When asked how we handle different days (holidays, weekends, etc) I was told my answer was useful.So, I thought I better write it up. If you agree it's useful, please do feel free to circulate.
Here is how we treat different days treatment-of-occupancy-and-holidays as a two pager...
In short it says:
Different days have different consumption patterns (based on holidays, meter reading failures, weekends, opening hours etc). This will make a nonsense of energy management statistics that do not handle these issues correctly. So a) this is how we do it, and b) if you are considering buying investing or otherwise paying for tools to help manage your buildings, you may want to check these issues.
To make the blindingly obvious yet more obvious, imagine you compare this month with the same month last year to assess performance.
Imagine there are a different ratio of weekends to week days - does this screw up your calculation, how about the Easter holiday shutdown ( a movable feast) or what about a meter reading failure - how can you know your calculations make sense ?
In the simplest case there may be more days (my wife was born on 29th February - so I only have a quarter of the number of birthdays to forget - so far I have a 50% record in eight years - not shabby IMHO:)
