Our Mission at CEW
• Mission Statement
CEW empowers people to take an active role in restoring and sustaining nature. We give communities the tools for education, monitoring and influencing positive change. Together we create a healthy environment for all.
•Vision Statement
CEW envisions a future where we are a leader in empowering individuals and communities to actively protect and maintain a healthy, sustainable environment for future generations.

The Approach
Student-driven energy conservation program
• Step 1: Audit
• Step 2: Action
• Step 3: Monitoring
&
Evaluation
5
Step 1: Audit
• Check utility bill or electricity meter
• Divide class into groups, with each group in charge of a particular zone in the school
• Measure ALL appliances in use within each zone
6
Step 2: Action
• Analyze energy data per zone
• Develop Energy Conservation Plan
• Develop overall strategies for energy reduction
• Develop goals, research, brainstorm- focus on doable strategies
• Develop a plan to implement your strategies
• For things that are not „doable‟- create a list of recommendations to school administration
7
Step 3: Monitoring and Evaluation
• Continuation of action plan
• Monitor utility bill or meter
• Submit your Conservation action plan to CEW in order to qualify for our Grand prize payout towards your action plan
• At the end of the school year- calculate grand savings and GHG emission reductions
8
In-Class Workshop ~1 hr
• Introduction
• What is Wattwize
• Three steps of
the program
• Terminology
• Introduce Wattmeters
• Student‟s measure using Wattmeters
• Explain Calculations
9
Wattmeters
• Measures different units of electricity ie: Volts, Amps, Watts
• Keeps a memory log when appliance is plugged
• Calculates kWh and Cost
10
Create ways to Share and measure your success
• Create a poster display
• Create an Energy hog, or Watt busters ticket system
• Create a high impact award system for those that stick to the strategies to meet the goals
• Oral presentations at Assemblies or school-wide gatherings
• Have weekly updates at morningannouncements
11
Students’ Home Energy Audit
Assign students a home energy audit based on the work they‟vedone with Wattwize in their school
• STEP 1 – AuditUse your watt meter to measure several key appliances in your home. Example – computers, televisions, microwave
• STEP 2 – Plan Use these measurements to create a plan to decrease your energy use at home. Example – Turn your computer off at night, use a power bar
• STEP 3 – Monitor and EvaluateKeep track of the changes you have made and the approximate savings on your energy bill. Example – If you can save 4-5 kWh a week, that is roughly a savings of $5, and over the course of a year you could save over $250!
13
• 2000 students
• 2 campuses
• 130 staff members
• Special programs in sports, music, environment, co-op…a really busy place.
Dunbarton High School
Grade 9 Science
• Rationale to admin
• Get the kids organized
• Go to work
• Results

Goals
• Educational – enrichment for SNC1D4 students in the areas of communication, problem solving, project management, public presentation skills, data analysis and environmental literacy.
• Curriculum – tied to Grade 9 Science Characteristics of Electricity unit; implementing Wattwize will cover 9 SNC1D expectations.
• Institutional – reduce DHS electricity consumption by 4% (Kipling collegiate, a smaller school, decreased consumption by 7.7%)
15
Project Tasks
• Small groups of students will use Wattmeters to measure the electricity consumption of every plug-in device in every room of the school.
• Total school lighting load will be calculated.
• An electricity conservation plan will be prepared by the students.
• The conservation plan will be “promoted/marketed” to staff and students.
• After conservation plan is implemented electricity consumption will again be measured and results (hopefully positive) reported.
16
Issues / Needs
• Access -on a few occasions to the main school power meter.-to every room and every device – momentary interruption of teaching/office work during the afternoon.
• Buy-In- Staff are key – we will need them to cooperate with the intrusions and to then support and promote the eventual conservation plan which will mostly require behaviour change (turn things off). Can we come up with some sort of reward
based on eventual energy savings?
• Electricity Bill- money seems to matter a lot so if we can get the power bill
we can translate 4% savings into cash for the school (does the school keep any savings or will it go the Board?)
17
Get the Kids Organized
Groups and Tasks
• In-Class Training
• Wattwize Wednesdays
• Results
18
Get the kids Organized
Tasks for Peer Helper1. Divide the school into 6 zones based on location and
roughly equal workload.
2. Make a table/worksheet for each group outlining each room number in the zone, and the name of each teacher who uses the room during each period of the day.
3. Identify the rooms in each zone on an attached school map for each zone.
4. For non-classrooms, find out what the room is used for and who can provide access
19
Get the Kids Organized
• Six groups each assigned a school zone
• Each group visits every room
• Each group member has a role
1 = Custodial/Cafeteria (Chartwels) Liaison
2 = Student (SAC) Liaison and DDSB/CEW Liaison
3= Teacher Liaison
4 = Admin/Office Staff Liaison
5/6 = Researcher

SNC1D4 Wattwize
Initial Findings
From The Power Bill
- DHS Annual Electricity Cost:
$174 797 (year to August 2006)
– DHS Annual Consumption:
1 674 808 kWh (enough electricity to run a 100 W light bulb for 1912 years, or the output of all six operating reactors at the Pickering Nuclear station for about 35 minutes)
22
Results
Measured School Power Consumption:
• Campus Nov 28 kWh Dec 5 kWh Total kWh Annual kWh
• North 0733 0783 20049
• South 1970 1885 9914
• Total: 29 963 1 558 076
• this is 93% of the value in the bill. The difference is probably air conditioning which was not on for our meter reading.
23
Results
Calculated Phantom Load
• Total Phantom Load:
2834 kWh = $320/year
This is very small and is probably substantially
larger.
24
Results
• Difficulties Lead to Questions
-Some appliances have unpredictable on/off cycles (fridges).-Computers on and off at unknown intervals.-Ballasts in each fluorescent fixture use from –2W to 25W (not part of our calculations)-Many rooms are frequently unoccupied (washrooms, offices, storage closets)
25
Results
• SO WHAT…
If Dunbarton reduced electricityconsumption by ONLY 5% each year wewould…-Save about $9200.
-Reduce Carbon Dioxide Pollution by 26 Tons. -Free Up Electricity For 167 Refrigerators.-Power 7 houses for a year.

Utility Room Lighting Audit
Project Summary
• To identify potential electrical savings by installing motion sensitive light switches in all offices, washrooms, gymnasiums, change rooms and storage rooms in the North Campus.
• March 11 2009 - Scheduled to present findings to DDSB Facilities Services Manager and Ontario Ecoschools Coordinator
28
Utility Room Lighting Audit
Survey• 59 rooms were identified• 78 individual light switches were in these rooms• these switches controlled 769 34W light bulbs.
Assumption• each light bulb is on for 9 hours each day (8am to 5
pm)• all bulbs are 34W• motion senstiive switches would cut power use inthese
rooms between 25% and 50%.
