Brilliant stuff

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.

G - % CHANGE

Across the board decreases in consumption!!! But was it the weather?

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.
