When calibrating an energy model to utility bills the utility bills often don?t align with the month start and end. I have reviewed a couple methods to calendar normalize the utility bills but find them somewhat unsatisfactory.
For example the method I am looking at does the following:
The April gas bill runs from March 25 ? April 24. The algorithm takes the average number of m3 per day from that bill, applies it to the days in April. Then it takes the average number of days from the May bill which runs from April 24 ? May 25 and applies that average to the remaining days in April.
The issue is that the March-April period has much higher HDD than the April-May period and the ?normalized? gas usage is significantly lower than the simulation data for April.
I am wondering if there are any papers or other sources of information as to how others approach this problem.
