Hi all,
I'm making a register to track energy savings since installing skylights in some buildings and need to summarise the data (in a table and then graphically represent). The light usage for each building is tracked daily, and I need to sum 7 days of information based on the week ending date. Eg. If the date of the week ending is the 7th June 2013, I need to sum the 1st-7th June for each house.
I can manage the formula manually, but I need a formula that I can drag down to go on for several years if required (as I will not be managing this forever).
I have attached the workbook, and the 'Light Usage' tab is the same data as the House 1 and 2 (just in a different format). I had trouble with the formulas due to the format in the 'Light Usage' tab, but this would be the preferred tab to keep if possible (rather than having 2 or more).
Any help is much appreciated!
