Energy Efficiency?

Energy Efficiency Misconceptions

Sustainable Energy Efficiency Measures

Economically efficientPromotes occupant well being

Responsive to the environment

Real energy efficiency in schools

does not take away from safety,

health, security, or comfort.

It’s All About…Reducing Energy Waste!

As much as 25% of building

energy use is wasted.

Why is that?

Why Energy is Wasted

Some problems are invisibleNot aware of the significanceDon’t know what to doSometimes not easy or convenient

Don’t always rememberSometimes counter incentives

This is why an energy efficiency program is needed.

What does a program do?

Articulate goals and their valueCreate systematic plans to solve problems

Evaluate and analyze what to doCreate awareness, learning, and motivation

Monitor, track, and respond

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.

Top 10 No-Cost WaysTo Lower Your School’s Utility Bills

1. Establish and communicate a policy2. Benchmark your school3. Assign responsibility for common areas4. Establish a recognition program5. Control classroom thermostats6. Use building automation systems (BAS)7. Turn off outside lighting8. Establish a plug load plan9. Keep doors and windows closed10.Control exhaust fans

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

ES = $2250 MS = $3000 HS = $4500

2. Benchmark Your SchoolFour Easy Steps

1.Go to www.energystar.gov and register for

a Portfolio Manager account.2.Add a “property” (your school).3.Add a “space” (your school space

attributes).4.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

Example: Portfolio Manager

Example: Portfolio Manager

Challenges A school can have as many as a dozen“meters” (electric, gas, fuel oil, districtheating or cooling, etc.). Bills are usually sent directly to the finance office.

Opportunities Some meters can be read directly by schoolstaff or students. Assign the school’s Portfolio Manager account toa staff member, student intern, or teacher that volunteers(math science, vocational, technology, exceptional).

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

4. Establish a Recognition ProgramAppreciation for a job welldone.Award ceremonies givevisibility to the programRecognize energy saving behaviors at staff and facultymeetings.Encouraged to help and see it as a priority.

ES = $1500MS = $2000 HS = $3000

5. Control Classroom ThermostatsManual

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

6. Use Building Automation Systems (BAS)Control System Capabilities

*Requires a technician

ES = $3000MS = $4000 HS = $6000

7. Turn Off Outside Lighting (Midnight to 6 AM)Purpose of outside lighting

A dark campus seems to deter vandals Dark or lit does not seem to make a difference for larcenies

ES = $1875MS = $2500 HS = $3750

8. Establish a Plug Load PlanPlug Load Management Plan1. PC power settings2. PC security patch management3. Vending machine power control4. Seasonal Shut down5. Refrigerators6. Kitchen equipment7. Water Heaters8. Standby power

1. Use of power strips2. Unplug when not in use3. Office equipment4. ENERGY STAR rated

ES = $1500MS = $2000 HS = $3000

8. Establish a Plug Load Plan (Continued)

Plug loads can account for as much as 20% of the power load in schools.

9. Keep Doors and Windows ClosedPenetration in the building envelope can increase the cooling and heating load of mechanical equipment.

1. Positive PressureMost schools are designed forPositive pressure. Open windows (orImproperly sealed) cause conditioned airTo vent to the outside.

2. Inspect O/A DampersOutside air dampers can be stuck in

the open position.

ES = $1500MS = $2000 HS = $3000

10. Control Exhaust FansWhen the building’s ventilation system is off, exhaust fanscan create a negative pressure.Negative PressureOutside air can enter through

numerous cracks and holes inthe building envelope – briningin unwanted temperatures and humidity levels.

ES = $1500MS = $2000 HS = $3000
