ENERGY + INNOVATION 10 No-Cost Ways to Lower Your Schools Utility Bills Tim Tolman| McKinstry | January 16, 2009 FOR THE LIFE OF YOUR BUILDING
3
What do we mean by Energy Efficiency? Energy Management – Basic Concepts
4
Energy Efficiency Misconceptions Cold in winter Hot in summer Dimly lit room
5
Sustainable Energy Efficiency Measures Economically efficient Promotes occupant well being Responsive to the environment Real energy efficiency in schools does not take away from safety, health, security, or comfort.
6
Its All About… Reducing Energy Waste! As much as 25% of building energy use is wasted. Why is that?
7
Why Energy is Wasted Some problems are invisible Not aware of the significance Dont know what to do Sometimes not easy or convenient Dont always remember Sometimes counter incentives This is why an energy efficiency program is needed.
8
What does a program do? Articulate goals and their value Create systematic plans to solve problems Evaluate and analyze what to do Create awareness, learning, and motivation Monitor, track, and respond A technical part & a people part Guidelines for Energy Management
9
How do schools use Energy? Energy Management – Basic Concepts
10
Understanding Energy Use in Schools How much does your school spend each year on energy? Elementary School: $50,000 to $100,000 Middle School: $75,000 to $125,000 High School: $100,000 to $200,000
11
Understanding Energy Use in Schools How much can your school save each year on energy? Potential No-Cost Savings 10% Elementary School: $50,000 to $100,000 ~ $7,500 Middle School: $75,000 to $125,000 ~ $10,000 High School: $100,000 to $200,000 ~ $15,000
12
The Savings Value Meter Savings potential for no-cost measures 1% to 10% Each of the 10 measures that we present will have this value meter. The metric being used is % of overall energy bill. The orange arrows indicate a potential for the average school. The red arrows represent the potential for the limited number of schools that might be more vulnerable to the condition described in the measure. There are many factors that can affect the actual outcome of your efforts – results can vary widely.

Our definition of No – Cost : Incidental activities No purchases required No extensive labor effort

Top 10 No-Cost Ways To Lower Your Schools Utility Bills Measures: Programmatic Heating, Ventilation and A/C (HVAC) Lighting Plug loads Building envelope
16
Top 10 No-Cost Ways To Lower Your Schools Utility Bills 1.Establish and communicate a policy 2.Benchmark your school 3.Assign responsibility for common areas 4.Establish a recognition program 5.Control classroom thermostats 6.Use building automation systems (BAS) 7.Turn off outside lighting 8.Establish a plug load plan 9.Keep doors and windows closed 10.Control exhaust fans
17
1. Establish and Communicate a Policy Connection to business plan Roles and responsibilities Temperature set points Use of computers/equipment (schools & personal) Vacation shutdown guidance Benchmarking Awareness and training Sustainable Energy Efficiency committee ES = $2250 MS = $3000 HS = $4500
18
2. Benchmark Your School Four Easy Steps 1.Go to www.energystar.gov and register forwww.energystar.gov a Portfolio Manager account. 1.Add a property (your school). 2.Add a space (your school space attributes). 3.Enter at least 12 months of energy use data. You will receive a rating (from 1 to 100) that compares your school with a national average (50). ES = $2250 MS = $3000 HS = $4500
19
Example: Portfolio Manager
20
Challenges A school can have as many as a dozen meters (electric, gas, fuel oil, district heating or cooling, etc.). Bills are usually sent directly to the finance office. Opportunities Some meters can be read directly by school staff or students. Assign the schools Portfolio Manager account to a staff member, student intern, or teacher that volunteers (math science, vocational, technology, exceptional).
21
3. Assign Responsibility for Common Areas Common Areas Hallways Multipurpose rooms Cafeterias Auditoriums Restrooms Gymnasiums Locker rooms Conference/meeting rooms Stage Storage areas ES = $2250 MS = $3000 HS = $4500
22
4. Establish a Recognition Program Appreciation for a job well done. Award ceremonies give visibility to the program Recognize energy saving behaviors at staff and faculty meetings. Encouraged to help and see it as a priority. ES = $1500 MS = $2000 HS = $3000
23
5. Control Classroom Thermostats Manual Set for comfort during class time Establish range (e.g. 72 to 78 F) Set back at night and weekends (by 8 to 10 F) Programmable Establish range Periodically inspect settings Over-rides 1 Degree = 1% Energy Cost ES = $3750 MS = $5000 HS = $7500

6. Use Building Automation Systems (BAS) Control System Capabilities Program settings Assess trouble prior to dispatch Optimize system settings * *Requires a technician ES = $3000 MS = $4000 HS = $6000
26
7. Turn Off Outside Lighting (Midnight to 6 AM) Purpose of outside lighting Staff safety Crime prevention Extra-curricular activities National Crime Prevention Council 350 Tested Strategies to Prevent Crime A dark campus seems to deter vandals Dark or lit does not seem to make a difference for larcenies ES = $1875 MS = $2500 HS = $3750
27
8. Establish a Plug Load Plan Plug Load Management Plan 1.PC power settings 2.PC security patch management 3.Vending machine power control 4.Seasonal Shut down 5.Refrigerators 6.Kitchen equipment 7.Water Heaters 8.Standby power 1.Use of power strips 2.Unplug when not in use 3.Office equipment 4.ENERGY STAR rated ES = $1500 MS = $2000 HS = $3000
28
8. Establish a Plug Load Plan (Continued) Plug loads can account for as much as 20% of the power load in schools.
29
9. Keep Doors and Windows Closed Penetration in the building envelope can increase the cooling and heating load of mechanical equipment. 1.Positive Pressure Most schools are designed for Positive pressure. Open windows (or Improperly sealed) cause conditioned air To vent to the outside. 2.Inspect O/A Dampers Outside air dampers can be stuck in the open position. ES = $1500 MS = $2000 HS = $3000
30
10. Control Exhaust Fans When the buildings ventilation system is off, exhaust fans can create a negative pressure. Negative Pressure Outside air can enter through numerous cracks and holes in the building envelope – brining in unwanted temperatures and humidity levels. ES = $1500 MS = $2000 HS = $3000
