Knowing Your Building
SchoolDude University 2009
• Knowing Your Building
– How Schools are Operated?
• Without knowledge of energy use
• Impact of individuals actions
• No Energy Policy/Regulation
• No approved Energy Management Plan
• Limited Preventive Maintenance
• Lack of involvement by personnel
SchoolDude University 2009
• How Schools are Operated?Education is Key to the Success of Any Program
--Energy Awareness of allSchool Staff
SchoolDude University 2009
• What is Energy Management?– A process to obtain an Understanding of:
• Building Utilization• How energy is being consumed• Energy Systems Installed
– A process to:• Improve overall energy efficiency and reduce
impact on the environment– Goal to Improve Learning and Teaching
Environment
SchoolDude University 2009
• What is Energy Management?– Understanding of Building Utilization
• What areas are used and when?• Patterns of occupancy and habits• Space compatible with programs and energy
efficiency– How’s the Energy is being consumed?
• What are the light levels?• Identifying Plug and Phantom Loads• HVAC equipment operations – EMCS• Electrical Systems

Another View of Energy Consumption in Schools
SchoolDude University 2009
• Energy Management Keys
– Utility Management – Need to know how much you use before you can determine how much you can save
• UtilityDirect – The Best on the Market – On Line– Available for information and an instructional tool
– Energy Star Portfolio Manager – Baseline– Review and Approval Utility Bills– Energy Use Audit of Each Facility– Building Occupancy Profiles– Building Characteristic and Systems– Result – Information needed to determine energy goals
and set specific targets for an Energy Management Plan
SchoolDude University 2009
• Energy Management Keys– Understanding of EMCS System– Develop and Obtain Approval of Energy
Policy– Develop an Energy Regulation– Develop an Energy Management Plan
SchoolDude University 2009
• Energy Management Keys– Develop and Obtain Approval of an Energy Policy --
Foundation for EMP• Short Document – 3 or 4 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 “… Superintendent is responsible to implement …. And administrators will be evaluated on the success …..”
• Sample copy available
SchoolDude University 2009
• Energy Management– Regulation to Implement Policy
• Regulations can state specifics about the operations of energy systems in your buildings
• Regulation can establish accountability• Regulation 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• Samples available
SchoolDude University 2009
• Energy Management – Development of an EMP
• 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

What is a plug load?
How best to control plug loads?
What is a Phantom load?
Means of controlling Phantom Loads?
Plug and Phantom Loads
SchoolDude University 2009
• Define plug loads– Educational Devices or appliances
plugged into a school’s electrical system
– 120/208 volt electrical systems– Examples in schools: Copiers, Refrigerators,
Pop Machines
– Examples in the classroom:• Computers, TV’s, DVD Players, Tape Players,
overhead Projector,• Boom Box, Radios, CD players, printers, scanners,
copiers, fish tanks, mini-refrigerators, toasters, coffee pots, hot plates, overhead projectors, LCD projectors
SchoolDude University 2009
• How 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
Energy Guide for Plug Loads
SchoolDude University 2009
• Define Phantom Loads– Phantom loads exist in equipment with
electronic clocks or timers, with remote controls, portable equipment and equipment with wall cubes
• Consumes Energy when turned off– This equipment can consume energy from
3 to 25 watts per hour when turned off– Also known as “Stand-by Power” and
“Leaking Power” – Wall Cubes Big “Phantoms”
SchoolDude University 2009
• How to control Phantom Loads– Disconnect device after every day– Plug into power strips and turn power strips off
at the end of the instructional day– Education
SchoolDude University 2009
• Factors Impacting Energy Use and Management– Outside Factors
– Educational Factors
– Design Factors
– Budgetary Factors
SchoolDude University 2009
• Increasing Energy Unit Costs (+)• Energy Crisis (+)• Increase Community Use (+) K-12• Changing Demographics (-/+) K-12• Changing Technologies (-)
Outside Issues Impacting Energy Use
SchoolDude University 2009
• Smaller Class Size (+) K-12• Year Round Schools (+)• House or Cluster Concept (+) K-12• Computer Based Programs (+) • More Instructional Programs (+)
Educational Issues Impacting Energy Use
SchoolDude University 2009
• Characteristics & $ Benefits of HP Design(-)
• Shared Facilities (-) • Design Standards (+/-)• High Performance Design Elements (-)
Design Issues Impacting Energy Use
SchoolDude University 2009
Budgetary Issues Impacting Energy Use
• Reduced Budgets, Personnel (+)
• Decreased Capital Budgets (+)
• Disconnect of Capital and Operating Budgets (+)
• O & M (+/-)
SchoolDude University 2009
• Benefits of EMP
– Reduces Energy Consumption– Reduces Energy Costs– Reduces Environmental Impact at Source– Increases Energy Awareness of Personnel– Serves as a Educational Tool– Serves as an Example for the Community
SchoolDude University 2009
Does HP School = Energy Efficient School ?
NO People operate buildings, buildings do not operate themselves
Energy awareness and knowledge are the keys to success
EDUCATE! EDUCATE! EDUCATE!
SchoolDude University 2009
Energy Management Here; EM Now –
Means Tapping the
Energy Waste in Schools
And Remember--
SchoolDude University 2009
In today’s world, improving the energy efficiency of educational facilities should be the goal of the district to support the nation’s goal of Energy Independence. EM Now; EM Here; Payless -- should be heard throughout the nation’s schools.
Will this be heard in your schools? Explore the possibilities and potential!
It’s Not Rocket Science
Bottom-line
