Ways to save and manage energy in your
facilities
5Why do we care about energy?
- World electricity demand is expected to double
between 2000 and 2030 - The greatest increase will occur in the
developing world - Electricity production is the leading cause of
industrial air pollution in the United States,
and is responsible for 40 percent of the nation's
carbon emissions that contribute to global
climate change
6Why do we care about energy?
- At most, 35 percent of coal's energy in a power
plant converts to electricity - The remaining two thirds is lost as waste heat,
benefiting no one and often harming surrounding
ecosystems - Where electricity is produced from coal, each
fluorescent light bulb used prevents 1,300 pounds
of CO2 emissions and 20lbs of sulfur dioxide,
1.7lbs mercury, 2.3lbs arsenic, and more from
being pumped into the atmosphere - Why do we care? Over 50 of US electricity comes
from burning coal
7Energy Conservation
- Economically Efficient
- Conducive to the Learning Environment
- Responsible to the Environment
- Energy Efficiency in Schools should not
compromise the health, security and safety of the
building occupants

20Energy Management Keys to Best Practices
- Utility Management
- Need to know how much you use before you can
determine how much you can save - Energy Star Portfolio Manager Baseline
- Review and Approval Utility Bills
- Energy Use Audit of Each Facility
- Building Occupancy Profiles
- Building Characteristic and Systems
- Information needed to determine energy goals
and set specific targets for an Energy Management
Plan
21Energy Management Best Practices
- Understanding of EMCS System
- Develop and Obtain Approval of Energy Policy
- Develop an Energy Regulation
- Develop an Energy Management Plan
22Energy Management Best Practices
- Develop and Obtain Approval of an Energy Policy
- Short Document 2 or 3 short paragraphs
- Include a statement of purpose
- .. Provide leadership in developing a
realistic energy ethic in the operations of our
facilities . Success is the joint
responsibility of governing body, administrators,
teachers, students and all organizations
personnel and is based on their cooperation. - Policy should include CEO/President/Superinte
ndent is responsible to implement . And
Administrators will be evaluated on the success
.. - Sample copy available
23Energy Management Best Practices
- Regulations to Implement Policy
- Regulations can state specifics about the
operations of energy systems in your buildings - Regulations can establish accountability
- Regulations can include the establishment of
- Energy Manager Position and a Energy Mgt Team
- Establishment of an incentive program
- Establishment of a reporting and evaluation
system
24Energy Management Best Practices
- Development of an Energy Management Policy
- Statement of Purpose Guide the operation of
the agency to achieve the highest standards in
energy/water use/environmental and economic
performance - State Goals --- .. X percent reduction in
energy use for each facility by the FY 20xx
20yy.. - Can be in several areas including training and
education - Sets Objectives to achieve Each Goal
25Plug and Phantom Loads
- What is a plug load?
- How best to control plug
loads? - What is a phantom load?
- Means of controlling phantom loads?
26What are Plug Loads?
- Plug loads are electrical devices or appliances
that draw power through an electric outlet - Schools typically have 120/208-volt electrical
systems with many different loads - A load is any device that is powered by an
electrical system and requires electricity to do
work - Many appliances and devices that are turned ON
- Anything that has an ON/OFF switch can be a load
and managing the use of these loads can help save
electricity and money.
27Examples of plug loads
- printers and scanners
- fax machines
- copiers
- fish tanks
- overhead projectors
- ranges and stoves
- vocational equipment
- refrigerated drinking fountains
- clocks
- coffee makers
- computers/monitors
- fans
- desk and table lamps
- microwaves
- refrigerators
- televisions
- VCRs
- window air conditioners
- vending machines
28How Much Electricity Do Plug Loads Use?
- Up to 20 percent of the total electricity
consumed by a school is from plug loads. - Managing the use of such equipment can greatly
reduce a schools electricity consumption.
29How to control plug loads
- Need to conduct a plug load survey
- Educational Needs
- Energy Awareness Training
- Develop Energy Guidelines for plug loads
- Include fees for personal items
- Have teeth in the Guidelines
30What are Phantom Loads
- Phantom loads exist in equipment with
- electronic clocks or timers, with remote
controls, portable equipment and equipment with
wall cubes - Consumes Energy even when turned off
- Also known as Stand-by Power and Leaking
electricity - This equipment can consume energy from 3 to 25
watts per hour when turned off - 2.50 to 10 per year per device
31How to control Phantom Loads
- Disconnect devices at the end of day
- Plug into power strips and turn power strips
off at the end of the instructional day - Education
32How Much Energy is Being Wasted behind closed
doors?
33- Standard 75kVA
- VS.
- Energy Efficient Transformer
- The difference is at least 7 x 100W light bulbs
- Would you leave the lights on for 50 years ?

40Does High Performance Schoolequal anEnergy
Efficient School ?
- NOT NECESSARILY!
- People operate buildings, buildings do not
operate themselves - Energy awareness and knowledge are the keys to
success - EDUCATE! EDUCATE! EDUCATE!
41Must quantify energy usage and feasibility of
reducing it
42Level I Energy Audit
- A Level I Audit is a walk-through survey of a
facility to assess current energy cost and usage
and to determine energy savings potential for
effective energy efficiency measures - The audit identifies energy efficiency measures
necessary to achieve such savings potential for
capital intensive projects and low-cost/no-cost
measures - The audit provides a savings and cost analysis
and simple payback period of all measures
recommended
43Level II Energy Audit
- A Level II Audit includes a more detailed
building survey and energy analysis. A breakdown
of energy use by system is required - The facilitys equipment and systems are reviewed
to evaluate and confirm equipment and system
operating profiles, methods of control, equipment
efficiency, and changes of facility energy usage
that have occurred or are anticipated - The audit identifies low-cost/no-cost operations
and maintenance procedures and capital equipment
and installation costs, with calculations to
support energy savings, costs, and simple payback
period or life cycle cost analysis
44Level III Energy Audit
- A Level III Audit consists of a detailed analysis
of capital intensive measures that follow the
same basic steps as the energy audit described
above, but includes detailed analysis and
calculations and/or modeling to determine the
viability and interactive effects of potential
energy efficiency measures identified - The audit requires identification of capital
equipment and installation cost, calculations to
support energy savings and costs, and simple
payback and life cycle cost analysis - This audit requires a detailed scope of work and
understanding between parties
45Small Actions,
Large Results
- How can an
- Energy Audit
- benefit you?
46What is an Energy Audit?
- Through an inspection of your facility, we will
survey and analyze all aspects of energy
consumption - Building envelope
- Lighting and electrical equipment
- Heating and mechanical equipment
- All energy consuming systems
During the inspection we are looking for
opportunities in which to reduce the amount of
energy put into your system.
47What is an Energy Audit?
After the inspection, we then create an inventory
of all consumption items and the usage patterns
of the buildings. Next, we calculate the energy
being consumed and the amount that would be
consumed if changes to devices and usage patterns
were implemented.
48Our main concern in an ENERGY AUDIT is to find
ways to save you money while maintaining or
improving the health, safety, and comfort level
of the occupants.
49We guarantee we can find energy savings
opportunities or the Energy Audit is free!
