4. Historical Measures Example
Newmarket Public Library: All computers are turned off at closing of the library – approximately 75 computers.
Assumed average 9 hours a day/365 days a year (876kwh/computer) operation of computer vs. 24 hours/365 days/year (328.5kwh/computer). Would see savings of 41,063kwh for 75 computers based on hours and 100 watt load of each computer. Cost savings is based on $0.11/kwh.
TOTAL GHG SAVINGS = 5.5 tonnes of eCO2

5. Current Measures Example
Ray Twinney Rec., Retrofits: Lighting, mechanical, water, envelope and other measures complete - see Honeywell report for summary of detailed measures done on building
Savings seen as reported by Honeywell were: electricity = kwh; and natural gas = 40587m3
TOTAL GHG SAVINGS = 128 tonnes of eCO2

6. Current Measures Example
Fleet – purchasing of new equipment: generator replaced by static and dynamic inverter. Staff can operate power tools, pumps and lighting off battery power eliminating the need of a gas powered generator.
To get a figure for reduction in idling due to inverter - look at Idle Free Zone Calculator - 1 min/day of idling = 0.02 tGHG, 4 hour a week (208hrs/yr) = 12, 480 min*0.02=249t/yr of GHG
TOTAL GHG SAVINGS = 250 tonnes of eCO2

7. Current Measure Example
Smart Commute: Employee commuter program - trip reduction program - promotion of walking, biking, taking transit and carpooling to work. Alternative work arrangements (AWA).
Total km saved and recorded: 33,797km – assume fuel efficiency of vehicle - use Canadian Average midsize vehicle of 9.1L/100km = 3075L of fuel savings
TOTAL GHG SAVINGS = 7 tonnes of eCO2
