16.9% decrease in electricity use in 2012
when compared to baseline year of 2009!!!!!
Brilliant stuff

e – Lift Station Main

e – Service Center - awesome
Note – please ignore Oct-Dec 2012 consumption. Planet Footprint are still
waiting on 48 days of billing data for this period. The ‘spike’ is due to that period
being estimated based on historically higher consumption. It can be expected
that when 2012 data set is complete consumption for Oct – Dec 2012 will be
much lower.

GAS (NATURAL)
– TOP CONSUMING SITES
2012 expenditure was $61.2K

G - % CHANGE
Across the board decreases in consumption!!!
But was it the weather?
14
G – Heating Degree Days

Heating Degree Days
Heating degree day (HDD) is a measurement designed to
reflect the demand for energy needed to heat a building. It
is derived from measurements of outside air temperature.
The heating requirements for a given structure at a specific
location are considered to be directly proportional to the
number of HDD’s at that location. A similar measurement,
cooling degree day (CDD), reflects the amount of energy
used to cool a home or business.
Please note that degree days are calculated by multiplying
the difference in degrees from base temperature by the
number of days. E.g if July 1 was 5 degrees lower than the
base temperature for that day this would equate to 5 HDD –
that’s why the number of ‘days’ can exceed the real number
of days in a month.

G – HDD plotted with consumption (ccf)
Yes – it looks like it was the weather. There is a direct correlation between mains
gas consumption and HDD. The more HDD the more gas is used.
