes discomfort in the long run. Remember to
keep books, etc. off of heating and cooling equipment, especially where it blocks airflow. If you
are experiencing an operational problem with your heating and cooling equipment please
contact your building manager so a work order can be created and the problem resolved in the
most appropriate and permanent manner.
Energy Conservation Tip #8
Reducing air leaks in your building is one of the easiest ways to save energy. In addition to
saving energy, preventing air leakage also improves occupant comfort and indoor air quality.
You can help by looking for air leaks around exterior doors and windows. Report damaged or
leaky windows and doors to your building manager so plans can be made for their repair.
In homes it is estimated that 25 to 40% of heating and cooling energy is lost to air leaks.
Attached is more information on how you can save energy at home too.

Energy Conservation Tip #9
Colorado has over 300 days of sunshine each year. We can all take advantage of this great
resource to help heat our buildings. During heating season open your blinds during the day
when the sun is shining to help heat your building. Then close your blinds at the end of the
day to help keep the heat in. When summer approaches and we begin the cooling season you
will want to reverse these steps.
Energy Conservation Tip #10
Please turn all computers and monitors completely off when they are not being used for more
than 2 hours and at the end of the day. When shutting down your computer please allow
updates to install when prompted. Computers may be left on Thursday evenings for updates.
Shutting down computers is estimated to save approximately $20 / computer / year. D-11
already achieves some of this savings by setting all computers and monitors to enter sleep
mode when they are inactive for a few minutes. Shutting down computers when they are not
needed offers additional savings. D-11 operates over 13,000 computers meaning these savings
can really add up.
Energy Conservation Tip #11
Thanksgiving Break Shutdown 2010
Thank you for practicing D-11’s energy conservation tips. With your help this year is sure to be
our best year for energy savings yet. Below is a list of reminders for the upcoming Thanksgiving
holiday. Please do your best to complete the following tasks prior to leaving your building for
the Thanksgiving holiday:
9 Turn off all classroom and office lights.
9 Turn off all computers.
9 Insure exterior doors and windows and tightly closed with blinds closed.
9 Turn off and unplug all office equipment (photocopiers, toasters, coffee makers, etc…)
except printers
9 Turn off projector equipment, amplifiers, etc…
9 Clean out and unplug all personal refrigerators.
9 Unplug all personal space heaters.
LTTs and LTEs:
9 Turn off computer CPUs, monitors, and other related equipment.
Building Managers/Kitchen Managers:
9 Be sure thermostats in portables are setback.
9 Please do not shutdown cafeteria/kitchen point of service machines they will be remotely
shutdown by Food Services.
9 Unplug all vending machines that are not needed by building staff or community
activities over the break.
9 Verify all kilns and exhaust fans are off.
9 “Team Clean” one area of the school at a time so that lights can be turned off in other
areas.
9 Deploy pool covers.
Energy Conservation Tip #12
Look for additional electricity savings opportunities like reducing artificial lighting. One
opportunity exists in hallways with glass to the outside. In these areas, interior lights may be
turned off when natural day lighting is sufficient. Another opportunity is to report exterior lights
on you building or parking lot that come on before the sun goes down or stay on once the sun is
up. You can report these to you building manager so a work order can be created. Please
remember to only use the lights in the areas in which you are working after hours. Electrical
costs consume 50% of D-11’s annual utility budget. This means our best opportunity for
savings is from reduced electrical consumption. Reducing electrical consumption also has the
largest effect on reducing our carbon footprint.
Energy Conservation Tip #13
Be sure your building manager schedules work orders for after hours holiday events and
performances. This will ensure you have heating and ventilation for your event. When
requesting a work order, be sure to identify the specific space you will be using as well as the
precise times. This will help facilities best support your event. When scheduling for multiple
spaces needed, always try to consolidate the activities into the same area of the building to
reduce the amount of equipment needed. Your building manager and the facilities department
can help you determine the best location to hold activities if desired.
Christmas Break Shutdown 2010
All: Thank you again for practicing D-11’s energy conservation tips. All of your hard work is

Below is a list of reminders for the upcoming Christmas holiday. Please do your best to
complete the following tasks prior to leaving your building for the holiday:
9 Open cabinets below sinks to prevent freezing pipes in cold weather.
9 Unplug all holiday decorations.
9 Turn off all classroom and office lights.
9 Turn off all computers.
9 Insure exterior doors and windows and tightly closed with blinds closed.
9 Turn off and unplug all office equipment (photocopiers, toasters, coffee makers, etc.)
except printers

9 “Team Clean” one area of the school at a time so that lights can be turned off in other
areas.
9 Deploy pool covers.
Energy Conservation Tip #14 – Combating Cold Weather
Please do your best to help prepare for cold weather. You can help by leaving cabinets below
sinks open during cold weather to prevent pipes from freezing. You can also layer clothing to
stay comfortable while your heating system catches up. When a building heating system is off
over the weekend, it takes a little longer to warm the mass of the building on Monday morning.
Please try layering clothing and giving your building a little extra time to warm up before calling
in a work order. Extreme conditions can present more work orders than we have resources to
handle. A little extra time can alleviate some work requests by helping maintenance personnel
to prioritize and respond more effectively. Cold weather is also a great time to identify and
report leaky doors and windows to your building manager for repair. Remember your heating
system is near its maximum capacity during extreme cold so don’t prop or leave doors open.
Energy Conservation Tip #15 – Watering
Please do your best not to attach a hose to your building for spring watering and cleanup. Most
people don’t know that D-11’s irrigation systems are metered separately from our building
water. When you attach a hose to your building for watering, D-11 pays twice as much for that
water. This is because we pay sewer fees on building water. For concerns with your buildings
landscape please be sure look to the District’s Grounds Shop for professional help.
