NOTES:
Savings represent the difference between the corrected use of the Reference House, and the actual use of Test House with load reduction measures as implemented, and without the offsetting PV generation included
Saving from implemented measures: kWh = total savings over the 6-hr period considered; (%) = average of hourly percentage savings for the 6-hr period considered
Days with * were transition days between periods with different measures, for clarity we do not report savings data for these days
