DAILYUSECACLUATIONWOKRSHEET:

Step 1 – Find and copy your school’s “baseline”, provide by DPS Go Green

__________________________________ Our school’s baseline (Average daily use)

Step 2 – Take a meter reading at a specific time during the day

__________ X ___________ = __________________ Kw h Multiplier 1st meter reading

Step 3 – Take a 2nd meter reading at the same specific time a number of days later

__________ X ___________ = __________________ Kw h Multiplier 2nd meter reading

Step 4 – Subtract your 1st meter reading from your 2nd meter reading

_________________ - ________________ = __________________ 2nd meter reading 1st meter reading Energy used

Step 5 – Divide the energy used by the number of days between readings

_____________ ÷ ____________________ = ___________________ Energy used Days between reading Average Daily Use

Step 6 – Compare your actual average daily use that you calculated in step 5 to your school’s baseline from step 1! If you have more than one meter, repeat steps 1-5 and add the daily uses together to compare to the baseline.

___________________ - __________________________ = ______________

Baseline daily use (step 1) Meter reading daily use (step 5) Daily energy savings

Step 7 – See how much you are saving. Average cost for electricity at DPS is $0.106/KWH.

(KWH) X $0.106 = ___________________ Energy Saved per day Electricity Cost Daily savings ($)

Discussion Questions

Is our daily use above or below the baseline?

______________________________________________________________

Does that mean we are using more or less energy than the baseline?

______________________________________________________________

How much more or less (as a percentage)?

______________________________________________________________

If we measured during a school break, how does that affect the daily use? Did we power down before that break?

______________________________________________________________

______________________________________________________________

______________________________________________________________

If we measure before and then after our energy saving campaign, can we see the effect of our efforts?
